Embodiment Construction
[0057] The present invention will be described in detail below with reference to the accompanying drawings.
[0058] refer to Figure 2 to Figure 7 , the microchannel heat exchanger of the first embodiment will be described.
[0059] The air conditioner in this embodiment includes: a compressor 10 for compressing refrigerant; a condensation heat exchanger 26 for condensing the refrigerant supplied by the compressor 10; an expansion mechanism 23 for cooling the refrigerant in the condensation heat exchanger. The condensed liquid refrigerant is expanded; the evaporative heat exchanger 20 expands the refrigerant expanded by the expansion mechanism 23 .
[0060] The expansion mechanism 23 can use various types such as an electronic expansion valve (eev), a Bi-flow valve, or a capillary tube.
[0061] The air conditioner may further include: a condensing fan 11 for making air flow to the condensing heat exchanger 26 ; and an evaporating fan 12 for making air flow to the evaporati...

A heat exchanger, which is formed into a micro-channel type, includes a first heat exchange module and a second heat exchange module configured with a plurality of flat tubes, including: a first path configured in the first heat exchange module. A part of the flat tubes makes the refrigerant flow in one direction; the second path is a part of the rest of the flat tubes arranged in the first heat exchange module, and makes the refrigerant supplied in the first path flow. It flows in the direction opposite to the first path; the third path is arranged in the remaining part of the plurality of flat tubes arranged in the first heat exchange module except the first path and the second path and in the second heat exchange module A part of the plurality of flat tubes arranged in the second path makes the refrigerant supplied in the second path flow in a direction opposite to that of the second path; the fourth path is arranged in the remaining part of the plurality of flat tubes arranged in the second heat exchange module , so that the refrigerant supplied in the third path flows in the direction opposite to the third path.
Description
technical field [0001] The present invention relates to a heat exchanger. Background technique [0002] Generally, a heat exchanger can be used as a condenser or an evaporator in a refrigeration cycle device including a compressor, a condenser, an expansion mechanism, and an evaporator. [0003] Also, the heat exchanger is installed in a vehicle, a refrigerator, etc., so that the refrigerant exchanges heat with air. [0004] According to the structure, the heat exchanger may be classified into a fin tube type heat exchanger, a microchannel type heat exchanger, and the like. [0005] The finned tube heat exchanger is made of copper material, and the microchannel heat exchanger is made of aluminum material. [0006] Micro-channel heat exchangers are more efficient than fin-tube heat exchangers because of the fine flow paths formed inside. [0007] The fin-tube heat exchanger is a method of welding fins and tubes, which is easy to manufacture, but the micro-channel heat exch...
