Example Embodiment

[0020] Referring to Figures 1 and 2, the design concept of the present invention is to improve the refrigerant flow, so as to increase the refrigerant flow rate in the U-shaped tube 12 of the external heat exchanger, thereby improving the heat exchange effect.

[0021] The refrigerant enters from the inlet pipe 13, and is divided into 4 channels to form 4 inlet pipes 13-1, 13-2, 13-3, and 13-4, and enter the U-shaped copper pipe 11 of the inner heat exchanger. After the same number of U-shaped copper tubes 11 of the inner-row heat exchanger, for example, 3 U-shaped tubes, enter the U-shaped tube 12 of the outer-row heat exchanger through the jumper pipe 14, and the U-shaped tube 11 of the inner-row heat exchanger is merged at the confluence. The two channels of refrigerant are divided into the outlet ends of the same number of U-shaped tubes, so that the distances flowed by each channel are equal, and the heat exchange is balanced. Each refrigerant entering the U-shaped tube 1...

Abstract

The invention provides a heat exchanger for an outdoor machine of an air conditioner and an outdoor machine using the heat exchanger, ,which can enhance the flow speed of the refrigerants so as to enhance the heat exchanging capacity on the existing basis. The technical scheme of the invention is that the refrigerant diffluence is applied to an inlet tube in even ways and the inlet tube is connected with an internal drainage U-shaped copper tube; and every two ways of refrigerants are converged into one way of refrigerant after each way of refrigerant flows through various pipelines of the internal drainage U-shaped copper tube and one way of refrigerant enters an external drainage U-shaped copper tube; each way of refrigerant entering the external drainage U-shaped copper tube is converged into one way by a confluence device after flowing through various pipelines of the external drainage U-shaped pipeline so as to enter a subcooling region at the lower end of the heat exchanger. When the refrigerant diffluence is carried out, two ways of refrigerants are converged into one way of refrigerant. When the confluence is conducted, the flow speed of the refrigerant is enhanced, the heat transfer rate in unitary time is enhanced and the energy efficiency ratio of the refrigeration is enhanced too, and the heating effect is assured when the heating is carried out, due to the increase of the flow rate.

Description

technical field [0001] The invention relates to an outdoor heat exchanger for an air conditioner, in particular to an outdoor unit heat exchanger of a heating and cooling heat pump type air conditioner used in an air conditioner, and is an optimization and improvement of the heat exchange capacity of the existing outdoor heat exchanger. Background technique [0002] The existing on-hook outdoor heat exchangers generally use double-row heat exchangers for high-efficiency machines, which are divided into inner-row heat exchangers and outer-row heat exchangers. The flow direction adopts the design of reverse flow or mixed flow. The reverse flow is the U-shaped tube of the inner row heat exchanger and then the U-shaped tube of the outer row heat exchanger. The reverse direction refers to the flow from the inside to the outside, which is opposite to the direction of the wind. Mixed direction is the alternating flow of inside and outside. The heat exchanger process of multiple U-...
