It was bent so that The molded beverage cooling pipe (2) has a straight pipe portion with a pitch (P) of 6 mm, an overall left and right length (L1) of 410 mm, a meandering vertical width (L2) of 220 mm, and straight pipes at both ends. The length (L3) of the extended portion extending upward from the portion was 100 mm.
Moreover, 3 g / m 2 of a two-component curable polyester polyurethane adhesive (34) was applied to one side of an A8079 annealed aluminum alloy foil (31) classified by JIS H4160 having a thickness of 40 μm, and the thickness was dried. A 12 μm stretched polyester film (33) was bonded, and the other surface of the aluminum alloy foil (31) was coated with 3 g / m 2 of a two-component curable polyester polyurethane adhesive (34). After drying, the thickness was 30 μm. A linear low density polyethylene film (LLDPE) (32) was bonded and cured in a constant temperature bath at 40 ° C. for 3 days to obtain an aluminum laminate sheet (30) (see FIG. 2). The aluminum laminate sheet (30) was cut so that the left and right length (L4) was 420 mm and the vertical width (L5) was 250 mm.
Next, the molded cross-linked polyethylene pipe (20) is disposed on the polyethylene film surface (320) of the aluminum laminate sheet (30) as shown in FIG. The aluminum laminate sheet (30) and the cross-linked polyethylene pipe (20) were heat-sealed by pressing a hot plate heated to 0 ° C. for 3 seconds at a pressure of 0.5 MPa.
Next, the aluminum laminate sheet (30) is rolled into a cylindrical shape so that the cross-linked polyethylene pipe (20) is on the inside, and the polyethylene film surfaces (320) on both left and right edges thereof are overlapped with each other in a width of 5 mm. Heat fusion was performed by pressing a hot plate heated to 200 ° C. from the polyester film surface side of the edge at a pressure of 0.5 MPa for 3 seconds. And the aluminum laminate sheet (30) was shape | molded so that it might become the cylindrical shape of a cross section as close to a perfect circle as possible (refer FIG. 5 and FIG. 6).
Thus, the heat exchanger (1A) of Example 1 was produced.

<Example 2>
The same crosslinked polyethylene pipe (20) as in Example 1 was prepared as a beverage distribution pipe (2), and this was bent in the same manner as in Example 1.
In addition, as the constituent material of the heat transfer sheet (3X), two aluminum laminate sheets (30) same as those in Example 1 were prepared.
Then, in the same manner as in Example 1, the molded polyethylene pipe (20) was heat-sealed to the polyethylene film surface (320) of the first aluminum laminate sheet (30).
Next, the polyethylene film surface (320) of the second aluminum laminate sheet (30) is placed on the right and left sides of the polyethylene film surface (320) of the first aluminum laminate sheet (30) to which the polyethylene pipe (20) is heat-sealed. And a second aluminum laminate sheet (30) by pressing a hot plate heated to 200 ° C. from the polyester film surface side of the second aluminum laminate sheet (30) for 3 seconds at a pressure of 0.5 MPa. The polyethylene film surface (320) of) was heat-sealed to the outer surface of the polyethylene tube (20) and the polyethylene film surface (320) of the first aluminum laminate sheet (30) (see FIGS. 9 and 10).
Next, the two laminated aluminum laminate sheets (30) are rolled into a cylindrical shape, and the polyethylene film surfaces (320) of the joining margins (35) formed on the left and right edges thereof are overlapped, The joining margin part (35) was heat-sealed by pressing the hot plate heated to 200 degreeC from the polyester film surface side of the edge part of the edge part at a pressure of 0.5 MPa for 3 seconds. Then, the two laminated aluminum laminate sheets (30) were molded so as to have a cylindrical shape having a cross section as close to a perfect circle as possible (see FIGS. 11 and 12).
Thus, a heat exchanger (1B) of Example 2 was produced.

<Example 3>
Circular holes (362) having a diameter of 10 mm were formed at intervals of 10 mm in the left-right direction at the upper and lower edges of the two laminated aluminum laminate sheets (30) of Example 2 as heat medium passage holes.
Others were carried out similarly to Example 2, and produced the heat exchanger (1C) of Example 3. FIG.

<Comparative example>
A stainless steel tube having an outer diameter of 6 mm and a wall thickness of 1 mm was bent into a spiral cylinder so that the overall outer diameter was 145 mm, and a heat exchanger of a comparative example was produced.

<Evaluation of beverage cooling effect>
Cooling water was generated by charging 40 liters of tap water and 20 liters of ice into a 40 cm long, 40 cm wide, 40 cm deep stainless steel tank equipped with a stirrer. Then, while the cooling water was stirred by rotating the stirrer, the heat exchanger (1A) of Example 1 was completely immersed in the cooling water in the stainless steel tank so as not to reach the stirrer of the stirrer.
Next, water is supplied to the beverage distribution pipe (2) of the heat exchanger (1A) from one end thereof at a flow rate of 5 liters per minute, and the water discharged from the other end of the beverage distribution pipe (2). Were poured sequentially into five glass cups in 200 ml, and the water temperature in each glass cup was measured.
The heat exchangers (1B) and (1C) of Examples 2 and 3 and the heat exchangers of Comparative Examples were also subjected to the same operation as described above, and the temperature of the water poured into each glass cup was measured.
The measurement results are shown in Table 1 below together with the weight of each heat exchanger.

As is apparent from Table 1, the heat exchangers (1A), (1B), and (1C) of Examples 1 to 3 were significantly reduced in weight with respect to the heat exchanger of the comparative example using the stainless steel tube. .
Moreover, the temperature of the water cooled by the heat exchangers (1A), (1B), and (1C) of Examples 1 to 3 was lowered to a level that was not significantly different from that of the comparative example using the stainless steel tube.

<Evaluation of beverage heating effect>
While continuously supplying heated water heated to 60 ° C. from the outside to a 40 cm long, 40 cm wide, 40 cm deep stainless steel tank equipped with a stirrer, the heat exchanger (1A) of Example 1 was added to the stirrer of the stirrer. It was completely immersed in the heated water in the stainless steel tank so as not to be damaged.
Next, water is supplied to the beverage distribution pipe (2) of the heat exchanger (1A) from one end thereof at a flow rate of 1.5 liters per minute and comes out from the other end of the beverage distribution pipe (2). 200 ml each of the water was poured into three glass cups sequentially, and the water temperature in each glass cup was measured.
The heat exchangers (1B) and (1C) of Examples 2 and 3 and the heat exchangers of Comparative Examples were also subjected to the same operation as described above, and the temperature of the water poured into each glass cup was measured.
The measurement results are shown in Table 2 below.
