[0036] The heat dissipation system provided by the present invention has the following beneficial effects: through the arrangement of the jet cooling component, a cooling chamber is arranged inside the jet cooling component, and the arrangement of the cooling chamber can provide space for the heat exchange of the jet working medium, and the jet cooling component is in contact with and connected to the shell to be cooled, specifically, the outer side of the bottom of the cooling chamber of the jet cooling component is in contact with the shell to be cooled, and then a heat-conducting structure is formed by the bottom of the cooling chamber of the jet cooling component, and the heat from the shell to be cooled is transferred to the inner side of the bottom of the cooling chamber through the outer side of the bottom of the cooling chamber of the jet cooling component. Since the heat of the shell to be cooled has been transferred to the jet cooling component, only It is sufficient to cool the jet cooling component. 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 conducive to 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 heating element by the jet cooling component. Regarding the heat transfer between the heating element and the shell to be cooled, a heat-conducting component can be provided between the heating element and the shell to be cooled, or a heat-conducting component can be provided, and the heat-conducting component is used to penetrate the shell to be cooled and then contact the jet cooling component. The heat-conducting component penetrates the shell to be cooled and then contacts the jet cooling component. In the process of cooling the shell, it can also contact with the shell to be cooled, so that part of the heat emitted from the heating element is transferred to the shell to be cooled, and part of it can be directly transferred to the jet cooling component, which can further improve the heat dissipation efficiency of the jet cooling component on 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.

When the heating element needs maintenance, the application environment of the heating element is dry and there is not much liquid interference, which is convenient for maintenance. In addition, the 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 achieving the cooling of the shell to be cooled, and then achieving the cooling effect of 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 space inside 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 has low requirements on the type of jet working fluid, because the jet working fluid does not need to contact the heating element, which is beneficial to reducing costs and having higher safety. At the same time, because the heating element does not need to contact the jet working fluid, the disassembly, assembly and maintenance of the shell to be cooled are more convenient.

At the same time, the flow impact assembly includes a medium pipeline, a jet working fluid box, a liquid-cooled heat sink and a power component. The jet working fluid box, the liquid-cooled heat sink and the power component are all connected to the medium pipeline. Specifically, the jet working fluid box is used to hold the jet working fluid, that is, the jet working fluid is stored in the jet working fluid box, and the jet working fluid flows into or out of the jet working fluid box through the medium pipeline. Specifically, the medium pipeline connected to the jet working fluid box is connected to the water inlet pipe at one end and the water outlet pipe at the other end. , a circulation loop is formed by setting up a medium pipeline, a water inlet pipe and a water outlet pipe, so as to realize the circulation flow of the jet working fluid between the jet cooling component and the jet working fluid box, and then the liquid cooling heat sink fins and the power component can be installed in the circulation loop. A plurality of fins are provided on the liquid cooling heat sink fins, and the jet working fluid flows through the fins for the jet working fluid to dissipate heat. The power component is used to provide power for the flow of the jet working fluid, so as to ensure that the jet working fluid circulates in the circulation loop, thereby ensuring that the jet working fluid absorbs heat in the jet cooling component and dissipates heat in the liquid cooling heat sink fins, so as to continuously supply the jet cooling component with a jet working fluid with a lower temperature.

[0059] The core of the present invention is to provide a heat dissipation system and electronic equipment, which have reasonable layout, convenient assembly and disassembly, wide application range and 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 is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0061] In jet impingement heat transfer, gas or liquid is directly sprayed onto the surface to be cooled or heated through a circular or slit-type jet nozzle 2 under pressure, so that the wall area impacted produces a strong heat transfer effect. This method is a very efficient method of enhancing heat transfer. Its characteristics are that the fluid can directly impact the surface, the process is shortened, and a thinner boundary layer is formed near the stagnation point. The shortening of the boundary layer effectively enhances the heat exchange efficiency, especially in the part facing 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] Servers, especially edge servers, cannot dissipate heat in time due to the high power consumption of the heating element 100 and the harsh working environment, causing the temperature of the heating element 100 to be too high. It is necessary to further find ways to improve the heat dissipation capacity of the server; jet impact cooling is a very efficient heat exchange method. Currently, jet cooling is mostly jet fluid contact cooling, which has high requirements for the jet fluid and is not convenient for subsequent server maintenance; at the same time, it also complicates the internal design layout of the server; currently, jet cooling servers are mostly used in indoor environments such as data centers, and there is a lack of jet cooling methods that can be used outdoors to enhance heat dissipation and avoid overcooling of the heating element 100.

[0063] In this implementation, please refer to Figure 1 , Figure 4 and Figure 6 , the cooling system includes:

[0064] The jet cooling component 1 has a cooling cavity inside, and the outer side of the 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 side of the bottom of the cooling cavity to the inner side of the bottom of the cooling cavity, and a heating element 100 is arranged in the shell 3 to be cooled; specifically, the heating element 100 is a heating element 100 in an electronic device, generally including a CPU (Central Processing Unit, central processing unit), a GPU (Graphics Processing Unit, graphics processing unit) module and other high-power heating elements 100 and other low-power heating elements 100;

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

[0066] Specifically, the jet cooling component 1 can be formed by machining or casting, and the cooling cavity can be set at the center of the jet cooling component 1 to ensure the stability and cooling uniformity of the jet cooling component 1. The bottom outer side 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 be better fitted with the shell 3 to be cooled, thereby improving the efficiency of heat transfer; the jet nozzle 2 is installed on the jet cooling component 1, and the jet nozzle 2 is arranged toward the cooling cavity. Since the distance between the bottom of the cooling cavity and the shell 3 to be cooled is the shortest, the jet nozzle 2 is directed toward the bottom inner side of the cooling cavity, which can improve the cooling efficiency of the bottom of the cooling cavity, thereby improving 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] The heat dissipation system, through the setting of the jet cooling component 1, the jet cooling component 1 is provided with a cooling chamber inside, and the setting of the cooling chamber can provide space for the heat exchange of the jet working medium, the jet cooling component 1 is in contact with the shell 3 to be cooled, specifically, the outer side of the bottom of the cooling chamber of the jet cooling component 1 is in contact with the shell 3 to be cooled, and then a heat-conducting structure is formed by the bottom of the cooling chamber of the jet cooling component 1, and the heat from the shell 3 to be cooled is transferred to the inner side of the bottom of the cooling chamber through the outer side of the bottom of the cooling chamber 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, it is only necessary to cool the jet cooling component 1. 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, and there is a heat exchanger between the shell 3 to be cooled and the heating element 100. The temperature difference is conducive to the heat dissipation of the heating element 100 to continue to be transferred to the shell body 3 to be cooled, thereby realizing the continuous heat dissipation of the heating element 100 by the jet cooling component 1; regarding the heat transfer between the heating element 100 and the shell body 3 to be cooled, a heat-conducting component 32 can be provided between the heating element 100 and the shell body 3 to be cooled, or a heat-conducting component 32 can be provided, and the heat-conducting component 32 penetrates the shell body 3 to be cooled and then contacts with the jet cooling component 1, and the heat-conducting component 32 can also contact with the shell body 3 to be cooled during the process of penetrating the shell body 3 to be cooled, so that part of the heat dissipated in the heating element 100 is transferred to the shell body 3 to be cooled, and part of it 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 utilizing 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, it not only fully utilizes the high efficiency of jet impact cooling, but also avoids the influence of the jet working fluid on the heating element 100, thereby reducing the requirements for the type of jet working fluid. There is no need to consider the influence of the jet working fluid on factors such as corrosion and insulation of the heating element 100, and the contact between the jet working fluid and the heating element 100 is avoided. When the heating element 100 needs maintenance, the application environment of the heating element 100 is dry, without too much liquid interference, and maintenance is convenient.

[0069] Furthermore, the jet nozzle 2 is used to provide a jet working fluid for the jet cooling component 1, and the jet cooling component 1 is cooled by the jet working fluid, thereby achieving the cooling of the shell 3 to be cooled, and then achieving the cooling effect of 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 space inside the shell 3 to be cooled, which is convenient for arrangement 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 on the type of jet working fluid, since the jet working fluid does not need to contact the heating element 100, which is beneficial to reducing costs and having higher safety. At the same time, since the heating element 100 does not need to contact the jet working fluid, the disassembly, assembly and maintenance of the shell 3 to be cooled are more convenient. Moreover, the heat dissipation system has a reasonable structural layout, which is beneficial to miniaturized design, does not need to occupy the internal space of the shell 3 to be cooled, is beneficial to the layout of the shell 3 to be cooled, has low manufacturing cost, and has higher heat dissipation efficiency.

[0071] In some embodiments, please refer to Figure 2 and Figure 3 A jet step 111 is provided inside the cooling chamber on one side close to the shell 3 to be cooled, and the jet step 111 is conducive to the concentration of heat and ensures the effect of jet impact cooling; the jet nozzle 2 is arranged toward the jet step 111, and the jet nozzle 2 can be directly opposite to the center of the jet step 111. By setting the jet step 111, the distance between the jet nozzle 2 and the jet step 111 can be reduced, and the jet working medium can be more fully sprayed onto the jet step 111 to improve the cooling effect; the jet step 111 is located at the bottom of the cooling chamber, and the position of the jet step 111 corresponds to the position of the heating element 100 with a larger heat generation in the cooling component, and the jet step 111 extends in the direction away from the component to be cooled, that is, the jet step 111 extends from the bottom of the cooling chamber to the middle of the cooling chamber, so that better heat conduction and heat dissipation can be carried out between the jet step 111 and the heating element 100 with a larger heat generation.

[0072] In some embodiments, a guide groove 112 is provided between the jet step 111 and the side wall of the jet cooling component 1. Specifically, the guide groove 112 can surround the circumference of the jet step 111, and the jet working fluid sprayed onto the jet step 111 by the jet nozzle 2 can flow into the guide groove 112 through the jet step 111, so as to facilitate the collection of the jet working fluid and enable the jet working fluid to flow out smoothly from the outlet 115 of the jet cooling component 1.

[0073] In some embodiments, the jet cooling component 1 is also connected to a water inlet pipe 113 and a water outlet pipe 114. The water inlet pipe 113 is connected to the jet nozzle 2, so that the water inlet pipe 113 can supply the jet working medium to the cooling chamber 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, so that the jet working medium in the cooling chamber of the jet cooling component 1 can flow along the outlet 115 to the water outlet pipe 114. Specifically, the outlet 115 is arranged at the bottom of the side wall of the jet cooling component 1, so that the jet working medium can flow out of the cooling chamber under the action of gravity. Furthermore, the inlet and outlet 115 of the jet cooling component 1 are both threaded holes, and the jet nozzle 2 and the water outlet pipe 114 are respectively fixed to the jet cooling component 1 through threaded holes, which is convenient for installation and has a good sealing effect.

[0074] In some embodiments, the guide groove 112 surrounds the circumference of the jet step 111, and the bottom surface of the guide groove 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 the guide groove 112 is located at the outlet 115 of the cooling chamber. Such a configuration enables the jet working medium to flow along the guide groove 112 to the outlet 115 and enter the water outlet pipe 114. The highest position of the guide groove 112 should also be lower than the height of the jet step 111 to prevent the liquid in the guide groove 112 from submerging the jet step 111; further, the inclination angle of the bottom surface of the cooling chamber is 5-10°, and the inside of the cooling chamber, except for the surface of the jet step 111, is sprayed with a hydrophobic coating with good hydrophobic effect. The material of the hydrophobic coating can be selected as needed, and the bottom surface of the cooling chamber and the super-hydrophobic coating are conducive to the water sprayed from the jet nozzle 2 to flow back to 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 shell 3 to be cooled, so as to form a bearing surface 34 on the surface of the shell 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 toward which the outlet 115 in the jet cooling component 1 faces, and the width of the jet cooling component 1 is smaller than the width of the shell 3 to be cooled, so that a side of the jet cooling component 1 with the outlet 115 is provided, and a sinking structure is formed between the shell 3 to be cooled, and 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. In this way, the water outlet pipe 114 does not need to be provided with a supporting structure, and can be directly placed on the bearing surface 34, thereby simplifying the structure; that is, the sinking structure can make the outlet 115 of the jet cooling component 1 closer to the bottom of the cooling chamber, so that the jet working fluid of the jet can better flow back into the water outlet pipe 114, thereby reducing the accumulation of the jet working fluid.

[0076] In some embodiments, a buckle 33 for limiting the water outlet pipe 114 is also included. The buckle 33 is used to fix the water outlet pipe 114. When air-cooled heat sink fins 72 are also arranged on the shell 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 sink fins 72 to avoid the water outlet pipe 114 being too close to the air-cooled heat sink fins 72, thereby reducing its influence on the heat dissipation effect. The buckle 33 is installed on the bearing surface 34, and a slot is provided on the buckle 33. The water outlet pipe 114 is detachably connected to the slot, which is convenient for assembly and facilitates disassembly and maintenance.

[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 the power of the second heating element 102, that is, the heat generated by the first heating element 101 is greater than the heat generated by the second heating element 102; the heat-conducting component 321 connected to the first heating element 101 and the second heat-conducting component 322 connected to the second heating element 102; since the heat generated by the first heating element 101 is greater than the heat generated by the second heating element 102, it is required that the heat conduction effect of the first heating element 101 is better than the heat conduction effect of the second heating element 102.

[0079] In some embodiments, the first heat-conducting component 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 shell body 31; specifically, the first heating element 101 adopts a cylindrical heat pipe, which is a high-efficiency heat transfer element, and its thermal conductivity is hundreds or even thousands of times higher than that of metal, and has the characteristics of 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 the metal, it can efficiently conduct heat, and the other end of the heat pipe is connected to the shell 3 to be cooled by welding, and the heat of the first heating element 101 is transferred to the shell 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 thermal conductivity such as thermal grease. The heat generated by the heating element 100 when working is transferred to the heat pipe through the thermal grease, and then transferred to the shell 3 to be cooled through the heat pipe.

The first heat conduction component 321 is inserted into the heat conduction groove 116 after passing through the through hole 311, and the outer wall of the first heat conduction component 321 is fitted with the inner wall of the through hole 311, so that the first heat conduction component 321 can not only be easily fixed, but also can transfer part of the heat to the shell 3 to be cooled. Of course, in order to better ensure the integrity of the shell 3 to be cooled, the position of the tube perforation can also be replaced by a mounting groove, that is, no tube perforation will be opened on the shell 3 to be cooled, and the mounting groove is used to protrude relative to the surface of the shell 3 to be cooled, and the heat pipe is installed in the mounting groove, and the outer surface of the mounting groove is placed in the heat conduction groove 116, which can avoid opening a tube perforation on the shell 3 to be cooled, thereby improving the sealing of the shell 3 to be cooled.

[0082] In some embodiments, the second heat-conducting component 322 is a heat-conducting metal block disposed on the shell body 31, and the heat-conducting metal block is connected to the second heating element 102 in a close fit; specifically, a heat-conducting pad can be further disposed between the second heat-conducting component 322 and the heating element 100, and the heat-conducting pad is in contact with the surface of the second heating element 102, so that the heat generated by the second heating element 102 is conducted to the second heat-conducting component 322. In other words, 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 shell 3 to be cooled through the heat-conducting metal block; the thickness of the base of the shell 3 to be cooled is 5.5-6.5 mm, and the heat conduction effect is good.

[0083] In some embodiments, the cross-sectional size of the first heat-conducting component 321 is larger than the cross-sectional size of the first heating element 101, so that the heat-conducting medium located at one end of the first heat-conducting 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 the heat emitted by the heating element 100 is transferred to the heat-conducting medium as much as possible, and the heat-conducting medium at the other end of the first heat-conducting component 321 is in contact with and connected to the bottom surface of the heat-conducting groove 116; specifically, the sizes of the top and bottom surfaces of the heat pipe can be larger than the sizes of the heating element 100, thereby improving the heat exchange efficiency.

[0085] In some embodiments, a sealing component is also included, which is located between the jet cooling 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 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 opened on the top of the jet cooling body 11, and a plurality of threaded holes are also provided on the top of the jet cooling body 11. For example, a threaded hole is provided at each of the four corners of the jet cooling body 11. The jet cooling cover plate 12 is fixed to the jet cooling body 11 by bolts, and then sealed by a sealing ring to prevent leakage of the jet working fluid.

[0086] In some embodiments, please refer to Figure 6, and also includes a flow supply impact component 4 for providing jet working fluid to the jet nozzle 2. The flow supply impact component 4 includes a medium pipeline 41 and a jet working fluid box 42, a liquid-cooled heat sink fin 43 and a power component 44 connected to the medium pipeline 41. The jet working fluid box 42 is used to contain the jet working fluid, the liquid-cooled heat sink fin 43 allows the jet working fluid to flow through and dissipate heat, and the power component 44 is used to provide power for the flow of the jet working fluid, and the inlet and outlet 115 of the medium pipeline 41 are both connected to the jet cooling component 1. The above-mentioned arrangement is provided by setting a flow impact assembly 4, which is used to provide a jet working fluid for the jet nozzle 2. At the same time, the flow impact assembly 4 includes a medium pipeline 41, a jet working fluid box 42, a liquid-cooled heat sink fin 43 and a power component 44. The jet working fluid box 42, the liquid-cooled heat sink fin 43 and the power component 44 are all connected to the medium pipeline 41. Specifically, the jet working fluid box 42 is used to contain the jet working fluid, that is, the jet working fluid is stored in the jet working fluid box 42, and the jet working fluid flows into or out of the jet working fluid box 42 through the medium pipeline 41. Specifically, the medium pipeline 41 connected to the jet working fluid box 42 is connected to the water inlet pipe 113 at one end and to the water outlet pipe 113 at the other end. The pipe 114 is connected, and a circulation loop is formed through the setting of the medium pipeline 41, the water inlet pipe 113 and the water outlet pipe 114, so as to realize the circulation flow of the jet working fluid between the jet cooling component 1 and the jet working fluid box 42, and then the liquid cooling heat dissipation fins 43 and the power component 44 are installed in the circulation loop. A plurality of fins are provided on the liquid cooling heat dissipation fins 43, and the jet working fluid flows through the fins for the jet working fluid to dissipate heat. The power component 44 is used to provide power for the flow of the jet working fluid, so as to ensure that the jet working fluid circulates in the circulation loop, thereby ensuring that the jet working fluid absorbs heat in the jet cooling component 1 and dissipates heat in the liquid cooling heat dissipation fins 43, so as to continuously supply the jet cooling component 1 with a jet working fluid with a lower temperature.

[0087] In some embodiments, it also includes a flow supply shell 5, in which the flow supply impact assembly 4 is arranged. The flow supply shell 5 is arranged in close contact with the shell 3 to be cooled. A plurality of vents 51 are provided on the side wall of the flow supply shell 5. The vents 51 are directly facing the first fan 45 to allow air circulation and ensure the normal use of the first fan 45. Specifically, threaded holes can be provided on the flow supply shell 5 to be connected to the shell 3 to be cooled by bolts.

[0088] In some embodiments, a quick-release structure can be used to connect the air supply shell 5 and the shell to be cooled 3, as well as the jet cooling component 1 and the shell to be cooled 3. The air supply shell 5 and the jet cooling component 1 can be easily separated from the shell to be cooled 3, which is more convenient to use, has a wide range of applications, and is flexible in installation position.

[0089] In some embodiments, please refer to Figure 6The jet working fluid box 42 is also provided with a phase change heat dissipation material component 421, which is used to undergo a phase change 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 a phase change occurs, so that the outlet temperature of the jet working fluid box 42 is reduced, which can effectively enhance the heat dissipation and avoid the temperature of the heating element 100. Overtemperature; further, the phase-change heat dissipation material component 421 can be divided into three types according to its changes before and after the 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 a filler. In this example, 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 set at the bottom of the jet working fluid box 42. When the temperature of the jet working fluid at the outlet 115 of the jet working fluid box 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, avoiding the overheating caused by the excessive temperature of the heating element 100.

[0090] In some embodiments, the flow impact assembly 4 also includes a first fan 45 and a heating component 46. The first fan 45 is arranged near the liquid-cooled heat sink fins 43 for cooling the liquid-cooled heat sink fins 43. The heating component 46 is installed in the jet working fluid box 42 for heating the jet working fluid. The first fan 45 and the heating component 46 are both installed in the flow shell 5. The heating component 46 can be a heating rod. When the cooling temperature in the jet working fluid box 42 is too high, the first fan 45 can be used to cool it down. When the cooling temperature in the jet working fluid box 42 is too low, the heating component 46 can be used to heat it up.

[0091] In a specific embodiment, the flow impact assembly 4 includes a jet nozzle 2, a medium pipeline 41, a flow channel heat dissipation fin, a power component 44, a first fan 45 and a jet working medium box 42; the jet nozzle 2 is fixed to the threaded hole of the jet cooling cover plate 12 through the thread thereon, and the position of the jet nozzle 2 is opposite to the jet step 111. The liquid of the jet in the jet nozzle 2 enters the jet nozzle 2 through the water inlet pipe 113, and then passes through the water outlet pipe 114 and flows through the medium pipeline where the liquid cooling heat dissipation fin 43 is located. 41, after being cooled by the first fan 45, enters the jet working medium box 42; the water entering the jet working medium box 42 passes through the power component 44, and is transported to the water inlet pipe 113 through the medium pipeline 41, and the cycle is repeated; the connection interface between the medium pipeline 41 and the water inlet pipe 113 and the water outlet pipe 114 can be a threaded pipe, and the medium pipeline 41 is fixed to the flow supply housing 5 through the thread, which plays a sealing and connecting role; since the water inlet pipe 113 and the water outlet pipe 114 are exposed to the outside, the water inlet pipe 113 and the water outlet pipe 114 are exposed to the outside, and ... The material of the water inlet pipe 113 and the outlet pipe 114 is selected from corrosion-resistant and strong stainless steel materials, such as aluminum tubes or copper tubes, to ensure that they have a high thermal conductivity, which is conducive to the heat dissipation of the jet working medium; the outer sides of the water inlet pipe 113 and the water outlet pipe 114 are also sprayed with a super-hydrophobic coating to prevent rainwater from remaining on the water inlet pipe 113 and the water outlet pipe 114, thereby extending 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 is It can be made of aluminum. The height of the connection between the medium pipeline 41 and the jet working medium box 42 should be lower than the root height of the liquid cooling fins 43 to ensure that the liquid working medium can reflux normally. The power component 44 is installed in the medium pipeline 41. The jet working medium is drawn into the power component 44 from the medium pipeline 41 and pressurized. It flows out of the medium pipeline 41 into the water inlet pipe 113, and then flows to the jet nozzle 2. The jet takes away the heat transferred from the heating element 100, and then flows back through the water outlet pipe 114, and repeats this process.

[0092] In some embodiments, please refer to Fig. 9 , further comprising a controller 6 and a temperature detection component 47, the temperature detection component 47 being arranged on the medium pipeline 41 and used to obtain the medium temperature of the jet working medium in the jet working medium 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 to:

[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, the speed of the first fan 45 is controlled to increase to reduce the temperature of the jet working fluid;

[0095] When the medium temperature is lower than the second temperature threshold, the heating component 46 is controlled to start and the temperature of the jet working fluid is increased, and when the medium temperature is higher than the third temperature threshold, the heating component 46 is controlled to shut down, and 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, the power component 44 is controlled to run at a low speed.

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

[0098] In a specific embodiment, if the electronic device is used in weather with relatively low temperatures, 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 rod is turned on. In this case, even if the electronic device is temporarily not operating, the power component 44 remains turned on to ensure that the liquid in the circulation pipeline can flow, to avoid freezing of the liquid in the circulation pipeline, so that the jet cooling system cannot work properly, and the frozen liquid may even damage the circulation pipeline; this method can also ensure that the temperature of the heating element 100 is not too low, to avoid the heating element 100 being unable to start up due to too low temperature, so that the electronic device can ensure its startup speed even at low temperatures, without the need for warm-up; it also avoids the problem of damage to the heating element 100 due to too low temperature. When the temperature detection component 47 detects that the water temperature at the outlet 115 of the jet working medium box 42 is greater than the third temperature threshold, for example, 10-12°C, the operation of the heating rod is stopped. If the temperature detection component 47 detects that the water temperature at the outlet 115 of the jet working medium box 42 is less than the second temperature threshold, the operation of the first fan 45 is stopped to prevent the water flow in the circulation pipeline from freezing due to the blowing of the first fan 45; if the temperature detection component 47 detects that the temperature exceeds the third temperature threshold during the period when the first fan 45 stops running, the first fan 45 is restarted.

[0099] In some embodiments, an air cooling component 7 is also included. The air cooling component 7 is arranged near the second heating element 102. The air cooling component 7 includes a second fan 71 and air cooling fins 72. The air cooling fins 72 are used to be installed on the shell body 3 to be cooled and are located next to the jet cooling component 1; the second fan 71 is arranged near the air cooling fins 72 to provide airflow for the air cooling fins 72; the second fan 71 is installed on the base of the shell body 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 airflow generated by the second fan 71 smoothly enters the air cooling fins 72; specifically, the jet cooling component 1 can be arranged between two adjacent air cooling fins 72, and the width of the air cooling fins 72 can be consistent with the width of the shell body 3 to be cooled, thereby increasing the contact area between the air cooling fins 72 and the shell body 3 to be cooled, thereby improving the heat exchange efficiency between the air cooling fins 72 and the shell body 3 to be cooled. Since the width of the jet cooling component 1 is smaller than the width of the shell body 3 to be cooled, such as Figure 1As shown, a sinking structure is formed between the jet cooling component 1 and two adjacent air-cooled heat sinks 72; further, a water outlet pipe 114 extends from the outlet 115 of the jet cooling component 1 to one side of the air flow direction of the air-cooled heat sink 72, and then extends to the air supply shell 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 arranged in contact with the surface of the shell 3 to be cooled, which not only facilitates the installation of the water outlet pipe 114, but also reduces the obstruction of the water outlet pipe 114 to the air flow in the air-cooled heat sink fins 72, thereby ensuring the air-cooled heat dissipation effect; through the above arrangement, the heat dissipation system becomes a heat dissipation system that combines air cooling and jet impact and can be used outdoors. Specifically, the sinking height of the sinking structure is 3-4 mm, and the water outlet pipe 114 is arranged along the sinking structure and fixed by a buckle 33 to ensure that the water outlet pipe 114 is 15-25 mm away from the air-cooled heat sink fins 72, thereby reducing the obstruction of the water outlet pipe 114 to the air flow in the heat sink fins, thereby reducing its impact on the heat dissipation effect.

[0100] In some embodiments, please refer to Figure 7 , an air-cooling air guide cover 73 is installed on the air-cooling heat dissipation fin 72, and the second fan 71 is located on the side of the air-cooling heat dissipation fin 72 provided with the air-cooling air guide cover 73; specifically, the upper part of the chassis fin is provided with an air-cooling air guide cover 73, which is used to guide the air flow and enhance 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 at the same time according to the temperature of the jet working fluid, so as to realize the mutual coordination of air cooling and jet cooling.

[0101] The above-mentioned electronic device dissipates heat through a heat dissipation system that combines air cooling and jet impact cooling. The jet impact is used to cool the heating element 100 with higher power consumption, and the remaining low-power heating elements 100 dissipate heat through air cooling. In this way, not only the heat dissipation capacity of the electronic device is enhanced, but also the requirements for the jet working fluid are lower and the safety is higher than that of other jet impact cooling methods. Since the liquid working fluid does not contact the heating element 100 in the shell 3 to be cooled, it is conducive to the later disassembly and maintenance. At the same time, this heat dissipation system can be used for outdoor servers. Under high outdoor ambient temperature conditions, jet impact cooling can effectively improve the heat exchange performance of the server. Combined with the phase change material in the jet working fluid box 42, it can improve the problem of damage to the heating element 100 caused by overheating of the server due to abnormal conditions under abnormal conditions. In a low temperature environment, it can ensure the rapid low-temperature startup of the server to avoid damage to the heating element 100 due to excessively low outdoor temperature.

[0102] This heat dissipation system enhances the heat dissipation capacity of the electronic device through jet impact cooling, and combines air cooling with jet impact cooling, thereby avoiding the influence on the layout of electronic devices inside the electronic device, which is beneficial to the design and manufacture of the electronic device; the jet impact liquid does not contact the electronic devices inside the electronic device, the reliability of the electronic device is greatly improved, and the later disassembly and maintenance of the electronic device is convenient; this type of electronic device can be used in outdoor environments, and the heat dissipation of the electronic device can be enhanced at high ambient temperatures through the preset heat dissipation system logic; the normal operation of the jet system can be ensured by the heating device and the low-temperature circulation logic under low ambient temperatures, while ensuring that the heating element 100 will not be damaged by overcooling, so that the temperature of the heating element 100 is maintained at a normal storage or operating temperature.

[0103] In addition to the above-mentioned heat dissipation system, the present invention further provides an electronic device including the above-mentioned heat dissipation system. For the structures of other parts of the electronic device, please refer to the relevant technology and will not be described in detail herein.
