Description

[0001]
[Industrial application fields]
The present invention relates to a heat exchange device that moves a heat medium in a controlled manner, for example, a downflow roof that diffuses and appropriately distributes a flowing down heat medium. In particular, the present invention relates to a heat exchange device for a surface to be bonded which is continuous in a strip shape in the lateral direction and has a step in the longitudinal direction, for example, a flat roof. Specifically, if warm water is allowed to flow along the heat exchange device in the form of this roof, snow can be removed or melted in the winter in the winter, solar heat can be collected in the summer, and cold water can be collected. Can be used to cool the roof.

[Prior art]
2. Description of the Related Art A flow regulating member that regulates the flow of a heat medium by alternately providing a main flow path and a sub flow path on the surface of a member in a streak manner is well known.
[0003]
[Problems to be solved by the invention]
FIG. 6 is a cross-sectional explanatory view showing a state in which a conventional sheet-like flow down regulating member is attached to a flat roof. First, the problem of such a setting member is that since the roof elements are subdivided, the individual elements undergo relative positional fluctuations, and the roof surface is slightly stretched and deformed. Since the flow regulation means is affixed in a form that covers the roof surface, irregular shearing force acts on the adhesive surface of the flow regulation means, and the flow regulation means may peel off or the front of the flow regulation may be distorted. .
[0004]
Secondly, the restraint performance of the heat medium is greatly affected by the construction accuracy of the adherend surface and the quality of the mounting posture of the regulating member itself. Specifically, the upper and lower lateral strips overlap each other on the adherend surface of the laying structure in which the plane is continuous in a strip shape in the horizontal direction like a flat structure surface and the upper strip strips cover the joints in parallel. The portion forms a stepped step, and the slope of the regulating member at a position exceeding the step changes temporarily with each flow path as a boundary at the lower edge of the belt-like portion. Therefore, in the regulating member at this location, if the flow path is not perpendicular to the lower edge, the flow path changes its direction obliquely and the flow surface is inclined.
In the case of roofs that are manually crafted with goby joints and stacked vertically, unlike horizontal roofs, horizontal accuracy will not be relied on. It takes time and is not familiar with the field work.
[0005]
Further, as a third problem of the regulating member, when a flat roof is taken as an example, the overlapped step is about 10 mm, and the flow regulating member at this point is in a non-contact state over the roof surface. It is in. Accordingly, the gap between the upper and lower roof members is closed by the flow regulating member to form a closed space. If rainwater enters the enclosed space from the side edge of the adjacent regulating member, the inside becomes wet, and the metal plate may corrode due to condensation and cause water leakage. Further, water that has entered the space stays in the interior, and if the amount is large, there is a risk of water leaking from the gouge joint due to the siphon phenomenon.
[0006]
[Means for Solving the Problems]
A strip-shaped surface element that is continuous in the horizontal direction is arranged in parallel vertically, and the roof surface is formed by covering the roof surface in a form that covers the upper edge of the lower planar element at the lower edge of the upper planar element, and covers this roof surface In order to supply the heat medium onto the flow-down regulating means that is bonded to the roof surface across the stepped portion of the planar element and flows down the heat medium, and the flow-down regulating means disposed above the flow-down regulating means. Heat medium supply means. The flow-down regulating means changes the direction from the lower edge of the upper planar element so that the position located in the overlapping stepped portion of the planar element changes within the space behind the stepped portion along the return portion on the back side of the upper planar element. A play portion is formed which enters and further turns to reach the upper edge of the lower planar element.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
A flat roof surface formed by laminating strip-shaped surface elements that are continuous in the horizontal direction in a vertically parallel manner and covering the upper edge 2a of the lower planar element 2 with the lower edge 1a of the upper planar element 1 It is used as a support surface for the flow down regulation means 3. A space 4 is formed between the overlapping portions of these surface elements. This space is drawn enlarged for convenience, but in reality, a space of about 6 to 8 mm in height and about 30 to 40 mm in depth is generally used. The size of the space is not constant because it varies depending on the combination of surface elements.
[0008]
The illustrated flow regulation means 3 is in the form of a pressure-sensitive adhesive tape that is adhesively fixed in a form that covers the roof surface with an adhesive previously applied to the back surface. The flow regulation means is for diffusing the heat medium flowing down on the surface so as not to converge.
Various materials are selectively used for the flow-down regulating means. For example, a material that can absorb water, specifically, a woven fabric, a non-woven fabric, a knitted fabric, a sheet material made of a porous membrane, or a membrane material laminated with a water absorbing material can be used.
[0009]
The flow regulation means 3 changes direction from the lower edge 1a of the upper planar element 1, enters the space 3 along the return portion 1b, further changes direction, and passes through the upper edge 2a of the lower planar element 2. Affixed to the surface of the lower planar element. As a result, part of the flow regulation means located in the space forms a play portion with respect to the relative displacement between the flat elements of the roof.
Since this play portion is located obliquely upward along the slope of the roof surface, it has a structure in which rainwater does not easily enter the space.
FIG. 1 and FIG. 2 show in detail the affixed state of the planar element and the flow down regulating means.
[0010]
In the illustrated example, a dish-shaped guide member 5 is installed from the upper edge 2a of the upper planar element 2 to the inside of the space 4, and the flow-down regulating means is disposed so as to overlap a part of this guide member. FIG. 3 shows the guide member 5 alone. The illustrated guide member is coated with an adhesive 5c along the front edge 5a, and the position is fixed from the upper edge of the lower planar element to the space 4 by this adhesive. Moreover, the standing part 5b is formed in the opposite edge part. If a large upright part is provided, the tip part comes into contact with the return part 1b as shown in the figure to partition the space.
[0011]
FIG. 5 shows an example of changing the guide member. The guide member 5 in this example has a pressure-sensitive adhesive 5c applied to the back side of the edge 5a in the same manner as in FIG. 3, and is turned up from the return portion 1b of the upper planar element to the upper surface of the lower edge. An edge 5b is provided. Since the folded edge wraps upward along the lower planar element, a small-diameter passage due to the bulge of the material is formed at the inner front end portion of the folded edge although they both contact. The passage formed at this position is used as a drainage path for entering rainwater. In addition, if a string is passed through along the inner front end portion in the lateral direction, the same effect as that obtained by interposing a passage forming spacer can be obtained. Apart from this, an adhesive may be applied in advance to the inner surface of the folded edge 5b, and the folded edge may be positively bonded and fixed to the lower edge of the lower planar element.
[0012]
As shown in FIGS. 1 and 2, the guide member 5 is bonded and fixed in a state where it is inserted into the space 4 before the flow-down regulating means is attached. For example, the flow-down regulating means encounters a stepped portion of the planar element in the process of pasting while releasing the release paper from the top to the bottom of the roof. The flow-down regulating means located at this step portion is pushed into the space. In FIG. 4, reference numeral 6 indicates a push plate that pushes the flow regulating means into the space 4. This pressing plate 6 has an enlarged portion 6a at the tip edge. The enlarged portion 6a has a cross section that can push the flow-down regulating means into the form shown in FIG.
[0013]
If the push plate 6 is used, the left and right push amounts can be adjusted as indicated by arrows. For example, if the left side of the push plate is pressed more strongly than the right side, the left side of the flow down regulation means enters deeper into the space than the right side. At that time, the flow-down regulating means rotates to the left as shown by the arrow, and the sticking direction can be corrected to the left. Therefore, the direction correction of the flow down regulating means can be performed for each step, and high adhesion accuracy can be secured.
[0014]
The above-described guide member can be provided with a lubricant such as a silicone film or a paraffin film on the front side surface in a state of being installed in a space. Such a film forms a sliding surface against the adhesive of the flow regulating means. Without sticking to the surface of the member, the adhesive surface of the flow-down regulating means smoothly enters the surface of the guide member into the sliding space.
[0015]
【The invention's effect】
By constructing as described above, even if the flow-down regulating means is installed, the step portion of the original roof retains its contour and the aesthetic feeling of the roof is not changed. The application of the flow regulation means is not affected by the roof construction accuracy, and an accurate flow path that allows a relatively small amount of heat medium to flow with regularity can be easily created.
