[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-3 The embodiment of the utility model provides a technical solution: a transformer rectifier with a liquid cooling channel, comprising a transformer rectifier 1, a processing plate 2 is installed inside the transformer rectifier 1, a cooling and cooling pipe 3 for circulation is connected through the surface of the processing plate 2, a heat conducting plate 4 is detachably mounted on the bottom end of the processing plate 2, and a through hole 5 that matches the cooling and cooling pipe 3 is opened on the surface of the heat conducting plate 4;

[0025] A cooling bin 6 is installed at the inner bottom end of the transformer rectifier 1, and two external connecting pipes 7 are connected through the side wall of the cooling bin 6. One end of the two external connecting pipes 7 passing through the cooling bin 6 is connected through the inlet and outlet of the cooling circulation pipe 9. One end of the cooling circulation pipe 9 away from the external connecting pipe 7 is respectively connected to the transmission pipe 10, and the ends of the two connecting pipes 7 away from the cooling bin 6 are fixed and connected through a connection interface 8.

[0026] When in use, when performing a liquid cooling cycle, the purpose of cooling is achieved from multiple directions by balancing the temperature through heat transfer and arranging pipes around the main body of the processing plate 2. During the liquid cooling cycle, the cooling efficiency is improved by adding multiple connected pipes for cold sources to balance the heat on the surface of the main body of the processing plate 2. Compared with traditional cooling methods, the cooling efficiency and utilization rate of liquid cooling are improved.

[0027] As shown in the figure, the top end of the transmission pipe 10 passes through the through hole 5 and is connected to the cooling pipe 3.

[0028] When in use, cryogenic liquid is circulated through interconnected pipes.

[0029] As shown in the figure, the bottom end of the processing plate 2 is fixed to the heat conducting plate 4 via a threaded connector, and the bottom end of the heat conducting plate 4 is fixed to the top end of the cooling chamber 6 .

[0030] When in use, the heat generated by the processing plate 2 is absorbed by the heat conducting plate 4 and at the same time contacts with the cooling chamber 6 to achieve heat transfer balance, thereby achieving the purpose of cooling.

[0031] As shown in the figure, the cooling and temperature reduction pipe 3, the cooling circulation pipe 9, the transmission pipe 10 and each connecting pipe inside the transformer rectifier 1 are all provided with a layer of iron protective sheath for preventing leakage through the outer periphery.

[0032] When in use, an iron protective cover is used to protect the internal pipes to prevent pipe rupture and damage to the equipment during use.

[0033] As shown in the figure, the connection interface 8 is connected to an external connection interface 11 for circulating cooling opened on the outer wall of the transformer rectifier 1.

[0034] When in use, cooling circulation of the liquid is achieved through a pipeline interface connected to the cooling mechanism.

[0035] The working principle and use process of the utility model are as follows: first, the external interface 11 is connected to the pipeline of the refrigeration equipment, and then the coolant is input into the external interface 11, and enters the cooling circulation pipe 9 from the connecting interface 8 and the external connecting pipe 7, until the internal pipeline is completely filled, and liquid flows back from the liquid outlet, completing the circulation detection of the liquid cooling channel, and then starting the transformer rectifier 1. In the process of heat dissipation during the operation of the processing board 2, the heat is absorbed by the heat conduction plate 4. The heat conduction plate 4 is in contact with the cooling bin 6 at the same time, and the heat is transferred to the low-temperature cooling bin 6 surface to complete the heat balance of the heat transfer. The cooling bin 6 maintains a low temperature by continuously inputting cooling liquid into the cooling circulation pipe 9. At the same time, the cooling circulation pipe 9 passes through the transmission pipe 10 through the through hole 5 to let the low-temperature liquid flow through the interior of the cooling and cooling pipe 3. The cooling and cooling pipe 3 will also reduce the temperature around the main body of the processing board 2.
