Detailed implementation manners

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced for effective description of the technical content.

[0025] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0026] As Figure 1 、Figure 2 As shown, at least one embodiment provides a phase change liquid-cooled immersion blade server cabinet, including: a housing 1, inside which several heat-generating element groups 2 are arranged. An independent jet mechanism 3 is arranged between adjacent heat-generating element groups 2, and each jet mechanism 3 is connected to a water pump to achieve liquid supply. Under different temperature conditions of the heat-generating element group 2, the liquid supply flow rate to the jet mechanism 3 is adjusted by the water pump, so as to switch between cleaning the bubbles attached to the heat-generating element group 2 and efficiently dissipating heat from the heat-generating element group 2.

[0027] In this embodiment, temperature data of the heat-generating element group 2 is collected by a temperature sensor; the control module is electrically connected to the water pump and the temperature sensor, and the control module controls the power of the water pump according to the temperature data collected by the temperature sensor to adjust the liquid supply flow rate of the jet mechanism 3.

[0028] In some embodiments, the control module can but is not limited to using a PLC.

[0029] As Figure 2 shown, in some embodiments, an inlet pipe 11 penetrates through the housing 1, and an outlet pipe (not shown in the figure) and an air outlet 12 are provided. The heat-generating element group 2 and the jet mechanism 3 are installed inside the housing 1, and a cooling medium is contained inside the housing 1 to dissipate heat from the heat-generating element group 2.

[0030] In this embodiment, the water pump is connected to the inlet pipe 11 and the outlet pipe of the housing 1, so as to realize the circulating flow of the cooling medium; at the same time, the housing 1 is vertically arranged, and by controlling the total amount of the cooling medium inside the housing 1, no cooling medium will flow out of the air outlet 12.

[0031] As Figure 2 shown, in some embodiments, the heat-generating element group 2 includes several heat-generating elements 22 arranged in a straight line, and a heat dissipation gap 23 is left between adjacent heat-generating elements 22 to facilitate the passage of the cooling medium; however, when the heat-generating element group 2 is working normally, the cooling medium in the heat dissipation gap 23 is easily vaporized to form bubbles on the side walls of the heat-generating elements 22.

[0032] To solve the above problems, in some embodiments, the jet orifice group 321 on the side wall of the rising and falling groove member 32 is corresponded to the position of the heat dissipation gap 23, so that the ejected cooling medium can pass through each heat dissipation gap 23, thereby cleaning the bubbles to improve the heat dissipation efficiency of the heat-generating element 22.

[0033] As Figure 3 shown, in some embodiments, an installation position 211 is opened on the bottom surface of the flow-through channel 21, and the lower limit groove member 31 is arranged in the installation position 211.

[0034] In this embodiment, when the heating element group 2 starts to work initially, in order to facilitate the cooling medium in the flow-through channel 21 to dissipate heat from the heating elements 22 on both sides, the lower limit groove member 31 is arranged in the installation position 211 lower than the heating element 22, and the upper lifting groove member 32 is close to the lower limit groove member 31, thereby preventing the upper lifting groove member 32 from blocking the cooling medium in the flow-through channel 21.

[0035] As Figure 3 shown, in some embodiments, there is a flow-through channel 21 left between adjacent heating element groups 2, and a jet mechanism 3 is placed in the flow-through channel 21. The jet mechanism 3 can eject a cooling medium to clean the bubbles attached to the heating element groups 2 on both sides or dissipate heat from the heating element groups 2 efficiently by increasing the circulation volume.

[0036] In this embodiment, when the heating element group 2 starts to work initially, its temperature is lower than the first preset temperature (for example: the first preset temperature is 40 degrees Celsius), and no bubbles will be generated on the side walls of the heating element group 2 and efficient heat dissipation is not required; when the heating element group 2 works normally, its temperature is higher than the first preset temperature and lower than the second preset temperature (for example: the second preset temperature is 80 degrees Celsius). At this time, bubbles formed by the vaporization of the cooling medium due to the temperature rise will adhere to the side walls of the heating element group 2. At this time, the cooling medium is sprayed onto the heating element group 2 to clean the bubbles; when the heating element group 2 works at high power, its temperature is higher than the second preset temperature, and at this time, it is necessary to accelerate the flow of the cooling medium in the housing 1 for efficient heat dissipation.

[0037] As Figure 3 shown, in some embodiments, the jet mechanism 3 includes: a lower limit groove member 31 and an upper lifting groove member 32. The upper lifting groove member 32 is inserted into the lower limit groove member 31 to form a flow channel 33.

[0038] As Figure 4 shown, in some embodiments, the inlet portion 332 of the flow channel 33 is opened on the lower limit groove member 31. The inlet portion 332 is a through hole 310, and the flow channel 33 is communicated with the inlet pipe 11 through this through hole 310.

[0039] As Figure 4 shown, in some embodiments, a jet port group 321 is opened on the side wall of the upper lifting groove member 32.

[0040] As Figure 5 shown, in some embodiments, the outlet portion 331 of the flow channel 33 is opened on the upper lifting groove member 32. The outlet portion 331 is a notch 322.

[0041] In this embodiment, when a cooling medium is introduced into the flow channel 33, the pressure in the flow channel 33 increases, thereby pushing the ascending and descending groove member 32 to rise; wherein, when the flow rate of the cooling medium introduced into the flow channel 33 changes, the rising height of the ascending and descending groove member 32 will also change accordingly.

[0042] Specifically, the ascending and descending groove member 32 has three states: The first state (as shown in Figure 6 ) is that when the heating element group 2 starts to work initially, the control module controls the water pump to stop working. At this time, the ascending and descending groove member 32 fits with the lower limit groove member 31. The jet orifice group 321 on the side wall of the ascending and descending groove member 32 is blocked by the lower limit groove member 31, and the outlet portion 331 of the flow channel 33 is blocked by the lower limit groove member 31; The second state (as shown in Figure 7 ) is that when the heating element group 2 is working normally, the control module controls the water pump to make the cooling medium enter the flow channel 33 at a first preset flow rate (for example: the first preset flow rate is 5 ml / s). At this time, the ascending and descending groove member 32 rises to a first preset height (for example: the first preset height is 5 mm) to expose the jet orifice group 321, and the cooling medium sprays out from the jet orifice group 321, thereby cleaning the bubbles on the side wall of the heating element group 2. At this time, the outlet portion 331 of the flow channel 33 is still blocked by the lower limit groove member 31; The third state (as shown in Figure 8 ) is that when the heating element group 2 is working at high power, the control module controls the water pump to make the cooling medium enter the flow channel 33 at a second preset flow rate (for example: the second preset flow rate is 10 ml / s). At this time, the ascending and descending groove member 32 rises to a second preset height (for example: the second preset height is 8 mm) to block the exposed jet orifice group 321, and at the same time expose the outlet portion 331 of the flow channel 33, so that the cooling medium sprays out faster from the outlet portion 331 of the flow channel 33, accelerating the flow of the cooling medium in the housing 1, thereby efficiently dissipating heat from the heating element group 2.

[0043] In some embodiments, the inlet pipe 11 extends into the housing 1, so that the flow channels 33 of each jet mechanism 3 are all communicated with the inlet pipe 11 through the through holes 310 of the inlet portion 332.

[0044] As shown in Figure 9 , in some embodiments, the notch 322 is arranged close to the notch 323 of the ascending and descending groove member 32.

[0045] In this embodiment, when the heating element group 2 starts to work initially and when the heating element group 2 is working normally, the notch 322 is always blocked by the lower limit groove member 31; wherein, the area of the exposed notch 322 is larger than the total area of the jet orifice group 321.

[0046] As shown in Figure 6As shown, in some embodiments, the cross-section of the up and down chute member 32 is T-shaped and includes: a lifting portion 32a and a guiding portion 32b; the lifting portion 32a is inserted into the lower limit chute member 31, and the guiding portion 32b is slidably disposed in the flow passage 21; the jet port group 321 is located on the side wall of the lifting portion 32a.

[0047] In this embodiment, the sliding fit between the guiding portion 32b and the flow passage 21 can prevent the up and down chute member 32 from shaking during the lifting process; at the same time, due to the presence of the guiding portion 32b in the flow passage 21, the heating element 22 is limited, thereby preventing the heating element 22 from shaking when impacted by the water flow.

[0048] As Figure 7 , Figure 8 As shown, in some embodiments, a linkage flap 34 is disposed in the flow channel 33, and a flow-through hole group 341 corresponding to the jet port group 321 is formed in the side wall of the linkage flap 34, and a first spring 35 is connected to the lower end surface of the linkage flap 34.

[0049] In this embodiment, when the heating element group 2 starts to work and during the normal operation of the heating element group 2, the first spring 35 always pushes the linkage flap 34 against the bottom of the up and down chute member 32, so that the linkage flap 34 rises synchronously with the up and down chute member 32, and during the rising process, the flow-through hole group 341 is ensured to communicate with the jet port group 321 to facilitate the outflow of the cooling medium.

[0050] As Figure 8 As shown, in some embodiments, when the heating element group 2 operates at high power, the first spring 35 pushes the linkage flap 34 to rise with the up and down chute member 32 to a first preset height and then stops rising (at this time, the elastic force of the first spring 35 can no longer drive the linkage flap 34 to rise); subsequently, the up and down chute member 32 continues to rise, so that the flow-through hole group 341 is misaligned with the jet port group 321, that is, the jet port group 321 is blocked.

[0051] As Figure 8 As shown, in some embodiments, the lifting portion 32a is connected to the lower bottom 311 of the lower limit chute member 31 by a second spring 36; wherein, the function of the second spring 36 is to pull the up and down chute member 32 to move back to its original position. The specific number of the second springs 36 can be set according to actual needs, and the elastic coefficient of the first spring 35 is less than the elastic coefficient of the second spring 36.

[0052] In some embodiments, the jet port group 321 is formed on the two side walls of the lifting portion 32a to respectively correspond to the heat dissipation gaps 23 of the two side heating element groups 2; the linkage flap 34 corresponds to the jet port group 321 of the lifting portion 32a and is provided with two pieces. Flow-through hole groups 341 are formed on both of the two linkage flaps 34, and a plurality of connecting rods are disposed between the two linkage flaps 34 to form an integral body of the two linkage flaps 34.

[0053] At least one embodiment provides a working method for a phase change liquid-cooled immersion blade server cabinet, including: when the temperature of the heat-generating element group 2 is lower than the first preset temperature, the control module controls the water pump to stop working, and the upper lifting groove member 32 is placed in the lower limit groove member 31; when the temperature of the heat-generating element group 2 exceeds the first preset temperature, the control module controls the water pump to make the cooling medium enter the flow channel 33 at the first preset flow rate, and drives the upper lifting groove member 32 to rise to the first preset height to expose the jet orifice group 321 on its side wall to clean the bubbles attached to the corresponding heat-generating element group 2; when the temperature of the heat-generating element group 2 exceeds the second preset temperature, the control module controls the water pump to make the cooling medium enter the flow channel 33 at the second preset flow rate, drives the upper lifting groove member 32 to rise to the second preset height, makes the linkage flap 34 block the jet orifice group 321, and at the same time opens the outlet part 331 of the flow channel 33 for efficient heat dissipation.

[0054] For the specific structure and implementation process of the phase change liquid-cooled immersion blade server cabinet, refer to the relevant discussions in the above embodiments, which will not be elaborated here.

[0055] In summary, the phase change liquid-cooled immersion blade server cabinet and its working method realize the switching between cleaning the bubbles attached to the heat-generating element group 2 and efficiently dissipating heat from the heat-generating element group 2 by setting the jet mechanism 3 and changing the liquid supply flow rate to the jet mechanism 3 by the water pump under different temperature conditions of the heat-generating element group 2.
