Small part is contained in the installation cavity, and distribution body 11 described further is assembled with 12 phase of lid, specifically the distribution body
11 are respectively arranged with screw mounting hole with the lid 12, the two assembling can be realized relatively fixed set by screw elements 4
It sets, the shell 1 carries out assembling fixation also by thread connecting mode with control unit 3.
The shell 1 has at least one import, at least one outlet, in present embodiment shell 1 have the first pipeline,
Second pipeline, third pipeline, wherein the first pipeline is inlet ductwork 102, the second pipeline is first outlet pipeline 103, third pipe
Road is as second outlet pipeline 104, so that the shell 1 has import 1201, first outlet 1301 and second outlet 1401,
Form the three-port structure of One In and Two Out；Specifically the distribution body 11 matches with lid 12 and forms the installation cavity 101,
The import, first outlet and second outlet can be matched with the connecting line in place heat-exchange system circuit, specifically institute
Inlet ductwork 102, first outlet pipeline 103 and the second outlet pipeline 104 and the distribution body for stating shell can be one
Connection structure.Incorporated by reference to shown in Fig. 6 to Fig. 8, the core assembly 2 is at least partially housed in the installation cavity 101, the spool
Component 2 includes the first valve block 21, the second valve block 22 and running part 23, and the shell 1, which has, is located at the installation cavity bottom side
Stopper protrusion 13, receiving portion 1011, specifically stopper protrusion, receiving portion 1011 all have fan-shaped outer profile, the receiving portion with
The stopper protrusion complementary setting in shell, defined herein " complementation setting " be for the bottom section of shell, it is described
Receiving portion occupies a part of the bottom section and stopper protrusion occupies another part of the bottom section, especially from depression angle
From the point of view of degree, the receiving portion setting complementary with stopper protrusion within the scope of bottom section in shell.First valve block 21 is at least
Part is located at the receiving portion 1011, and stopper protrusion 13 can carry out circumferential limit to the first valve block, so that the first valve block 21
Relative to the relatively fixed setting of shell, defined herein " relatively fixed setting " refers to that the first valve block can move within the allowable range,
First valve block 21 is located in the receiving portion 1011 to be also substantially arranged and the limit at complementary with stopper protrusion 13
Position protrusion correspondingly, the substantially fan-shaped setting of the first valve block 21, can reduce the first valve block volume, reduce material at
This, and the downside of the first valve block and the shell directly contact and sealed set or close by addition setting sealing element progress
Envelope；For purposes of illustration only, the upper side of the first valve block is in contact with the second valve block, the downside of first valve block and its upper side are carried on the back
To setting, the downside of the second valve block is contacted with first valve block, the upper side of the second valve block then with the second valve block downside
Back to setting.The defined herein direction perpendicular with first valve block 21, the second valve block is vertical direction, and specifically this is vertical
Plane where direction and the first, second valve block is vertical, i.e. central axial direction that the second valve block is rotated also is understood as institute
The axis direction of installation cavity or the axis direction of running part are stated, the downside of first valve block 21 is lower than the limit convex
The upper side of the upper side 131 in portion 13, first valve block is higher than or the equal upper side in the stopper protrusion 13, and described
The downside of two valve blocks and the upper side of the stopper protrusion are at least partly oppositely arranged, on the vertical direction, described second
There is gap, which is not more than the thickness of first valve block between the downside of valve block and the upper side of the stopper protrusion
Size, specifically, the thickness of first valve block is 3mm~9mm, such as 4mm, 5mm, 6mm, 7mm equidimension, this first
Valve block is excessively thin, is not easy to be manufactured and structural strength is poor, and blocked up meeting relative increase integral product height dimension is unfavorable for minimizing
