What is electric cabinet dehumidifier construction

Do you know the electric cabinet dehumidifier construction? This article will introduce the internal and external structures of the electrical cabinet dehumidifier to you.

Internal electrical cabinet dehumidifier construction

The internal structure of dehumidifier includes Fan, cooling fin, power module, circuit borad, flume, and semiconductor condenser.

Fan of dehumidifier

Fan is a core component for electrical cabinet dehumidifier. It draws moist air into the machine, processes it, and then expels the dry air. During the dehumidification process, the fan can also assist in heat dissipation to prevent the cabinet dehumidifier from overheating. To reduce noise and increase durability, the fan blades are made of lightweight and high-strength materials such as aluminum alloy or ABS.

Cooling Fin

Cooling fin is an indispensable cabinet dehumidifier construction. It is usually made of metal material like cooper or aluminum, has a large surface area, and its main function is to accelerate the transfer of heat. During the operation of the cabinet dehumidifier, the refrigerant changes state from gas to liquid and then from liquid to gas. This process generates a lot of heat. The function of the Cooling Fin is to quickly transfer this heat to the surrounding air to achieve the purpose of cooling.

Flume

The enclosure dehumidifier flume collects water droplets condensed on the cooling fins and directs them to the drainage system.

Circuit Board

The circuit board is the core component of the cabinet dehumidifier. It controls the operation of the entire cabinet dehumidifier. From starting and stopping to humidity adjustment and fault alarm, all are inseparable from the precise control of the circuit board. The circuit board mainly contains a microcontroller (MCU), a temperature sensor, a temperature sensor, a relay, a transistor and other components. Its working principle is as follows: the humidity sensor detects the ambient humidity and transmits the signal to the MCU. The MCU determines whether dehumidification is required based on the humidity data and the set humidity value. The MCU sends a control signal to the corresponding actuator to start or stop the compressor, fan, heater, etc.

Power Module

The power module converts the external AC power into the DC power required inside the cabinet dehumidifier, providing a stable power supply for each component.

Semiconductor condenser is a new type of condenser, which uses the thermoelectric effect of semiconductor materials to control the flow of refrigerant, thereby achieving precise control of the condensation process. Semiconductor condenser has been widely used in cabinet dehumidifiers, especially in occasions with high requirements for dehumidification accuracy, such as electronic equipment cabinets, precision instrument cabinets, etc. It can effectively prevent the generation of water vapor inside the equipment, thereby protecting the equipment from moisture damage.

External Cabinet Dehumidifier Construction

The external construction of enclosure dehumidifier includes shell, mask & control panel, connect terminals, and drain pipe.

Dehumidifier Shell

The shell of enclosure dehumidifier is made of durable and corrosion resistance materials. The most common material of enclosure dehumidifier is ABS, Aluminum Alloy, sheet metal and Stainless steel.

Mask and control panel

The mask of enclosure dehumidifiers covers the control panel to protect it from scratches, wear and contamination. It can clearly mark the function of each button to facilitate user operation. As for the control panel, the enclosure dehumidifier uses LCD screen so it can display data clearly for you.

Connect Terminals

The connect terminals are interfaces connecting the cabinet dehumidifier to external power sources and control devices, including power plugs, control panels, and communication interfaces. Terminals are compact design to ensure reliable and safe connection.

Drain-Pipe

The cabinet dehumidifier will produce a certain amount of water during operation, which needs to be discharged from the machine body to avoid water accumulation causing malfunction or affecting the dehumidification effect. The drain pipe is a pipe specially used to discharge this water.

Conclusion

According to enclosure dehumidifier construction, it showcases the intricacies of engineering technology, with various components working together to achieve efficient dehumidification. Internal components such as the fan, cooling fin, and circuit board ensure continuous and stable reduction of air humidity. Meanwhile, external components like the shell, mask, terminals, and drain-pipe provide necessary protection and support, ensuring the device operates reliably in various environments. Understanding these structures and principles not only helps in choosing and using the right dehumidifier but also provides guidance for daily maintenance, the thereby extending the device’s lifespan.
