Abstract

The invention provides a heat exchanger. The heat exchanger includes a casing (3) and at least two mutually independent refrigerant flow paths arranged in the casing (3), the refrigerant flow paths include a first refrigerant flow path and a second refrigerant flow path, and the first refrigerant flow path The path includes a plurality of first heat exchange tubes (1), the second refrigerant flow path includes a plurality of second heat exchange tubes (2), the first heat exchange tubes (1) and the second heat exchange tubes (2) (3) Inner cross mixed arrangement. According to the heat exchanger of the present invention, the problem that the heat exchange efficiency of the heat exchanger in the prior art cannot be effectively utilized can be solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat exchanger. Background technique [0002] like figure 1 As shown, the dual-channel dry heat exchanger currently on the market is arranged separately from the refrigerant side channel 1 and the channel 2, wherein the channel 1 includes the inlet pipe 3 and the outlet pipe 4, and the channel 2 includes Inlet pipe 5 and outlet pipe 6. At full load, flow path 1 and flow path 2 are opened at the same time, and at partial load, flow path 1 is opened and flow path 2 is closed, or flow path 2 is opened and flow path 1 is closed. The heat exchanger also includes a water flow path, which is an integral flow path, and performs heat exchange with the flow path 1 and the flow path 2. [0003] The obvious defect of the current product is that at part load, or 25% or 75% load, the refrigerant can only circulate on one side of the heat exchanger, while the other flow path is no...
