Example Embodiment

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] see figure 1 and figure 2 , in order to propose a new type of windowed fin with greatly improved heat transfer capacity and small resistance increase, in order to obtain higher heat transfer efficiency. A specific embodiment of the present invention is that the fins have two rows, and each row of fins has several copper tube holes 1, and the upper and lower sides of each copper tube hole 1 are symmetrically provided with the same window unit 2, each of which The window unit 2 is arranged left and right symmetrically by the same window group 21 , and each window group 21 is composed of the same short window group 211 and the middle long window group 212 arranged at intervals up and down on the outer side. The short window set 211 and the long window set 212 have a plurality of windows, and each window is inclined at the same angle. The incli...

Abstract

The invention provides a high-efficiency air-condition heat exchanger fin and a heat exchanger, which can solve the problem of low heat exchange efficiency and the like existing in the prior art. The invention has the technical scheme that the high-efficiency air-condition heat exchanger fin is provided with at least one column of fins; each column of fins is provided with a plurality of copper pipe holes; the upper side and the lower side of each copper pipe hole are symmetrically provided with identical window slice units; each window slice unit is formed by symmetrically arranging identical window slice groups left and right; each window slice group comprises the identical short window slice groups which are arranged up and down at intervals at the outer side and a middle long window slice group; the short window slice groups and the long window slice group are provided with a plurality of window slices; and each window slice is obliquely arranged at the same angle. The heat exchange ability and the overall energy efficiency ratio can be improved by adopting heat exchanger of the fin, and the cost is reduced to a greater degree; simultaneously, the frosting problem of the external heat exchanger of an air-condition chamber is considered, so the fin structure is more convenient for frost removal.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration engineering, and in particular relates to a high-efficiency heat exchanger fin in an air conditioner. Background technique [0002] The heat exchanger in the air conditioner is mainly composed of several fins and several copper tubes expanded on the fins. Therefore, the fin structure design of the heat exchanger on the air conditioner is very important, it will directly affect the efficiency of convective heat transfer, thereby affecting the level of heat transfer. There are various structural forms of air-conditioning heat exchanger fins, from the initial flat fins and corrugated fins to the later development of louver fins and slotted fins. However, there are still imperfections in the existing fin structure, mainly because the design of the contact area between the air intake and the fins is still insufficient, and the contact area with the air intake is small, which...
