Description

Technical Field

[0001] This utility model relates to the field of control box technology, specifically a heat dissipation and explosion-proof temperature control box. Background Technology

[0002] In fields such as industrial automation control and power electronic equipment, temperature control boxes serve as core equipment carriers and need to operate stably in complex environments. Their heat dissipation performance and explosion-proof safety directly affect the equipment's lifespan and system reliability. Existing temperature control boxes typically use traditional air-cooling or liquid-cooling methods under high-temperature conditions. While open air-cooling structures can dissipate heat quickly, external dust and moisture can easily enter the box through the heat dissipation holes, leading to corrosion or short circuits of electrical components. Especially in flammable and explosive environments, direct airflow poses a risk of spark ignition and cannot meet the high sealing and explosion-proof requirements. While fully enclosed liquid-cooling structures solve the explosion-proof problem, they are prone to local heat accumulation due to poor internal airflow organization and low heat exchange efficiency. Furthermore, traditional liquid-cooling pipeline layouts are simple and difficult to form efficient thermal coupling with the heat source inside the box, resulting in a decrease in temperature control accuracy. With the increasing power density of intelligent equipment, higher requirements are placed on the heat dissipation efficiency and explosion-proof performance of temperature control boxes in sealed environments. In existing technologies, how to build an efficient heat exchange channel to achieve coordinated heat dissipation of air and coolant while ensuring strict sealing of the box to isolate explosive gases has become a technical problem that the industry urgently needs to solve. In addition, traditional heat dissipation structures have problems such as high airflow resistance and insufficient heat exchange area, and lack targeted cooling design for heat-generating components such as motors, resulting in a lag in the overall temperature control system response, making it difficult to adapt to high-precision and high-safety industrial application scenarios. Therefore, there is an urgent need for a temperature control box structure that can take into account both sealed explosion-proof and efficient heat dissipation, and improve heat dissipation efficiency while ensuring equipment operation safety by optimizing airflow guidance and heat exchange paths. Utility Model Content

[0003] The purpose of this utility model is to provide a heat dissipation and explosion-proof temperature control box to solve the problems mentioned in the background art, such as the difficulty of existing temperature control boxes in achieving efficient heat dissipation while ensuring high sealing and explosion-proof requirements, and the existence of low heat dissipation efficiency, poor temperature control accuracy, and insufficient cooling of key components.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation explosion-proof temperature control box, comprising a box body, a rotating box cover installed on the outer surface of the box body, and a warning light fixedly installed on the upper end of the box body, a mounting box fixedly provided on the rear surface of the box body, one end of the mounting box penetrating through the inner surface of the box body, and a protective net fixedly connected to the end of the mounting box facing the inside of the box body, a guide plate fixedly provided inside the mounting box, and a motor fixedly installed inside the mounting box, with a fan fixedly connected to one end of the output shaft of the motor; The installation box is equipped with a heat exchange mechanism inside, which improves heat exchange efficiency while ensuring the airtightness of the box through closed heat exchange. The heat exchange mechanism includes a partition plate, which is fixedly installed inside the mounting box. An inlet is fixedly connected to the upper outer surface of the mounting box, and an outlet is fixedly connected to the middle outer surface of the mounting box. A heat exchange tube is connected between the end of the inlet located inside the mounting box and the end of the outlet located inside the mounting box. An exhaust connector is fixedly connected to the lower end of the mounting box, and an air inlet connector is fixedly installed on the rear surface of the box. A guide pipe is connected between the end of the air inlet connector located outside the box and the end of the exhaust connector located outside the mounting box.

[0005] Preferably, the guide plate is a hollow frustum-shaped design, with the smaller diameter end of the guide plate facing the fan, and the larger diameter end of the guide plate fitting against the outer surface of the protective net.

[0006] Using the above technical solution, the hollow frustum-shaped structure of the baffle plate can guide the hot air entering the mounting box inside the box. The smaller diameter end facing the fan can effectively gather the airflow, reduce airflow resistance, and allow the air to flow orderly along the inner wall of the baffle plate to the fan, thereby improving the airflow efficiency in the mounting box and providing good airflow conditions for subsequent heat exchange with the heat exchange tube.

[0007] Preferably, the outer surface of the partition plate is uniformly provided with holes, and the partition plate is located between the motor and the fan, and the motor shaft and the partition plate are rotatably connected.

[0008] By adopting the above technical solution, the evenly distributed holes on the outer surface of the partition plate allow air to flow smoothly between the motor and the fan. Driven by the airflow generated by the fan rotation, the heat generated by the motor during operation can be carried away in time, avoiding local heat accumulation around the motor. At the same time, the partition plate is rotatably connected to the motor shaft, which can provide stable support for the motor rotation and ensure the stability of the motor operation.

[0009] Preferably, the heat exchange tube is spiral-shaped at one end inside the mounting box, and the heat exchange tube is located on the side of the partition plate facing the motor.

[0010] Using the above technical solution, the heat exchange tube is designed in a spiral shape at one end inside the mounting box, which can greatly increase the contact area between the heat exchange tube and the air inside the mounting box. This allows the coolant to absorb heat from the air more fully when flowing through the heat exchange tube, thus enhancing the heat exchange effect. Furthermore, the heat exchange tube is located on the side of the partition plate facing the motor, which can cool the air passing through the motor. Combined with the holes on the partition plate, the cooled air can participate more effectively in the air circulation inside the box.

[0011] Preferably, the upper end of the exhaust connector penetrates the inner surface of the mounting box facing the motor side of the partition plate.

[0012] By adopting the above technical solution, the upper end of the exhaust connector penetrates the inner surface of the mounting box facing the motor side of the partition plate, so that the air cooled by the heat exchange tube in the mounting box can return to the box through the exhaust connector, guide pipe and air inlet connector, forming a closed air circulation path. While ensuring the airtight performance of the box, the air can circulate between the box and the mounting box, further improving heat dissipation efficiency and explosion-proof safety.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the heat dissipation explosion-proof temperature control box: 1. By setting up a closed circulation system consisting of an installation box and a guide pipe, the air inside the box is physically isolated from the outside, preventing dust, moisture and explosive gases from entering the box. This eliminates the problem of short circuits and corrosion of electrical components caused by external environmental factors. At the same time, this design eliminates the safety hazard of sparks igniting explosive gases in open heat dissipation structures, significantly improving the explosion-proof safety of the temperature control box in flammable and explosive environments, and ensuring that the equipment can operate stably in complex and harsh environments. 2. Furthermore, the spiral heat exchange tubes and the holes on the partition plate significantly increase the contact area between the coolant and the hot air inside the box, enhancing the heat exchange effect. The hollow frustum structure of the baffle plate can effectively guide the airflow, reduce airflow resistance, and make the air flow in an orderly manner within the mounting box, accelerating heat transfer. In addition, targeted cooling designs are implemented for heat-generating components such as the motor. The partition plate is located between the motor and the fan, which not only provides rotational support for the motor shaft but also quickly removes the heat generated by the motor through the airflow, preventing local heat accumulation and thus significantly improving the overall heat dissipation efficiency, ensuring a uniform and stable temperature inside the box. 3. Compared with traditional temperature control boxes, by optimizing airflow guidance and heat exchange paths, coordinated heat dissipation of air and coolant is achieved, effectively solving the problems of low thermal coupling efficiency and poor temperature control accuracy of traditional liquid cooling structures. This meets the stringent temperature control requirements of high-precision and high-safety industrial application scenarios, extends equipment service life, and ensures reliable system operation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 This utility model provides a technical solution: a heat dissipation and explosion-proof temperature control box.

[0018] Example 1: This example discloses: a box 1, a rotating box cover 2 installed on the outer surface of the box 1, a warning light 3 fixedly installed on the upper end of the box 1, a mounting box 4 fixedly installed on the rear surface of the box 1, one end of the mounting box 4 penetrating the inner surface of the box 1, and a protective net 5 fixedly connected to the end of the mounting box 4 facing the inside of the box 1, a guide plate 6 fixedly installed inside the mounting box 4, and a motor 7 fixedly installed inside the mounting box 4, and a fan 8 fixedly connected to one end of the output shaft of the motor 7; The guide plate 6 is a hollow frustum-shaped design, with the smaller diameter end of the guide plate 6 facing the fan 8, and the larger diameter end of the guide plate 6 fitting against the outer surface of the protective net 5. The enclosure 1 and the cover 2 form a sealed space. Warning signals are transmitted through the warning light 3. The mounting box 4 on the rear surface of the enclosure 1 is connected to the interior of the enclosure 1 through the protective net 5. The guide plate 6 is in the shape of a hollow frustum, with the large diameter end attached to the protective net 5 and the small diameter end facing the fan 8. The motor 7 drives the fan 8 to rotate, forming the air circulation power inside the enclosure 1. Hot air inside the housing 1 enters the mounting box 4 through the protective net 5. The guide plate 6 optimizes the airflow path, reduces resistance, and allows the air to flow orderly to the fan 8. After the fan 8 accelerates the air, it pushes the hot air to flow inside the housing 1 through the connection structure between the mounting box 4 and the housing 1, thus achieving air circulation. The protective net 5 prevents the fan 8 inside the mounting box 4 from being directly connected to the housing 1, ensuring that the inside of the housing 1 is relatively isolated from the mounting box 4, improving safety, and preventing the rotating fan 8 from being directly exposed.

[0019] Example 2: This example discloses, based on Example 1, that the installation box 4 is equipped with a heat exchange mechanism inside, which improves the heat exchange efficiency while ensuring the airtightness of the box 1 through a closed heat exchange method. The heat exchange mechanism includes a partition plate 9, which is fixedly installed inside the mounting box 4. An inlet 10 is fixedly connected to the upper outer surface of the mounting box 4, and an outlet 11 is fixedly connected to the middle outer surface of the mounting box 4. A heat exchange tube 12 is connected between the end of the inlet 10 located inside the mounting box 4 and the end of the outlet 11 located inside the mounting box 4. An exhaust connector 13 is fixedly connected to the lower end of the mounting box 4, and an air inlet connector 14 is fixedly installed on the rear surface of the box 1. A guide pipe 15 is connected between the end of the air inlet connector 14 located outside the box 1 and the end of the exhaust connector 13 located outside the mounting box 4. The outer surface of the partition plate 9 is evenly provided with holes, and the partition plate 9 is located between the motor 7 and the fan 8, and the rotating shaft of the motor 7 is rotatably connected to the partition plate 9; The heat exchange tube 12 is located inside the mounting box 4 with a spiral design at one end, and the heat exchange tube 12 is located on the side of the partition plate 9 facing the motor 7. The upper end of the exhaust connector 13 penetrates the inner surface of the mounting box 4 on the side of the partition plate 9 facing the motor 7; After the fan 8 draws out the air that has undergone preliminary heat dissipation from the mounting box 4, this air enters the guide pipe 15 through the exhaust connector 13, and then is transported to the air inlet connector 14 through the guide pipe 15, and finally returns to the box 1, forming a closed air circulation path. This design avoids the air inside the box 1 from directly contacting the outside, further improving the explosion-proof safety and preventing explosive gases from the outside from entering the box 1 and causing danger. A heat exchange mechanism is set inside the mounting box 4. Coolant flows in from the inlet 10 and enters the heat exchange tube 12 connected to the outlet 11. The spiral design greatly increases the contact area between the heat exchange tube 12 and the surrounding air, so that the coolant can absorb the heat of the air inside the mounting box 4 more fully. After absorbing the heat, the coolant flows out from the outlet 11, completing the heat dissipation cycle. The partition plate 9 provides stable rotational support for the shaft of the motor 7. At the same time, the holes on the partition plate 9 allow air to circulate between the motor 7 and the fan 8. During the air circulation process, the air flowing through the motor 7 can carry away the heat around the motor 7 in time, avoiding local heat accumulation in the motor 7 and achieving targeted cooling of key heat-generating components. Meanwhile, the cold air cooled by the heat exchange pipe 12 is quickly introduced into the housing 1 by the fan 8 and mixes with the hot air inside the housing 1, further reducing the temperature inside the housing 1. This achieves synergistic heat dissipation of air and coolant, significantly improving the overall heat dissipation efficiency.
