Technical Field

[0001] This application relates to the field of heat exchange equipment, and more particularly to a phase change energy storage temperature control device used in data centers that utilizes dual homogeneous turbulent flow for heat exchange. Background Technology

[0002] In modern technology, temperature control is an indispensable part of many applications. Whether in industrial production, scientific research, or daily life, temperature control is crucial. Traditional temperature control methods mainly rely on electric heating and heat exchange systems, which control temperature by adjusting the power of heating elements or changing the flow rate of fluids. However, these methods also have some limitations, such as large temperature fluctuations and slow response times.

[0003] Existing temperature control devices mainly include electric heaters, heat exchangers, and temperature control systems. Electric heaters convert electrical energy into heat energy to heat the fluid flowing through them. Heat exchangers achieve temperature control by transferring heat from high-temperature fluids to low-temperature fluids. Temperature control systems maintain the set temperature by controlling the power of the heating element or the fluid flow rate. Current technical problems: Although existing temperature control technologies are widely used in various fields, some problems still exist. Due to the limitations of the heating efficiency of electric heaters and the heat transfer efficiency of heat exchangers, traditional temperature control devices often cannot accurately control the temperature, and temperature fluctuations are large, thus affecting testing efficiency and the accuracy of test data.

Detailed Implementation

[0030] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0031] This application provides a phase change energy storage temperature control device capable of outputting a liquid heat exchanger with a stable temperature. For example... Figure 1 , 2 As shown, it specifically includes a temperature control chamber 100, a liquid separation static pressure chamber 200 and a liquid outlet chamber 300. The liquid heat exchanger can flow sequentially through the liquid separation static pressure chamber 200, the temperature control chamber 100 and the liquid outlet chamber 300 to complete the heat exchange cycle.

[0032] Among them, such as Figure 1 As shown, the temperature control chamber 100 is rectangular, with one end face being a first end face 130, on which multiple secondary liquid equalization design holes 131 are provided. The opposite end face of the first end face 130 is a second end face 140, on which a first opening 141 is provided. A top sealing plate 110 is provided at the upper end of the temperature control chamber 100. The top sealing plate 110 is parallel to the bottom end face of the temperature control chamber 100. Multiple mounting holes 111 are provided on the top sealing plate 110 and arranged in an array. Multiple packed heat exchange tubes 120 are provided in the temperature control chamber 100 and are respectively disposed in the multiple mounting holes 111. The multiple packed heat exchange tubes 120 are fixed to the top sealing plate 110 by a fixing mechanism 112. A top cover plate 150 is provided at the top of the temperature control chamber 100 for sealing the temperature control chamber 100.

[0033] In this embodiment, the fixing mechanism 112 is a packing heat exchanger tube mounting seal. Multiple packing heat exchanger tube mounting seals are respectively provided corresponding to multiple mounting holes 111 and fixed to the top sealing plate 110. The multiple packing heat exchanger tube mounting seals, together with the packing heat exchanger tube 120, form a detachable and replaceable structure via chucks, flanges, or clamps.

[0034] In this embodiment, as Figure 6 As shown, multiple baffles 170 are fixedly installed inside the temperature control box 100. The multiple baffles 170 can disturb the liquid heat exchanger, causing it to enter a turbulent state, thereby improving the heat exchange efficiency of the liquid heat exchanger.

[0035] In this embodiment, as Figure 7 As shown, multiple secondary liquid equalization design holes 131 are arranged with equal diameters on the first end face 130, with the diameter of the secondary liquid equalization design holes 131 becoming smaller closer to the bottom of the first end face 130. Specifically, the diameters of the multiple secondary liquid equalization design holes 131 differ by 2 mm from top to bottom, and they are arranged with equal hole spacing of 40 mm or 50 mm, which can be specifically calculated using Bernoulli's equation. In addition, other hole diameter differences and other hole spacings can be used in other embodiments.

[0036] In this embodiment, the outer diameter of the packed heat exchange tube 120 differs from the inner diameter of the sealing component of the packed heat exchange tube by 2 mm. The packed heat exchange tube 120 is made of copper or stainless steel and is either an internally or externally threaded tube or a smooth tube.

[0037] In this embodiment, the top of the packed heat exchange tube 120 is open and sealed by a packed heat exchange tube mounting seal. The packing material in the packed heat exchange tube 120 is an organic phase change material and an inorganic phase change material. The organic phase change material includes paraffin wax, alkanes, and fatty acids; the inorganic phase change material includes hydrated crystalline salts and molten salts. The volume of the packing material is 80% to 90% of the internal volume of the packed heat exchange tube 120.

[0038] Among them, such as Figure 1 As shown, the liquid-liquid static pressure chamber 200 is sealed and fixedly mounted on the outer end face of the temperature control chamber 100, and covers the first end face 130. A second opening 230 is provided on the end face of the liquid-liquid static pressure chamber 200 that is in contact with the first end face 130. The liquid-liquid static pressure chamber communicates with the temperature control chamber 100 through multiple secondary liquid equalization design holes 131 that engage with the second opening 230. A liquid inlet 211 is provided on the liquid-liquid static pressure chamber 200 for the inflow of liquid heat exchanger. Figure 4 As shown, the upper surface of the separating static pressure chamber 200 has multiple primary equalization design holes 220. A tubular separator 210 is installed above the separating static pressure chamber 200. The tubular separator 210 includes multiple branch outlets 213, which cooperate with the multiple primary equalization design holes 220. The tubular separator 210 is connected to the inlet 211. A tubular separator guard plate 240 is installed outside the tubular separator 210 and is fixed to the upper surface of the separating static pressure chamber 200. The inlet 211 extends from the tubular separator guard plate 240. Multiple baffles 170 are also fixedly installed inside the separating static pressure chamber 200.

[0039] In this embodiment, as Figure 4 As shown, the tubular distributor 210 consists of a manifold 212 and multiple branch outlets 213. The branch outlets 213 have equal diameters, which ensures that the liquid heat exchanger can enter the hydrostatic chamber 200 evenly.

[0040] Among them, such as Figure 8 As shown, the liquid outlet chamber 300 is sealed and fixedly mounted on the outer end face of the temperature control chamber 100, and covers the second end face 140. A third opening 320 is provided on the end face of the liquid outlet chamber 300 that is in contact with the second end face 140. The liquid outlet chamber 300 communicates with the temperature control chamber 100 through the third opening and the first opening 141. A liquid outlet 310 is provided on the liquid outlet chamber 300 for the liquid heat exchanger to flow out.

[0041] Among them, such as Figure 1 , 2As shown, two caster mounting brackets 160 are fixedly installed on the lower end face of the temperature control box 100, and at least two casters 161 are spaced apart on each caster mounting bracket 160. The casters 161 allow operators to easily move the phase change energy storage temperature control device according to this application embodiment.

[0042] In this embodiment, water is used as the liquid heat exchanger. However, in other embodiments, other types of liquid heat exchangers, such as ethylene glycol, may also be used.

[0043] In this embodiment, the temperature control chamber 100, the liquid separation and static pressure chamber 200, and the liquid outlet chamber 300 are made of stainless steel plate. In other embodiments, other materials can also be used, such as painted cold-rolled steel plate, painted hot-dip galvanized steel plate, aluminum plate, or painted aluminum plate. The thickness of the sheet metal ranges from 0.8 to 2.0 mm. Furthermore, in other embodiments, sheet metal of other thicknesses can also be used to meet different application requirements.

[0044] The phase change energy storage temperature control device involved in the embodiments of this application mainly adopts dual flow equalization liquid separation technology and turbulent heat exchange technology.

[0045] The implementation steps of the dual flow equalization and liquid separation technology are as follows:

[0046] Step 1: The liquid heat exchanger enters the manifold 212 of the tubular distributor 210 through the inlet 211, and then flows evenly into the static pressure chamber 200 through multiple branch outlets 213 from multiple primary liquid equalization design holes 220, thus completing the first liquid separation.

[0047] In step two, the liquid heat exchanger flows through the second opening 230 to the secondary liquid equalization design hole 131, and then flows evenly into the temperature control chamber 100 from the secondary liquid equalization design hole 131, thus completing the second liquid distribution. The fluid heat exchanger is evenly distributed on the surface of each packed heat exchange tube 120, which can avoid temperature fluctuations caused by uneven distribution of the fluid heat exchanger.

[0048] The turbulent heat transfer technology uses baffles 170 to induce turbulence in the liquid heat transfer medium, creating turbulent disturbances between the packed energy storage heat exchange tubes 120. This turbulent heat transfer technology increases the contact area and contact time between the liquid heat transfer medium and the packed energy storage heat exchange tubes 120, improving heat transfer efficiency and thus enhancing the response speed of temperature control.

[0049] In addition, the multiple packed heat exchange tubes 120 arranged in the array of mounting holes 111 can improve the phase change heat transfer effect and stabilize the temperature of the constant temperature water tank. The multiple packed heat exchange tubes 120 are made of copper, which has good thermal conductivity and can reduce heat loss.

[0050] In summary, the phase change energy storage temperature control device described in this application, through two equalization and turbulent heat exchange processes and an array of multiple packed heat exchange tubes 120, can achieve precise temperature control of the temperature control chamber 100, thereby improving the quality and efficiency of industrial production. Secondly, in the field of scientific research, the phase change energy storage temperature control device described in this application can be used in various experimental equipment requiring a stable temperature environment. For example, in biomedical research, temperature control has a significant impact on cell culture and experimental results. The stable water temperature provided by the phase change energy storage temperature control device described in this application can provide a stable temperature environment for experimental equipment, thereby improving the accuracy and repeatability of experimental results. Finally, in the field of daily life, the phase change energy storage temperature control device described in this application can be used in various furniture and appliances requiring temperature control, such as household water heaters and air conditioners. It can achieve precise temperature control, improve user comfort, reduce energy waste, and lower operating costs. In summary, the phase change energy storage temperature control device involved in the embodiments of this application has broad application prospects in the field of temperature control, huge market demand, and is expected to become the mainstream of future temperature control technology.
