Then, here, the purpose for especially emphasizing setting corrugated flexible hose 43 is then represented when corrugated flexible hose 43 expands Heat transfer block internal gas is filled with, it is possible to reduce or stop air demand;When corrugated flexible hose 43 is shunk, then heat transfer block is represented Internal gas is insufficient, needs to supply.
Second seal assembly 2 include by the sealing element 20 of heat transfer block outlet end part seal, setting the outside of sealing element 20 with The form-fitting splint 21 that locating clip 5 contacts.
Specifically, the material of sealing element 20 is identical as the material of sealing panel 10, the material of form-fitting splint 21 and sizing face Plate 11 is identical.
In addition, locating clip 5 includes horizontally disposed support panel 50, is fixed on the positioning of support panel 50 by grid module 51, the activity being arranged on support panel 50 and form adjustable holding region between grid module 51 with positioning moved horizontally Module 52 and the actuator 53 of the driving movement of active module 52.
It is equipped on support panel 50 and (does not show along the sliding slot that heat transfer block heat exchanger channels direction extends, but be not difficult in figure Expect), active module 52 is sticked on support panel 50 and the lower end of active module 52 is additionally provided with and the matched guiding of sliding slot Module (it is not shown in figure, but it is contemplated that).
As for actuator 53 comprising be fixed on the fixed module 530 on support panel 50, the length direction along sliding slot Extend and be threadedly engaged with fixed module screw rod 531, be rotatably arranged on active module 52 around the center position of screw rod 531 Steering knuckle 532 and driving wheel disc 533, wherein the one end of screw rod 531 is connected with steering knuckle 532, the other end It is connected with driving wheel disc 533.
Specifically, steering knuckle 532 includes the interconnecting module being rotatably arranged on active module 52 by bearing a, wherein Interconnecting module is equipped with the threaded hole b to match with screw rod 531.
How to be operated as locating clip 5, belongs to means commonly used in the art, it is not described in detail herein.
Meanwhile positioning is arranged in parallel between grid module 51, active module 52,530 three of fixed module.
In conclusion the present embodiment implementation process is as follows:
Heat transfer block after cutting is put into the clamping zone of locating clip 5, and air inlet end and outlet side are respectively facing positioning By grid module 51 and active module 52, then by the first seal assembly 1 and the second seal assembly 2 be fitted in respectively heat transfer block G into Outlet end then drives active module 52 is mobile to realize clamping, and at this point, the connector 41 of air inlet pipe 4 from frustum outer surface Contradict the taper type short slot in gas passage 3, while underrun sealing ring 42 and be formed panel 11 of the connector 41 from frustum Medial surface contradicts, and then, is docked by interface with supply air line, is directly inflated into heat transfer block G, until corrugated flexible hose 43 expands Afterwards, air demand is adjusted, then observation is gas leakage place, so that completion cuts the leak point positioning of rear heat transfer block G.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention, All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it It is interior.
