Heat dissipation for confined space
separated cooling system

This product is a refrigeration system with a refrigerating capacity of 400W, it is designed with split thin section (inner machine height less than 40mm), so as to occupy the precious space as much as possible in the equipment. Inner and outer machine connector both use full sealed quick joint. The inner machine has no water design, and it can carry out self-control without condensate water.

1. Product features

①Small size and light weight: The thickness of the inner machine is only 40mm, and the outer machine adopts a slender structure to facilitate the installation and layout in the narrow space.	②High refrigerating capacity: When the ambient temperature is 40 degrees centigrade and the temperature is 25 degrees in the equipment space, the refrigerating capacity is 400W. (The higher the ambient temperature is, the lower the refrigerating capacity is, and the lower the room temperature is, the lower the refrigerating capacity is).
③High efficiency: The refrigeration efficiency of the small micro refrigeration system is about 2, which is 5 times of the semiconductor refrigeration efficiency, and is far higher than other refrigeration and cooling methods.	④Easy operation: The refrigerant connection and electrical connection of the product are both plugged by the quick connector.
⑤High temperature control accuracy： The temperature can be manually set on the touch screen, and the product can achieve the temperature control accuracy of 1 degrees centigrade.	⑥High reliability and safety: product development through a series of reliability and safety testing. The factory production of each product must go through the corresponding type test (vibration, pressure, high and low temperature environment, weather resistance, oil return, condensation, protection, liquid pump / fan components such as reliability, performance, electrical safety etc.).
⑦Good environmental adoptability: a.Adapt to mobile sloshing environment (transportation, people carry). b.Adapt to 0.5 ~ 1 atmospheric pressure (high altitude) working environment. c.According to the requirements, it have the corresponding level of waterproof and dustproof function, electromagnetic compatibility, medical device certification.
