Flat heat exchange tube of heat exchanger and heat exchanger of flat heat exchange tube

Abstract

The invention discloses a flat heat exchange tube of a heat exchanger and the heat exchanger of the flat heat exchange tube, and relates to a flat tube structure of a fine channel heat exchanger. The scheme is a divisional application of the 'flat tube structure of 200910070901.7 heat exchanger and the heat exchanger of the flat tube structure', wherein a partition plate is arranged between adjacent channels; an isosceles area section of a triangular channel is formed between the adjacent partition plates; the two adjacent partition plates are combined with a first lateral wall or a second lateral wall of the flat heat exchange tube to form the triangular channel; two adjacent triangular channels are symmetrical and form a structure of a parallelogram; the heat exchanger is provided with the flat tube structure; a blind area section is composed of preset quantity of open windows which are uniformly distributed on a straight area section; the structure of each open window is the same and the window is arranged towards the air flow direction to form a structure in which the air tipsily flows downwards along the air flow direction, and the open windows can enable the air to tipsily flow downwards along the open window in the air flow direction. According to the scheme, the heat transfer efficiency of the heat exchanger is effectively improved by improving a flat tube channel, and the condensate water is smoothly discharged and not easily frozen by improving a wing band structure, so as to effectively improve the heat exchange efficiency.

Description

technical field [0001] The invention belongs to the field of air conditioning, relates to a flat tube structure of a fine channel heat exchanger, and is suitable for evaporators of household air conditioners, commercial air conditioners and central air conditioners. This case is a divisional application of "200910070901.7 Flat tube structure of heat exchanger and its heat exchanger". Background technique [0002] The engineering background of microscale heat transfer problems comes from the cooling of high-density electronic devices in the 1980s and the flow and heat transfer problems in microelectromechanical systems that emerged in the 1990s. Its characteristic is that when the scales of space and time are miniaturized, many physical phenomena appear that are different from conventional scales. Micro-channel radiator is a technology that the industry has been researching and using. It is reported that as early as the 1980s, scientists proposed the concept of "micro-channe...

AI Technical Summary

Problems solved by technology

[0006] In the flat tube structure of the prior art, the flat tubes all have passages for dispersing and flowing the refrigerant, and the cross-sections of the passages are rectangular, so eddy currents are easily generated at four right angles (especially when used as an evaporator). ), so it is unfavorable to heat exchange; some channels have a circular or elliptical cross-section. The problem is that such channels cannot be arranged in many flat tubes, and there are few channels, which restricts the further improvement of the heat exchange capacity of the heat exchanger.
