Figures 1 to 6 As shown: An underwater heat exchange device, the device comprises a support frame 1 and a double-body shell and tube heat exchanger 2, the bottom of the support frame 1 is fixed on a pre-buried concrete block at the bottom of the water,

[0023] The twin-body shell and tube heat exchanger 2 includes a first monomer heat exchanger 3 and a second monomer heat exchanger 4 connected as an integral structure. The first monomer heat exchanger 3 and the second monomer heat exchanger 4 have the same structure.

[0024] The first monomer heat exchanger 3 is composed of a base and an upper shell. A connecting plate 5 is provided at the bottom of the base, and the connecting plate 5 is fixed on the pre-buried concrete block at the bottom of the water. The inner cavity of the base is divided into a liquid inlet cavity 7 and a liquid outlet cavity 8 by a longitudinal partition 6. A liquid inlet pipeline 9 connected to the liquid inlet cavity 7 and a liquid outlet pipeline 10 connected to the liquid outlet cavity 8 are also provided on the base.

[0025] The liquid outlet pipeline 10 of the first monomer heat exchanger 3 is connected to the liquid inlet pipeline 9 of the second monomer heat exchanger 4, and the liquid inlet pipeline 9 of the first monomer heat exchanger 3 and the liquid outlet pipeline 10 of the second monomer heat exchanger 4 are both connected to the coolant circulation system.

[0026] The top of the base is provided with a plurality of buckles 11 evenly distributed in the circumferential direction, and the upper shell and the base are fixedly connected by the buckles 11. The bottom of the upper shell of the first monomer heat exchanger 3 is provided with a first water inlet pipeline 12, and the top is provided with a first water outlet pipeline 13. The top of the upper shell of the second monomer heat exchanger 4 is provided with a second water inlet pipeline 14 connected to the first water outlet pipeline 13, and the bottom is provided with a second water outlet pipeline 15. The first water inlet pipeline 12 and the second water outlet pipeline 15 are connected to the seawater circulation system.

[0027] A cooling liquid circulation pipe group 16 is arranged in the upper shell, and the cooling liquid circulation pipe group 16 is composed of a plurality of circulation pipes. The inlet end of the cooling liquid circulation pipe group 16 is connected to the opening on the top plate of the liquid inlet chamber 7, and the outlet end is connected to the opening on the top plate of the liquid outlet chamber 8.

[0028] A plurality of semicircular baffles 17 are arranged on the coolant circulation pipe group 16. Adjacent baffles 17 are arranged alternately, and a guide plate 18 is also arranged on the top surface of the uppermost baffle 17.

[0029] An auxiliary bracket 19 is also fixedly arranged outside the upper shell, and a buckle 11 is arranged at the end of the auxiliary bracket 19. The buckle 11 can be connected to the crossbeam 20 on the top of the support frame 1. At the same time, a gasket 21 is also arranged between the auxiliary bracket 19 and the side of the crossbeam 20.

[0030] The guide plates 18 are multiple and distributed at equal central angles.

[0031] The working process of the underwater heat exchange device of the embodiment of the utility model is as follows: when the server is running, the coolant circulation system matched with the server works, and the coolant absorbs the heat generated when the server is working, so that the server always runs in a low temperature environment;

[0032] Under the action of the pump in the coolant circulation system, the coolant enters the liquid inlet cavity 7 of the first monomer heat exchanger 3 through the liquid inlet pipe 9, and then enters the coolant circulation pipe group 16 under the action of pressure, flows through the coolant circulation pipe group 16 and enters the liquid outlet cavity 8 of the first monomer heat exchanger 3, and then enters the second monomer heat exchanger 4 through the liquid outlet pipe 10, and returns to the coolant circulation system after completing the same flow path;

[0033] Similarly, the pump in the seawater circulation system works to pump seawater into the inner cavity of the first monomer heat exchanger 3 through the first water inlet pipe 12, and the seawater flows from bottom to top in the inner cavity of the first monomer heat exchanger 3, and enters the second monomer heat exchanger 4 through the first water outlet pipe 13 and the second water inlet pipe 14, and the seawater flows from top to bottom in the inner cavity of the second monomer heat exchanger 4, and finally returns to the seawater circulation system through the second water outlet pipe 15;

[0034] In the above process, seawater flows in the shell layer and coolant flows in the tube layer, and sufficient heat exchange can be carried out between them. The heat carried by the coolant is absorbed by the seawater, and the coolant changes from a high temperature state back to a low temperature state, and re-participates in the cooling cycle of the server; that is, this underwater heat exchange device can quickly and efficiently disperse the heat generated by the server when it is working to the marine environment to ensure that it can operate in an appropriate low temperature environment.

[0035] Since the multiple semicircular baffles 17 arranged on the coolant circulation pipe group 16 are staggered and distributed to form an S-shaped channel, this design can ensure that the seawater is fully in contact with each coolant pipe, making the heat exchange more uniform, thereby achieving the purpose of improving the heat exchange efficiency.

[0036] After long-term use, some marine organisms (such as shellfish) and algae will attach to the outer wall of each cooling circulation pipe as seawater enters the pipe layer. When they grow up, they will form a biological layer on the outer wall of the cooling circulation pipe. The existence of this biological layer will affect the heat exchange efficiency between the coolant and seawater, so it needs to be cleaned regularly.

[0037] When cleaning is required, the diver dives underwater with cleaning tools, first opens the buckle 11 at the end of the auxiliary bracket 19 to separate the auxiliary bracket 19 from the crossbeam 20, then opens the buckle 11 on the base to separate the base from the upper shell, pulls out the upper shell vertically to expose the coolant circulation pipe group 16 inside, and the diver uses the cleaning tool to clean it. After cleaning, the upper shell is buckled from top to bottom onto the coolant circulation pipe group 16 again. During this process, the guide plate 18 provided on the top surface of the uppermost baffle 17 can play a guiding role to ensure that the upper shell can be smoothly inserted into the coolant circulation pipe group 16; after being plugged in place, the buckle 11 is used again to fix the base and the upper shell, and to fix the auxiliary bracket 19 to the crossbeam 20.
