Description
Technical Field
[0001] This utility model relates to the field of heat dissipation technology for aerospace single-unit electronic components, and in particular to a heat-conducting and temperature-equalizing energy storage device. Background Technology
[0002] The trend towards integration, lightweighting, and miniaturization of electronic components has led to the problem of concentrated heat generation due to high heat flux density in electronic devices. If the generated heat cannot be dissipated in time, the temperature of electronic devices will rise rapidly, affecting their normal operation. Electronic components also exist within aerospace units, and their integration is even higher, making the concentrated heat generation phenomenon more pronounced. Therefore, energy storage devices are typically installed on the base plate of aerospace units as heat sinks. These devices are filled with an energy storage medium and have internal thermal conductivity enhancement structures. The latent heat of phase change of the energy storage medium and the thermal conductivity of the enhancement structures are used to dissipate heat from the electronic components. Typical thermal conductivity enhancement structures are metal particles or metal pillars. However, metal particles, due to their uneven distribution, result in random heat transfer, while metal pillars have poor thermal conductivity, leading to low heat transfer efficiency.
[0003] To address the aforementioned problems, existing technologies provide a isothermal phase change energy storage device, comprising a shell, an energy storage cavity within the shell, and multiple ribs arranged within the energy storage cavity. All ribs are fixedly connected to the shell and are parallel to each other in pairs, forming a flow channel between two parallel ribs. This flow channel is not interconnected with the energy storage cavity. The energy storage cavity is filled with a phase change energy storage medium, and a pulsating heat pipe is installed within the flow channel. The pulsating heat pipe contains a working medium, the thermal conductivity of which is greater than that of the phase change energy storage medium. The use of a pulsating heat pipe replaces the traditional thermal conductivity enhancement structure of metal cylinders or metal particles, providing a definite direction for heat transfer and improving heat transfer efficiency to some extent. However, the small contact area between the working medium and the phase change energy storage medium results in slow heat transfer speed, low heat transfer efficiency, and low energy storage efficiency for the energy storage device.

By installing a temperature equalization component within the energy storage cavity, the contact area between the temperature equalization component and the energy storage medium is increased, accelerating the heat transfer speed, improving the heat transfer efficiency, and ultimately enhancing the energy storage efficiency of the energy storage device.

The placement of the heat transfer element 33 makes the heat transfer efficiency between the bent pipe section 213 and the heat-conducting elements 31 faster. Specifically, in this embodiment, the heat transfer element 33 is disposed between the bent pipe section 213 and the heat-conducting elements 31. In other embodiments, the heat transfer element 33 may also be disposed between the straight pipe section 212 and the connecting element 32, etc. No limitation is made here.
[0074] Specifically, such as Figure 5 As shown, in this embodiment, the heat transfer element 33 is a silicone rubber-based high thermal conductivity interface material, specifically a thermally conductive silicone pad. While transferring heat, it also buffers the rigid impact between the bent section 213 and the heat transfer element 31. In other embodiments, the heat transfer element 33 can also be thermally conductive silicone or thermally conductive tape, etc. No limitations are imposed here.
[0075] Furthermore, the outer casing 1 has a second filling port 12, which communicates with the energy storage cavity 11. The thermally conductive and temperature-equalizing energy storage device also includes a second sealing element 6, which can seal the second filling port 12. The above configuration allows energy storage medium to be filled into the energy storage cavity 11 and can seal the energy storage cavity 11 to prevent leakage of the energy storage medium.
[0076] Specifically, in this embodiment, the second sealing element 6 is welded to seal the second filling port 12. Specifically, the second filling port 12 is sealed using argon arc welding. This results in high weld quality and a low tendency for deformation at the weld joint. In other embodiments, the second sealing element 6 can use any method of the prior art to seal the second filling port 12, as long as it can prevent leakage of the energy storage medium.
[0077] This embodiment also provides a spacecraft unit, including a spacecraft unit body and a thermally conductive and temperature-equalizing energy storage device. The spacecraft unit body includes an electronic component section, and the thermally conductive and temperature-equalizing energy storage device is disposed on the spacecraft unit body, with at least a portion of the thermally conductive and temperature-equalizing energy storage device covering the electronic component section. By incorporating the thermally conductive and temperature-equalizing energy storage device, the speed of heat transfer is accelerated, the efficiency of heat transfer is improved, and the energy storage efficiency of the energy storage device is increased.
[0078] Optionally, in this embodiment, the thermally conductive and temperature-equalizing energy storage device completely covers the electronic component section. This allows for faster heat dissipation from the electronic component section. In other embodiments, the thermally conductive and temperature-equalizing energy storage device may cover half of the electronic component section, etc., and there are no limitations here.
[0079] The following describes the temperature-storage principle of the thermally conductive temperature-storage energy storage device in this embodiment:
[0080] When the electronic components generate concentrated heat, the energy storage medium in the energy storage cavity 11, which is in contact with the concentrated heat source, begins to gradually absorb heat and melt. Meanwhile, the working medium in the temperature equalization component 2 located within the energy storage medium absorbs heat and evaporates to generate bubbles, causing the working medium to expand and pressurize rapidly. This propels the working medium towards the energy storage medium in the non-concentrated heat source area within the energy storage cavity 11. Since the temperature of the energy storage medium in the non-concentrated heat source area is low, the bubbles cool, release heat, contract, and burst, reducing the pressure. This transfers heat to the non-concentrated heat source area through the temperature equalization component 2. Because the temperature equalization component 2 is in direct contact with the energy storage medium, the contact area between the temperature equalization component 2 and the energy storage medium is increased, causing the energy storage medium in the non-concentrated heat source area to melt rapidly. This ensures that the energy storage medium in the energy storage cavity 11 melts evenly when heated, thereby rapidly transferring heat from the concentrated heat source area, improving the efficiency of heat transfer, and increasing the energy storage efficiency of the energy storage device.
