Heat exchange tube wound ribbon, heat exchanger and air conditioner

Abstract

The application provides a heat exchange tube wound ribbon, a heat exchanger and an air conditioner. The heat exchange tube wound ribbon is used for being wound outside a heat exchange flat tube (3),and comprises a wound ribbon body (1) and a plurality of groups of heat exchange fins arranged on the wound ribbon body (1); each group of heat exchange fins comprises at least two fin units (2); theadjacent groups of heat exchange fins are separately positioned on different heat exchange surfaces of the heat exchange flat tube (3); and the same groups of fin units (2) are arranged at intervals.According to the heat exchange tube wound ribbon, the condition that fin holes are blocked by water films under the conditions of low air pressure and high humidity can be effectively avoided, and theheat exchange effect of the heat exchanger is improved.

Description

technical field [0001] The application belongs to the technical field of air conditioning, and in particular relates to a heat exchange tube coil, a heat exchanger and an air conditioner. Background technique [0002] At present, most of the air-conditioning evaporators installed in passenger cars use insert heat exchangers and micro-channel heat exchangers. In the process of using the insert heat exchanger and the microchannel heat exchanger, many shortcomings that need to be overcome are exposed: under the same heat exchange capacity, the mass of the insert heat exchanger is relatively large, which increases the burden on the car body and affects the cruising range of the car. The improvement of the micro-channel heat exchanger has a negative impact; the heat transfer effect of the micro-channel heat exchanger is weaker than that of the insert heat exchanger, and in the working environment of high humidity and low flow rate on the air side, condensate accumulation and wate...

Problems solved by technology

In the process of using the insert heat exchanger and the microchannel heat exchanger, many shortcomings that need to be overcome are exposed: under the same heat exchange capacity, the mass of the insert heat exchanger is relatively large, which increases the burden on the car body and affects the cruising range of the car. The improvement of the micro-channel heat exchanger has a negative impact; the heat transfer effect of the micro-channel heat exchanger is weaker than that of the insert heat exchanger, and in the working environment of high humidity and low flow rate on the air side, condensate accumulation and water will appear on the surface of the micro-channel heat exchanger. When the membrane blocks the flow path on the air side

At present, the situation of the above two mainstream vehicle air-conditioning heat exchangers is not conducive to the promotion of vehicle energy-saving technology
