Abstract

Abstract An improved temperature gradient and moisture regulator for electrically ered apparatus and the like is disclosed as comprising an insulated mount for supporting the apparatus whose temperature gradient and moisture is to be controlled. A thermoelectric cooler is located in effective contact with both a certain substantially central surface area of said apparatus where the cooling thereof is to be effected and one end area of an elongated heat pipe. A plurality of thermoelectric heaters is also disposed in contact with such surface areas of said apparatus as are located in predetermined spatial proximity with the aforesaid cool surface area, thereby creating a heating effect thereat for moisture control purposes. Both predetermined cooled and heated areas are caused to occur at various surface locations where the temperature gradients thereof are to be controlled. Several other cooling sources may optionally be connected to the other end area of the aforesaid heat pipe, either individually or in concert, so as to increase the cooling efficiency of the invention.
