Description
Technical field：
The utility model is related to a kind of evaporators, are especially a kind of automobile air conditioning system double layer evaporation device.
Background technology：
Air conditioning for automobiles industry is lacing film generally using pipe type evaporator in automobile air conditioning system evaporator applications
Tube-expanding type structure, i.e. coolant channel are mostly copper pipe or aluminum pipe, after putting on a certain number of fins, with the side of machinery or hydraulic pressure
The characteristics of method is increased the diameter of pipe by the head that rises, is in close contact pipe and fin, and heat transfer is realized with this, the structure be it is simple,
Easy processing, but heat exchange efficiency is low, and in the case where needing to reach similary heat exchange amount, required heat exchange area is larger, in bus sky
Evaporator applications are adjusted in application, the refrigerating capacity that should be needed for big bus with air conditioners is larger, generally all in more than 12000w, using pipe type
The evaporator volume of structure is larger, and weight is also heavier, so cost is higher, the energy consumption come to automobile belt is also big.In addition, section of jurisdiction
The evaporator of formula structure with the increase of usage time, manages the stress meeting of the contact side with fin at evaporator core tensioner
Reduce, can become to loosening, cause hydraulic performance decline.It is particularly used on automobile, during air-conditioning work, automobile is substantially at driving process
In, evaporator can be constantly in motion state, so its stress decrease speed can be accelerated.Therefore there are heat exchanger efficiency is low, body
The problem of product is big, Long-Term Properties decline.Authorization Notice No. is number CN203163351U, and the Granted publication date is 2013 8
The Chinese patent of months 28 days discloses a kind of automobile air conditioning system soldering formula evaporator, including evaporator core, evaporator core with
One evaporator passes in and out pipe assembly soldering connection, and one end of evaporator disengaging pipe assembly is equipped with expansion valve, two evaporator cores
Pipe assembly is passed in and out by expansion valve to be connected as one.
Utility model content：
Technical problem to be solved in the utility model is to provide a kind of reasonable design, simple in structure, at low cost, heat exchange
Efficient automobile air conditioning system double layer evaporation device.
The technical solution of the utility model is to provide a kind of automobile air conditioning system double layer evaporation device, including two bilayers
Micro-channel evaporator core, further includes casing, and two double-deck micro-channel evaporator core one end connect to form evaporation by casing
The afflux tube end of one end of device unit, double-deck micro-channel evaporator core and casing connection is openend, openend and casing
It is welded and fixed, inlet tube is also associated on one of casing, inlet tube is connected with casing, and outlet is connected on another casing
Pipe, air outlet pipe connect setting with casing.
Using compared with prior art, the utility model has the following advantages after more than structure：Two are connected using casing
A bilayer micro-channel evaporator core so that reasonable design, simple in structure, at low cost, heat exchange efficiency height.
Preferably, the double-deck micro-channel evaporator core other end is equipped with the installation branch for being used for being mounted on bus car body
Frame.Facilitate and fix on the car body.
Preferably, the header cross section of double-deck micro-channel evaporator core is D types.
Preferably, including multiple evaporator units, multiple evaporator units are arranged in parallel.
Further, the openend of header is equipped with partition, has through-hole on partition.

Fig. 1 is the structure diagram of the utility model embodiment.
Fig. 2 is the structure diagram of the utility model embodiment middle sleeve.
Specific embodiment：
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figs. 1-2, a kind of automobile air conditioning system double layer evaporation device including two double-deck micro-channel evaporator cores 1, is gone back
Including casing 2, two double-deck 1 one end of micro-channel evaporator core connect to form evaporator unit by casing, double-deck microchannel
11 end of header of one end that evaporator core 1 is connect with casing 2 is openend, and openend and the casing 2 of header 11 weld
Fixation is connect, 11 cross section of header is D types, and the openend of header is equipped with partition 12, has through-hole on partition 12.It is corresponding
, the cross-section adaptation of the cross-sectional shape of casing and double-deck header, preferably, casing 2 is set on header to carry out again
It is welded and fixed.Inlet tube 3 is also associated on one of casing 2, inlet tube 3 is connected with casing 2, is connected on another casing 2
There is air outlet pipe 4, air outlet pipe 4 connects setting with casing 2.For convenience of installation, double-deck 1 other end of micro-channel evaporator core, which is equipped with, to be used
In the mounting bracket 5 on bus car body.In addition, to improve efficiency, the utility model can include multiple evaporator lists
Member, multiple evaporator units are arranged in parallel.
Pass through above structure so that reasonable design, simple in structure, at low cost, heat exchange efficiency height.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.Every equivalent structure or equivalent flow shift done using the utility model specification and accompanying drawing content is included in this
Within the scope of patent protection of utility model.
