Referring to fig. 7, in the illustrated embodiment of the present invention, four distribution holes 221 are formed in each layer and are uniformly distributed along the circumferential direction of the extension 22. With such an arrangement, when the distribution holes 221 are capable of uniformly spraying the refrigerant into the internal cavity 10, the medium to be cooled in the cooling medium pipe 3 can be cooled more quickly and uniformly.
The upper portion of the distribution pipe 2 is sealed, so that the refrigerant can be injected into the internal cavity 10 only through the distribution holes 221. In the illustrated embodiment of the invention, the upper part of the dispensing tube 2 is fixed to the top cover 12. Specifically, in the illustrated embodiment of the present invention, the upper portion of the extending portion 22 extends upward through the first through hole 121 of the top cover 12, and the dispensing tube 2 includes a plug 23 fixed to the upper portion of the extending portion 22. Of course, in other embodiments, the upper portion of the dispensing tube 2 may also be welded and fixed to the bottom of the top cover 12 to achieve upper sealing.

The cooling medium pipe 3 passes through the second through hole 122 upward, and is welded and fixed to the top cover 12. The cooling medium inlet 32 and the cooling medium outlet 33 communicate with the cooling medium passage 30. In the illustrated embodiment of the invention, the cooling medium inlet 32 and the cooling medium outlet 33 are both located at the top of the cooling medium pipe 3. Specifically, the cooling medium inlet 32 and the cooling medium outlet 33 both protrude upward from the top cover 12.
Referring to fig. 4, in the illustrated embodiment of the present invention, the extension portion 22 is located at the center of the internal cavity 10, and the main body portions 31 of the plurality of cooling medium pipes 3 are located at the outer periphery of the extension portion 22. Along the radial direction of the shell 1, the plurality of cooling medium pipes 3 are arranged in an inner ring and an outer ring, wherein the cooling medium inlets 32 and the cooling medium outlets 33 of the same cooling medium pipe 3 are located on the same ring. The distance between two adjacent pipes is equal to the bending diameter of the U-shaped cooling medium pipe 3, and the same cooling medium pipe 3 is used.
The heat insulation layer 5 is wrapped on the outer side of the circumferential wall 11 to prevent external heat from heating the two-phase spray type multi-channel cooling tank 100 and consuming part of liquid refrigerants.

In the illustrated embodiment of the invention, there are three brackets 6 to provide better stability. Each of the brackets 6 includes a fixing portion 61 fixed to the circumferential wall 11 by welding, a first bending portion 62 extending horizontally outward in the radial direction of the housing 1 from the fixing portion 61, a second bending portion 63 extending downward from the first bending portion 62, and a support portion 64 extending horizontally outward in the radial direction of the housing 1 from the second bending portion 63. Preferably, the insulating layer 5 covers the welding portion of the bracket 6 and the circumferential wall 11 to protect the welding portion and improve the aesthetic appearance of the product.
The two-phase spray type multi-channel cooling tank 100 has a slender structure, and a small amount of refrigerant R (see fig. 6) is stored in the bottom of the internal cavity 10, but the depth is relatively deep. The refrigerant R flowing to the bottom of the internal cavity 10 can further cool the U-bend of the cooling medium pipe 3, thereby improving the cooling effect.
Compared with the prior art, in the two-phase spray-type multi-channel cooling tank 100 of the present invention, the refrigerant flows into the distribution cavity 220 from the refrigerant inlet 210 and is uniformly sprayed into the internal cavity 10 through the distribution holes 221; the medium to be cooled flows from the cooling medium inlet 32 into the cooling medium passage 30; the refrigerant absorbs heat and evaporates on the surface of the main body part 31 of the cooling medium pipe 3, so as to cool the medium in the cooling medium pipe 3, the refrigerant takes heat out from the refrigerant outlet 40 positioned above after being heated and evaporated, and the cooled cooling medium flows out from the cooling medium outlet 33, so that a good cooling effect is achieved.
