Liquid cooled thermal platforms or LCTPs use a single phase heat transfer fluid to add to or remove heat from the thermal plate. They are connected to a source of conditioned (cooled and or heated) fluid. The conditioned fluid usually comes from a portable or stationary re-circulating chiller or plant chilled water (PCW) source. LCTPs are often used in long term component burn-in test applications that benefit from the cost savings realized by using a re-circulated fluid instead of a consumable refrigerant like LN2 or LCO2 used in CCTPs.
They are also more flexible in applications that require connection and disconnection of the thermal platform from the cooling source. Something that is not possible with direct expansion mechanically refrigerated systems like the MRTP. Because the LCTP utilizes a single phase liquid to transfer the heat, special care is given to the design of the fluid circuits to insure good thermal uniformity and stability over the entire surface of the thermal platform. LCTPs can be furnished as a stand alone thermal platform or as a complete system including temperature and fluid controls. They can also be supplied with our without electric resistance heating elements.
