[0002] In recent years, there are strict requirements for the integration, light weight, and miniaturization of electronic devices. The high degree of integration has led to a sharp increase in the thermal power density of electronic devices, while the miniaturization and light weight have caused a decrease in the heat capacity of the devices. The thermal control problem of electronic devices has become increasingly prominent. The heat dissipation performance of electronic chips directly affects the reliability and working performance of electronic devices. The high-efficiency temperature control technology has become one of the key technologies restricting the development of electronic devices.

[0003] In a radar seeker, the transceiver (TR) power amplifier chip has a small volume, a large power density, and low efficiency. Once the chip temperature reaches the critical value of the allowable temperature, it will seriously endanger the stability and reliability of its operation, and may even cause burnout.

[0004] With the continuous improvement of the requirements for radar performance improvement, relying solely on the methods of metal heat transfer or phase change material heat storage has the defects of poor thermal conductivity, low heat dissipation efficiency, and insufficient heat storage capacity in a limited space. The existing heat dissipation methods are not sufficient to control the chip temperature within a reliable range. At the same time, the method of using an active liquid cooling system for cooling has the disadvantages of complex structure, high energy consumption, and high cost, and it cannot be well matched and applied in the seeker. Therefore, there is an urgent need to provide a new radiator to improve the heat transfer performance of the TR cold plate and ensure the normal and stable operation of the chip.

The gas pipeline is used to export the gas generated in the evaporator; one end of the liquid pipeline is connected to the lower part of the condenser, and the other end is connected to the evaporator; the condenser can condense the gaseous working medium into a liquid state, and the liquid pipeline can export the liquid working medium condensed in the condenser to the evaporator.

[0049] In this embodiment, the heating device to be cooled is a radar; the TR module of the radar is fixedly connected to the evaporator 1 of the two-phase temperature-controlled radiator by means of screw connection. Specifically, the cover plate 101 of the evaporator 1 is in direct contact with the electronic devices of the tile-type TR module of the radar, and the electronic devices are cooled by relying on the characteristics that the liquid working medium inside the evaporator 1 evaporates and boils to absorb a large amount of heat.

[0050] Further, a thermal interface material is coated on the contact surface between the TR module and the cover plate 101 of the evaporator 1 to reduce the contact thermal resistance. Specifically, the thermal interface material can be selected from thermal conductive silicone grease, thermal conductive gel, thermal conductive pad, etc.

[0051] Further, a liquid filling pipe is processed on one side of the evaporator 1, and the liquid filling pipe is located on the side of the evaporator 1 and is used to pour the liquid working medium into the evaporator 1.

[0052] Specifically, the material of the evaporator 1 includes but is not limited to metal materials such as stainless steel, aluminum alloy, magnesium alloy, and copper.

[0054] As Figure 2 shown, the two sides of the evaporator 1 are respectively connected with a gas pipeline 2 and a liquid pipeline 4, and are connected to the condenser 3 through the gas pipeline 2 and the liquid pipeline 4.

[0055] Specifically, welding is used for sealing at the pipeline joints to ensure that there is no gas or liquid leakage in the temperature control radiator.

[0056] In a specific embodiment of the present invention, the capillary evaporation core 102 can not only enhance the heat exchange of the working medium, but also be processed inside the inner cavity of the evaporator 1 by sintering or etching.

[0057] The structural form of the capillary evaporation core 102 can be a fiber material with capillary liquid absorption effect; or, sintered from metal powder; or, formed by machining grooves on the workpiece surface.

[0058] Specifically, the capillary evaporation core 102 is made of a material with capillary liquid absorption function.

[0059] Alternatively, the capillary evaporation core 102 is sintered with metal powder on the surfaces of the cover plate 101 and the substrate 103 and is located inside the evaporator 1.

[0060] Alternatively, the capillary evaporation core 102 is formed by grooves. The specific method is as follows:

[0061] As Figure 5 shown, the capillary evaporation core 102 is in the shape of a comb and includes: a semi-circular water storage plate 1021 and a comb tooth structure 1023.

[0062] Among them, a water storage cavity is provided inside the semi-circular water storage plate 1021 for storing the liquid working medium; the comb tooth structure 1023 is linear, and a plurality of comb tooth structures 1023 are arranged side by side on the side of the semi-circular water storage plate 1021; a drainage inner flow channel 1024 is provided inside the comb tooth structure 1023, and the drainage inner flow channel 1024 is communicated with the water storage cavity.

[0063] Specifically, a water inlet 1022 is provided on the side of the semi-circular water storage plate 1021. The water inlet 1022 is used to connect the liquid pipeline 4; the liquid working medium condensed by the condenser 3 can flow back to the capillary evaporation core 102 through the water inlet 1022.

[0064] Specifically, a plurality of capillary liquid outlet holes 1025 are provided on the side of the comb tooth structure 1023. The capillary liquid outlet holes 1025 penetrate through the outer surface of the drainage inner flow channel 1024 and the comb tooth structure 1023; the liquid inside the capillary evaporation core 102 can be led out to the outer surface of the comb tooth structure 1023 through the drainage inner flow channel 1024 and the capillary liquid outlet holes 1025; and then it can evaporate and absorb heat.

[0065] In a specific embodiment of the present invention, as Figure 4 shown, the condenser 3 is a curved pipeline.

[0066] Furthermore, the curved pipeline includes: an S-shaped pipeline and a U-shaped pipeline.

[0067] Further, the S-shaped pipelines and U-shaped pipelines are arranged alternately, and multiple groups of S-shaped pipelines and U-shaped pipelines are connected in sequence.

[0068] Further, the S-shaped pipeline is composed of a straight pipe section and two arc pipe sections connected to both ends of the straight pipe section.

[0069] Further, the U-shaped pipeline is composed of an arc pipe section and two straight pipe sections connected to both ends of the arc pipe section.

[0070] Further, the arc pipe section is a semi-circular arc pipe.

[0071] In a specific embodiment of the present invention, according to the requirement of the heat dissipation power, one group or multiple groups of condensers 3 are provided; the structural schematic diagram of the double condensers is as Figure 4 shown. Specifically, the materials of the condenser 3 include but are not limited to metal materials such as stainless steel, aluminum alloy, magnesium alloy, and copper.

[0072] The condenser 3 of the present invention is mainly in the form of a pipeline, which can be integrally formed with the aircraft skin, and the cabin wall is used as a heat exchange heat sink to exchange heat with the external air.

[0075] During implementation, the heat generated by the TR component is conducted to the evaporator 1 of the two-phase temperature-controlled radiator through the thermal interface material, and then the heat is transferred to the internal liquid working medium through the capillary evaporation core 102 inside the evaporator 1. The liquid working medium is heated and evaporated, boils after reaching the saturation temperature, and absorbs a large amount of heat. The vaporized working medium flows through the gas pipeline 2 to the condenser 3, and then the condenser 3 condenses the vaporized working medium into a liquid working medium by exchanging heat with the heat sink (external environment). Finally, the liquid working medium flows back to the evaporator 1 through the liquid pipeline 4 to complete the thermal dissipation cycle. During the cycle, the heat generated by the TR component is exported to the condenser and then exported to the natural environment through the condenser.

[0076] Embodiment 2

[0077] In a specific embodiment of the present invention, on the basis of Embodiment 1, an alternative solution for the evaporator 1 in Embodiment 1 is provided:

[0078] In this embodiment, asFigure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown in Figure 10 , the evaporator 1 has a multi-layer structure and includes an evaporation layer plate 111, a transition layer plate 112, a water storage layer plate 113, and a capillary wick 117.

[0079] Specifically, an evaporation cavity is provided inside the evaporation layer plate 111, a plurality of through holes are provided inside the transition layer plate 112, and a water storage cavity is provided inside the water storage layer plate 113.

[0080] Specifically, the capillary wick 117 is cylindrical and is arranged in the through holes of the transition layer plate 112.

[0081] Specifically, as shown in Figure 6 , Figure 8 , and Figure 10 , the upper end of the capillary wick 117 extends out of the upper surface of the transition layer plate 112 and is located in the evaporation cavity. The lower end of the capillary wick 117 extends out of the lower surface of the transition layer plate 112 and is located in the water storage cavity. The capillary wick 117 can absorb the liquid working medium in the water storage cavity and then introduce the working medium into the evaporation cavity.

[0082] Further, as shown in Figure 7 , a plurality of fixing cylinders 116 are arranged in an array in the evaporation layer plate 111; the upper end of the capillary wick 117 is nested in the fixing cylinder 116, so as to fix the capillary wick 117 and accelerate the evaporation and heat absorption of the working medium inside it.

[0083] Further, an air outlet pipe 114 and a water return pipe 115 are provided on the side of the evaporator 1.

[0084] Among them, the air outlet pipe 114 is communicated with the air inlet of the gas pipeline 2 and is used to export the gas working medium generated in the evaporator 1. The water return pipe 115 is communicated with the water outlet of the liquid pipeline 4 and is used to introduce the liquid working medium flowing back from the condenser 3 into the evaporator 1. Specifically, the air outlet pipe 114 is communicated with the evaporation cavity inside the evaporation layer plate 111, and the water return pipe 115 is communicated with the water storage cavity inside the water storage layer plate 113.

[0085] The capillary wick 117 can be made of a fiber material with a liquid absorption effect or a capillary layer is formed on the surface of a metal pipe by sintering metal powder; the lower end of the capillary wick 117 does not contact the lower surface of the water storage cavity; and the fixing cylinder 116 does not contact the upper surface of the transition layer plate 112. When the capillary wick 117 is a metal pipe with a capillary layer, air holes are opened on its surface.

[0086] ​​​​​​​​During implementation, the evaporation layer plate 111 is used to contact and connect with the heating device, and thus can absorb the heat generated by the TR component to increase the temperature; the heated evaporation layer plate 111 transfers the heat to the capillary wick 117 and the liquid working medium in the evaporator 1 through the fixing cylinder 116; after the liquid working medium absorbs heat, it vaporizes, and then enters the condenser 3 through the gas pipeline 2. When the gaseous working medium flows out of the evaporator 1, it takes away the heat in the evaporator 1. The gaseous working medium exchanges heat with the condenser 3, and then transfers the heat to the external environment through the condenser 3; the gaseous working medium releases heat and condenses to the liquid state in the condenser 3, and then the liquid working medium flows back to the water storage cavity of the evaporator through the liquid pipeline 4. The capillary wick 117 can introduce the liquid working medium from the water storage cavity into the evaporation cavity. The heat generated by the TR component can vaporize the liquid working medium and thus promote its circulation between the condenser 3 and the evaporator 1, realizing the circulating heat dissipation of the working medium.

[0087] In this embodiment, by arranging the capillary wick 117 that penetrates the evaporation cavity, the transition layer plate 112 and the water storage cavity, the continuous supply of the liquid working medium for evaporation is realized; furthermore, by arranging a plurality of fixing cylinders 116, the heat exchange between the evaporation layer plate 111 and the capillary wick 117 is promoted. The liquid working medium stored in the capillary wick 117 is directly heated and evaporated by the fixing cylinder 116, accelerating the conversion and transmission of thermal energy, and finally improving the heat dissipation efficiency of the TR component.

[0088] Embodiment 3

[0089] A specific embodiment of the present invention is an improvement based on Embodiment 1 or 2, and provides an alternative solution for the condenser in Embodiment 1:

[0090] In this embodiment, as Figure 11 、 Figure 12 、 Figure 13 shown, the condenser 3 includes: an air inlet plate 301, a liquid storage plate 302, and a condensate pipe 303.

[0091] As Figure 11 、 Figure 12 shown, an air storage cavity 306 is provided inside the air inlet plate 301, and a water collecting cavity 307 is provided inside the liquid storage plate 302; the condensate pipe 303 is connected between the air inlet plate 301 and the liquid storage plate 302, and both ends of the condensate pipe 303 are respectively communicated with the air storage cavity 306 and the water collecting cavity 307.

[0092] Furthermore, as Figure 12 、 Figure 13 shown, in order to promote the heat exchange between the condensate pipe 303 and the high-temperature steam and promote the effect of steam condensation and liquefaction, a condensate component 308 is provided inside the condensate pipe 303. Specifically, the condensate component 308 is arranged inside the condensate pipe 303 and is fixedly connected to the condensate pipe 303.

[0093] Furthermore, the condensate component 308 is composed of multiple condensate units connected in series in sequence.

[0094] As Figure 14 , Figure 15 shown, the condensate unit includes: a water inlet pipe 3081 and an umbrella-shaped structure; wherein, one end of the water inlet pipe 3081 is provided with a set of umbrella-shaped structures, or two sets of umbrella-shaped structures are symmetrically arranged at both ends of the water inlet pipe 3081.

[0095] Specifically, the umbrella-shaped structure includes: an annular structure 3082 and arc-shaped ribs 3083; a plurality of the arc-shaped ribs 3083 are provided, and the plurality of arc-shaped ribs 3083 are installed on the inner side of the annular structure 3082 in a circumferential array manner, and the arc-shaped ribs 3083 are fixedly connected to the water inlet pipe 3081.

[0096] Specifically, the arc-shaped ribs 3083 are inclined, with their upper ends fixedly connected to the annular structure 3082 and their lower ends fixedly connected to the water inlet pipe 3081.

[0097] As Figure 16 shown, when two sets of umbrella-shaped structures are symmetrically arranged on both sides of the water inlet pipe 3081, the annular structures 3082 of multiple condensate units are in contact and connected with each other, and are fixed by welding or bonding.

[0098] As Figure 17 shown, when the umbrella-shaped structure is arranged on only one side of the water inlet pipe 3081, multiple condensate units are connected in series in sequence and fixedly connected.

[0099] In this embodiment, the liquid working medium in the evaporator 1 generates high-temperature steam after heat exchange with the TR component. The high-temperature steam enters the air chamber 306 of the condenser 3 through the gas pipeline 2, and then is diverted to multiple condensate pipes 303 through the air chamber 306; after the steam enters the condensate pipe 303, it exchanges heat with the pipe body of the condensate pipe 303 and the condensate unit inside it. The water droplets formed after heat exchange and condensation will adhere to the surface of the condensate unit. When the condensed liquid increases, it will flow into the inside of the water inlet pipe 3081 along the arc-shaped ribs 3083 or flow along the outer wall of the water inlet pipe 3081, and finally converge and flow into the water collecting chamber 307 at the bottom of the condenser 3, and then flow back to the evaporator 1 through the liquid pipeline 4 for re-heat exchange.

[0100] The condenser 3 of the present invention can achieve rapid cooling and heat exchange of high-temperature steam, and can achieve the convergence and drainage of the liquid after condensation, promoting the effective progress of the radiator cycle heat exchange.
