[0045] The medium in the heat exchange tube bundle 1 is water or air.

[0046] The liquid tank 2 is conformal with the inner wall of the cabin 3.

[0047] The liquid tank 2 is made of corrosion-resistant, high-thermal-conductivity and high-strength material.

[0048] The specific structure and function of the present application are as follows:

[0049] The device is used in deep sea environment, and the heat exchange tube bundle 1 is used for carrying heat exchange medium and is located on both sides of the inner wall of the cylindrical cabin 3, mainly comprising a plurality of longitudinal heat exchange tubes 101, a transverse heat exchange tube 102, a busbar 103, a first medium inlet 105, a first medium outlet 106 and a medium discharge port, etc., and the whole is conformally installed on the inner side of the cabin wall of the deep sea manned platform.

[0050] The heat exchange tube is used for carrying heat exchange medium, the longitudinal heat exchange tube 101 is longitudinally and side by side installed on the inner side of the cabin wall of the deep sea manned platform, closely adheres to the cabin wall, the transverse heat exchange tube 102 is transversely installed on the inner side of the cabin wall, closely adheres to the cabin wall, and is communicated with the upper end of each longitudinal heat exchange tube 101, and both ends are closed. The pipe wall of the longitudinal heat exchange tube 101 and the transverse heat exchange tube 102 is made of high-thermal-conductivity and high-strength material, which is used for heat exchange between the medium in the pipe and the air in the cabin 3 and the cabin wall, and bears external force during transportation and installation. The first medium inlet 105 is located at the lower end of the first longitudinal heat exchange tube 101 of the heat exchange tube bundle 1, which provides an inlet passage for the circulation of the medium in the heat exchange tube bundle 1. The first medium outlet 106 is located at the lower end of the last longitudinal heat exchange tube 101 of the heat exchange tube bundle 1, which provides an outlet passage for the circulation of the medium in the heat exchange tube bundle 1.

[0051] The busbar 103 is transversely installed on the inner side of the cabin wall of the deep sea manned platform, closely adheres to the inner wall, is communicated with the lower end of the longitudinal heat exchange tube 101 except the first and the last, both ends are closed, and is used for discharging the medium in the heat exchange tube through the busbar 103 by gravity. The busbar 103 is made of high-thermal-conductivity and high-strength material, which is used for heat exchange between the medium in the pipe and the air in the cabin 3 and the cabin wall, and bears external force during transportation and installation.

[0052] The discharge pipe 104 is located on the lower side of the busbar 103 and is longitudinally arranged, and the upper end thereof is communicated with the busbar 103. The first discharge port 107 is located at the lower end of the discharge pipe 104, which provides a passage for the discharge of the medium.

[0053] The inlet valve 108 is located at the first medium inlet 105 of the heat exchange tube bundle 1, which is used for opening / closing the medium inlet. The outlet valve 109 is located at the first medium outlet 106 of the heat exchange tube bundle 1, which is used for opening / closing the medium outlet.

[0054] The drain valve 110 is located at the first drain port 107, which is a one-way valve for opening / closing the drain port.

[0055] The pump 111 is located in front of the inlet valve 108, which provides power for the medium entering the heat exchange tube bundle 1.

[0056] The liquid tank 2 is located at the bottom of the cabin 3, which is designed to conform to the cabin wall and is installed closely to the cabin wall. It contains heat exchange medium and is made of corrosion-resistant, high-thermal-conductivity, and high-strength materials.

[0057] The liquid tank 2 mainly includes an outer shell 201, a second medium inlet 202, a second medium outlet 203, and a second drain port 204.

[0058] The outer shell 201 is composed of a surrounding wall and upper and lower cover plates, which forms a closed space for containing heat exchange medium.

[0059] The second medium inlet 202 is located on the upper cover plate of the outer shell 201 and is connected to the first medium outlet 106 of the heat exchange tube bundle 1. The second medium outlet 203 is located on the upper cover plate of the outer shell 201 and is connected to the first medium inlet 105 of the heat exchange tube bundle 1. The second drain port 204 is located in the middle of the upper cover plate of the outer shell 201 and is connected to the first drain port 107 of the heat exchange tube bundle 1.

[0060] The heat exchange tube bundle 1 and the liquid tank 2 form a circulation loop through the medium inlet and the medium outlet. The medium in the liquid tank 2 passes through the second medium outlet 203, the pump 111, the first medium inlet 105 into the heat exchange tube bundle 1, then passes through the first medium outlet 106 of the heat exchange tube bundle 1 and the second medium inlet 202 back to the liquid tank 2, completing a single cycle.

[0061] The medium in the heat exchange tube bundle 1 is water or air.

[0062] The water in the liquid tank 2 exchanges heat with seawater through the cabin wall, absorbs the cold of seawater, and lowers the temperature. The low-temperature water enters the heat exchange tube bundle 1 through the pump 111, exchanges heat with the air in the cabin 3 through the tube wall, and the air in the cabin 3 releases heat and lowers the temperature. The medium water absorbs heat and raises the temperature, and the medium water with raised temperature reenters the liquid tank 2 through circulation in the heat exchange tube bundle 1 and exchanges heat with seawater through the cabin wall to lower the temperature. Through the above process, the heat exchange between the air in the cabin 3 and the seawater outside is promoted. At the same time, the seawater outside exchanges heat with the water in the tube bundle through the cabin wall and absorbs the heat of the cabin 3.

[0063] After the medium water in the heat exchange tube bundle 1 is drained, the tube bundle is filled with air, and the closed space formed by the slender tube bundle reduces the flowability of the air inside and the heat conduction performance, thereby blocking the heat transfer between the air in the cabin 3 and the seawater outside.

[0064] During the process of the deep-sea manned platform floating, diving and working, there is a temperature difference between the temperature of cabin 3, the seawater temperature and the design temperature.

[0065] When the seawater temperature is higher than the design temperature, the pipe bundle is filled with air, which blocks the heat transfer from the outside seawater to the cabin 3 air.

[0066] When the seawater temperature is equal to the design temperature, or the cabin 3 air needs to obtain / release heat from / to the high / low temperature outside seawater, the pipe bundle is filled with medium water, which promotes the heat transfer between the cabin 3 air and the outside seawater, and keeps the temperature of the cabin 3 within the design range.

[0067] When the seawater temperature is lower than the design temperature, the pipe bundle is filled with air, which blocks the heat transfer from the cabin 3 air to the outside seawater.

[0068] The heat exchange pipe bundles 1 on both sides of the cabin wall are independently controlled for adjusting the heat exchange amount with the seawater. When both sides of the heat exchange pipe bundles 1 are filled with medium water, the heat exchange amount is the largest; when one side is filled with medium water, the heat exchange amount is the second; and when both sides of the heat exchange pipe bundles are filled with air, the heat exchange amount is the smallest.

[0069] The heat exchange pipe adopts a flat cross section. For the cylindrical shell cabin wall coordinate system, the radial diameter is longer and the tangential diameter is shorter. This shape can increase the thickness of the radial medium layer, promote heat transfer and heat blocking.

[0070] In actual work process:

[0071] According to the deep-sea manned platform task profile heat load statistics and the diving depth, the device control strategy is developed. When the temperature of the cabin 3 is higher than the design temperature and higher than the outside seawater temperature, the medium water is filled into the heat exchange pipe bundle 1, the heat of the cabin 3 is transferred outward, and the temperature of the cabin 3 is reduced. When the temperature of the cabin 3 is lower than the design temperature and lower than the outside seawater temperature, the medium water in the heat exchange pipe bundle 1 is discharged, the medium in the heat exchange pipe bundle 1 is air, the heat transfer coefficient is reduced, the outward heat transfer amount is reduced, and the temperature of the cabin 3 is maintained.

[0072] When the depth is 0m-60m, the outside seawater temperature is 29℃-25℃, which is higher than the design temperature, the inlet valve 108, the outlet valve 109 and the discharge valve 110 are closed, the heat exchange pipe bundle 1 is kept as non-flowing air, the heat transfer rate of the outside heat to the cabin is reduced, and the temperature rising speed of the cabin 3 is slowed down.

[0073] When the depth is 60m-400m, the temperature of the outside seawater is 25℃-10℃, which is close to the design temperature, and the temperature of the cabin is slightly higher due to the heat accumulation. The pump 111, the inlet valve 108 and the outlet valve 109 are opened, the discharge valve 110 is closed, and the medium water is filled into the single-side heat exchange tube bundle 1 to transfer the heat in the cabin to the outside, thereby reducing the temperature of the cabin 3. With the heat accumulation in the cabin 3, the medium water is filled into the double-side heat exchange tube system to increase the heat exchange amount to the outside, thereby keeping the temperature of the cabin 3 in the design range.

[0074] When the depth is 400m-2000m, the temperature of the outside seawater is 10℃-2.4℃, which is far lower than the design temperature of the cabin 3. In order to keep the temperature of the cabin 3 in the design range, the pump 111, the inlet valve 108 and the outlet valve 109 are closed, the discharge valve 110 is opened, and the medium water in the heat exchange tube system is discharged to reduce the heat transfer coefficient of the seawater to the cabin through the cabin wall, thereby reducing the heat transfer from the cabin to the outside.
