Micro Cooling System


Product Introduce

HZSS is one of the first companies who started to R&D micro compression-expansion cooling systems. Since 2010, HZSS devoted ourself to micro compression-expansion cooling systems. Now HZSS' products have been widely used in body cooling(heating), medical cold compress, portable/vehicular cooling system, test instruments, high precision temperature controlling etc.

On the other side, HZSS also have solution for semi-conductor cooling products.

Product Principle


HZSS micro compression-expansion cooling products adopt compression refrigeration cycle theory for cooling and some of them also can be used for heating. The systems consist of thermal dissipation, compression cooling system, liquid/air temperature controlling system and control system. Liquid/air temperature circulation system absorb and take heat which may come from human body, electronics, enviroment or other place to evaporator that has refrigerant circulation in it of compression system. In compression cooling system, refrigerant cyclically move through compressor and throttling device and take heat to condenser of thermal dissipation system. In thermal dissipation system, heat is dissipate to enviroment or cold water. Using PTC eletric heating or electric resistance wire heating, temperature controlling system increase the temperature of heat source, at this time compression cooling system and thermal dissipation system will not work; Using heat pump priciple for heating, these machine will work according to reverse-cooling system. Controlling system will set the parameters, control temperature and protection the other 3 systems(thermal dissipation, compression cooling system, liquid/air temperature controlling system).

Features


① Small and light:

When comparing with related products HZSS micro compression-expansoion cooling products are the most small and most light ones. HZSS micro cooling system are widely used in aerospace, vehicle-mounted, small space, portable conditions that have special requirments for small size, low weight and high power density.

② High thermal density:

HZSS micro cooling system has excellent thermal dissipation and cooling ability.

③ High COP:

The COP of micro cooling system is about 2.0, which is 5 times that of semiconductor cooling device, and much higher than other refrigeration ways. Because of high COP, they will need smaller room for heat dissiaption.

④ Easy for controlling:

Liquid connector, electronic joints all are quick coupling. And all parameters can be set on the display pannel. If needed, these products can communite with upper computer to set parameters and share data in real time.

⑤ Precisely control temperature:

Depending on continuously variable transmission of compressor, fan, pump and our controlling algorithm, we can control temperature with erro of ±0.2 °C or ±0.1 °C.

⑥ Reliable and safety:

Products have passed through many kinds of reliability and safety test, like vibration, pressure, barometric pressure, temperature, oil return, condensation, weather ability, reliability of liquid pump/fan and so on. Before ex-factory every products will be test, they can also be test of EMC according customers demands.

⑦ Excellent enviroment adaptation:

  • (1) Cooling or heating in temperature of 50 ℃~-40℃. Temperature can be continuously controlled from -20℃~ 35℃.
  • (2) Adapt to 0.5 ~ 1 atmospheric pressure (high altitude) working environment.
  • (3) Response quickly according to temperature changing.
  • (4) Adapt to mobile sloshing environment (transportation, people carry).
  • (5) According to the requirements, it have the corresponding level of waterproof and dustproof function, electromagnetic compatibility, medical device certification.

⑧ Smart:

Products will self diagnosis there main parts and key functions, and some of them can self-recovery, if some thing wrong happened.

Some products can be controlled remote
