Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as Figure 1 to Figure 6 The shown heat exchanger includes: a shell 1, generally the shell 1 is a cylindrical structure, the axis of the cylindrical structure is arranged horizontally, and there is an air inlet at the upper end of the peripheral side of the cylindrical structure, and a liquid outlet;

[0031] The partition 2 is arranged inside the housing 1, and divides the interior of the housing 1 into a cooling area and a supercooling area. Preferably, the partition 2 is also arranged horizontally or at a certain angle with the horizontal plane, so that A cooling area is formed abo...

Abstract

The invention provides a heat exchanger with a good supercooling effect and an air conditioning unit. The heat exchanger comprises a shell, a partition plate, a plurality of baffle plates and a plurality of heat exchange pipes, wherein the baffle plates are arranged in a supercooling area at intervals to form a baffle flow channel, the baffle plates are in a curved surface shape, and an included angle is formed between the protruding direction of the curved surface shape and the flow direction of a refrigerant in the supercooling area; and the heat exchange pipes are arranged in the supercooling area in parallel, and each heat exchange pipe penetrates through all the baffle plates. According to the heat exchanger with the good supercooling effect and the air conditioning unit, the baffle plates in the curved surface shape are arranged, so that the problem of a flowing dead zone caused by a flat plate type baffle plate in the prior art is effectively solved, the turbulent flow effect onthe liquid refrigerant is increased, the supercooling effect is improved, the utilization degree of the supercooling area is improved, and therefore the purpose of improving the supercooling effect of the heat exchanger is achieved.

Description

technical field [0001] The invention relates to the technical field of air treatment equipment, in particular to a heat exchanger and an air conditioning unit with high supercooling effect. Background technique [0002] In the horizontal shell-and-tube condenser, from the perspective of the heat exchange area, it can be divided into two parts: the upper cooling area and the lower subcooling area. In order to improve the heat exchange efficiency of the condenser, in the prior art, the subcooling The method of adding flat-shaped baffles in the area, but the flat-shaped baffles have a large flow dead zone during the baffle process, resulting in low air conditioning utilization in the supercooled area, uneven distribution of subcooling, and The problem that the supercooling effect is not obvious. Contents of the invention [0003] In order to solve the technical problem in the prior art that flat baffles have flow dead zones that affect the supercooling effect, a heat exchang...
