no. 1 approach

[0065] An embodiment according to the present invention is an air conditioner 1 that has a refrigerant circuit 10 and switches between a cooling operation and a heating operation. The air conditioner 1 has an indoor unit 20 installed indoors and an outdoor unit 30 installed outdoors. The indoor unit 20 and the outdoor unit 30 are connected to each other through two connecting pipes 11 and 12 to form a closed refrigerant circuit 10 . Refrigerant circuit 10 is filled with refrigerant. A vapor compression refrigeration cycle is performed by refrigerant circulation in the refrigerant circuit 10 .

[0066] 〈Indoor unit〉

[0067] The indoor unit 20 has an indoor heat exchanger 21 , an indoor fan 22 and an indoor expansion valve 23 . The indoor heat exchanger 21 is constituted by, for example, a transverse-fin fin-and-tube heat exchanger. In the indoor heat exchanger 21 , the refrigerant flowing inside the heat transfer tubes exchanges heat with the air sent by the indoor fan 22 ...

Abstract

The present invention provides a coolant pipe installation structure which can reliably retain a coolant pipe and which can sufficiently decrease the thermal resistance between a coolant pipe and a heat-transmitting member. A heat-transmitting member (70) having a vertical groove part (72) into which a coolant pipe (15) fits, and which thermally contacts with a component to be cooled (63), is provided. An elastic member (80) formed in a long plate shape which extends in the extension direction of the coolant pipe (15), and having an opposing part (82) opposite the coolant pipe (15), is provided. A pushing structure (90) which pushes the elastic member (80) to the heat-transfer member (70) side is provided.

Description

technical field [0001] The present invention relates to an installation structure of a refrigerant pipe in a cooling structure in which a component to be cooled is cooled by refrigerant passing through the refrigerant pipe. Background technique [0002] Conventionally, cooling structures in which a component to be cooled is cooled by a refrigerant passing through a refrigerant pipe are known. For example, Patent Document 1 discloses a cooling structure in which electric components in an air conditioner are used as cooled components. [0003] Specifically, the cooling structure in Patent Document 1 has a heat transfer member on which a groove having an arc-shaped bottom surface is formed, and a support member for directing the refrigerant pipe toward the heat transfer member. side crimped. The supporting member is constituted by, for example, an elastic clip (clip) whose cross section is U-shaped with one side of the refrigerant pipe open. The refrigerant pipe is inserted ...
