Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology, and in particular relates to a heat dissipation and cooling device for electrical cabinets. Background Technology

[0002] As a component of large electromechanical equipment, the main function of the chassis is to house various electronic and electrical components, providing support and protection. In addition, the chassis also shields electromagnetic radiation. Chassis is generally made of sheet metal. However, the operation of various electronic and electrical components generates a lot of heat. The enclosed space inside the chassis makes it difficult for the heat to dissipate, causing the surface temperature of various electronic and electrical components to rise, which will affect the reliability or other performance of the components.

[0003] In the prior art, patent document with publication number "CN214409800U" discloses a circulating cooling heat dissipation chassis, including a chassis body, a circulating water cooling device installed on the chassis body, an internal cooling fan installed inside the chassis body, and an external cooling fan installed outside the chassis body. The chassis body is provided with a first serpentine cooling pipe and a second serpentine cooling pipe, which are respectively located on both sides of the internal cooling fan. The circulating water cooling device includes a circulating water tank with a built-in water pump, a first radiator connected to the circulating water tank and the first serpentine cooling pipe, and a second radiator connected to the circulating water tank and the second serpentine cooling pipe. The external cooling fan is located above the circulating water tank, and its air outlet is directly facing the first and second radiators. Using this patented technical solution, the cooling water is driven by the water pump to circulate, so that the cooling water dynamically removes electronic components and electrical components from the chassis during the circulation process, thereby achieving the purpose of heat dissipation and cooling of electronic components and electrical components.

[0004] However, when the electromechanical equipment loses power and stops, the corresponding heat dissipation and cooling devices and water pumps will also lose power and stop. A lot of heat will remain inside the chassis. Because the water pump loses power and stops, the heat remaining inside the chassis cannot be dissipated in time, which will also affect the reliability and service life of electronic and electrical components. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a heat dissipation and cooling device for electrical cabinets.

[0006] This utility model provides a heat dissipation and cooling device for an electrical cabinet, including a cabinet shell and an external cold source. The cabinet shell is equipped with a cold storage box and a heat exchange tube. One end of the heat exchange tube is connected to the external cold source through a liquid inlet pipe, and the other end of the heat exchange tube is connected to the external cold source through a cold exhaust pipe. The cold storage box is equipped with a cold storage tank, which is connected in series between the external cold source and the heat exchange tube, or the two ends of the cold storage tank are connected in parallel with the two ends of the heat exchange tube respectively.

[0007] The cold storage tank is a non-closed-loop elongated shape that has been bent and twisted multiple times inside the cold storage box. The cold storage tank consists of multiple transverse guide channels and multiple longitudinal guide channels. The transverse guide channels and the longitudinal guide channels are arranged alternately and are interconnected.

[0008] The cold storage box is also equipped with multiple heat-conducting fins, which are connected between two adjacent transverse guide grooves and between two adjacent longitudinal guide grooves.

[0009] The surface of the cold storage box is also provided with a filling hole, which is connected to the transverse guide groove or the longitudinal guide groove.

[0010] The cross-section of the cold storage tank is rectangular.

[0011] The heat exchange tube is a non-closed-loop strip shape that has been bent and twisted multiple times inside the casing.

[0012] The casing is also equipped with a support frame, and the heat exchange tube is fixedly connected to the support frame.

[0013] The shell is a cuboid shape assembled from multiple thin metal plates.

[0014] The support frame is a cuboid shape assembled from multiple aluminum profiles.

[0015] The beneficial effects of this utility model are as follows: By using the technical solution provided by this utility model, an additional cold storage tank is set inside the chassis. When the heat dissipation and cooling device is running, the cold storage tank can store an appropriate amount of coolant. At the same time, the coolant also flows along the heat exchange tubes, dynamically removing the heat energy generated by various electronic and electrical components from the outside of the chassis. When the electromechanical equipment is powered off and shut down, the residual heat energy inside the chassis can still be absorbed by the coolant stored in the cold storage tank, thereby allowing the surface of the electronic and electrical components to continue to cool down, effectively protecting the electronic or electrical components, and allowing the residual heat energy inside the chassis to dissipate in time, improving the reliability of the electronic or electrical components and extending their service life.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the description. This utility model provides a heat dissipation and cooling device for electrical cabinets, such as... Figures 1 to 5 As shown, it includes a housing 1 and an external cold source 2. The housing 1 is equipped with a cold storage box 3 and a heat exchange tube 4. One end of the heat exchange tube 4 is connected to the external cold source 2 through a liquid inlet pipe 5, and the other end of the heat exchange tube 4 is connected to the external cold source 2 through a cold exhaust pipe 6. The cold storage box 3 is equipped with a cold storage tank 7, which is connected in series between the external cold source 2 and the heat exchange tube 4, or the two ends of the cold storage tank 7 are connected in parallel to the two ends of the heat exchange tube 4 respectively.

[0019] By adopting the technical solution provided by this utility model, an additional cold storage tank is set inside the chassis. When the heat dissipation and cooling device is running, the cold storage tank can store an appropriate amount of coolant. At the same time, the coolant also flows along the heat exchange tubes, dynamically removing the heat energy generated by various electronic and electrical components from the outside of the chassis. When the electromechanical equipment is powered off and shut down, the residual heat energy inside the chassis can still be absorbed by the coolant stored in the cold storage tank, thereby allowing the surface of the electronic and electrical components to continue to cool down, effectively protecting the electronic or electrical components, and allowing the residual heat energy inside the chassis to dissipate in time, improving the reliability of the electronic or electrical components and extending their service life.

[0020] Specifically, the cold storage tank 7 is a non-closed-loop elongated shape that has been bent and twisted multiple times inside the cold storage box 3. The cold storage tank 7 is composed of multiple transverse guide channels 8 and multiple longitudinal guide channels 9. The multiple transverse guide channels 8 and multiple longitudinal guide channels 9 are arranged alternately, and the transverse guide channels 8 and longitudinal guide channels 9 are interconnected.

[0021] In addition, the cold storage box 3 is equipped with multiple heat-conducting fins 10, which are connected between two adjacent transverse guide grooves 8 and between two adjacent longitudinal guide grooves 9. Using the technical solution of this utility model, the heat-conducting fins 10 can be made of aluminum alloy. The heat generated by electronic or electrical components and remaining inside the box can be absorbed by the heat-conducting fins 10, further improving heat dissipation efficiency. This allows the electronic or electrical components to cool down to room temperature as quickly as possible after the electromechanical equipment is powered off, reducing wear and tear on the electronic or electrical components and extending their service life.

[0022] In addition, the surface of the cold storage tank 3 is also provided with a filling hole 11 and a discharge hole 13. The filling hole 11 is connected to the transverse guide groove 8 or the longitudinal guide groove 9, and the discharge hole 13 is connected to the transverse guide groove 8 or the longitudinal guide groove 9. The filling hole 11 is used to inject phase change material into the cold storage tank 7, while the discharge hole 13 is used to discharge the phase change material in the cold storage tank 7. Phase change material refers to a substance that changes its state of matter and can provide latent heat while the temperature remains constant. When the phase change material changes its physical process, it can absorb or release heat energy. Therefore, by utilizing the phase change characteristics of phase change material, when electronic components or electrical components are powered off, they can be cooled to room temperature as quickly as possible, reducing wear and tear on electronic components or electrical components and extending their service life.

[0023] Specifically, the cross-section of the cold storage tank 7 is rectangular. The heat exchange tube 4 is a non-closed-loop elongated shape that has undergone multiple bends and turns within the casing 1. A support frame 12 is also provided inside the casing 1, and the heat exchange tube 4 is fixedly connected to the support frame 12. The casing 1 is a cuboid shape assembled from multiple thin metal plates. The support frame 12 is a cuboid shape assembled from multiple aluminum profiles.
