DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0023] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0025] A demineralized water cooling device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0026] See also Figure 1-Figure 9 According to an embodiment of the present application, a demineralized water cooling device includes: a frame mechanism 1, a shell heat exchange mechanism 2 and a guide and separation mechanism 3.

[0027] The frame mechanism 1 is used to support and install the outer shell heat exchange mechanism 2 and the flow guide partition mechanism 3. The arrangement of the outer shell heat exchange mechanism 2 and the flow guide partition mechanism 3 enables a single cover to have a larger heat conduction area, thereby improving the cooling heat conduction efficiency of the cooling device.

[0028] See also Figure 1-Figure 6The frame mechanism 1 includes a first vertical plate 11, a second vertical plate 12 and a bracket 14. Both sides of the first vertical plate 11 and the second vertical plate 12 are fixedly connected by a fixing rod 13. The bracket 14 is located on one side of the second vertical plate 12, and the first vertical plate 11, the second vertical plate 12 and the bracket 14 are connected by a connecting rod 15. The shell heat exchange mechanism 2 includes a cover plate 21, a connecting shell 22 and a rear cover shell 23. The connecting shell 22 is arranged between the cover plate 21 and the rear cover shell 23, and the first vertical plate 11 and the second vertical plate 12 clamp and fix the cover plate 21, the connecting shell 22 and the rear cover shell 23. A heat medium outlet pipe 25 and a refrigerant liquid inlet end pipe fitting 26 are respectively connected on one side of the cover plate 21, and a heat medium inlet pipe 24 and a refrigerant liquid outlet end pipe fitting 27 are respectively connected on the back of the rear cover shell 23. The flow guiding and dividing mechanism 3 is arranged inside the connecting housing 22 and the rear housing 23, and the flow guiding and dividing mechanism 3 includes a first spiral plate 31 and a second spiral plate 32, which are arranged in layers and staggered, and the ends of the first spiral plate 31 and the second spiral plate 32 are connected and sealed by an end partition 33. The first spiral plate 31, the second spiral plate 32, and the end partition 33 enclose a first cavity, and the outer areas of the first spiral plate 31, the second spiral plate 32, and the end partition 33 constitute a second cavity, and the back of the connecting housing 22 is respectively provided with a first through hole 221 and a second through hole 222 for guiding.

[0029] The working principle of the desalted water cooling device is as follows: the high-temperature desalted water enters the second cavity in the outer area of ​​the first spiral plate 31, the second spiral plate 32, and the end partition plate 33 inside the rear cover 23 from the heat medium inlet pipe 24. The desalted water in the second cavity inside the rear cover 23 will flow along the outer spiral area formed by the first spiral plate 31 and the second spiral plate 32, and then enter the first cavity enclosed by the first spiral plate 31, the second spiral plate 32, and the end partition plate 33 inside the first connection cover 22 from the second through hole 222 on the back of the first connection cover 22, and after circulating in the spiral area once more, it will enter the second cavity in the second connection cover 22 through the first through hole 221 on the second connection cover 22, and finally flow out from the heat medium outlet pipe 25 on the side of the cover plate 21. At the same time, the refrigerant fluid enters the first cavity surrounded by the first spiral plate 31, the second spiral plate 32, and the end partition plate 33 inside the second group of connecting cover shells 22 through the second through hole 222, and then enters the first cavity inside the rear cover shell 23 through the first through hole 221 on the back of the first group of connecting cover shells 22, and is finally discharged through the refrigerant liquid outlet pipe 27 on the back of the rear cover shell 23.

[0030] The desalted water cooling device can achieve rapid cooling by heat exchange in two ways: first, the hot desalted water and the refrigerant in the rear cover 23 and the connecting cover 22 are separated by the cavity formed by the first spiral plate 31 and the second spiral plate 32, respectively, and the hot desalted water and the refrigerant are heat exchanged through the first spiral plate 31 and the second spiral plate 32. Second, the liquids flowing in the first cavity or the second cavity between the adjacent connecting cover 22 and the connecting cover 22 are liquids with different temperatures, and the hot desalted water and the refrigerant flowing in the two different connecting covers 22 can be heat-conducted through the wall plate at the back of the connecting cover 22; similarly, the liquids flowing in the first cavity or the second cavity between the connecting cover 22 and the rear cover 23 are liquids with different temperatures, and the hot desalted water and the refrigerant flowing in the connecting cover 22 and the rear cover 23 can be heat-conducted through the wall plate at the back of the connecting cover 22. The desalted water cooling device can conduct heat through the wall panels of the connecting cover 22 and the rear cover 23, and can also complete heat exchange through the first spiral plate 31 and the second spiral plate 32. The relative number of connecting covers 22 and rear covers 23 has a better cooling effect than the traditional plate heat exchanger.

[0031] Among them, an even number of connecting shells 22 are arranged between the cover plate 21 and the rear shell 23, and are not limited to the two groups shown in the figure. The first through hole 221 and the second through hole 222 provided on the connecting shell 22 are inclined through holes, which can respectively connect the first cavity and the second cavity inside different shells on both sides of the back plate of the connecting shell 22, so that different cold and hot liquids can flow inside the first cavity or the second cavity inside the adjacent shells, and the cold and hot liquids inside the adjacent shells are in the same cavity, and heat exchange can be better completed through the back plate in the connecting shell 22.

[0032] For specific settings, see Figure 6 The side of the cover plate 21 close to the connection shell 22 and the side of the connection shell 22 close to the rear shell 23 are both provided with a sealing gasket 29. The sealing gasket 29 is used to seal the seal between the cover plate 21 and the connection shell 22, and the seal between the connection shell 22 and the rear shell 23. The outer edge of the back of the cover plate 21 and the connection shell 22 can be provided with a snap ring, and the front of the connection shell 22 and the rear shell 23 is provided with a groove matched with the snap ring, and the groove is provided with a sealing ring of an annular structure. The snap ring is inserted into the groove and sealed by the sealing ring, so as to achieve a better sealing effect between the cover plate 21 and the connection shell 22, between adjacent connection shells 22, and between the connection shell 22 and the rear shell 23.

[0033] For further information, see Figure 3 and Figure 5The shell heat exchange mechanism 2 also includes a support 28, which is respectively arranged on the outside of the connecting shell 22 and the rear shell 23. The fixing rod 13 is inserted into the slot on the support 28. The slot on the support 28 cooperates with the fixing rod 13, so that the connecting shell 22 and the rear shell 23 are more firmly fixed between the first vertical plate 11 and the second vertical plate 12.

[0034] For details, please refer to Figure 3 , Figure 7 and Figure 8 The first vertical plate 11 and the second vertical plate 12 are both provided with a mounting groove 111 on their sides, and the fixing rod 13 is inserted through the mounting groove 111. The fixing rod 13 includes a first screw 131 and a first nut 132. The first screw 131 passes through the mounting groove 111, and the first vertical plate 11 and the second vertical plate 12 are connected through the first screw 131 and the first nut 132. The desalted water cooling device also includes a pressurized anti-loosening mechanism 4, which includes an outer cylinder shell 41, an inner cylinder shell 42 and a flexible ring sheet 43. The inner cylinder shell 42 is sleeved on the outside of the first screw 131 located between the second vertical plate 12 and the first nut 132, and the outer cylinder shell 41 is located outside the inner cylinder shell 42. Two flexible ring sheets 43 are respectively arranged at both ends of the outer cylinder shell 41 and the inner cylinder shell 42. The outer cylinder shell 41, the inner cylinder shell 42, and the flexible ring sheet 43 constitute a liquid storage cavity, and the refrigerant liquid outlet end pipe 27 is connected to the liquid storage cavity constituted by the outer cylinder shell 41, the inner cylinder shell 42, and the flexible ring sheet 43 through the guide mechanism 5.

[0035] The use of the first screw 131 and the first nut 132 to fix the first vertical plate 11 and the second vertical plate 12 is a common installation and fixing method for plate heat exchangers. The demineralized water cooling device in the present application can utilize the pressure in the refrigerant outlet pipe 27. A small portion of the refrigerant liquid in the refrigerant outlet pipe 27 enters the liquid storage cavity formed by the outer cylinder shell 41 and the inner cylinder shell 42 through the guide mechanism 5. The liquid storage cavity is subjected to the pressure of the liquid, and the flexible ring sheets 43 on both sides of the outer cylinder shell 41 and the inner cylinder shell 42 bulge outward, with axial force to support the first nut 132, which plays a certain role in preventing loosening.

[0036] In the above specific implementation, please refer to Figure 4 , Figure 5 and Figure 6The refrigerant liquid inlet end pipe fitting 26 includes a refrigerant inlet pipe 261 and a first connecting pipe 262. One end of the first connecting pipe 262 is connected with the refrigerant inlet pipe 261, and the other end of the first connecting pipe 262 passes through the cover plate 21 and is connected with the first cavity formed by the first spiral plate 31, the second spiral plate 32, and the end partition plate 33. The refrigerant inlet pipe 261 is provided with a first check valve 263. The refrigerant liquid outlet end pipe fitting 27 includes a refrigerant outlet pipe 271 and a second connecting pipe 272. One end of the second connecting pipe 272 is connected with the refrigerant outlet pipe 271, and the other end of the second connecting pipe 272 passes through the back of the rear cover 23 and is connected with the first cavity formed by the first spiral plate 31, the second spiral plate 32, and the end partition plate 33. The second connecting pipe 272 is provided with a pressure regulating valve 273.

[0037] Following the above-mentioned embodiment, the refrigerant liquid passes through the refrigerant inlet pipe 261 and the first one-way valve 263 in the refrigerant inlet end pipe 26, and then passes through the first connecting pipe 262 to enter the first cavity formed by the first spiral plate 31, the second spiral plate 32, and the end partition plate 33 inside the connecting shell 22. The refrigerant liquid in the first cavity inside the rear shell 23 is finally discharged into the refrigerant outlet pipe 271 through the second connecting pipe 272. Through the arrangement of the first one-way valve 263 and the pressure regulating valve 273, the liquid entering the liquid storage cavity of the outer cylinder shell 41 and the inner cylinder shell 42 from the refrigerant outlet pipe 271 through the guide mechanism 5 has a more stable and greater pressure, and the flexible ring pieces 43 on both sides of the outer cylinder shell 41 and the inner cylinder shell 42 can continuously and more stably press against the first nut 132, further improving the anti-loosening effect of the first nut 132. When the flexible ring piece 43 at one end of the outer cylinder shell 41 and the inner cylinder shell 42 is pressed against the first nut 132, the flexible ring piece 43 at the other end is pressed against the second vertical plate 12, so that the cover plate 21, the connecting cover shell 22, and the rear cover shell 23 between the first vertical plate 11 and the second vertical plate 12 can be fitted and fixed more tightly, thereby improving the stability of the connection between the cover plate 21, the connecting cover shell 22, and the rear cover shell 23.

[0038] The flexible ring piece 43 may preferably be made of a rubber material sheet with good elasticity.

[0039] Further, the fixing rod 13 includes a first bushing 133, which is disposed inside the mounting groove 111 on the side of the first vertical plate 11, and the first screw 131 is disposed through the first bushing 133. The fixing rod 13 includes a second bushing 134, which is disposed inside the mounting groove 111 on the side of the second vertical plate 12, and the first screw 131 is disposed through the second bushing 134. The first bushing 133 and the second bushing 134 are disposed to stably support the first screw 131 installed inside the mounting groove 111.

[0040] The above-mentioned desalted water cooling device adopts the water pressure in the refrigerant outlet pipe 271 between the first connecting pipe 262 and the second connecting pipe 272, and cannot pressurize the liquid in the liquid storage chamber between the outer cylinder shell 41 and the inner cylinder shell 42, so as to further enhance the anti-loosening effect of the first nut 132.

[0041] In the above specific implementation, please refer to Figure 7 , Figure 8 and Fig. 9 The flow guiding mechanism 5 includes a barrel 51, a tank cover 52, an extrusion adjustment component 53, a liquid injection pipe 55 and a flow guiding pipe 57. The barrel 51 is fixed on the outside of the second vertical plate 12, and the tank cover 52 is fixed to the end of the barrel 51 and sealed. The tank cover 52 and the barrel 51 are fixed by bolts. The extrusion adjustment component 53 is installed on the tank cover 52 to squeeze the internal space of the barrel 51. The barrel 51 and the refrigerant outlet pipe 271 are connected through the liquid injection pipe 55, and a second one-way valve 56 is arranged outside the liquid injection pipe 55. The barrel 51 and the liquid storage cavity formed by the outer cylinder shell 41, the inner cylinder shell 42 and the flexible ring sheet 43 are connected through the flow guiding pipe 57, and a third one-way valve 58 is arranged outside the flow guiding pipe 57. A pressure gauge 54 is installed on the outside of the barrel 51. The extrusion adjustment component 53 includes a piston 531, a second nut 532, a second screw 533 and a knob 534. The piston 531 is located inside the barrel 51, the second nut 532 is fixed on the outside of the tank cover 52, one end of the second screw 533 is rotatably arranged with the piston 531, the other end of the second screw 533 movably passes through the tank cover 52 and is threadedly engaged with the second nut 532, and the knob 534 is arranged at the end of the second screw 533 away from the piston 531.

[0042] The working principle of the pressurized anti-loosening is as follows: the liquid in the second connecting pipe 272 enters the barrel 51 through the liquid injection pipe 55 and the second one-way valve 56, and the liquid in the barrel 51 enters the liquid storage cavity between the outer cylinder shell 41 and the inner cylinder shell 42 through the guide pipe 57 and the third one-way valve 58. The pressure gauge 54 is provided to observe the pressure inside the barrel 51, which is roughly the pressure in the liquid storage cavity inside the outer cylinder shell 41 and the inner cylinder shell 42. When the pressure in the liquid storage chamber inside the outer cylinder shell 41 and the inner cylinder shell 42 needs to be increased, the second screw 533 in 530 is rotated. The rotating second screw 533, in cooperation with the second nut 532, drives the piston 531 to move toward the side of the tank cover 52 in advance. At this time, the liquid inside the second connecting pipe 272 can be pumped into the barrel 51 through the injection pipe 55 and the second one-way valve 56; then the knob 534 is rotated in the opposite direction. The knob 534 rotated in the opposite direction will push the piston 531 to squeeze the liquid inside the barrel 51 through the second screw 533. The pressurized liquid inside the barrel 51 will enter the liquid storage cavity inside the outer cylinder shell 41 and the inner cylinder shell 42 through the guide tube 57 and the third one-way valve 58, so that the liquid inside the liquid storage cavity is pressurized. At this time, the actual pressure of the pressure gauge 54 is the pressure inside the liquid storage cavity between the outer cylinder shell 41 and the inner cylinder shell 42. The liquid storage cavity is further pressurized, and the flexible ring sheet 43 between the outer cylinder shell 41 and the inner cylinder shell 42 is further squeezed and bulged outward, so that the first nut 132 can be more tightly fitted and squeezed in the axial position, and the anti-loosening effect of the first nut 132 can be further improved, that is, the first vertical plate 11 and the second vertical plate 12 can further fix the cover plate 21, the connecting cover shell 22 and the rear cover shell 23 more tightly, and the stability of the connection between the cover plate 21, the connecting cover shell 22 and the rear cover shell 23 is further improved.
