Specific implementation mode
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 2, a kind of transfer block applied to heat exchanger, including integrally formed switching block main body 1 and interconnecting piece
2, the interconnecting piece 2 is arc-shaped, and the inner surface of interconnecting piece 2 and the outer surface of header 3 fit, and further includes that setting is turning
Connect the rotation confinement block 4 on block main body 1 or interconnecting piece 2, header 3 is equipped with the through-hole 5 of perforation 3 tube wall of header, described turn
The size of dynamic confinement block 4 is adapted with the size of through-hole 5, when rotation confinement block 4 is caught in through-hole 5, header 3 and interconnecting piece
2 is circumferentially fixed.
The utility model, in use, the inner surface of interconnecting piece 2 is fitted in the outer surface of header 3, rotation limitation at this time
Block 4 is caught in through-hole 5 so that the rotation of opposing connections 2 can not occur for header 3, therefore thoroughly solves transfer block and carrying out
The problem of rotation is easy to happen when furnace brazing improves the consistency of soldering effect and product, and is only rotated by increasing
This structure of confinement block 4 realizes purpose, therefore smaller to the change of the overall structure of transfer block, and processing and manufacturing is simple, while right
Other performances of product not will produce any influence.
Transfer block includes that integrally formed switching block main body 1 and interconnecting piece 2, interconnecting piece 2 are arc-shaped, and radian and afflux
The radian of pipe 3 is identical, so that the inner surface of interconnecting piece 2 and the outer surface of header 3 can preferably fit, rotation limitation
The setting of block 4 is adapted in switching block main body 1 or interconnecting piece 2 with the through-hole 5 on header 3, in use, by interconnecting piece 2
Inner surface is fitted in the outer surface of header 3, rotates confinement block 4 at this time and is caught in through-hole 5 so that phase can not occur for header 3
Rotation to interconnecting piece 2, therefore thoroughly solve the problems, such as that transfer block is easy to happen rotation when carrying out furnace brazing, improve pricker
The consistency of effect and product is welded, and only this structure realizes purpose by increase rotation confinement block 4, therefore to transfer block
Overall structure change it is smaller, processing and manufacturing is simple, while not will produce any influence to other performances of product.
Specifically, the rotation confinement block 4 is integrally formed with switching block main body 1, and is rotated confinement block 4 and protruded from switching
The inner surface of block main body 1, before carrying out furnace brazing, under the effect of external force so that rotation confinement block 4 is embedded in through-hole 5, to
Keep header 3 and interconnecting piece 2 circumferentially fixed, it is preferable that rotation confinement block 4 can be such that transfer block more stablizes in this way there are two setting.
Specifically, the rotation confinement block 4 is integrally formed with interconnecting piece 2, and is rotated confinement block 4 and protruded from interconnecting piece 2
Inner surface, when interconnecting piece 2 and header 3 fit, in rotation confinement block 4 i.e. embedded through-hole 5, to make header 3
It is circumferentially fixed with interconnecting piece 2, it is preferable that rotation confinement block 4 can be such that transfer block more stablizes in this way there are two setting.
Preferably, the described switching one end of block main body 1 far from interconnecting piece 2 is equipped with guiding surface 15, the guiding surface 15
The distance between switching 1 axial line of block main body is gradually reduced from the side far from interconnecting piece 2 to the other side, in this way can be quickly accurate
Extension tube attached really is installed.
Preferably, the center of the interconnecting piece 2 and the angle α of the line at 2 both ends of interconnecting piece are 90-180 degree, can be protected in this way
The radian for demonstrate,proving interconnecting piece 2 is more than 180 degree, makes the connection area with bigger between interconnecting piece 2 and header 3.
In conjunction with shown in Fig. 1 and Fig. 2, the switching block main body 1 includes integrally formed fixed part 11 and positioning region 12, external
Tube passage 13 penetrates through fixed part 11 and positioning region 12 up to the outer surface of header 3, further includes protruding from table in positioning region 12
The positioning table 14 in face, extension tube attached is by penetrating through fixed part 11 and positioning region 12 until the extension tube attached of the outer surface of header 3 is logical
Road 13 is connected to inside header 3, and the quick location and installation of extension tube attached can be realized by protruding from the positioning table 14 of 12 inner surface of positioning region.
The operation principle of the utility model is：In use, the inner surface of interconnecting piece 2 is fitted in the outer surface of header 3,
Rotation confinement block 4 is caught in through-hole 5 at this time so that the rotation of opposing connections 2 can not occur for header 3, therefore thoroughly solve
The problem of transfer block is easy to happen rotation when carrying out furnace brazing improves the consistency of soldering effect and product, and only
By increase rotation confinement block 4, this structure realizes purpose, therefore smaller, processing and manufacturing is changed to the overall structure of transfer block
Simply, while to other performances of product any influence is not will produce, after the completion of soldering, extension tube attached is using guiding surface 15 and determines
Position platform 14 can rapidly and accurately realize installation.
