7 Tips for Temperature Control of Electrical Enclosures

The temperature of equipment in electrical enclosures must be controlled to avoid the risk of equipment failure due to overheating. In most cases, some form of enclosure temperature control is needed.

These seven tips can help you assess your temperature control systems. Although enclosures dissipate heat, the total heat load in many instances exceeds the rate at which this heat can be dissipated, and the internal enclosure temperature may exceed the maximum temperature limits of the equipment.

Heat Pipe Technology in Enclosure Cooling: Why You Need It

Air to air heat exchangers use an innovative heat pipe technology that is simple, effective, and reliable. It's ideal for situations where cooling is required for sealed enclosures when alternative methods of cooling, such as filtered fans or air conditioning, are not desirable or practical.

The heat pipe, the heart of an air to air heat exchanger, uses the evaporation of a refrigerant liquid to transfer heat from the bottom to the top of the heat pipe, where the heat is discharged to the ambient air. Aluminum fins are attached to the pipe to improve the conduction of heat; a vertically mounted tube simplifies the design, increases capacity, and ensures reliability. The only power required is for two air circulation fans: one to circulate cool air to the electrical enclosure and the other to remove hot air from the top of the heat pipe and discharge this heat to the environment.

Here are several reasons why you should consider heat pipe technology.

5 Temperature Control Solutions for an Electrical Cabinet

The most common reason for reduced efficiency, malfunctioning and failure of electrical equipment is
high temperature . Electrical equipment such as variable speed drives and PLCs are designed to work within a particular temperature range. It is reported by Schneider that a 10°C increase in temperature could halve the life of the equipment. Therefore, it is imperative that the enclosure that houses the electrical equipment be designed with thermal management solutions in mind. A small investment in temperature control solutions could result in increased uptime and lower maintenance issues, improved efficiency of equipment and an increase in overall productivity for your business.

How Condensation Management Keeps Equipment Safe

Condensation and electricity are a potentially deadly mix because moisture significantly increases the dangers of electric shock. It's for this reason that it is essential that any condensation forming inside an electrical enclosure is removed. Traditional methods of condensate removal are not particularly effective and if poorly installed may lead to spillage of water around the enclosure.

In addition to the increased risk of electric shock, condensation may cause corrosion and damage electrical equipment. It is vital to choose an enclosure air conditioner supplier that incorporates effective condensate removal methods as a standard feature in their enclosure air conditioners.

Advantages of a Thermal Expansion Valve in Enclosure Cooling

The thermal expansion valve is a throttling device that allows the refrigerant in an enclosure air conditioner to expand. A phase-changing refrigerant is circulated in the air conditioner through the compressor, condenser and evaporator. The expansion valve controls the flow of the liquid refrigerant into the evaporator where it gets converted into a gas upon absorbing the heat from the enclosed space. Older designs used a passive capillary tube to allow uniform expansion of the refrigerant, while modern air conditioners use an active thermal expansion valve that changes the rate of throttling of the refrigerant based on the heat load.
