Description
Technical Field
[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a control box for a fire pump system. Background Technology
[0002] Currently, fire-fighting equipment is increasingly widely used in chemical enterprises, playing a crucial role, especially in ensuring the safe evacuation of personnel and the safety of critical facilities during fires. As the scale of production in the chemical industry continues to expand and production processes are constantly upgraded, the requirements for fire safety are also becoming increasingly stringent. Therefore, improving the reliability of fire-fighting equipment, particularly its performance in extreme environments, has become one of the urgent problems to be solved.
[0003] Most fire pump control boxes currently on the market rely on traditional heat dissipation devices to maintain system stability. These traditional heat dissipation devices typically include fans and heat sinks. Among them, fan cooling solutions remove heat by forced airflow, but are less efficient in high-temperature environments; heat sinks rely on natural cooling to regulate temperature, but due to the lack of an active heat dissipation mechanism, they are difficult to effectively protect electronic components from damage under prolonged high-temperature conditions.
[0004] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: most existing fire pump control boxes rely on passive ventilation for heat dissipation, which has significantly lower heat dissipation efficiency under high-intensity continuous operation. Moreover, ventilation and heat dissipation can easily allow external dust to enter the control box, resulting in a lot of dust inside the control box affecting the safety of electronic components. Therefore, a control box for fire pump systems is now proposed. Utility Model Content
[0005] In order to improve the problem that most existing fire pump control boxes rely on passive ventilation for heat dissipation and have poor heat dissipation and dust prevention effects, this utility model provides a control box for fire pump systems.
[0006] This utility model provides a control box for a fire pump system, which adopts the following technical solution:
[0007] A control box for a fire pump system includes a control box body, a heat conduction component, and a heat dissipation component. The heat conduction component includes a heat conduction cylinder, a circulating fan, and a spiral heat conduction pipe. There are two heat conduction cylinders, which are respectively fixedly installed on both sides of the control box body. There are two sets of circulating fans, which are respectively installed on both sides of the control box body. Each set of circulating fans has two fans, which are respectively located at both ends of the heat conduction cylinder. The spiral heat conduction pipe is installed inside the heat conduction cylinder.
[0008] The heat dissipation assembly includes a heat dissipation box, a water tank, a water pump, an inlet water pipe, a return water pipe, and a cooling component. The heat dissipation box is fixedly installed at the bottom of the control box. The water tank is located inside the heat dissipation box. The water pump is connected to one side of the water tank. The inlet water pipe is connected between the water pump and one end of the spiral heat-conducting pipe. The return water pipe is connected between the other end of the spiral heat-conducting pipe and the water tank. The cooling component is installed on the back of the water tank.
[0009] By adopting the above technical solution, and by setting up heat conduction components, a circulating fan can be started to circulate the heat inside the control box into the heat conduction cylinder. By setting up heat dissipation components, a water pump can be started to circulate the water in the water tank through the water inlet pipe and the water return pipe into the spiral heat conduction pipe. When the cooling water flows along the spiral heat conduction pipe, it can absorb the heat in the heat conduction cylinder, thereby reducing the heat inside the control box. At the same time, there is no airflow exchange between the inside of the control box and the outside, thereby completely preventing dust from entering the control box, thus achieving both good heat dissipation and dust prevention effects.
[0010] Optionally, the spiral heat pipe is made of copper.
[0011] By adopting the above technical solution, the copper tube has the best thermal conductivity, which can ensure the heat transfer performance of the spiral heat pipe.

[0015] By adopting the above technical solution, a cooling chip is a device that uses the thermoelectric effect of semiconductor materials to achieve cooling. It consists of many neatly arranged PN junction semiconductor chips. Each chip has metal wires at both ends and is connected to an electrical connector. When current passes through the PN junction in the semiconductor chip, the PN junction absorbs heat and releases the cold end. The hot end is then cooled by a heat sink and a cooling fan, thereby generating cold air.
[0016] Optionally, the cooling fan extends to the outside of the heat sink, and a protective net is fixedly installed on the back of the heat sink near the cooling fan.
[0017] By adopting the above technical solution and setting up a protective net, the cooling fan can be protected.

[0020] Optionally, the control box is hinged to a door on the front, and the door is provided with an observation window.
[0021] By adopting the above technical solution, the control box can be sealed through the door, and the interior of the control box can be easily observed through the observation window.
[0022] Optionally, the control box is equipped with a main control unit, a power supply module, and a temperature control detection module.
[0023] By adopting the above technical solution, the main control unit is composed of a microprocessor as its core, which is responsible for receiving external signals and processing the start and stop commands of the fire pump. The power supply module is used to supply power to the main control unit and other electrical components. The temperature control and detection module monitors the internal temperature changes in real time based on the temperature sensor and feeds the data back to the main control unit. The main control unit drives the heat conduction component and the heat dissipation component to work.

At the same time, there is no airflow exchange between the inside of the control box and the outside, thereby completely preventing dust from entering the control box, thus achieving both good heat dissipation and dust prevention effects.

There can be multiple temperature sensors, which are distributed in different positions inside the control box body 1 to monitor the temperature at different locations inside the control box body 1 in real time.
[0034] Reference Figure 1 and Figure 2The heat conduction component 2 includes a heat conduction cylinder 21, a circulating fan 22, and a spiral heat conduction pipe 23. There are two heat conduction cylinders 21, which are fixedly installed on both sides of the control box 1. The heat conduction cylinders 21 are arranged vertically. There are two sets of circulating fans 22, which are installed on both sides of the control box 1. Each set of circulating fans 22 has two fans, which are located at both ends of the heat conduction cylinder 21. By setting the heat conduction component 2, the circulating fans 22 can be activated to circulate the heat in the control box 1 into the heat conduction cylinder 21. Several evenly distributed heat dissipation fins 24 are fixedly connected to the outer surface of the heat conduction cylinder 21.

The return water pipe 35 is connected to the spiral heat pipe 23. Between the other end of the heat pipe 23 and the water tank 32, a heat dissipation component 3 is installed. The water pump 33 can be started to circulate the water in the water tank 32 through the water inlet pipe 34 and the water return pipe 35 to the spiral heat pipe 23. When the cooling water flows along the spiral heat pipe 23, it can absorb the heat in the heat pipe 21, thereby reducing the heat in the control box 1.

It consists of many neatly arranged PN junction semiconductor chips, each with metal wires at both ends connected to an electrical connector. When current flows through the PN junction in the semiconductor chip, the PN junction absorbs heat and releases a cold end. The cold end of the cooling chip 361 cools the water in the water tank 32, and the hot end is cooled by the heat sink 362 and the cooling fan 362. A protective net 364 is fixedly installed on the back of the heat sink 31 near the cooling fan 363 to protect the cooling fan 363.

[0037] In addition, considering the different needs of different application scenarios, auxiliary heat dissipation measures can be added, such as adding more additional heat dissipation fins or configuring a more powerful motor to drive stronger airflow to help cool down quickly.
[0038] The implementation principle of this utility model is as follows: When the control box is working, the main control unit 13, composed of a microprocessor as its core, is responsible for receiving external signals and processing the start and stop commands of the fire pump. The power supply module 14 is used to supply power to the main control unit and other electrical components. The temperature control detection module 15 monitors the internal temperature changes in real time based on the temperature sensor and feeds the data back to the main control unit 13. The main control unit 13 drives the heat conduction component 2 and the heat dissipation component 3 to work. During heat dissipation, the circulating fan 22 can be started to circulate the heat in the control box 1 into the heat conduction cylinder 21. Then, the water pump 33 can be started to pump water from the water tank 32 through the water inlet pipe 34 and... The return water pipe 35 circulates the water to the spiral heat-conducting pipe 23.
