Patent

CA 2394474

A refrigerator includes a housing that defines an enclosable storage space. The refrigerator includes a closed manifold which defines a chamber to contain refrigerant. The chamber is made up of three parts, a cooling pipe, a head pipe, and one or more heat pipes to communicate fluid between the cooling and head pipes. The heat pipes are flat, elongated, and are divided internally to form capillary channels to permit flow of refrigerant between the cooling and head pipes. An array of thermoelectric modules contacts a surface of the manifold to chill refrigerant within the manifold. A pump or compressor is not required to circulate the refrigerant within the system. A blower forces an air stream to cool the heating faces of the thermoelectric modules. A control unit may be used to maintain the operating temperature of the refrigerator. A refrigerator may be portable, with a portable power source or adapters. The manifold design is useful for modular refrigerator appliance designs. The manifold is also useful in other refrigerating systems, cold storage units and portable devices.
