Phase conversion cooler and mobile equipment

Abstract

A small and lightweight phase conversion cooler having high cooling efficiency and mobile equipment. The phase conversion cooler has a cooling head having a first side in contact with a cooled object, a first circular port provided in a second side, a second circular port provided in a third side, a first pipe connected to the first circular port, a condenser part placed in a heat dissipation environment and a second pipe connected to the second circular port. The cooling head is formed by resin molding. The first side of the cooling head is provided with a metal plate.

1 . A phase conversion cooler comprising:
 a cooling head having a first side to contact an object to be cooled and contain a refrigerant therein;   a first circular port for discharging the refrigerant out of the cooling head, the first circular port being provided to a second side not opposite to the first side of the cooling head;   a second circular port for taking in the refrigerant, the second circular port being provide to a third side not opposite to the first side and the second side of the cooling head;   a first pipe whose one end is connected to the first circular port, the first pipe being a part of a circular pipe;   a condenser part connected to the other end of the first pipe and placed in a heat dissipation environment; and   a second pipe whose one end is connected to the condenser part and the other end is connected to the second circular port, the second pipe being a part of the circular pipe,   wherein the cooling head is formed by resin molding housing and a metal plate, and at least a part of the first side of the cooling head is formed with a metal plate.   
     
     
         2 . The phase conversion cooler according to  claim 1 , wherein:
 in addition to the metal plate of the first side, at least one of sides other than the first side of the cooling head is provided with a metal plate.   
     
     
         3 . The phase conversion cooler according to  claim 2 , wherein:
 the metal plate of the first side is contact with the other metal plate of at least one of sides other than the first side of the cooling head is in contact with each other.   
     
     
         4 . The phase conversion cooler according to  claim 2 , wherein:
 the other metal plate of at least one of sides other than the first side of the cooling head is provided on an inner surface of the cooling head.   
     
     
         5 . The phase conversion cooler according to  claim 1 , wherein:
 the first side of the resin mold housing of the cooling head comprises a resin-free portion closed with the metal plate.   
     
     
         6 . The phase conversion cooler according to  claim 1 , wherein:
 the metal plate comprises a protrusion anchored into the resin molding housing.   
     
     
         7 . The phase conversion cooler according to  claim 1 , wherein:
 the metal plate is provided to the resin molding housing of the cooling head by insert molding.   
     
     
         8 . The phase conversion cooler according to  claim 1 , wherein:
 the second pipe has a portion inclined toward the side of the first pipe.   
     
     
         9 . The phase conversion cooler according to  claim 1 , wherein:
 when the cooling head stands at that the first side of the cooling head is positioned as an under side of the cooling head, a height of the first circular port and that of the second circular port are different from each other in a vertical direction.   
     
     
         10 . Mobile equipment provided with the phase conversion cooler constructed by any one of  claims 1  to  9 .
