合状況を説明する。 In FIG. 2A, reference numeral 1 is a plate made of aluminum, iron, etc., and two plates 1 have a concave groove 2 as a refrigerant passage section, and an adhesive coated part 3 of one of the plates 1 has a concave groove. Further, grooves 6 for preventing the adhesive 5 from spilling out are provided on the flat parts on both sides of the recessed part 4. Next, the joining situation of the two plates 1 having the above configuration will be explained.
初めに第２図Ｂに示すように、接着剤塗布部３

はない。 Next, as shown in FIG. 2C, by overlapping the two plates 1 and flattening the concave portion 4 under pressure, the adhesive 5 is pressurized and flows out to the joint plane portion 3, and the excess adhesive is 5 is stored in the grooves 6 and is not applied to the grooves 2 that serve as refrigerant passages.
次に同じく第２図Ｃの状態で、接着剤５は常温
放置、または加熱硬化され硬化させる。 Next, in the same state as shown in FIG. 2C, the adhesive 5 is left to stand at room temperature or is cured by heating.

Furthermore, the adhesive 5 is pressure-filled into the bonding plane portion 3 by pressing the concave portion 4 into a flat shape, so that the bonding plane clearance is uniformly filled and the strength of the adhesive can be made uniform.

A groove is provided to prevent the adhesive from extruding, and a liquid adhesive such as epoxy or acrylic is applied to the groove to join the two plates, and the groove is flattened by pressure to apply the adhesive to the bonding plane. The feature is that the adhesive is applied uniformly by applying pressure to the area, and the excess adhesive is stored in the grooves and does not protrude into the grooves that serve as the refrigerant flow path, preventing the flow of the refrigerant from being obstructed as in the case of conventional adhesives. There is no. Further, during long-term use, problems such as extruded and hardened adhesive flowing into the cooling system as foreign matter are avoided.
更に、接着剤の加圧充填により接着剤の充填む
らがなく、接着強度を均等化できるものである。 Furthermore, by pressure filling the adhesive, there is no uneven filling of the adhesive, and the adhesive strength can be made uniform.
