[0035] The present invention also provides an electronic device, including the heat dissipation system of any one of the above.

[0036] The beneficial effects of the heat dissipation system provided by the present invention are as follows: Through the setting of the jet cooling component, a cooling cavity is provided inside the jet cooling component. By using the cooling cavity, space can be provided for the heat exchange of the jet working fluid. The jet cooling component is in contact connection with the shell to be cooled. Specifically, the outer side of the bottom of the cooling cavity of the jet cooling component is in contact with the shell to be cooled. Then, a heat conduction structure is formed at the bottom of the cooling cavity of the jet cooling component. The heat from the shell to be cooled is transferred to the inner side of the bottom of the cooling cavity through the outer side of the bottom of the cooling cavity of the jet cooling component. Since the heat of the shell to be cooled has been transferred to the jet cooling component, only the jet cooling component needs to be cooled. At the same time, since the heat of the shell to be cooled is transferred to the jet cooling component, the temperature of the shell to be cooled drops, and there is a temperature difference between the shell to be cooled and the heating element, which is beneficial for the heat dissipated by the heating element to continue to be transferred to the shell to be cooled, thereby realizing the continuous heat dissipation of the jet cooling component to the heating element. Regarding the heat transfer between the heating element and the shell to be cooled, it can be achieved by setting a heat conduction component between the heating element and the shell to be cooled. Or, a heat conduction component can also be set to penetrate the shell to be cooled and then contact the jet cooling component. During the process of the heat conduction component penetrating the shell to be cooled, it can also contact the shell to be cooled, so that part of the heat dissipated from the heating element is transferred to the shell to be cooled, and another part can be directly transferred to the jet cooling component, which can further improve the heat dissipation efficiency of the jet cooling component to the heating element. By using the setting of the jet cooling component, the jet working fluid does not need to be in direct contact with the heating element. At the same time, not only the high efficiency of jet impingement cooling is fully utilized, but also the influence of the jet working fluid on the heating element is avoided, thereby reducing the requirements for the type of jet working fluid and eliminating the need to consider factors such as corrosion and insulation of the jet working fluid on the heating element. Moreover, the contact between the jet working fluid and the heating element is avoided. When the heating element needs to be maintained, the application environment of the heating element is dry and there is not much liquid interference, which is convenient for maintenance. In addition, a jet nozzle is used to provide the jet working fluid for the jet cooling component, and the jet cooling component is cooled by the jet working fluid, thereby realizing the cooling of the shell to be cooled, and further realizing the cooling effect on the heating element in the shell to be cooled. After the jet nozzle and the jet cooling component are assembled, the installation position on the shell to be cooled can be selected according to the setting, without occupying the internal space of the shell to be cooled, which is convenient for layout and avoids affecting the internal structure layout of the shell to be cooled.

[0037] The heat dissipation system provided by the present invention requires no contact between the jet working fluid and the heating element. Therefore, the requirements for the type of jet working fluid are low, which is beneficial to cost reduction and higher safety. At the same time, since the heating element does not need to contact the jet working fluid, the disassembly, installation and maintenance of the housing to be cooled are more convenient. Moreover, the structural layout of this heat dissipation system is reasonable, which is beneficial to miniaturization design, does not occupy the internal space of the housing to be cooled, is beneficial to the layout of the housing to be cooled, has low manufacturing cost, and has high heat dissipation efficiency at the same time.

[0038] In one embodiment, by providing a flow supply and impact assembly, the flow supply and impact assembly is used to provide jet working fluid for the jet nozzle. At the same time, the flow supply and impact assembly includes a medium pipeline, a jet working fluid box, liquid-cooled heat dissipation fins and a power component. The jet working fluid box, the liquid-cooled heat dissipation fins and the power component are all connected in the medium pipeline. Specifically, the jet working fluid box is used to store the jet working fluid, that is, the jet working fluid is stored in the jet working fluid box. Through the medium pipeline, the inflow or outflow of the jet working fluid into or out of the jet working fluid box is realized. Specifically, one end of the medium pipeline connected to the jet working fluid box is communicated with the water inlet pipe, and the other end is communicated with the water outlet pipe. Through the settings of the medium pipeline, the water inlet pipe and the water outlet pipe, a circulation loop is formed to realize the circulating flow of the jet working fluid between the jet cooling component and the jet working fluid box. Then, the liquid-cooled heat dissipation fins and the power component can be installed in the circulation loop. A number of fins are provided on the liquid-cooled heat dissipation fins, and the jet working fluid flows through the fins to dissipate heat for the jet working fluid. The power component is used to provide power for the flow of the jet working fluid to ensure the circulating flow of the jet working fluid in the circulation loop, so as to ensure that the jet working fluid absorbs heat in the jet cooling component and dissipates heat in the liquid-cooled heat dissipation fins, and continuously supplies the jet cooling component with jet working fluid at a lower temperature.

[0039] The electronic device provided by the present invention is provided with the above heat dissipation system. Since the heat dissipation system has the above technical effects, the electronic device provided with this heat dissipation system should also have corresponding technical effects.

[0059] The core of the present invention is to provide a heat - dissipation system and an electronic device, which have a reasonable layout, are convenient for disassembly and assembly, have a wide application range, and a long service life.

[0060] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0061] In jet - impingement heat transfer, a gas or a liquid is directly ejected onto the surface to be cooled or heated through a circular or slit - type jet nozzle 2 under the action of pressure, so that a strong heat - transfer effect is generated in the wall - surface area subjected to the impact. This method is a highly efficient heat - transfer enhancement method. Its characteristic lies in that the fluid can directly impact the surface, the flow path is shortened, a thinner boundary layer is formed near the stagnation point, and the shortening of the boundary layer effectively enhances the heat - transfer efficiency. Especially in the part directly opposite to the jet nozzle 2, the heat - transfer coefficient is much higher than that of conventional heat - dissipation methods, such as air - cooling and water - cooled plate heat - dissipation.

[0062] For servers, especially edge - type servers, due to the too - high power consumption of the heating element 100 and the harsh working environment, the server cannot dissipate heat in time, resulting in too - high temperature of the heating element 100. It is necessary to further find a method to improve the heat - dissipation ability of the server; jet - impingement cooling is a very efficient heat - transfer method. At present, most jet cooling is jet - working - fluid contact cooling, which has high requirements for the jet working fluid and is not convenient for the later maintenance of the server; at the same time, it also makes the internal design layout of the server complex; currently, most jet - cooled servers are used in indoor environments such as data centers, and there is a lack of a jet - cooling method that can be applied outdoors for enhanced heat - dissipation and prevent the heating element 100 from being too cold.

[0063] In this implementation manner, please refer to Figure 1 、 Figure 4 and Figure 6 , the heat - dissipation system includes:

[0064] The jet - cooling component 1 has a cooling cavity inside. The outer bottom of the cooling cavity is used to fit with the shell 3 to be cooled, so that the heat of the shell 3 to be cooled is transferred from the outer bottom of the cooling cavity to the inner bottom of the cooling cavity. There is a heating element 100 in the shell 3 to be cooled; specifically, the heating element 100 is a heating element 100 in an electronic device, generally including high - power - consumption heating elements 100 such as a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit) module, as well as other low - power - consumption heating elements 100;

[0065] The jet nozzle 2 is installed on the jet cooling component 1. The jet nozzle 2 is used to inject a jet working medium into the cooling cavity, and the jet nozzle 2 faces the inner side of the bottom of the cooling cavity.

[0066] Specifically, the jet cooling component 1 can be machined or formed by casting. The cooling cavity can be arranged at the central position of the jet cooling component 1 to ensure the stability and cooling uniformity of the jet cooling component 1. The outer side of the bottom of the cooling cavity, that is, the bottom shape of the jet cooling component 1, is adapted to the surface shape of the shell 3 to be cooled, so that the jet cooling component 1 can better fit with the shell 3 to be cooled and improve the heat transfer efficiency. The jet nozzle 2 is installed on the jet cooling component 1 and faces the cooling cavity. Since the bottom of the cooling cavity is the closest to the shell 3 to be cooled, the jet nozzle 2 is directed towards the inner side of the bottom of the cooling cavity, which can improve the cooling efficiency of the bottom of the cooling cavity and thus improve the cooling efficiency of the shell 3 to be cooled. Further, the shell 3 to be cooled can be the shell of an electronic device, and the electronic device can be a server, a host computer, etc. It should be noted that the side of the cooling cavity close to the shell 3 to be cooled is the bottom, that is, the bottom of the cooling cavity refers to the side of the cooling cavity close to the shell 3 to be cooled. When the position of the jet cooling component 1 changes, the bottom of the cooling cavity will also change accordingly.

[0067] This heat dissipation system is provided with a jet cooling component 1. The interior of the jet cooling component 1 is provided with a cooling cavity. By means of the cooling cavity, space can be provided for the heat exchange of the jet working fluid. The jet cooling component 1 is in contact connection with the shell 3 to be cooled. Specifically, the outer side of the bottom of the cooling cavity of the jet cooling component 1 is in contact with the shell 3 to be cooled. Then, a heat conduction structure is formed by the bottom of the cooling cavity of the jet cooling component 1. The heat from the shell 3 to be cooled is transferred to the inner side of the bottom of the cooling cavity through the outer side of the bottom of the cooling cavity of the jet cooling component 1. Since the heat of the shell 3 to be cooled has been transferred to the jet cooling component 1, therefore, only the jet cooling component 1 needs to be cooled. At the same time, since the heat of the shell 3 to be cooled is transferred to the jet cooling component 1, the temperature of the shell 3 to be cooled drops. There is a temperature difference between the shell 3 to be cooled and the heating element 100, which is conducive to the continuous transfer of the heat dissipated by the heating element 100 to the shell 3 to be cooled, thereby realizing the continuous heat dissipation of the jet cooling component 1 to the heating element 100. Regarding the heat transfer between the heating element 100 and the shell 3 to be cooled, it can be achieved by setting a heat conduction component 32 between the heating element 100 and the shell 3 to be cooled. Or, a heat conduction component 32 can also be set. The heat conduction component 32 penetrates through the shell 3 to be cooled and then contacts the jet cooling component 1. During the process of the heat conduction component 32 penetrating through the shell 3 to be cooled, it can also contact the shell 3 to be cooled, so that part of the heat dissipated from the heating element 100 is transferred to the shell 3 to be cooled, and another part can be directly transferred to the jet cooling component 1, which can further improve the heat dissipation efficiency of the jet cooling component 1 to the heating element 100.

[0068] Furthermore, by means of the setting of the jet cooling component 1, the jet working fluid does not need to be in direct contact with the heating element 100. At the same time, not only the high cooling efficiency of jet impingement is fully utilized, but also the influence of the jet working fluid on the heating element 100 is avoided. Thus, the requirements for the type of jet working fluid are reduced, and there is no need to consider the influence of factors such as corrosion and insulation of the jet working fluid on the heating element 100. Moreover, the contact between the jet working fluid and the heating element 100 is avoided. When the heating element 100 needs to be maintained, the application environment of the heating element 100 is dry and there is not too much liquid interference, which is convenient for maintenance.

[0069] Even further, the jet nozzle 2 is used to provide the jet working fluid for the jet cooling component 1. The jet cooling component 1 is cooled by the jet working fluid, thereby realizing the cooling of the shell 3 to be cooled, and further realizing the cooling effect on the heating element 100 in the shell 3 to be cooled. After the jet nozzle 2 and the jet cooling component 1 are assembled, the installation position on the shell 3 to be cooled can be selected according to the setting, without occupying the internal space of the shell 3 to be cooled, which is convenient for layout and avoids affecting the internal structure layout of the shell 3 to be cooled.

[0070] The heat dissipation system provided by the present invention has low requirements for the type of jet working fluid because the jet working fluid does not need to contact the heating element 100, which is beneficial to cost reduction and higher safety. At the same time, since the heating element 100 does not need to contact the jet working fluid, the disassembly, installation and maintenance of the housing 3 to be cooled are more convenient. Moreover, the structural layout of this heat dissipation system is reasonable, which is beneficial to miniaturization design, does not occupy the internal space of the housing 3 to be cooled, is beneficial to the layout of the housing 3 to be cooled, has low manufacturing cost, and has high heat dissipation efficiency at the same time.

[0071] In some embodiments, please refer to Figure 2 and Figure 3 , inside the cooling cavity, on the side close to the housing 3 to be cooled, a jet step 111 is provided. The jet step 111 is beneficial to the concentration of heat and ensures the effect of jet impingement cooling. The jet nozzle 2 is arranged towards the jet step 111. The jet nozzle 2 can be directly opposite to the central part of the jet step 111. Through the setting of the jet step 111, the distance between the jet nozzle 2 and the jet step 111 can be reduced, and the jet working fluid can be more fully sprayed onto the jet step 111, improving the cooling effect. The jet step 111 is located at the bottom of the cooling cavity, and the position of the jet step 111 corresponds to the position of the heating element 100 with relatively large heat generation in the component to be cooled. The jet step 111 extends towards the direction away from the component to be cooled, that is, the jet step 111 extends from the bottom of the cooling cavity to the middle of the cooling cavity, so that better heat conduction and heat dissipation can be carried out between the jet step 111 and the heating element 100 with relatively large heat generation.

[0072] In some embodiments, a diversion groove 112 is provided between the jet step 111 and the side wall of the jet cooling component 1. Specifically, the diversion groove 112 can surround the circumference of the jet step 111. The jet working fluid sprayed by the jet nozzle 2 onto the jet step 111 can flow into the diversion groove 112 through the jet step 111, which is convenient for collecting the jet working fluid and enables the jet working fluid to flow out of the outlet 115 of the jet cooling component 1 smoothly.

[0073] In some embodiments, a water inlet pipe 113 and a water outlet pipe 114 are further connected to the jet cooling component 1. The water inlet pipe 113 is connected to the jet nozzle 2, which is convenient for the water inlet pipe 113 to supply the jet working fluid to the cooling cavity of the jet cooling component 1. An outlet 115 is provided at the bottom of the side wall of the jet cooling component 1, and the water outlet pipe 114 is connected to the outlet 115, which is convenient for the jet working fluid in the cooling cavity of the jet cooling component 1 to flow along the outlet 115 into the water outlet pipe 114. Specifically, setting the outlet 115 at the bottom of the side wall of the jet cooling component 1 can facilitate the outflow of the jet working fluid from the cooling cavity under the action of gravity. Further, both the inlet and the outlet 115 of the jet cooling component 1 are threaded holes, and the jet nozzle 2 and the water outlet pipe 114 are respectively fixed on the jet cooling component 1 through the threaded holes, which is convenient for installation and has good sealing effect.

[0074] In some embodiments, the diversion channel 112 surrounds the periphery of the jet step 111. The bottom surface of the diversion channel 112 is an inclined surface, and the bottom surface gradually slopes downward from the side away from the outlet 115 to the side close to the outlet 115. Specifically, the lowest point in height in the diversion channel 112 is located at the outlet 115 of the cooling cavity. With such a setting, the jet working fluid can flow along the diversion channel 112 to the outlet 115 and enter the water outlet pipe 114. The highest position of the diversion channel 112 should also be lower than the height of the jet step 111 to prevent the liquid in the diversion channel 112 from submerging the jet step 111. Further, the inclination angle of the bottom surface of the cooling cavity is 5-10°. Except for the surface of the jet step 111 inside the cooling cavity, a hydrophobic coating with better hydrophobic effect is sprayed. The material of the hydrophobic coating can be selected as needed. The bottom surface of the cooling cavity and the superhydrophobic coating are conducive to the water flow ejected by the jet nozzle 2 to flow back into the water outlet pipe 114.

[0075] In some embodiments, please refer to Figure 1 and Figure 8 , the width of the jet cooling component 1 is smaller than the width of the housing 3 to be cooled, so as to form a bearing surface 34 on the surface of the housing 3 to be cooled. The outlet 115 faces the bearing surface 34, and the water outlet pipe 114 is placed on the bearing surface 34. Specifically, the width direction of the jet cooling component 1 refers to the direction towards which the outlet 115 in the jet cooling component 1 faces. The width of the jet cooling component 1 is smaller than the width of the housing 3 to be cooled, so that a sinking structure is formed between the side of the jet cooling component 1 provided with the outlet 115 and the housing 3 to be cooled. The bearing surface 34 is the bottom surface of the sinking structure. After the water outlet pipe 114 is connected to the outlet 115 of the jet cooling component 1, it is placed on the bearing surface 34. With such a setting, the water outlet pipe 114 does not need to be provided with a support structure and can be directly placed on the bearing surface 34, simplifying the structure. That is to say, the sinking structure can make the outlet 115 of the jet cooling component 1 closer to the bottom of the cooling cavity, so that the jet working fluid of the jet can flow back into the water outlet pipe 114 better and reduce the accumulation of the jet working fluid.

[0076] In some embodiments, it further includes a buckle 33 for limiting the water outlet pipe 114. The buckle 33 is used to fix the water outlet pipe 114. When the air-cooled heat dissipation fins 72 are also arranged on the housing 3 to be cooled, the buckle 33 fixes the water outlet pipe 114, so that there is a certain distance between the water outlet pipe 114 and the air-cooled heat dissipation fins 72, avoiding the position of the water outlet pipe 114 being too close to the air-cooled heat dissipation fins 72 and reducing its influence on the heat dissipation effect. The buckle 33 is installed on the bearing surface 34. The buckle 33 is provided with a card slot, and the water outlet pipe 114 is detachably connected to the card slot, which is convenient for assembly and beneficial to disassembly and maintenance.

[0077] In some embodiments, the housing 3 to be cooled includes a housing body 31 and a heat conducting member 32. The heat conducting member 32 is mounted on the housing body 31 and is configured to transfer the heat of the heating element 100 to the housing body 31; alternatively, the heat conducting member 32 penetrates through the housing body 31 and then connects to the jet cooling member 1. Specifically, the heat conducting member 32 can be fixedly provided on the housing body 31, or the heat conducting member 32 can merely be in contact connection with the housing body 31. The heat conducting member 32 is configured to transfer the heat of the heating element 100 to the housing body 31 or directly to the jet cooling member 1.

[0078] In some embodiments, the heating element 100 includes a first heating element 101 and a second heating element 102. The power of the first heating element 101 is greater than that of the second heating element 102, that is, the heat generation amount of the first heating element 101 is greater than that of the second heating element 102. The heat conducting member 32 includes a first heat conducting member 321 connected to the first heating element 101 and a second heat conducting member 322 connected to the second heating element 102. Since the heat generation amount of the first heating element 101 is greater than that of the second heating element 102, therefore, the heat conduction effect of the first heating element 101 needs to be better than that of the second heating element 102.

[0079] In some embodiments, the first heat conducting member 321 is a heat pipe filled with a heat conducting medium. One end of the heat pipe is connected to the first heating element 101, and the other end is connected to the housing body 31. Specifically, the first heating element 101 employs a cylindrical heat pipe. A heat pipe is a highly efficient heat transfer element, whose thermal conductivity is hundreds or even thousands of times higher than that of metals, and has characteristics such as good temperature uniformity, adjustable heat flux density, and reversible heat transfer direction. Since the heat transfer coefficient of the heat pipe is much higher than the thermal conductivity of metals, it can efficiently conduct heat. The other end of the heat pipe is connected to the housing 3 to be cooled by welding to transfer the heat of the first heating element 101 to the housing 3 to be cooled. The heat pipe is filled with a heat conducting medium, and the heat conducting medium can be a material with good heat conduction effect such as thermal grease. The heat generated when the heating element 100 operates is transferred to the heat pipe through the thermal grease, and then transferred to the housing 3 to be cooled through the heat pipe.

[0080] In some embodiments, please refer to Figure 5 , a through hole 311 is provided on the housing body 31. The first heating element 101 can be fixed through the through hole 311, or the first heating element 101 can contact the jet cooling member 1 after passing through the through hole 311, so that the heat of the heating element 100 can be directly transferred to the jet cooling member 1. Specifically, the top surface of the first heating element 101 is connected to the through hole 311 of the housing 3 to be cooled by welding to ensure heat conduction, and the other end contacts the electrical component through a heat conducting medium such as thermal grease.

[0081] In some embodiments, a heat conduction groove 116 is provided on the outer side of one side of the jet cooling component 1 close to the housing body 31. Specifically, the heat conduction groove 116 can be formed by the outer side of the bottom of the jet step 111. With such a setting, on the one hand, it is convenient to form the jet step 111, and the structural thickness of the jet cooling component 1 for forming the jet step 111 can be reduced, thereby improving the heat conduction efficiency. The first heat conduction component 321 passes through the through hole 311 and is then placed into the heat conduction groove 116, and the outer side wall of the first heat conduction component 321 fits with the inner side wall of the through hole 311, so that the first heat conduction component 321 can not only be fixed conveniently, but also transfer a part of the heat to the housing 3 to be cooled. Of course, in order to better ensure the integrity of the housing 3 to be cooled, the position of the pipe through hole can also be replaced with an installation groove, that is, no pipe through hole is opened on the housing 3 to be cooled, and the heat pipe is installed in the installation groove by using the protrusion of the installation groove relative to the surface of the housing 3 to be cooled, and the outer surface of the installation groove is placed into the heat conduction groove 116, which can avoid opening a pipe through hole on the housing 3 to be cooled and improve the sealing performance of the housing 3 to be cooled.

[0082] In some embodiments, the second heat conduction component 322 is a heat conduction metal block provided on the housing body 31, and the heat conduction metal block is in fitting connection with the second heating element 102; specifically, a heat conduction pad can also be provided between the second heat conduction component 322 and the heating element 100, and the heat emitted by the second heating element 102 is conducted to the second heat conduction component 322 through the contact between the heat conduction pad and the surface of the second heating element 102. That is to say, the heat generated by the first heating element 101 is transferred from one end of the heat pipe to the position where the through hole 311 contacts the other end of the heat pipe, and the heat generated by the second heating element 102 is transferred to the housing 3 to be cooled through the heat conduction metal block; the thickness of the base of the housing 3 to be cooled is 5.5 - 6.5 mm, and the heat conduction effect is good.

[0083] In some embodiments, the cross-sectional dimension of the first heat conduction component 321 is larger than the cross-sectional dimension of the first heating element 101, so that the heat conduction medium at one end of the first heat conduction component 321 covers the first heating element 101, that is, the bottom surface of the heat pipe can completely cover the top of the heating element 100, ensuring that as much heat as possible dissipated by the heating element 100 is transferred into the heat conduction medium. The heat conduction medium at the other end of the first heat conduction component 321 is in contact connection with the bottom surface of the heat conduction groove 116; specifically, the sizes of the top surface and the bottom surface of the heat pipe can both be larger than the size of the heating element 100, improving the heat exchange efficiency.

[0084] In some embodiments, the jet cooling component 1 includes a jet cooling main body 11 and a jet cooling cover plate 12. The jet cooling cover plate 12 is installed on the jet cooling main body 11. The cooling cavity is located inside the jet cooling main body 11. The jet nozzle 2 is installed on the jet cooling cover plate 12. The jet cooling main body 11 and the jet cooling cover plate 12 are detachably connected. Through the split design of the jet cooling main body 11 and the jet cooling cover plate 12, the disassembly and assembly of the jet cooling main body 11 and the jet cooling cover plate 12 can be facilitated, and the installation of the jet nozzle 2 is also more convenient. Of course, the jet cooling component 1 can also be an integral structure, that is, the jet cooling main body 11 and the jet cooling cover plate 12 can also be fixed by welding, with higher strength.

[0085] In some embodiments, a sealing component is further included. The sealing component is located between the jet cooling main body 11 and the jet cooling cover plate 12. A sealing groove 117 for installing the sealing component is provided on the end face of the jet cooling main body 11. The sealing groove 117 is arranged around the cooling cavity. The sealing component can be a sealing ring, such as a rubber ring. Specifically, a sealing groove 117 for placing the sealing ring is formed at the top of the jet cooling main body 11, and a number of threaded holes are also provided at the top of the jet cooling main body 11. For example, one threaded hole is provided at each of the four corners of the jet cooling main body 11. The jet cooling cover plate 12 is fixed on the jet cooling main body 11 by bolts and then sealed by the sealing ring to prevent the jet working medium from leaking.

[0086] In some embodiments, please refer to Figure 6, further comprising a flow supply and impact assembly 4 for supplying a jet working fluid to the jet nozzle 2. The flow supply and impact assembly 4 includes a medium pipeline 41, a jet working fluid box 42, liquid cooling fins 43, and a power component 44 connected in the medium pipeline 41. The jet working fluid box 42 is used to store the jet working fluid. The liquid cooling fins 43 are for the jet working fluid to flow through and dissipate heat. The power component 44 is used to provide power for the flow of the jet working fluid. Both the inlet and outlet 115 of the medium pipeline 41 are connected to the jet cooling component 1. With the above arrangement, by providing the flow supply and impact assembly 4, the flow supply and impact assembly 4 is used to supply the jet working fluid to the jet nozzle 2. At the same time, the flow supply and impact assembly 4 includes a medium pipeline 41, a jet working fluid box 42, liquid cooling fins 43, and a power component 44. The jet working fluid box 42, liquid cooling fins 43, and power component 44 are all connected in the medium pipeline 41. Specifically, the jet working fluid box 42 is used to store the jet working fluid, that is, the jet working fluid is stored in the jet working fluid box 42. Through the medium pipeline 41, the inflow or outflow of the jet working fluid into or out of the jet working fluid box 42 is realized. Specifically, one end of the medium pipeline 41 connected to the jet working fluid box 42 is connected to the water inlet pipe 113, and the other end is connected to the water outlet pipe 114. Through the settings of the medium pipeline 41, the water inlet pipe 113, and the water outlet pipe 114, a circulation loop is formed to realize the circulating flow of the jet working fluid between the jet cooling component 1 and the jet working fluid box 42. Then, the liquid cooling fins 43 and the power component 44 can be installed in the circulation loop. A number of fins are provided on the liquid cooling fins 43, and the jet working fluid flows through the fins to dissipate heat from the jet working fluid. The power component 44 is used to provide power for the flow of the jet working fluid to ensure the circulating flow of the jet working fluid in the circulation loop, so as to ensure that the jet working fluid absorbs heat in the jet cooling component 1 and dissipates heat in the liquid cooling fins 43, and continuously supply the jet cooling component 1 with a jet working fluid at a lower temperature.

[0087] In some embodiments, a flow supply housing 5 is further included. The flow supply and impact assembly 4 is disposed within the flow supply housing 5. The flow supply housing 5 is disposed in close contact with the housing to be cooled 3. A number of ventilation openings 51 are provided on the side wall of the flow supply housing 5, and the ventilation openings 51 face the first fan 45 to allow air to circulate and ensure the normal operation of the first fan 45. Specifically, threaded holes can be provided on the flow supply housing 5 and connected to the housing to be cooled 3 through bolts.

[0088] In some embodiments, between the flow supply housing 5 and the housing to be cooled 3, and between the jet cooling component 1 and the housing to be cooled 3, a quick-release structure can be adopted for connection, so that the flow supply housing 5 and the jet cooling component 1 can be easily separated from the housing to be cooled 3, which is more convenient to use, has a wide application range, and flexible installation positions.

[0089] In some embodiments, please refer to Figure 6, a phase change heat dissipation material component 421 is further provided in the jet working fluid box body 42. The phase change heat dissipation material component 421 is used to absorb the heat of the jet working fluid when the temperature of the jet working fluid is higher than the first temperature threshold. Specifically, when the temperature of the jet working fluid exceeds the first temperature threshold, the setting of the first temperature threshold is related to the temperature threshold of the heating element 100. The temperature of the phase change heat dissipation material component 421 rises and undergoes a phase change, so that the temperature of the water outlet of the jet working fluid box body 42 decreases, which can effectively enhance heat dissipation and prevent the temperature of the heating element 100 from exceeding the limit. Further, the phase change heat dissipation material component 421 can be divided into three types according to its changes before and after phase change: solid-liquid type, gas-liquid type, and solid-gas type. For the reliability and safety of use, in this example, a solid-liquid organic phase change heat dissipation material component 421 is used as the filling. In this example, a lauric acid-stearic acid eutectic is used as the phase change heat dissipation material component 421. Of course, other types of phase change heat dissipation material components 421 can also be selected. For example, the phase change temperature of the phase change heat dissipation material component 421 is between 62-65 °C, or other required temperatures. Further, the phase change heat dissipation material component 421 can be arranged at the bottom of the jet working fluid box body 42. When the temperature of the jet working fluid at the outlet 115 of the jet working fluid box body 42 is too high, the phase change material reaches the phase change temperature point, absorbs heat and undergoes a phase change, so that the temperature of the jet working fluid drops rapidly, preventing the temperature of the heating element 100 from being too high and causing overheating.

[0090] In some embodiments, the fluid supply impact assembly 4 further includes a first fan 45 and a heating component 46. The first fan 45 is arranged near the liquid cooling heat dissipation fins 43 and is used to cool the liquid cooling heat dissipation fins 43; the heating component 46 is installed in the jet working fluid box body 42 and is used to heat the jet working fluid; both the first fan 45 and the heating component 46 are installed in the fluid supply housing 5. The heating component 46 can be a heating rod. When the cooling temperature in the jet working fluid box body 42 is too high, it can be cooled by the first fan 45. When the cooling temperature in the jet working fluid box body 42 is too low, it can be heated by the heating component 46.

[0091] In a specific embodiment, the fluid supply impact assembly 4 includes a jet nozzle 2, a medium pipeline 41, flow channel heat dissipation fins, a power component 44, a first fan 45, and a jet working fluid box 42; the jet nozzle 2 is fixed on the threaded hole of the jet cooling cover plate 12 through the thread thereon, and the position of the jet nozzle 2 is directly opposite to the jet step 111. The liquid in the jet nozzle 2 enters the jet nozzle 2 through the water inlet pipe 113, then passes through the water outlet pipe 114, flows through the medium pipeline 41 where the liquid-cooling heat dissipation fins 43 are located, enters the jet working fluid box 42 after being cooled by the first fan 45; the water entering the jet working fluid box 42 is transported to the water inlet pipe 113 through the power component 44 via the medium pipeline 41 for repeated circulation; the connection interfaces between the medium pipeline 41 and the water inlet pipe 113 and the water outlet pipe 114 can adopt threaded pipes, and the medium pipeline 41 is fixed to the fluid supply housing 5 through threads, playing a role of sealing and connection; since the water inlet pipe 113 and the water outlet pipe 114 are exposed to the outside, the materials of the water inlet pipe 113 and the water outlet pipe 114 are selected as stainless steel materials that are corrosion-resistant and have a certain strength, such as aluminum pipes or copper pipes, to ensure that they have a high thermal conductivity coefficient, which is beneficial to the heat dissipation of the jet working fluid; the outer sides of the water inlet pipe 113 and the water outlet pipe 114 are also sprayed with a super-hydrophobic coating to avoid rainwater residue on the water inlet pipe 113 and the water outlet pipe 114 and extend the service life of the water inlet pipe 113 and the water outlet pipe 114; the flow channel heat dissipation fins can be welded on the medium pipeline 41, and the material of the flow channel heat dissipation fins can be aluminum. The height of the connection between the medium pipeline 41 and the jet working fluid box 42 should be lower than the root height of the liquid-cooling heat dissipation fins 43 to ensure the normal reflux of the liquid working fluid; the power component 44 is installed in the medium pipeline 41. After the jet working fluid is pumped into the power component 44 from the medium pipeline 41 for pressurization, it flows out of the medium pipeline 41 into the water inlet pipe 113, then flows to the jet nozzle 2, and the heat transferred from the heating element 100 is carried away after jetting, and then returns through the water outlet pipe 114, repeating like this.

[0092] In some embodiments, please refer to Figure 9 , and it further includes a controller 6 and a temperature detection component 47. The temperature detection component 47 is arranged on the medium pipeline 41 and is used to obtain the medium temperature of the jet working fluid in the jet working fluid box 42; the controller 6 is connected to the power component 44, the heating component 46, the first fan 45, and the temperature detection component 47; the controller 6 is used for:

[0093] Obtaining the medium temperature of the jet working fluid in the jet working fluid box 42;

[0094] When the medium temperature is higher than the first temperature threshold, controlling the rotational speed of the first fan 45 to increase to reduce the temperature of the jet working fluid;

[0095] When the medium temperature is lower than the second temperature threshold, control the heating component 46 to start, raise the temperature of the jet working medium, and when the medium temperature is higher than the third temperature threshold, control the heating component 46 to turn off, where the third temperature threshold is greater than the second temperature threshold.

[0096] When the medium temperature is lower than the second temperature threshold and the electronic device is not started, control the power component 44 to run at a low speed.

[0097] Specifically, when the electronic device operates at a low temperature, for example, when the ambient temperature is below 0°C, a heating component 46 is added inside the jet working medium box 42; when the temperature detection component 47 detects that the temperature of the jet working medium is lower than the second temperature threshold, turn on the heating component 46 to raise the temperature of the jet working medium in the jet working medium box 42, and when the temperature of the jet working medium is higher than the third temperature threshold, turn off the heating component 46. At the same time, when the temperature is low, when the temperature detection component 47 detects that the temperature of the jet working medium is lower than the second temperature threshold, even if the electronic device is not operating, keep the power component 44 continuously working to ensure the flow of the jet working medium in the medium pipeline 41, the water inlet pipe 113, and the return pipe, avoid freezing of the liquid in the medium pipeline 41, the water inlet pipe 113, and the return pipe, and at the same time ensure that the temperature of the heating element 100 will not be too low, ensure that the electronic device can be turned on immediately at any time without a warm-up time; also avoid damage to the heating element 100 due to too low temperature; when the ambient temperature is lower than the third temperature threshold, the first fan 45 stops working; when the temperature detection device detects that the temperature of the jet working medium is greater than the third temperature threshold, the first fan 45 starts working.

[0098] In a specific embodiment, if the electronic device is applied in a weather with a relatively low temperature, 2 - 4 heating rods can be added inside the jet working fluid box 42, and a temperature detection component 47 can be added inside the jet working fluid box 42. When the temperature detection component 47 detects that the water temperature at the outlet 115 of the jet working fluid box 42 is less than or equal to the second temperature threshold, for example, 3°C, the heating rods are turned on. In this case, even if the electronic device is not operating temporarily, the power component 44 remains turned on to ensure that the liquid in the circulation pipeline can flow, preventing the liquid in the circulation pipeline from freezing, which may cause the jet cooling system to malfunction and even damage the circulation pipeline; this method can also ensure that the temperature of the heating element 100 does not become too low, avoiding the heating element 100 from being unable to start due to low temperature, enabling the electronic device to ensure its startup speed even at low temperatures without the need for warm-up; at the same time, it also avoids the problem of the heating element 100 being damaged due to low temperature. When the temperature detection component 47 detects that the water temperature at the outlet 115 of the jet working fluid box 42 is greater than the third temperature threshold, for example, 10 - 12°C, the operation of the heating rods is stopped. If the temperature detection component 47 detects that the water temperature at the outlet 115 of the jet working fluid box 42 is less than the second temperature threshold, the operation of the first fan 45 is stopped to prevent the airflow from the first fan 45 from causing the water flow in the circulation pipeline to freeze; if during the period when the first fan 45 is stopped, the temperature detection component 47 detects that the temperature exceeds the third temperature threshold, the first fan 45 is restarted.

[0099] In some embodiments, an air-cooling assembly 7 is further included. The air-cooling assembly 7 is disposed close to the second heating element 102. The air-cooling assembly 7 includes a second fan 71 and air-cooling fins 72. The air-cooling fins 72 are used to be mounted on the housing 3 to be cooled and are located beside the jet cooling component 1; the second fan 71 is disposed close to the air-cooling fins 72 and is used to provide air flow for the air-cooling fins 72; the second fan 71 is mounted on the base of the housing 3 to be cooled, and the bottom of the second fan 71 is flush with the bottom of the air-cooling fins 72 to ensure that the air flow generated by the second fan 71 smoothly enters the air-cooling fins 72; specifically, the jet cooling component 1 can be disposed between two adjacent air-cooling fins 72, and the width of the air-cooling fins 72 can be the same as the width of the housing 3 to be cooled, increasing the contact area between the air-cooling fins 72 and the housing 3 to be cooled, thereby improving the heat exchange efficiency between the air-cooling fins 72 and the housing 3 to be cooled. Since the width of the jet cooling component 1 is less than the width of the housing 3 to be cooled, as Figure 1As shown, a sinking structure is formed between the jet cooling component 1 and the two adjacent air-cooled heat dissipation fins 72; further, the water outlet pipe 114 extends from the outlet 115 of the jet cooling component 1 to the side of the air-cooled heat dissipation fin 72 in the air flow direction, and then extends to the fluid supply housing 5; the outlet 115 of the jet cooling component 1 is arranged at the bottom of the side wall, so that the water outlet pipe 114 is attached to the surface of the housing 3 to be cooled, which not only facilitates the installation of the water outlet pipe 114, but also can reduce the blockage of the air flow in the air-cooled heat dissipation fin 72 by the water outlet pipe 114 and ensure the air-cooled heat dissipation effect; through the above settings, the heat dissipation system becomes an air-cooled - jet impingement combined heat dissipation system that can be used outdoors. Specifically, the sinking height of the sinking structure is 3 - 4 mm, and the water outlet pipes 114 are arranged along the sinking structure and fixed by the buckle 33 to ensure that the water outlet pipes 114 are 15 - 25 mm away from the air-cooled heat dissipation fins 72, so as to reduce the blockage of the air flow in the heat dissipation fins by the water outlet pipes 114 and thus reduce its influence on the heat dissipation effect.

[0100] In some embodiments, please refer to Figure 7 , an air-cooled deflector 73 is installed on the air-cooled heat dissipation fin 72, and the second fan 71 is located on the side of the air-cooled heat dissipation fin 72 where the air-cooled deflector 73 is provided; specifically, there is an air-cooled deflector 73 on the upper part of the chassis fin for guiding the air flow and enhancing the heat dissipation effect of the fan. Of course, the second fan 71 can also be connected to the controller 6, and the power of the second fan 71 can be controlled simultaneously according to the temperature of the jet working fluid to achieve the mutual cooperation of air-cooled cooling and jet cooling.

[0101] The above electronic device is cooled by a heat dissipation system that combines air cooling and jet impingement cooling. The high-power consumption heating element 100 is cooled by jet impingement, and the remaining low-power consumption heating elements 100 are cooled by air cooling. By this method, not only the heat dissipation ability of the electronic device is enhanced, but also compared with other jet impingement cooling methods, the requirements for the jet working fluid are lower and the safety is higher. Since the liquid working fluid does not contact the heating element 100 in the housing 3 to be cooled, it is beneficial for later disassembly and maintenance. At the same time, this heat dissipation system can be used for outdoor servers. Under the condition of high ambient temperature outdoors, jet impingement cooling can effectively improve the heat transfer performance of the server. Combined with the phase change material in the jet working fluid box 42, in case of abnormal conditions, it can improve the problem that the heating element 100 is damaged due to overheating caused by abnormal conditions, and can ensure the rapid low-temperature startup of the server in a low-temperature environment to avoid the damage of the heating element 100 due to too low outdoor temperature.

[0102] The heat dissipation system enhances the heat dissipation capacity of electronic devices through jet impingement cooling, and combines air cooling with jet impingement cooling, avoiding the influence on the layout of internal electronic components of electronic devices, which is beneficial to the design and manufacture of electronic devices; the jet impingement liquid does not come into contact with the internal electronic components of the electronic device, greatly improving the reliability of the electronic device and facilitating the disassembly and maintenance of the electronic device in the later stage; this type of electronic device can be used in outdoor environments. Through the preset heat dissipation system logic, the heat dissipation of the electronic device can be enhanced at high ambient temperatures; at low ambient temperatures, the normal operation of the jet system can be ensured through the heating device and low-temperature circulation logic, while ensuring that the heating elements 100 and the like will not be damaged due to being too cold, so that the temperature of the heating elements 100 is maintained at the normal storage or operating temperature.

[0103] In addition to the above heat dissipation system, the present invention also provides an electronic device including the above heat dissipation system. For the structures of other parts of this electronic device, please refer to the related technologies and will not be elaborated herein.
