Abstract

The utility model relates to an automobile air conditioner evaporator, in particular to a novel energy-saving automobile air conditioner evaporator, which comprises an evaporator core body, a refrigerant inlet and outlet connection end, an expansion valve and a liquid inlet and outlet pipe assembly, wherein the refrigerant inlet and outlet connection end comprises a refrigerant inlet end and a refrigerant outlet end; the refrigerant inlet end and the refrigerant outlet end are respectively formed by an inner pipe and an outer pipe; the inner pipe is positioned in the outer pipe; the evaporator core body is connected to one end of the outer pipe; the expansion valve is connected to the other end of the outer pipe; the front end of the inner pipe is communicated with a collecting pipe on the evaporator core body; the front outer wall of the inner pipe is fixedly and hermetically connected with the inner wall of the outer pipe; and the diameter of the back outer wall of the inner pipe is smaller than that of the front outer wall of the inner pipe. The utility model has the advantages of simple structure and convenient manufacture, and prolongs the service life of the refrigerant inlet and outlet connection end.

Description

The novel energy-conserving automobile air-conditioning evaporator

Technical field

The utility model relates to a kind of automobile air-conditioning evaporator, and particularly a kind of novel energy-conserving automobile air-conditioning evaporator belongs to the manufacturing field of automobile air-conditioning evaporator.

Background technology

In the prior art, cold-producing medium turnover link structure is single on the automobile air-conditioning evaporator, service life is short, cold-producing medium turnover link simultaneously as with the circulation duct of expansion valve link and cold-producing medium, and atomized refrigerant liquid enters evaporimeter, and the cold-producing medium boiling point that enters evaporimeter is far below temperature in the evaporimeter, so refrigerant liquid flashes to gas, heat in evaporation process around a large amount of the absorption, then the refrigerant vapour of low-temp low-pressure enters compressor by refrigerant outlet end then again, then the refrigerant inlet end and then the refrigerant outlet end because the washing away and the variation of refrigerant condition of cold-producing medium, and, cause cold-producing medium to leak because cold-producing medium turnover link adopts single circulation duct to cause cold-producing medium turnover link and being connected with the useful life growth of expansion valve to be lost efficacy.

The utility model content

The purpose of this utility model is exactly the weak point in the background technology, provide a kind of simple in structure, easily manufactured, as the link that is connected with expansion valve, interior pipe is as the novel energy-conserving automobile air-conditioning evaporator of the circulation duct of cold-producing medium with outer tube in employing.

For achieving the above object, the utility model adopts following technical scheme: the novel energy-conserving automobile air-conditioning evaporator, comprise evaporator core, cold-producing medium turnover link, expansion valve, liquid in-out pipe assembly, be provided with expansion valve between cold-producing medium turnover link and the liquid in-out pipe assembly, and cold-producing medium turnover link is connected with expansion valve respectively with liquid in-out pipe assembly, described cold-producing medium turnover link comprises refrigerant inlet end and refrigerant outlet end, refrigerant inlet end and refrigerant outlet end are made of interior pipe and outer tube respectively, interior pipe is positioned at outer tube, outer tube one end is connected with evaporator core, the other end is connected with expansion valve, in the pipe front end be communicated with header on the evaporator core and the inside pipe wall of the pipe outer wall of interior pipe front end and outer tube for being sealedly and fixedly connected, interior pipe rear end pipe outer diameter is less than interior pipe front end outer diameter.

The utility model is compared with background technology, have simple in structure, easily manufactured, the service life of having improved cold-producing medium turnover link.
