[0003] The current cabinet water cooling is mostly connected to the fresh water + seawater series dual-circuit centralized water cooling system, with complex series-parallel pipe networks and long heat transfer links.

[0041] Figure 1 A schematic structural diagram of a flexible blanket-applied micropump liquid cooling system according to the present invention is shown.

[0042] Among them, the figure markings are: 1-flexible blanket heat exchanger, 2-micropump liquid cooling device, 3-first tube plug flexible composite joint, 4-second tube plug flexible composite joint, 5-coating material, 6-installation and fastening structural parts, a, b, c and d-four pipe openings of the micropump liquid cooling device. DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Unless otherwise specified, various raw materials, reagents, instruments and equipment used in this application can be purchased from the market or prepared by existing methods.

[0045] The following takes the liquid cooling cycle of the underwater submersible shell and the control room cabinet (i.e., the control cabinet) as an example to explain the flexible blanket-applied micropump liquid cooling system provided by the present invention. The flexible blanket-applied micropump liquid cooling system of the present invention can also be applied to similar environmental systems.

[0046] Example 1

[0047] like Figure 1 As shown, a flexible blanket-applied micropump liquid cooling system includes a flexible blanket heat exchanger 1, a micropump liquid cooling device 2, a first pipe-plug flexible composite joint 3, a second pipe-plug flexible composite joint 4, a coating material 5 and an installation and fastening structure 6. The liquid cooling system is used to control the liquid cooling cycle of the cabinet, and its specific structure is described as follows.

[0048] Specifically, the flexible blanket heat exchanger 1 is a flexible blanket-type thin-layer heat exchanger with a heat transfer fluid channel integrated in a high thermal conductivity composite matrix material, which is tightly attached to the outer wall of an underwater submersible (i.e., Figure 1 The outer surface of the flexible blanket heat exchanger 1 is coated with a coating material 5 composed of a heat insulating material and a protective layer, which is pressed and fixed on the outer shell of the underwater submersible through the installation and fastening structure 6. The flexible blanket heat exchanger 1 can meet the needs of different heat dissipation by adjusting the effective heat transfer area of ​​the application. The application surface selection is flexible and easy to upgrade and transform with the technical innovation of the high thermal conductivity composite matrix material.

[0049] The micro pump liquid cooling device 2 comprises a built-in micro low noise circulating liquid cooling pump, a liquid supply process pipe section inlet and outlet pipe plugs, a liquid return process pipe section inlet and outlet pipe plugs, a sensor device and an intelligent control chip, etc. Among them, the sensor device comprises a micro liquid cooling medium temperature sensor and a flow meter.

[0050] like Figure 1 As shown, the micropump liquid cooling device 2 controls the flow of liquid cooling fluid, transfers the heat dissipation of the liquid cooling back plate of the cabinet to the flexible blanket heat exchanger 1 through the liquid supply process pipe section, and directly transfers it to the seawater environment (i.e., the ocean heat sink) through the metal shell (shell) under the waterline of the underwater submersible. Compared with the transmission link in which the heat dissipation of the liquid cooling back plate of the traditional cabinet is transferred to the seawater cooling system through a complex series-parallel centralized fresh water cooling circulation loop and finally dispersed into the seawater environment, the heat transfer link is greatly shortened. At the same time, there is no problem of the cooling seawater medium penetrating the pressure-bearing boundary of the shell. The method of directly transferring the heat to the marine environment by the outer metal shell and naturally cooling the seawater outside the ship has the characteristics of good safety and low noise.

[0051] Combined with the temperature and flow measured by the micro liquid cooling medium temperature sensor and flow meter, the intelligent control chip adjusts the flow of the micro low-noise circulating liquid cooling pump in real time, and stably and reliably controls the liquid cooling heat dissipation of the cabinet liquid cooling backplane, which can meet the needs of key special users with small liquid cooling flow and high requirements for cooling stability and reliability.

[0052] The first pipe-inserted flexible composite joint 3 is used to connect the inlet and outlet of the cabinet liquid cooling backplane and the micro-pump liquid cooling device 2, that is, the pipe openings a and d of the micro-pump liquid cooling device 2 are connected through the liquid supply process pipe and the liquid return process pipe. The second pipe-inserted flexible composite joint 4 connects the pipe openings b and c of the micro-pump liquid cooling device 2 and the liquid cooling inlet and outlet of the flexible blanket heat exchanger 1 through the liquid supply process pipe and the liquid return process pipe. Both ends of the first pipe-inserted flexible composite joint 3 and the second pipe-inserted flexible composite joint 4 are standard pipe plugs, and the joint line has a built-in two-way liquid flexible pipe for inlet and outlet, and a flexible protective sleeve on the outer cover. The length is preset and adjustable, which can realize flexible laying, and also has the advantages of good expansibility and easy adaptation.

[0053] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
