Refrigeration system

A cooling device for dissipating heat from an electronic component, comprising:

• an evaporator disposed next to said electronic component to thermally contact with said electronic component, said evaporator defining therein a fluid flow channel for passage of a refrigerant fluid and transmission of said heat to said refrigerant fluid so as to remove said heat from said electronic component via said refrigerant fluid;
• a refrigeration system in communication with said fluid flow channel of said evaporator to receive said refrigerant fluid from said fluid flow channel for removal of said heat and to return said refrigerant fluid back to said fluid flow channel;
• and
• a clamping member installed next to said evaporator and comprising portions to fix communication parts of said evaporator and said refrigeration system in position, at least one abutting portion extending from said clamping member toward said evaporator around said communication parts of said evaporator and establishing a surface engagement with said evaporator in said evaporator so as to exert force onto said evaporator to maintain intimate thermal contact of said evaporator and said electronic component.

A cooling device for an electronic component mounted on a circuit board, the cooling device comprising:

• a housing member mounted on the circuit board and housing the electronic component therein;
• an evaporator accommodated in the housing member and thermally contacting with the electronic component, the evaporator defining a fluid flow passage adjacent the electronic component;
• a clamping member attached to the housing member to hermetially enclose the evaporator and the electronic component in the housing member;
• a refrigeration system comprising an outlet tube and an capillary tube in fluid communication with the fluid flow passage of the evaporator;
• and
• an abutting element located apart from the outlet tube and connected between the clamping member and the evaporator for exerting an uniform force to the evaporator to thereby maintain the evaporator firmly contacting with the electronic component.
