Problems solved by technology

[0004] However, a problem with the above-mentioned conventional fins is that when the air flows through the fins to exchange heat with the refrigerant tubes, air turbulence sufficient to promote heat dissipation cannot be established on the surface of the fins, so there is still heat generated by the air. Boundary layer, so that the heat exchange efficiency is not high
However, such compounds may have damaging effects on the ozone layer in the atmosphere because they contain chlorine elements

Embodiment Construction

[0049] Referring now to the accompanying drawings, preferred embodiments of the present invention will be described.

[0050] figure 1 It is a perspective view of a common household air conditioner. This type of air conditioner has a user side unit A (indoor unit) installed indoors and a heat source side unit B (outdoor unit) installed outdoors, and the indoor unit A and the outdoor unit B communicate with each other through a refrigerant pipe 300 . figure 2 yes means figure 1 A schematic diagram of the refrigerant circuit of the refrigeration circuit of the air conditioner shown.

[0051] Such as figure 2 As shown, the refrigerant circuit includes a compressor 1 composed of a motor part and a motor-driven compression part; a muffler for suppressing the vibration and noise caused by the intermittent discharge of the refrigerant from the compressor 1; switching the refrigerant between Four-way switching valve for flow direction during cooling / heating operation 3; heat exc...

Abstract

In a heat exchanger comprising a number of multilayered fins, and a refrigerant pipe arranged in the meandering form in the fins, and an air conditioner having the heat exchanger, each of the fins has a corrugated portion formed in an air-flow direction thereon, which has at least two wavelike portions for producing a turbulent flow of air having such strength that a temperature boundary layer of the air is broken, but resistance against to the air flow is not excessively high. Each wavelike portion may be designed to have a triangular section or a trapezoidal section, and a flat portion may be disposed between the wavelike portions.

Description

technical field [0001] The present invention relates to a heat exchanger composed of a large number of fins and refrigerant tubes and an air conditioner having the heat exchanger, wherein the fins are arranged in a multi-layer structure, and the refrigerant tubes are inserted into the multi-layer fins so that Extend into a zigzag form. Background technique [0002] In a conventional heat pump air conditioner, during cooling operation, the refrigerant flows through the compressor, the heat source side (outdoor side) heat exchanger, the four-way switching valve, the flow control valve (expansion valve), the user side (indoor side) The sequential circuit of the heat exchanger and the four-way switching valve, while in the heating process, the refrigerant is in the opposite direction of the cooling process. The heat exchanger on the heat source side acts as an evaporator during heating and as a condenser during cooling. [0003] In order to increase the heat exchange efficienc...
