Description

Technical Field

[0001] This utility model belongs to the technical field of cabinet heat dissipation equipment, and specifically relates to a cabinet cooling and temperature control device. Background Technology

[0002] The existing server rack uses phase change material modules with an air delivery system. The air delivery system delivers the cooling capacity of the air conditioner to the phase change modules and the inside of the server rack. The phase change modules undergo a phase change to maintain a constant temperature inside the server room for a fixed period of time. During peak electricity price periods, the air conditioner is turned off, and the cooling capacity is released by the phase change material. In the case of high temperatures both outside and inside the server rack, the temperature inside the server rack is controlled, reducing energy consumption. However, since there is only one air conditioner continuously outputting cooling capacity inside the server rack, the cooling capacity supply is insufficient, especially in the case of high outside temperatures. The temperature drop inside the server rack is small, and some equipment still experiences high temperatures.

[0003] Therefore, there is an urgent need for a cabinet cooling and temperature control device that is more efficient in heat dissipation and has a greater cooling range. Utility Model Content

The heat pipe plate is obliquely inserted into the cabinet through the mounting groove. The end of the heat pipe plate inside the cabinet is the cold end and the end of the heat pipe plate outside the cabinet is the hot end. The position of the cold end is higher than the position of the hot end.

[0025] Example 1:

[0026] In this embodiment, a cabinet cooling and temperature control device, such as... Figure 1 and Figure 2 As shown, the device includes a housing 1, an air conditioner 2, a phase change module system, and a heat pipe plate 3. Specifically, the air conditioner 2 and the phase change module system are installed inside the housing 1. The phase change module system can exchange heat with cold air to store some of the cold energy. The housing 1 is provided with a cold air outlet 4, a natural air inlet 5, and a mounting slot. The heat pipe plate 3 is obliquely inserted into the housing 1 through the mounting slot. The heat pipe plate 3 is a structural component made based on the heat pipe principle. It contains a working fluid, such as distilled water or deionized water, which can undergo a liquid-vapor phase change when exchanging heat with the outside. The end of the heat pipe plate 3 inside the housing 1 is the cold end 7, and the end of the heat pipe plate 3 outside the housing 1 is the hot end 8. The position of the cold end 7 is higher than the position of the hot end 8.

[0027] With this structure, the working fluid in the hot end 8 of the heat pipe plate 3 absorbs heat and vaporizes in the cabinet. It rises to the cold end 7 by the upward movement of the gas, thereby transferring heat to the cold end 7. It exchanges heat with the cold air generated by the air conditioner 2 in the cabinet 1, and then liquefies and releases heat in the cabinet 1. Then, under the action of gravity, it flows back to the hot end 8 to absorb heat and vaporize again. This achieves the effect of continuously transferring the heat of the cabinet to the cabinet 1 and the cold energy of the cabinet 1 to the cabinet. The heat dissipation is faster, the temperature drop is greater, and the cold energy supply is more abundant, making the utility model more practical.

[0028] As one specific implementation method of this embodiment, such as Figure 2 and Figure 3As shown, the aforementioned housing 1 is divided into an upper chamber 9 and a lower chamber 10 by a partition 11. The cold end 7 of the aforementioned air conditioner 2 and heat pipe plate 3 is located in the aforementioned upper chamber 9. The top of the aforementioned housing 1 is provided with an air inlet 6, that is, the top of the aforementioned upper chamber 9 is provided with an air inlet 6. The aforementioned air inlet 6 is connected to the air inlet end of the aforementioned air conditioner 2 through a pipe, thereby introducing external air and cooling it through the aforementioned air conditioner 2. The aforementioned phase change module system is located in the aforementioned lower chamber 10. The aforementioned partition 11 is provided with a grid hole 12 for connecting the aforementioned upper chamber 9 and lower chamber 10. The cold air generated by the aforementioned air conditioner 2 enters the aforementioned lower chamber 10 through the aforementioned grid hole 12, and then exchanges heat with the aforementioned phase change module system, so that some of the cooling capacity is stored in the aforementioned phase change module system for later use.

[0029] In this embodiment, as Figure 1 As shown, the cold air outlet 4 is connected to the lower chamber 10, and there are two natural air inlets 5, which are respectively connected to the upper chamber 9 and the lower chamber 10. The cold air outlet 4 is equipped with an exhaust fan 13, and the natural air inlets 5 are equipped with electric air valves 14. The fans provide continuous power for the air inside the housing 1 to flow from the upper chamber 9 to the lower chamber 10, thereby blowing cold air into the cabinet, accelerating the transfer efficiency of cooling, and improving the operating efficiency of the device. When the outside temperature is higher than... When the internal temperature of the cabinet reaches a certain level, the air conditioner 2 starts up. The generated cold air first exchanges heat with the cold end 7 of the heat pipe plate 3 in the upper chamber 9, causing the hot working fluid gas in the cold end 7 to cool and liquefy. Then, it enters the lower chamber 10 to exchange heat with the phase change module system for cold storage. Finally, it is delivered to the cabinet through the cold air outlet 4 to cool the heat-generating equipment. When the temperature inside the cabinet reaches the preset temperature, the air conditioner 2 goes into standby mode. At this time, the phase change module system releases the stored cold energy, which is then delivered to the cabinet through the cold air outlet 4. This extends the standby time of the air conditioner 2, avoids frequent start-stop cycles, and reduces energy consumption. When the outside temperature is lower than the internal temperature of the cabinet, the air conditioner 2 is in standby mode. At this time, the electric air valve 14 is opened, and the electric air valve 14 delivers external natural cold air to the upper chamber 9 and the lower chamber 10. The natural cold air exchanges heat with the cold end 7 of the heat pipe plate 3 in the upper chamber 9 and with the phase change module system in the lower chamber 10 for heat storage. Finally, it is delivered to the heat-generating equipment inside the cabinet through the cold air outlet 4. Cooling can further reduce the energy consumption of the air conditioner 2. When the temperature inside the cabinet is too high, the electric air valve 14 can also operate in reverse to quickly exhaust the overheated air inside the cabinet. In addition, when the electricity price is at its peak, the air conditioner 2 can be turned off. At this time, when off-peak electricity or normal electricity is released, the cooling capacity stored in the phase change module system allows the released cold air to exchange heat with the cold end 7 and be released into the cabinet through the cold air outlet 4 to cool the inside of the cabinet, thereby reducing the energy consumption of the air conditioner 2 during peak electricity price periods.

[0030] In this embodiment, the right side wall of the box 1 is provided with a single door 15, and the two natural air inlets 5 are opened on the single door 15. The single door 15 facilitates the maintenance and replacement of the electric air valve 14 and the phase change module system.

[0031] In this embodiment, as Figure 2 and Figure 3 As shown, the phase change module system includes multiple phase change energy storage tubes 16. The partition 11 is provided with multiple arrayed insertion holes 19. The bottom wall of the lower chamber 10 is provided with multiple arrayed slots. Each insertion hole 19 and each slot is connected to a phase change energy storage tube 16, so that the multiple phase change energy storage tubes 16 are arranged in an array and vertically spaced within the lower chamber 10, thereby exchanging heat with the passing cold air from the air conditioner 2 or natural cold air. The phase change energy storage tubes 16 are filled with solid-liquid phase change cold storage material. The solid-liquid phase change cold storage material can exchange heat with the outside through solid-liquid phase change to achieve the function of cold storage and cold release. It is preferably a straight-chain alkane or an inorganic salt. The cold air generated by the air conditioner 2 blows through the multiple phase change energy storage tubes 16 and exchanges heat with them, so that the solid-liquid phase change cold storage material stores cold.

[0032] As an optimization, the aforementioned phase change energy storage tube 16 is a tapered tube, preferably an aluminum tapered container with a taper coefficient of 0.125, which increases the heat exchange area of ​​the solid-liquid phase change cold storage material, thereby improving the heat exchange efficiency, shortening the cold storage and release time of the solid-liquid phase change cold storage material, and further reducing the energy consumption of the air conditioner 2.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, it also includes a convection fan 17 and a connecting arm 18. One end of the connecting arm 18 is connected to the convection fan 17 and the other end is connected to the housing 1. The convection fan 17 is suspended above the hot end 8 of the heat pipe plate 3. The convection fan 17 is used to concentrate the hot air inside the cabinet and blow it to the hot end 8 of the heat pipe plate 3, thereby accelerating the vaporization process of the working fluid in the heat pipe plate 3 and improving the heat transfer efficiency of the heat pipe plate 3. The connecting arm 18 is a steel wire rope that can be bent at will to adjust the direction of the convection fan 17, so that the convection fan 17 can absorb hot air from multiple directions.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
