Embodiment Construction

[0031] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] In this article, if there is no special explanation, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.

[0033] a heat exchanger such as figure 1 As shown, the heat exchanger includes an upper header 8 and a lower header 9 and heat exchange tubes arranged between the upper and lower headers 8 and 9 . Fins 11 are arranged between the heat exchange tubes. The heat exchanger can be widely used such as automobile heat exchanger, air conditioner heat exchanger and so on.

[0034] Such as figure 2 As shown, the heat exchange tubes are flat heat exchange tubes, including flat tubes 1 and fins 7, the flat tubes 1 include tube walls 3 and side walls 12 parallel to each other, and the side walls 12 connect parallel tube walls 2, the fluid channel 2 is formed between the side wall 12 and the parallel tube...

Abstract

The invention provides a heat exchanger. The heat exchanger comprises an upper header, a lower header and heat exchange pipes arranged between the two headers; the heat exchange pipes are flat heat exchange pipes, fins are arranged in the flat pipes and comprise inclined parts, the inclined parts divide a fluid channel into a plurality of small channels, and the vertex angles B of first isosceles triangles in the flat heat exchange pipes become smaller when the distance to an inlet pipe gets larger. According to the invention, the vertex angles B change along with the distance to the inlet pipe, fluid flows to the heat exchange pipes small in flow resistance and larger in distance to the inlet pipe so as to be distributed uniformly in the heat exchange pipes, and therefore the heat exchange efficiency is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a shell-and-tube heat exchanger. Background technique [0002] Flat tubes have been widely used in recent years in automotive air conditioning units and in residential or commercial air conditioning heat exchangers. This kind of flat tube is provided with multiple small channels inside, and when in use, the heat exchange fluid flows through the multiple channels in the flat tube. Because the heat exchange area of ​​the flat tube is large, the heat exchange effect can be greatly improved. [0003] In the prior art, there is a problem of uneven flow distribution caused by the distance between the heat exchange tube and the inlet tube. For example, the closer the distance to the inlet tube, the more fluid flow in the heat exchange tube; Fluid flow is less. In the prior art, the flow distribution or pressure distribution components are installed in the header to make the flow distribution in th...
