Description

Technical Field

[0001] This utility model relates to the field of heat conduction technology. More specifically, this utility model relates to a phase change medium filling platform for a heat storage product with a guide head. Background Technology

[0002] The seeker head, mounted on the nose of a guided weapon, is a device that measures the target's motion parameters relative to the weapon and generates guidance information. During use, it experiences a rapid increase in heat over a short period, necessitating rapid heat dissipation. Traditional cooling methods such as water cooling and air cooling are unsuitable for seeker heads; therefore, energy storage cooling is commonly used. This energy storage box is often filled with a phase change medium, such as paraffin wax. The phase change medium absorbs heat as it changes from a solid to a liquid state, thus lowering the temperature. Since the phase change medium is solid at room temperature, it needs to be melted into a liquid state for filling. A vacuum process is required before filling, but vacuuming devices cannot completely eliminate all air bubbles. Excessive air bubbles in the energy storage box can cause bulging or even rupture, severely impacting its lifespan. Utility Model Content

[0008] As a further embodiment of this utility model, a heater assembly two is provided on the base for heating the bottom of the energy storage box.

[0009] As a further embodiment of this utility model, the base is provided with baffles around its perimeter to form a trough, and insulation boards of different thicknesses are placed around the trough.

[0020] The present invention will now be described in detail and completely with reference to the accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention with reference to the accompanying drawings, it should be particularly noted that the technical solutions and features provided in the various parts of the present invention, including the following description, can be combined with each other without conflict.

[0021] Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the protection scope of the present invention.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific implementation process is as follows:

[0023] like Figure 1 As shown, this utility model provides a phase change medium filling platform for a guide head thermal storage product, including: a vacuum device 15, a phase change medium filling tank assembly and a base 11;

[0024] The base 11 is used to place the energy storage box 14 to be filled, and the energy storage box 14 is connected to the feed pipe 7 above it;

[0025] The phase change medium filling tank assembly includes a tank body 1, a heater assembly 2, and a stirring assembly. The tank body 1 has a feed inlet at the top and a discharge outlet at the bottom. The discharge outlet is connected to a discharge pipe 6, and the feed inlet is sealed by a cover. The heater assembly 2 is located inside the tank body 1 and is used to heat the phase change medium. The stirring assembly includes a motor 4 and a stirring rod 5. The stirring rod 5 is located inside the tank body 1 and is driven to rotate by the motor 4.

[0026] The vacuum device 15 is connected to the feed pipe 7 and the discharge pipe 6 through the first pipe 8 and the tee pipe. The discharge pipe 6 is equipped with a first switch valve 9 and the first pipe 8 is equipped with a second switch valve 10.

[0027] In this embodiment, during the phase change medium heating process, taking paraffin as an example, after it melts, the stirring component is turned on to make the paraffin heat more uniform. In addition, by stirring, the gas trapped in the paraffin liquid is more easily separated from the paraffin, reducing the bubble content in the paraffin liquid.

[0028] This technical solution may also include the following technical details to better achieve the technical effect: a heater assembly 3 is provided on the base 11 to heat the bottom of the energy storage box 14. The temperature of the paraffin wax accumulated at the bottom of the energy storage box 14 is lower than that of the paraffin wax at the top. Therefore, the heater assembly 3 is provided at the bottom to ensure the fluidity of the paraffin wax at the bottom of the tank 1.

[0029] This technical solution may also include the following technical details to better achieve the technical effect: the base 11 is provided with baffles 12 around its perimeter to form a groove one, and insulation boards 13 of different thicknesses are detachably placed around the groove one. The insulation boards 13 around the perimeter form a groove two for placing the energy storage box 14. The energy storage box 14 is provided with an insulation layer around its perimeter to prevent heat dissipation. The modular insulation structure can be adjusted according to the width of the energy storage box 14. In addition, by removing the insulation boards 13 to leave a gap, it is also convenient to take out the energy storage box 14 filled with phase change medium.

[0030] This technical solution may also include the following technical details to better achieve the technical effect: it also includes a frame for fixing the phase change medium filling tank assembly and the vacuum device 15, and the frame may also be connected to the base 11 as a whole.

[0031] This technical solution may also include the following technical details to better achieve the technical effect: an infrared thermometer is installed on the discharge pipe 6 to measure the temperature of the discharge pipe 6 body. The state of the paraffin in the tank 1 is determined by the temperature of the discharge pipe 6 body, thereby controlling the heating time of the paraffin in the tank 1.

[0032] This technical solution may also include the following technical details to better achieve the technical effect: the bottom of the tank 1 is a conical structure to facilitate the discharge of phase change media such as liquid paraffin.

[0033] How to use the phase change medium filling station for the guide head thermal storage product: Heat the paraffin wax in the tank 1 through heater assembly 2, and simultaneously turn on heater assembly 3 to heat the base 11. When the paraffin wax melts into liquid, then switch valve 9 is closed and switch valve 10 is opened. Start the vacuum device 15 to evacuate the pipeline and energy storage box 14. Then, switch valve 10 is closed and switch valve 9 is opened. Turn on the stirring assembly to fill the energy storage box 14 for a certain period of time. At this time, because the stirring assembly is turned on, the gas in the paraffin wax is more easily separated from the paraffin wax. After filling for a certain period of time, close switch valve 1 again and turn on switch valve 10 to evacuate the energy storage box 14 and pipeline again to reduce the amount of gas in the energy storage box 14. The paraffin wax in the energy storage box 14 is heated by heater assembly 3 to maintain the fluidity of the internal paraffin wax.

[0034] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
