The Peltier-Technology What are the advantages of cooling with Peltier cooling components? Which differences and similarities to conventional compressor systems exists? Both cooling systems have a heat flow from a cold to a warm reservoir. In the compressor system, the heat transfer is carried out by a cooling fluid, which is compressed by the compressor and transported through the system. In the Peltier-Cooler System, the electric current corresponds to the coolant of the compressor and the direct current voltage source is equivalent to the compressor. A variety of applications can only be solved...

Examples Mini Dehumidifier For reducing the humidity in laser heads, we developed a water-recooled mini dehumidifier for a customer consisting of a special copper heat exchanger and an integrated condensate drainage channel. The active ventilation of the condensate plate also increases the dehumidifying performance and at the same time generates a gentle air movement inside the laser head. The module is held in its ideal operating point via an external control, which we also developed, in order to provide efficient dehumidification of the laser head. Active Camera Cooling Due to the food industries...

Switch Cabinet

The principle of Peltier cooling is similar to that of an electronic heat pump. The Peltier elements transfer thermal energy from the cold exchanger to the switch cabinet interior to the heat exchanger on the switch cabinet exterior. The warm air inside the switch cabinet is blown onto the cold exchanger by a fan and thereby cooled. The heat exchanger on the switch cabinets exterior is then re-cooled by ambient air. The advantage of Peltier cooling is its functional reliability. In addition, our switch cabinet coolers can be used in moving or accelerating systems. All Dr. Neumann switch cabinet...

SERIE STANDARD Performance Curves The performance diagrams of our coolers show the results of a long series of in-house tests for every single device type. They depict the exact performance of a cooler relative to the ambient temperature and internal temperature of the switching cabinet. For the layout design, the operating point is first assumed, which means that the cooling capacity of the Peltier device corresponds exactly with dissipation loss in the cabinet. That keeps the internal temperature stable. In order to determine this, the power loss is first marked on the X-axis of the diagram...

Switch Cabinet Cooler

SERIES „STANDARD“ The “Standard” series switch cabinet coolers are available in three sizes with three power grades each. They distinguish themselves with their compact designs and very high efficiency and offer superior performance despite their small size. All “Standard” series switch cabinet coolers are fitted with protection against overheating and alarm relays. The exterior has been designed to provide IP67 prot

Switch Cabinet Cooler

The “AC” series switch cabinet coolers are available in three sizes with two power grades each. They have built-in power supplies on the outside of the units. The devices of the “AC” Series can be operated with mains voltage and there is no extra power loss inside the cabinet to operate the Peltier cooler. All “AC” series switch cabinet coolers are fitted with protection against overheating and alarm relays. The exterior has been designed to provide IP67 protection. The units of the “AC” series are only suitable for cooling. However, a version for switching between cooling and heating is availa...

High-Temperature Cabinet Cooler

The high-temperature cabinet cooler series “HL” cools efficiently – even at high operating temperatures of up to 90 °C. Three models in three different sizes with the nominal input of 50 W 100 W and 200 W deal with demanding cooling tasks in an operating temperature range between -40 °C and +90 °C. The environmental protection class IP67 guarantees optimal protection against ambient, despite high temperatures. The “HL” cabinet coolers are equal in size and pin compatible to our “Stand
