Road is as second outlet pipeline 104, so that the housing 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 is engaged with lid 12 and forms the installation cavity 101,
The import, first outlet and second outlet can be engaged with the connecting line in place heat-exchange system loop, specifically institute
It can be one to state inlet ductwork 102, first outlet pipeline 103 and the second outlet pipeline 104 of housing and the distribution body
Attachment 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 valve element
Component 2 includes the first valve block 21, the second valve block 22 and running part 23, and the housing 1, which has, is located at the installation cavity bottom side
Stopper protrusion 13, resettlement section 1011, specifically stopper protrusion, resettlement section 1011 be respectively provided with fan-shaped outline, the resettlement section with
The stopper protrusion is complementary in housing to be set, defined herein " complementation is set " be for the bottom section of housing, it is described
Resettlement section occupies a part for 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 resettlement section and the complementary setting of stopper protrusion in housing inner bottom part regional extent.First valve block 21 is at least
Part is located at the resettlement section 1011, and stopper protrusion 13 can be circumferential to the progress of the first valve block spacing so that the first valve block 21
Setting is relatively fixed relative to housing, defined herein " being relatively fixed setting " refers to that the first valve block can move in allowed band,
First valve block 21 is located in the resettlement section 1011 so as to also substantially be set and the limit into complementation with stopper protrusion 13
Accordingly, first valve block 21 is substantially set in fan-shaped for position convex portion, can reduce the volume of the first valve block, reduce material into
This, and the downside of the first valve block directly contacts and sealed set or close by setting seal to carry out in addition with the housing
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 is carried on the back with its upper side
To setting, the downside of the second valve block contacts 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 first, second valve block is vertical, i.e., the second valve block is rotated central axial direction, 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 less than the limit convex
The upper side 131 in portion 13, the upper side of 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, the gap is not more than the thickness of first valve block between the upper side of the downside of valve block and the stopper protrusion
Size, specifically, the thickness of first valve block is 3mm~9mm, such as 4mm, 5mm, 6mm, 7mm equidimension, and this first
