Title:
COAXIAL TUBE, AUTOMOBILE AIR CONDITIONING SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/024674
Kind Code:
A1
Abstract:
The present invention provides a coaxial tube, an automobile air conditioning system, and a vehicle. The coaxial tube comprises: an outer cylinder body, a middle cylinder body, and a top cap. The middle cylinder body is located in the outer cylinder body. The top cap is located on one end of the outer cylinder body and the middle cylinder body. A first heat exchange cavity is defined between the outer cylinder body and the middle cylinder body. At least two first partition plates are provided between the outer cylinder body and the middle cylinder body. The at least two first partition plates divide the first heat exchange cavity into at least two first sub-exchange cavities, and the at least two first sub-exchange cavities are communicated at the bottom. At least one first inlet and at least one first outlet are formed on the top cap. The first inlet is communicated with one of the first sub-exchange cavities, and the first outlet is communicated with the other first sub-exchange cavity. The first inlet is configured to be communicated with an outlet of an evaporator, and the first outlet is configured to be communicated with an inlet of a compressor. The coaxial tube, the automobile air conditioning system, and the vehicle provided in the present invention are used for solving the problem that the efficiency of heat exchange between an inner tube and an outer tube of the coaxial tube is not high so that an expected effect is not achieved.
