Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0022] Such as Figure 1~3 As shown, the present invention provides a multi-refrigerant channel heat exchanger, including:
[0023] Refrigerant tube group, which includes a plurality of refrigerant tubes 1 arranged at intervals from top to bottom with the same size and parallel to each other. It is a hollow tubular structure arranged horizontally, and the two ends of the plurality of refrigerant tubes 1 are sequentially connected. The connected ends of the two adjacent refrigerant pipes 1 are respectively screwed into the two ends of the semicircular connecting pipe 2, and one end of the uppermost refrigerant pipe 1 is a free end and is provided with a refrigerant inlet 11 One end of the lowermost one of the refrigerant pipes 1 is a free end and is provided with a refrigeran...

The invention discloses a heat exchanger of multiple refrigerating fluid channels. The heat exchanger comprises a refrigerating fluid pipe unit, wherein the refrigerating fluid pipe unit includes a plurality of refrigerating fluid pipes arranged at intervals from top to bottom; both ends of the refrigerating fluid pipes are orderly interconnected end to end; the refrigerating fluid pipes at the uppermost and bottommost parts are respectively provided with a refrigerating fluid inlet and a refrigerating fluid outlet, so that the refrigerating fluid pipe unit is interconnected with a plurality of connecting pipes, a flow path of the refrigerating fluid in the refrigerating fluid pipe unit is formed; the inner part of the refrigerating fluid pipe is partitioned by a plurality of vanes along radial direction to form mutually independent fan-shaped channels; a fin group, of which upper end is provided with a vibrator, and a plurality of separated annular grooves are arranged on the first side surface of the fin as for any one groove. The heat exchanger can effectively distribute the refrigerating fluid through adding the number of the refrigerating fluid channel; the refrigerating fluid in every refrigerating fluid channel is contacted with the pipe wall of the refrigerating fluid pipe; thus the utilization rate of the refrigerating fluid is improved, water on the surface of the fin is collected, and the heat exchanging efficiency is improved.
Description
technical field [0001] The invention relates to a heat exchanger, in particular to a heat exchanger with multiple refrigerant channels. Background technique [0002] A heat exchanger is a device that exchanges heat between an internal refrigerant and an external fluid. A heat exchanger can be used as a condenser or an evaporator in a refrigerant cycle formed by a compressor, a condenser, an expansion device and an evaporator. Heat exchangers can be divided into finned tube heat exchangers and microchannel tube heat exchangers. A finned heat exchanger includes a plurality of fins and a plurality of cylindrical or nearly cylindrical tubes passing through the plurality of fins. The finned heat exchanger exchanges heat between the external fluid and the refrigerant flowing in the tubes, and the fins increase the heat exchange area between the external fluid and the refrigerant flowing in the tubes. [0003] However, the traditional heat exchanger has the following limitations...
