  • RIGID DC LIQUID CHILLER

    Compact and Reliable Small Liquid Cooling Solutions

    WHAT’S RIGID LIQUID CHILLER?

    Liquid Chiller cooling refers to cooling by means of the convection or circulation of a liquid. It is a method of heat removal from components and devices. As opposed to air cooling, liquid is used as the heat conductor.

     

    Usually, water is the best best heat conductor. Water cooling is commonly used for cooling precise instrument, laser, lab test. Recently, small water chiller also is used for various major components cooling.

     

    For example, it is applied to inside high-end personal computers such as CPU, GPU, and motherboards. The main mechanism for water cooling is convective heat transfer. It includes:

     

    • Water cooling  
    • Liquid cooling for computers
    • Cooling by convection or circulation of coolant
    • Liquid Cooling and Body Vest Cooling
    • Laser and Precise Instrument Cooling

    HOW’S RIGID LIQUID CHILLER MODULES?

    RIGID liquid chiller module is an integrated cooling sub-system. It is specially used for small footprint cooling applications where space and weight are critical.

     

    The LCM includes Miniature Compressor, Driver Board, Condenser, Evaporator and other small cooling parts. It provides core cooling and refrigerant control mode is capillary tube. This subsystem is full charged with R134a and oil and ready to use. It allows end users to adapt to the coolant fittings for ultimate flexibility.

     

    RIGID liquid chiller module is world’s lightest weight and very compact footprint. It particularly designed for small liquid circulatory cooling, such as laser manufacturers, laboratory, hospital lab, large end users and system integrators.

     

    RIGID patent mini dc compressor drives the refrigerant directly through the heat exchangers. This concept eliminates the need for a water cooling loop (water pump, reservoir and associated tubing) resulting in a greatly simplified cooling system.

    WHY RIGID DEVELOP LIQUID CHILLER MODULE?

    To meet the growing demand of small cooling systems, RIGID has developed compact liquid chiller modules for several customers. At first, these compact cooling modules are used for portable and compact water chiller and small device cooling.

     

    Later, They are widely used in medical, aesthetic, laboratory, military who expressed a need for a compact, lightweight liquid chiller, which would meet the environmental stresses of the harshest environments while still provided sufficient cooling or heating. The system has both heating and cooling capabilities and circulates thermally regulated (+/- 0.5°C) coolant to a customer cold plate or heat exchanger.

     

    The system has a built-in pump and reservoir to circulate the coolant, which allows system to function without the use of a fill kit. The system also has a communication port which allows the user to monitor the system performance and choose the operating temperature.

     

    The compact design gives the user flexibility to design this chiller into their system or have is reside as a separate unit. Also, the cold plate, which ultimately removes heat from the payload, can exist remotely from the chiller and can be designed as appropriate.

     

    The chiller has been designed to meet the requirements of mobile applications where it may besubjected to shock, vibration, and a variety of environmental conditions.

    HOW RIGID SMALL COOLING SYSTEM WORK?

    RIGID liquid chiller systems offer high heat transfer rates because the R134a refrigerant has a high thermal conductivity and heat-absorption capacity. Our liquid chiller systems are quite compact because of our patent miniature dc compressor. The mini compressor circulates R134A refrigerant which takes away heat from heat source dramatically.

     

    RIGID liquid chillers are ideal for cooling high heat flux components and in applications where a solution must be rugged and reliable. It is also a better cooling solution for small liquid cooling where space and weight are critical fators.
