Here there is the one side of boss portion 32 to be defined as the front of installing plate 3 installing plate 3, will with change
The one side that hot device is in contact is defined as the reverse side of installing plate 3.One is further opened with the reverse side of installing plate 3
Link slot 31, link slot 31 connection fourth hole 34 and valve element accommodating chamber 33.
Multiple is also provided with the reverse side of installing plate 3 be raised in the back side certain altitude of installing plate 3
Positioning boss 37, the positioning and peace of plate 3 and heat exchanger 10 can be easily installed by positioning boss 37
Dress.
As shown in figure 4, end plate 6 includes being located at first apertures 63 at four angles, the second aperture 62, the
Three apertures 61 and the 4th aperture 64, wherein the outer circumferential side in the 4th aperture 64 is also formed with one and protrudes from
The hollow lug boss 65 of the plate plane certain altitude of end plate 6, the internal diameter of lug boss 65 is less than or equal to
The internal diameter in the 4th aperture, lug boss 65 can be the punch structure formed by punch process.
The location hole 66 corresponding with positioning boss 37 can also be set on end plate 6, when mounted,
Installed by the cooperation of positioning boss 37 and location hole 66, can quickly position heat exchanger and installation
Plate, is easily installed, it is also possible to improve the installation accuracy and yields of heat-exchange device.
On heat exchangers, the first aperture 63 is corresponding with first through hole 353, the second aperture 62 and
Two through holes 352 are corresponding, and the 3rd aperture 61 is corresponding with third through-hole 351, the 4th aperture 64 with
Valve element accommodating chamber 33 is corresponding, and the internal diameter of valve element accommodating chamber 33 is more than or equal to the 4th aperture 64
Internal diameter, a part for core assembly 22 can be made to stretch into lug boss 65 through valve element accommodating chamber 33
In.And lug boss 65 protrudes from the direction of the plate plane of end plate 6 and boss portion 32 protrudes from installing plate
3 is positive in opposite direction.
The direction that certain lug boss 65 protrudes from the plate plane of end plate 6 can also protrude from boss portion 32
The positive direction of installing plate 3 is identical, and now, the height of lug boss 65 should be less than the depth of link slot 31
Degree.On the one hand the set-up mode of the lug boss 65 of the present embodiment can reduce the thickness of installing plate 3, separately
On the one hand the distance between outlet and heat exchanger 10 of core assembly 22 can further be reduced, from
And improve the heat exchange property of heat exchanger.
As shown in Figure 6 and Figure 7, core assembly 22 includes valve seat 220, and valve seat 220 includes first
225 and second 221, the outer wall of first 225 is provided with corresponding with hickey portion 321 outer
Screw thread, first 225 can seal fixation by the first sealing ring 226 and screw thread with boss portion 32,
Second 221 a part of can be tightly connected by sealing ring 223 with lug boss 65.Second
221 are provided with valve element intake channel 222 and cartridge outlet passage 224, in valve element intake channel 222
Throttle orifice is provided with and cartridge outlet passage 224 between, throttle orifice can connect valve element intake channel 222
With cartridge outlet passage 224.Also, the external diameter of second 221 is less than the internal diameter of valve element accommodating chamber 33,
The import of valve element intake channel 222 can be multiple, so be easy to refrigerant from valve element accommodating chamber 33
Flow into valve element intake channel 222.
The lower end of second 221 is stretched into lug boss 65, and is sealed by setting the second sealing ring 223,
Cartridge outlet passage 224 can be directly with heat exchanger 10 first flow connect.Valve element intake channel
At least a portion of 222 import is located at the valve element accommodating chamber 33 of the top of lug boss 65, link slot 31
Can be by the space between core assembly accommodating chamber 33 and second 221 and valve element intake channel 222
Connection.
It is of course also possible to be not provided with lug boss 65, now the external diameter of second 221 is more than the 4th aperture
64 internal diameter, the internal diameter of the internal diameter less than the 4th aperture 64 of the outlet of cartridge outlet passage 224, makes
Second 221 compression is resisted against on end plate 6.The present embodiment can be improved by setting lug boss 65
Second 221 and the sealing property of lug boss 65, prevent interior leakage.
So, after refrigerant is flowed into from the 4th aperture 34, flow to valve element import by link slot 31 and lead to
Road 222, heat exchange is flowed directly into by the refrigerant after valve module throttling by cartridge outlet passage 224
Device 10, the gas-liquid separation that produced in the flow process of intermediate distance that can be very good to reduce refrigerant shows
As, the heat exchange property of heat exchanger is improved, the degree of superheat can be preferably controlled, but also heat can be improved
The resistance to shock of switch.
During assembling, flow plate 8, end plate 6, base plate 7, installing plate, the first adapter 1, second are taken over
4 and the 3rd adapter 5 welded together by the form of soldering.Before welding, first by flow plate 8, end
Plate 6, base plate 7, installing plate, the first adapter 1, the second adapter 4 and the 3rd adapter 5 are completed,
It is fixed using special frock clamp；Then, then will press-fit flow plate 8, end plate 6,
Base plate 7, installing plate, the first adapter 1, the second adapter 4 and the 3rd adapter 5 are welded in being put into stove.
The mode of welding using vacuum drying oven can carry out vacuum brazing or carry out nitrogen protection using continuous tunnel furnace
Weldering.After being welded, core assembly 22 and coil block 21 are installed on boss portion 32 successively.
