Description

Technical Field

[0001] This utility model relates to the field of explosion-proof enclosures, specifically a liquid cooling structure for explosion-proof enclosures. Background Technology

[0002] In the field of electrical cooling for explosion-proof enclosures in mines, existing technologies mainly employ two methods: one is to install a radiator outside the enclosure to allow for natural cooling by transferring heat from the enclosure; the other is to use heat pipe equipment outside the enclosure for cooling. However, both methods have significant drawbacks.

[0003] Natural cooling relies on heat conduction and natural convection within the enclosure, resulting in a complex structure and large size. This not only occupies considerable space but also provides less than ideal cooling performance, failing to meet the demands of efficient heat dissipation. Furthermore, its complex structure increases manufacturing costs and maintenance complexity.

[0004] While heat pipe cooling technology performs well in some aspects, its high cost limits its widespread application.

[0005] As the power of electrical equipment continues to increase, there is a need for a cooling solution that ensures both cooling effectiveness and cost reduction, in order to guarantee the normal operation and safety of the equipment. Utility Model Content

[0006] The purpose of this invention is to address the above problems by providing a liquid cooling structure for explosion-proof enclosures, which can reduce equipment costs while ensuring cooling effect.

[0007] To achieve the above objectives, the present invention adopts a liquid cooling structure for an explosion-proof enclosure, which includes a liquid cooling plate installed on the side wall of the explosion-proof enclosure. The liquid cooling plate has a liquid channel, and both ends of the liquid channel are connected to connectors. A radiator is installed on the liquid cooling plate and is located inside the explosion-proof enclosure. The radiator is connected to a structural component, which is open at both ends. A first fan is installed at one end of the structural component, and the airflow generated by the first fan blows out from the other end of the structural component.

[0008] Furthermore, to reduce processing difficulty, the liquid cooling plate includes a cooling plate and a cover plate, with the liquid channel located on the outer side of the cooling plate, and the cover plate sealing the outer side of the cooling plate. Thus, when processing the liquid channel, it is only necessary to use a milling machine to mill a groove on the outer surface of the cooling plate, and then use welding or other processes to connect the cover plate to the outer surface of the cooling plate to create the liquid channel.

[0009] Furthermore, the radiator is aligned with the structural component, and a second fan is located at one end of the radiator. The first and second fans are located at opposite ends of the structural component's length, and the airflow they generate is in opposite directions. During operation, the first and second fans generate airflows in opposite directions, creating a closed-loop airflow path. The first fan draws in cool air and blows it towards the electrical equipment within the structural component to remove its heat; the second fan directs hot air towards the radiator, which, through its connection with a liquid cooling plate, dissipates the heat, allowing the hot air to be cooled within the radiator, thus forming a continuous and effective air circulation. This design ensures that heat is efficiently transferred and dissipated, keeping the electrical equipment operating within a suitable temperature range.

[0010] The beneficial effects of this invention are as follows: By adopting a liquid channel and closed-loop air heat exchange design, this solution not only has a simple structure but also provides significant cooling effect, low cost, and is easy to design and manufacture for explosion-proof enclosures. It effectively solves the problems existing in current cooling technologies, providing a more stable and safer operating environment for electrical equipment. Attached Figure Description

[0013] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0014] Example 1, as Figure 1As shown, the structure of this embodiment is: a liquid cooling structure for an explosion-proof enclosure, which includes a liquid cooling plate 2 installed on the side wall of the explosion-proof enclosure 1. To install the liquid cooling plate 2 and improve the cooling effect, a through hole is opened on the side wall of the explosion-proof enclosure 1. The liquid cooling plate 2 is welded to the through hole by welding or other processes. A liquid channel 3 is provided inside the liquid cooling plate 2. Both ends of the liquid channel 3 are connected to connectors. The connectors are located on the liquid cooling plate 2 and are connected to an inlet pipe and an outlet pipe, respectively. To increase the heat exchange area, the liquid channel 3 is S-shaped. In order to reduce the processing difficulty, the liquid cooling plate 2 includes a cooling plate 201 and a cover plate 202. A groove is opened on the outer side of the cooling plate 201. The groove is S-shaped. The cooling plate 201 is fixed to the through hole on the side wall of the explosion-proof enclosure 1. After the S-shaped groove is milled on the outer side of the cooling plate 201 (facing the outside of the explosion-proof enclosure), the liquid channel 3 is sealed by welding the cover plate 202 to the outer side of the cooling plate 201.

[0015] A radiator 4 is installed on the cooling plate 201. The radiator 4 is located inside the explosion-proof enclosure 1. The radiator 4 is an aluminum profile radiator, a finned radiator, etc. The radiator 4 is connected to a structural component 5. The structural component 5 is a tubular structure with open ends. A first fan 6 is installed at one end of the structural component 5, and the airflow generated by the first fan 6 blows out from the other end of the structural component 5. The radiator 4 and the structural component 5 are arranged in the same direction. A second fan 7 is provided at one end of the radiator 4. The first fan 6 and the second fan 7 are located at opposite ends of the length of the structural component 5, and the airflow directions generated by them are opposite. Figure 1 (The middle arrow indicates the airflow direction). The heat sink 4 and structural component 5 are both located inside the protective cover 8, and components such as the power module are installed inside the structural component 5.

[0016] Cooling Principle: When the components within structural component 5 are operating, the first fan 6 on the left side of structural component 5 drives air from left to right through the components. The airflow carrying heat exits from the right end of structural component 5 and is then guided into the heat sink 4 by the second fan 7 on the same side. As the hot air flows through the heat sink 4 and completes heat exchange, the heat absorbed by the heat sink 4 is transferred to the cooling plate 201. Coolant enters the liquid channel 3 through the inlet pipe and exits through the outlet pipe, thus carrying away the heat from the heat sink. The cooled airflow exits from the left end of the heat sink 4 and is drawn back in by the first fan 6, blowing it again onto the components within structural component 5. This process creates a closed-loop air circulation within the protective cover 8, ensuring that the electrical components always operate within a suitable temperature range.
