In-out end liquid cooling interface, two in-out end liquid coolings are respectively arranged in the opposite two side walls of the jet vectoring chamber
There is certain horizontal distance D between interface.Realize the useful effect of liquid cooling medium.
As one of preferred embodiment of the invention, the cross section of the cross rib slot is triangle, and the cross rib slot hangs down
Directly it is provided on longitudinal fin.
The longitudinal fin and rib slot upper head plate are integrally formed.It can effectively realize the transmitting of heat.
The punching rib wall support chip includes two panels support plate, and two panels support plate, which links together, constitutes triangular structure,
The length of the support plate is of same size with jet vectoring chamber.It can effectively realize the drainage to liquid cooling medium.
Multiple jet holes are opened up in two panels support plate respectively, the jet hole in two panels support plate has height difference H.With one
Fixed difference in height enables to the flow field of liquid cooling medium to disturb and reinforces.
Described every shin is triangle, and punching rib wall support chip is held between shin and cross rib slot.
The height of the longitudinal fin is less than the height of jet vectoring chamber, the height and jet vectoring chamber of the longitudinal fin
Height have difference in height h.
