Description

High-efficiency evaporator

Technical field

The utility model relates to a kind of automotive air-conditioning system components, and in particular to a kind of high-efficiency evaporator.

Background technique

Evaporator in air conditioning for automobiles is the cold and hot direct component of conduction, general evaporator include mounting plate, fin and Cold conduit, cold conduit are connect with compressor, from the gaseous refrigerant of the low-temp low-pressure of compression sucking evaporator exit, refrigeration The gaseous state that agent is compressed into high temperature and pressure is arranged to condenser, and evaporator is just to provide cold air output block.Existing evaporator heat is handed over It is lower to change efficiency, can just go out cold air after air conditioning for automobiles starting after a period of time, refrigeration is slow, and more oil is lost in this in the process Consumption and electric energy, so that automobile fuel consumption increases.

Summary of the invention

To solve the above problems, the purpose of this utility model is to provide a kind of heat exchanger effectiveness height, structure are reliably high Imitate evaporator.

To achieve the above object, the utility model provides following technical solution: a kind of high-efficiency evaporator, including evaporator Ontology is equipped with fin and cold pipe in the evaporator body, and the cold pipe is interspersed in the fin, the cold pipe it Between be connected to by bend pipe, be additionally provided with water inlet pipe and outlet pipe on the evaporator body, the cold pipe outer wall be equipped with according to The V-groove of secondary arrangement, the fin are equipped with jack corresponding with the V-groove, which is plugged in the V-groove, More than two rectangular slices are equipped on the fin, the rectangular slice bend relief in the side of the fin, Be covered with circular hole on the rectangular slice, on the location mid-shaft of the cold pipe be equipped with inserted link, inserted link by connecting rod with it is described Cold inside pipe wall connection, formed between the inserted link and cold inside pipe wall annular circulation road.

Through hole is additionally provided on the connecting rod.

This structure of the utility model, when the gaseous refrigerant of high temperature and pressure leads to supercooling tube, the location mid-shaft of cold pipe Temperature is lowest temperature and most concentrates, after which is filled by inserted link, so that circulation of the gaseous refrigerant by annular Road passes through, so that low temperature is faster conducted to cold pipe outer wall, the area of heat exchange is can be improved in the V-groove in cold pipe outer wall, simultaneously The efficiency that heat exchange is further improved after rectangular slice bend relief on fin, just realize in this way heat exchanger effectiveness it is high, The reliable effect of structure.

The utility model is further described with reference to the accompanying drawings and detailed description.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；

Fig. 2 is the cooperation figure of fin and cold pipe in specific embodiment of the present invention.

Specific embodiment

As shown in Figure 1 and Figure 2, present embodiment discloses a kind of high-efficiency evaporator, including evaporator body 1, evaporator bodies Fin 2 and cold pipe 3 are equipped in 1, cold pipe 3 is interspersed in fin 2, is connected between cold pipe 3 by bend pipe 4, on evaporator body 1 also Equipped with water inlet pipe 5 and outlet pipe 6, cold 3 outer wall of pipe is equipped with the V-groove 7 being arranged successively, and fin 2 is equipped with opposite with the V-groove 7 The jack answered, the jack are plugged in V-groove 7, set on fin 2 there are two rectangular slice 21, it is rectangular slice 21 bending it is convex Two side directions in fin 2 are played, are covered with circular hole (not showing in circular hole figure) on rectangular slice 21, in the location mid-shaft of cold pipe 3 It is equipped with inserted link 8, inserted link 8 is connect by connecting rod 9 with cold 3 inner wall of pipe, and the stream of annular is formed between 3 inner wall of the inserted link 8 and cold pipe Channel 10.

Through hole 91 is additionally provided on connecting rod 9.The passability of the gaseous refrigerant of high temperature and pressure can be made more preferable in this way, further Improve heat exchanger effectiveness.

This structure of the utility model, when the gaseous refrigerant of high temperature and pressure leads to supercooling tube 3, the location mid-shaft of cold pipe 3 Temperature be lowest temperature and most concentrate, the location mid-shaft by inserted link 8 fill after so that gaseous refrigerant by annular stream Channel 10 is passed through, so that low temperature is faster conducted to cold 3 outer wall of pipe, the face of heat exchange is can be improved in the V-groove 7 on cold 3 outer wall of pipe Product, while the efficiency of heat exchange is further improved after 21 bend relief of rectangular slice on fin 2, hot friendship is just realized in this way Change high-efficient, the reliable effect of structure.
