Description

Technical Field

[0001] The utility model relates to the technical field of HVAC systems, in particular to a cold storage type air cooling device and an air cooling system. Background Art

[0002] In the event of a chilled water system failure or power outage, the chilled water system will not work. Some areas, such as battery-powered data centers and nuclear power plant control rooms, still need to maintain ambient temperature. In this case, these areas cannot be cooled, which ultimately leads to equipment failure and damage. Currently, the usual approach is to increase the redundancy of the chilled water system and add an emergency power supply system.

[0003] For example, two or more chilled water units are installed, one as a backup. When one chilled water unit fails, the other one is put into operation to ensure the reliability of the chilled water system. At the same time, a dedicated emergency diesel engine power supply is configured to provide emergency power supply for the chilled water unit when the power supply system is unavailable.

[0004] Although the above solution solves the problem of refrigeration demand in areas where the ambient temperature needs to be maintained, it increases the investment cost of the equipment and requires a large-capacity emergency diesel engine, resulting in high equipment procurement, operation and maintenance costs.

[0039] Referring to Figures 1 to 4, an embodiment of the utility model provides a cold storage type air cooling device, which includes a box body 100 and a heat exchange component 200. The box body 100 is configured with a cold storage space for storing a cooling medium; the heat exchange component 200 is at least partially arranged in the cold storage space, and the heat exchange component 200 is configured with a heat exchange channel 231 and an air inlet and an air outlet connected to the heat exchange channel 231; wherein the air inlet is connected to the air inlet pipe, and the air outlet is connected to the air outlet pipe, and the cooling medium can exchange heat with the heat exchange component 200 to cool the air in the heat exchange channel 231.

[0040] The technical solution provides a cold storage air cooling device, which is provided with a box 100, and a cold storage space capable of storing cooling medium is constructed on the box 100, and the heat exchange component 200 is at least partially arranged in the cold storage space, so that the heat exchange component 200 can exchange heat with the cooling medium in the cold storage space. By arranging a heat exchange channel 231 and an air inlet and an air outlet on the heat exchange component 200, the air can enter the heat exchange channel 231 from the air inlet, and after the heat exchange between the cooling medium and the heat exchange component 200, the air entering the heat exchange channel 231 is cooled, and then flows out from the air outlet to cool the environment that needs to be refrigerated. When the chilled water system fails or the normal power supply is lost, it can be used as an emergency cooling device to provide a cold source for the ventilation system and the temperature of the important area. The above technical solution adopts a non-active technology, which can provide a cold source for the ventilation system without relying on power supply, thereby saving the investment cost and operation and maintenance cost of the equipment.

[0041] It is understandable that the specific structure of the box 100 is not limited, and the box 100 can be a rectangular parallelepiped, a cylindrical structure, etc. The box 100 can be a plastic box 100, or can be made of stainless steel. In this embodiment, the box 100 is made of stainless steel. In this embodiment, the cooling medium can be one of frozen water, freezing liquid, or ice cubes.

[0042] As shown in Figures 1 and 2, in one embodiment, the heat exchange component 200 is arranged at the bottom of the box 100, so that after the cooling medium exchanges heat with the heat exchange component 200, the cooling medium at a relatively low temperature in the upper part of the box 100 flows downward into the area at the bottom of the box 100 where the heat exchange component 200 is arranged under the action of gravity, thereby realizing heat circulation.

[0043] As shown in FIG. 1 and FIG. 2, in one embodiment, a water inlet 110 is constructed on the box body 100, and the water inlet 110 passes through the box wall of the box body 100 to communicate with the cold storage space, and the water inlet 110 is connected to the cold source, so that the cooling medium in the cold source can flow into the cold storage space. Further, a water outlet 120 is also constructed on the box body 100, and the water outlet 120 passes through the box wall of the box body 100 to communicate with the cold storage space, and the water outlet 120 is connected to the liquid inlet of the cold source; wherein the water inlet 110 is connected to the liquid outlet of the cold source, so that a circulation loop is formed between the cold storage space and the cold source, and the cooling medium in the cold storage space can circulate between the cold storage space and the cold source.

[0044] As shown in FIG. 1 and FIG. 2 , by arranging a water inlet 110 and a water outlet 120 on the box body 100, and by connecting the water inlet 110 and the water outlet 120 with the liquid outlet and the liquid inlet in the cold source respectively, a circulation loop is formed, so that the cooling medium in the cold storage space can circulate. In this way, when the chilled water system can operate normally, the temperature of the cooling medium in the cold storage space is always in the best state, so as to prepare for emergency use.

[0045] Specifically, as shown in Figure 4, the cold source is a chilled water unit. When the chilled water unit is in power-on mode, the cooling medium can circulate between the cold storage space and the chilled water unit; when the chilled water unit is in power-off mode, the cooling medium in the cold storage space is disconnected from the chilled water unit.

[0046] When the chilled water unit is in the power-on mode, the cooling medium, that is, the cooling water, can circulate between the cold storage space and the chilled water unit to prepare for the subsequent emergency use of the cold storage air cooling device. When the chilled water unit is in the power-off mode, the cold storage air cooling device starts to work to exchange heat with the air in the heat exchange component 200 through the cooling medium stored in the cold storage space, thereby cooling the air in the heat exchange channel 231.

[0047] As shown in FIGS. 1 to 3 , in one embodiment, two mounting holes 130 are arranged opposite to each other on the box 100, and both ends of the heat exchange assembly 200 are arranged in the mounting holes 130 and sealed and fixed to the box 100. The mounting holes 130 are arranged on the box 100 to facilitate the installation of the heat exchange assembly 200 and the box 100. The heat exchange assembly 200 and the box 100 are sealed and fixed to prevent leakage at the connection between the heat exchange assembly 200 and the box 100, thereby ensuring the practical reliability of the cold storage type air cooling device.

[0048] As shown in Figure 1, in one embodiment, the heat exchange component 200 includes a first mounting plate 210, a second mounting plate 220 and a plurality of heat exchange pipes 230, the first mounting plate 210 is provided with an air inlet 211, and the first mounting plate 210 is used to be arranged in a mounting hole 130 of the box body 100; the second mounting plate 220 is provided with an air outlet 221, and the second mounting plate 220 is used to be arranged in another mounting hole 130 of the box body 100; a plurality of heat exchange pipes 230 are arranged in the cold storage space, and both ends of each heat exchange pipe 230 are respectively connected to the first mounting plate 210 and the second mounting plate 220, and both ends of each heat pipe are respectively connected to the air inlet 211 and the air outlet 221.

[0049] The integration of the heat exchange assembly 200 is improved by integrating multiple heat exchange pipes 230 on the first mounting plate 210 and the second mounting plate 220. The surface area of ​​the heat exchange assembly 200 is increased by providing multiple heat exchange pipes 230, thereby improving the heat exchange effect and further improving the cooling effect on the area requiring refrigeration.

[0050] Furthermore, the first mounting plate 210 and the second mounting plate 220 are welded and fixed to the box body 100. This arrangement makes the structure of the entire cold storage type air cooling device simpler while ensuring the sealing performance of the connection between the box body 100 and the heat exchange assembly 200, thereby further reducing the cost.

[0051] In one embodiment, the heat exchange pipe 230 may be a threaded pipe. Setting the heat exchange pipe 230 as a threaded pipe can increase the surface area of ​​the heat exchange pipe 230, thereby further improving the heat exchange effect. Of course, the heat exchange component 200 can also be set as a fin-type structure or a guide plate-type structure. These structures have the effect of increasing the heat exchange area, thereby improving the heat exchange performance.

[0052] The utility model also provides an air cooling system, which includes the above-mentioned cold storage air cooling device. By using the above-mentioned cold storage air cooling device in the air cooling system, when the chilled water system fails or the normal power supply is lost, it can be used as an emergency cooling device to provide a cold source for the ventilation system and the temperature of important areas. The above-mentioned technical solution adopts non-passive technology, which can provide a cold source for the ventilation system without relying on power supply, thereby saving the investment cost and operation and maintenance cost of the equipment.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
