Description

Description: TECHNICAL FIELD The present invention relates to a condenser for an automobile used in an air conditioner for an automobile, and particularly to a structure of the condenser for an automobile and an attachment structure suitable for attachment to a vehicle. Regarding the improvement of.

[Conventional technology]

A conventional device is to provide a mounting bracket in the bracket for holding the upper and lower fins of the automobile condenser as described in JP-A-62-175588, and as another method, both sides of the automobile condenser. There is also a method of fixing the condenser bracket made of iron to the automobile condenser and the mounting bracket by welding the fixing bracket and the fixing bracket to each other.

[Problems to be Solved by the Invention] In the above-mentioned JP-A-62-175588, if the plate thickness is made thin in order to improve heat transfer efficiency and reduce refrigerant passage resistance and fin portion ventilation resistance, the strength is lost and It is difficult to cope with the vibration that accompanies traveling. Further, the method of setting the iron fixed brackets on both sides of the condenser for automobile has many drawbacks such as a large number of parts, a large number of manufacturing steps, and a high product cost. Moreover, in the fixed bracket, iron (Fu) is mainly used at present due to its durability and welding with the mounting bracket, so the condenser for automobiles is made of aluminum, so the corrosion resistance is reduced due to the joining of dissimilar members, and the weight is high. There was a problem such as heavy weight. Further, since the pipe portion protrudes from the outside of the condenser, it is likely to be deformed due to portability, and particularly in a product such as an automobile, which is being automatically assembled by a robot, there is a problem that it becomes a bottleneck for automatic assembly due to deformation.

An object of the present invention is to provide a condenser for an automobile capable of solving the above-mentioned problems that occur with respect to the attachment structure of the attachment bracket and the condenser for the automobile.

[Means for Solving the Problems]

The above object is to provide a pair of spaced refrigerant accumulation parts, one of which has a refrigerant inlet and the other of which has a refrigerant outlet, a plurality of tubes arranged in parallel between the refrigerant accumulation parts, and the tubes. A condenser provided with a plurality of fins for transmitting heat of a refrigerant to another, and a reinforcing member arranged between upper end portions and lower end portions of the pair of refrigerant accumulating portions. In the configuration configured to be fixed to a supported body through a bracket attached to the condenser, the refrigerant accumulating portion, the tubes, the fins and the reinforcing member are formed of aluminum members, and the bracket is U-shaped. Alternatively, a pipe formed of an aluminum material in an L shape, the bracket being attached to at least one of the refrigerant storage portion and the reinforcing member by brazing and provided between the refrigerant storage portion and the refrigerant inlet / outlet portion. It is achieved by providing the inside of the reinforcing member.

[Action]

By forming the components of the condenser and the mounting bracket from the same material, that is, an aluminum material, brazing can be performed in the integrated furnace.
As a result, the weight is reduced and the joining of dissimilar members is eliminated, the corrosion resistance is improved, and the number of parts is reduced as compared with the conventional condenser, so that the manufacturing cost is reduced and the product cost is reduced. Further, since the reinforcing member is bridged between the refrigerant accumulating portions provided on both sides of the condenser and the mounting brackets are integrally attached to both of them, the refrigerant accumulating portion can be held and the strength is improved. Further, since the piping is formed integrally with the case, it is not changed during handling or when it is mounted on a supported base such as an automobile.

〔Example〕

 An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a refrigerant storage portion provided on both sides of the condenser, and a plurality of tubes 2 for flowing a refrigerant therebetween.
And a plurality of fins 3 for transferring heat of the refrigerant to the other. Generally, the tubes 2 and the fins 3 are thin because they are thin in thickness in order to improve the heat transfer efficiency and reduce the resistance of the refrigerant passage and the ventilation resistance of the fins. Therefore, for the purpose of improving the strength, the reinforcing member 4 is provided between the refrigerant accumulation portions on both sides.
To provide. The reinforcing member 4 may be formed in a U-shape or an L-shape for the purpose of improving the strength, and may be integrally formed by brazing or the like at the ends of the refrigerant accumulating portion at both ends. Reference numeral 5 is a mounting bracket, which has the shape shown in FIG. 2 when the press is removed, and is molded into two pieces as shown in FIG. 3, or is molded with a die cast or the like to form the refrigerant storage portion 1 and the reinforcing member. 4 are integrally formed by brazing or the like. Generally, since a plurality of attachment points are provided, such brackets are provided at a total of four locations at both ends of the refrigerant storage portion 1 at both ends.
Reference numeral 6 denotes a refrigerant inlet / outlet portion, and a refrigerant passage is formed by a pipe with both portions of the refrigerant accumulating portion 1. The pipe 7 is as if inside the U-shaped or L-shaped reinforcing member 4 as shown in FIG. The reinforcing member 4 is mounted so that most of the reinforcing member 4 is housed as if it were a component of the condenser body. Further, even if the pipe 7 cannot be housed in the reinforcing member, it will be advantageous if the pipe 7 is housed inside the above-mentioned two-piece mounting bracket.

FIG. 5 is an example of another embodiment, and the two pieces of the mounting bracket 5 can be combined with each other by combining two separate parts without forming two integrated parts.
This is an example in which individual pieces are used and combined.

FIG. 6 is an example of another embodiment, and when it is used in an application that does not require relatively high strength or when the entire condenser is light,
The mounting bracket 5 may be composed of only one sheet, not the two sheets, and may be formed integrally with the refrigerant accumulating portion 1 and the reinforcing member 4.

FIG. 7 is also an example of another embodiment, and the mounting bracket 5 may be integrally formed only in the refrigerant accumulating portion 1 if the reinforcing member 4 is made to have a strong plate thickness.

〔The invention's effect〕

According to the automotive condenser of the present invention, the constituent parts of the condenser and the mounting bracket are made of the same material, that is, aluminum material, so that the brazing can be performed in the integral furnace, so that the weight can be reduced and the productivity can be improved. As a result, it can contribute to the reduction of the total weight of the automobile and the improvement of fuel consumption. Similarly, since different members are not joined, corrosion resistance is improved. Further, unlike the conventional case, it is not necessary to join a fixed bracket and a mounting bracket to a condenser for an automobile and to scratch or pierce a fin constituting the condenser at the time of mounting the fixed bracket. As a result, the ventilation area is reduced with fixed brackets that sacrifice the fins at both ends, which leads to higher heat exchange efficiency without increasing ventilation resistance. Furthermore, since the number of parts constituting the automobile condenser is reduced, the manufacturing cost is reduced and the product cost is reduced. In addition, by forming the mounting bracket in a U-shape and an L-shape, the inlet and outlet pipes can be arranged between the U-shape and L-shape, interference with other automobile parts can be prevented, and the protection and appearance of the pipe can be improved. As described above, the automobile condenser of the present invention has the above-mentioned effects.
