[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The core of this invention is to provide a temperature control device with a reasonable layout and a relatively compact structure.

[0026] For a specific embodiment of the refrigeration equipment provided by this invention, please refer to [the original text]. Figure 1 and Figure 2 It includes the chassis and the electrical control components 3, air-cooling components, water-cooling components and heat exchanger 6 built into the chassis.

[0027] Both the air-cooled and water-cooled components are connected to the heat exchanger 6 for heat exchange, so that the coolant in the water-cooled component is cooled by the air-cooled component. Specifically, the heat exchanger 6 is a plate heat exchanger, but it can also be a shell-and-tube or shell-and-tube heat exchanger, or it can be a tube-fin heat exchanger (e.g., copper tube with aluminum fins), or it can be a parallel flow heat exchanger.

[0028] The chassis includes a first mounting plate 15 and a second mounting plate 14. The electronic control assembly 3 and the water cooling assembly are located close to both ends of the first mounting plate 15, wherein the two ends of the first mounting plate 15 and the two ends of its extending direction correspond to... Figure 2 The first mounting plate 15 has a water inlet 152 and a water outlet 153 connected to the water cooling assembly. The first mounting plate 15 has an air inlet 151 and the second mounting plate 14 has an air outlet 141.

[0029] When cooling is required, the coolant of the external device to be regulated enters the water-cooled assembly through inlet 152. The air-cooled assembly exchanges heat with the coolant in the water-cooled assembly at heat exchanger 6 to achieve cooling. The cooled coolant in the water-cooled assembly flows out through outlet 153 and then enters the external device. Specifically, the external device used for temperature control is an energy storage device such as a battery pack. In other embodiments, it can also be applied to other devices such as variable temperature cabinets.

[0030] In this embodiment, the first mounting plate 15 can be used to conveniently position the electronic control component 3 and the water cooling component in the chassis. The remaining positions in the chassis can be used to assemble the air cooling component. The air vents on the first mounting plate 15 and the second mounting plate 14 can be used to form a smooth airflow channel for the air cooling component. At the same time, the wind-blocking electronic control component 3, water cooling component and other devices are located on both sides of the airflow channel, which can reduce the wind resistance in the chassis. The space in the chassis is clearly divided, the layout is reasonable, and the structure is compact.

[0031] Furthermore, the first mounting plate 15 is detachably fixed to the chassis, for example, by screw connection. Specifically, the chassis also includes a third mounting plate 18 and a fourth mounting plate 19 disposed opposite to the first mounting plate 15 and the second mounting plate 14, such that the first mounting plate 15, the second mounting plate 14, the third mounting plate 18, and the fourth mounting plate 19 form a quadrilateral frame, and the two ends of the first mounting plate 15 are detachably fixed to the third mounting plate 18 and the fourth mounting plate 19, respectively. The electronic control component 3 can be removed and installed in the chassis by pulling it out after the first mounting plate 15 is removed, which facilitates the installation and removal of the electronic control component 3 without having to remove the entire refrigeration equipment from its installation position.

[0032] Optionally, the first mounting plate may also be equipped with an electrical quick-connect connector 17 for convenient electrical connection of the electrical control component 3 to other devices. When maintenance of the electrical control component 3 is required, the incoming line of the temperature control device can be disconnected from the electrical quick-connect connector 17 first, and then the fasteners of the first mounting plate 15 can be removed to pull the electrical control component 3 out of the chassis for maintenance. Of course, in other embodiments, the first mounting plate 15 may also be non-removably fixed to the chassis.

[0033] Furthermore, the air-cooled assembly includes a fan assembly, a condenser 2, a compressor 4, a throttling device 5, and intermediate connecting pipes. The compressor 4, condenser 2, throttling device 5, and heat exchanger 6 are connected in sequence to form a closed-loop refrigerant flow path. When the air-cooled assembly and heat exchanger 6 are running, the compressor 4 compresses the refrigerant within it into a high-temperature, high-pressure gas that flows to the condenser 2. The condenser 2 is connected to the throttling device 5, and the condenser 2, through heat exchange with the fan assembly, transforms the high-temperature, high-pressure gas into a normal-temperature, high-pressure gas that flows to the throttling device 5. After being throttled by the throttling device 5, the gas flows to the heat exchanger 6, and after heat exchange in the heat exchanger 6, it returns to the compressor 4, forming a closed system.

[0034] Preferably, the fan assembly includes multiple fans 1 respectively disposed close to the second mounting plate 14, for example, three. In other embodiments, other numbers may be used, such as one or four. Additionally, the air outlet 141 can be configured one-to-one with the fans 1. Specifically, a fan plate parallel to the second mounting plate 14 is provided in the chassis to divide the area near the second mounting plate 14 within the chassis into a fan cavity for assembling the fans 1. Using multiple fans 1 results in a larger air volume, allows for lower fan speeds, and reduces operating noise.

[0035] Preferably, the center of the first mounting plate 15 is an air inlet 151, and an air inlet filter 16 covering the air inlet 151 is fixed to the first mounting plate 15 to filter the air entering the chassis. Specifically, the air inlet filter 16 is externally mounted on the chassis and is detachably connected to the first mounting plate 15. After the temperature control equipment is assembled with the external equipment, the first mounting plate 15 can be positioned as the front. When maintaining the components, the air inlet filter 16 or the first mounting plate 15 can be removed from the front of the temperature control equipment to maintain components such as the water-cooling components and the electronic control components 3.

[0036] Preferably, the condenser 2 has a V-shaped structure, with its concave side facing the air outlet 141. Using a V-shaped bent condenser 2 allows for maximum heat exchange area within a limited space, reducing the power of the compressor 4 or fan 1 while meeting requirements, effectively reducing overall noise. Of course, in other embodiments, the condenser 2 can also be a flat plate structure.

[0037] Preferably, the compressor 4, the electronic control component 3, and the water-cooling component are all located on the protruding side of the condenser 2, i.e. Figure 2 The compressor 4 is located on the lower side of the intermediate condenser 2. It is positioned close to the first mounting plate 15 and between the water-cooling assembly and the electronic control assembly 3, making full use of the space between them and further enhancing the compactness of the structure. Additionally, the fan assembly is located on the recessed side of the condenser 2.

[0038] Preferably, the electrical control component 3 is positioned close to the third mounting plate 18, and the heat exchanger 6 and water cooling component are positioned close to the fourth mounting plate 19, so that the two inclined portions of the V-shaped condenser 2 can fully utilize the two included angle spaces formed by the third mounting plate 18 and the fourth mounting plate 19 respectively.

[0039] Furthermore, the water-cooling assembly includes a water pump 9, a heater 10, and a connecting piping system. The inlet 152, water pump 9, heat exchanger 6, and outlet 153 are sequentially connected to form a coolant flow channel 10, which can connect to the flow channel of external equipment through the inlet 152 and outlet 153. Specifically, the heater 10 is a water-electric heater. With the addition of the heater 10, the heat exchanger 6 and the air-cooling assembly can be activated, or the heater 10 can be activated, thus the water-cooling assembly can perform both cooling and heating functions to adaptively regulate the temperature of the external equipment. Of course, in other embodiments, the heater 10 may not be included.

[0040] Preferably, the water-cooling assembly further includes a water filter 8 and an expansion tank 13. The water filter 8 is connected between the inlet 152 and the water pump 9, and the expansion tank 13 is connected to the water filter 8, serving as a constant-pressure water supply. The coolant from the external device enters the water filter 8 through the inlet 152 to filter out foreign matter, then enters the water pump 9. The water pump 9 provides power to drive the coolant into the heat exchanger 6 for heat exchange, and after passing through the heater 10, it flows back to the external device through the outlet 153.

[0041] Preferably, in the extending direction of the first mounting plate 15, i.e. Figure 2 In the left-right direction, the water pump 9, expansion tank 13, and heater 10 are along the direction away from the electronic control component 3 (i.e., Figure 2 The water filter 8 and expansion tank 13 are arranged sequentially from the center to the right, with the water filter 8 and expansion tank 13 arranged in a direction away from the first mounting plate 15 (i.e., from the center to the right). Figure 2 Arranged sequentially (from center to top), the expansion tank 13 is connected to a branch in the middle of the water filter 8, and the two ends of the water filter 8 are connected to the water pump 9 and the inlet 152, respectively. Figure 2 As shown, in the left-right direction, by adding a branch in the middle of the water filter 8 to connect to the expansion tank 13, and connecting the water pump 9 and the water inlet 151 to the left and right ends respectively, the space in the chassis can be effectively utilized.

[0042] Preferably, the inlet 152 is connected to a liquid injection ball valve 11, which allows for the replenishment of liquid to the water-cooled components. Simultaneously, during maintenance of the water pump 9 and water filter 8, the liquid in the water-cooled components can be released through the liquid injection ball valve 11. Specifically, the inlet 152 is equipped with an inlet quick-connect fitting 7, and the outlet 153 is equipped with an outlet quick-connect fitting 12. The use of quick-connect fittings facilitates the connection and installation of external equipment and subsequent maintenance. Optionally, the liquid injection ball valve 11 is connected below the inlet quick-connect fitting 7.

[0043] The temperature control device provided by this invention has the following advantages: it can be installed in an energy storage device as a small, plug-in type chiller. The installation position of the temperature control device on the energy storage device can be adjusted according to needs, specifically, it can be inserted into the battery pack position of the energy storage device; the overall layout of the internal components is such that the electronic control component 3 is on one side of the temperature control device, part of the air-cooled component is in the middle, and the water-cooled component is on the other side, with a clear overall distribution. The wind-blocking components are distributed on both sides of the temperature control device, which can greatly reduce the resistance of the overall frame, resulting in a compact structure and small footprint, making it suitable for small energy storage device applications; multiple fans 1 are used to achieve low speed and low noise; the first mounting plate 15 and the air inlet filter 16 are detachable, allowing maintenance of components such as the electronic control component 3 and the water pump 9 without disassembling the entire unit. The electronic control component 3 can be maintained by removing the first mounting plate 15 and pulling it out; the condenser 2 adopts a V-shaped structure, which can achieve the maximum heat exchange area in a limited space.
