Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
The outdoor heat exchanger of the electric automobile comprises a left collecting pipe 11 and a right collecting pipe 12 which are arranged in parallel as shown in figures 1 and 2, a flat pipe 13 is connected between the left collecting pipe 11 and the right collecting pipe 12, and an electronic expansion valve 2 and an inlet and outlet assembly 4 are arranged on one side of the left collecting pipe 11. The electronic expansion valve 2 is connected to the left collecting pipe 11 through the connecting base 3 and communicated with the left collecting pipe 11. The outdoor heat exchanger of the electric automobile with the structure is used for a heat pump system of the electric automobile, and aims to realize condensation and evaporation of a refrigerant in the outdoor heat exchanger and meet the requirement of an air conditioner of the electric automobile.
In the invention, the connecting surface of the connecting seat 3 and the left collecting pipe 11 is an arc clamping surface, the electronic expansion valve 2 is fixedly connected on the connecting seat 3 through a screw, the connecting seat 3 can be welded or positioned on the left collecting pipe 11 through clamp connection, and the stable connection can be ensured through the arc clamping surface which is connected on the left collecting pipe in a fitting manner.
In the invention, in the evaporation process, the electronic expansion valve 2 is provided with a liquid inlet and a gas outlet. The liquid refrigerant flows in from the liquid inlet of the electronic expansion valve 2, is throttled and depressurized by the electronic expansion valve 2, enters the collecting pipe, flows into each flat pipe 13 after being uniformly distributed by a plurality of partition plates, and the evaporated gas refrigerant flows out of the condenser through the gas outlet of the electronic expansion valve 2. During the heat exchange process, the refrigerant absorbs heat through the gaps in the fins 4, so that the refrigerant is changed from liquid to gas.
In the invention, the sealing gaskets are arranged between the liquid inlet and the air outlet of the electronic expansion valve and the left collecting pipe so as to ensure good sealing effect.
In the invention, in the condensation process, the inlet and outlet components are provided with an air inlet and an liquid outlet, the refrigerant flows in the flat tubes 13, cooled air flows along the outsides of the flat tubes 13, and the refrigerant is condensed when meeting cold to release heat in the refrigerant, thereby changing the refrigerant from gas into liquid. The high-pressure high-temperature gas refrigerant conveyed from the compressor of the automobile air conditioning system enters the condenser from the air inlet, flows into each flat tube 13 through a plurality of partition plates in a uniformly distributed mode, and condensed liquid flows out of the condenser from the liquid outlet. In the process of refrigeration, hot air generated on the surface of the condenser flows out through gaps in the fins 3, heat in the refrigerant is released, and the refrigerant is changed from gas to liquid.
In the present invention, fins 4 are provided between adjacent flat tubes 13. As shown in fig. 3, the fin 4 has a rectangular structure as a whole, which is obliquely arranged between adjacent flat tubes. The fin 4 is provided with a plurality of windows 41, and the windows 41 are symmetrically arranged along the width direction of the fin 4 by taking the center line of the fin 4 as a symmetry axis. The window-opening angle range of the fin is 31-38 degrees, and the fin is a large-attack-angle window, so that the heat exchange efficiency can be greatly improved.
