When the machine is running continuously or under high load, it will overheat due to heat accumulation. This may not only lead to the decline of equipment performance and aging of parts, but also cause safety hazards and production stoppage losses. This article will introduce you to 6 effective ways to prevent equipment from overheating, helping you to improve the stability and service life of the equipment.

Ventilation and Heat Dissipation

Air can take away some of the heat generated by the machine. If your equipment is placed in a crowded and poorly ventilated place, the heat can build up faster than it dissipates, affecting its heat dissipation effect. You should avoid placing the machine against the wall or in a corner, leaving a suitable heat dissipation gap.

If space permits, it is best to install an exhaust fan or ventilation system around the equipment. Preventing the machine from overheating through ventilation is suitable for offices, laboratories, electronic workshops, control cabinets and other places with limited space.

Regular Cleaning

Dust and oil will adhere to the radiator, fan or filter of the machine. After long-term accumulation, a thick layer of stains will form, which will hinder heat exchange and increase the thermal load beyond safe levels. Even if the fan runs normally, it does not necessarily mean that the heat dissipation is good. After the thermal resistance increases, the temperature inside it will continue to rise.

Regular inspection and cleaning of the heat dissipation device can prevent this situation. Check the fan blades and radiator surface for dust accumulation every month, and replace or clean the air filter regularly. If you find frequent cleaning troublesome, you can use a dust cover or filter cotton to extend the cleaning cycle.

Intermittent Operation

When the machine is running continuously for a long time at full load, a large amount of heat is accumulated but cannot be dissipated as soon as possible, which can easily lead to thermal runaway. In particular, motors, lasers, vacuum pumps, etc. often have too fast temperature rise during continuous operation. Any machine should be allowed to have cooling recovery time. In high temperature environments, the operating frequency or operating power of the equipment should be appropriately reduced.

High Thermal Conductivity Materials

Good thermal conductive materials have high thermal conductivity efficiency and can dissipate heat to the outside of the equipment in time. When purchasing equipment, you can choose equipment with enhanced heat exchange design, and ask the manufacturer whether you can replace the aluminum or copper heat dissipation module, or use thermal grease or thermal pads to fill the contact gap.

Process Chiller

If you want a more stable and automated cooling method, you can choose a process chiller. This is a cooling system that relies on compressed refrigerant to generate cold. It is connected to the machine that needs to be cooled by a liquid supply pipe and a liquid return pipe. After the chiller removes heat from the coolant (such as water or ethylene glycol), it will transport the low-temperature coolant to the inside of the equipment through the liquid outlet to take away the heat of the equipment. Then it returns to the chiller through the liquid return port and waits to be cooled again.

This process is automatic, and the chiller will adjust the cooling capacity according to the temperature of the equipment to achieve automatic, stable and efficient temperature control. You can also customize multi-channel, multi-temperature zone, and explosion-proof functions according to cooling needs. It is very suitable for lasers, semiconductor equipment, experimental reactors, battery testing, power supply systems, etc.

Early Warning and Safety Devices

You can add temperature sensors, infrared thermometers, and set high temperature alarm values to monitor temperature changes in real time. The machine can automatically shut down when the set value is exceeded to prevent the equipment from being damaged by overheating. Some industrial systems support interlock control, which can automatically cut off the power, turn on cooling, or start the backup system when overheating.
