Abstract

The invention's metering CO2 releasing system may be triggered by an electronic or a thermostatic valve or may be triggered manually or by an electronic solenoid.

First claim

What is claimed is:

1. A cooling system comprising:
a. at least one CO 2 container retaining CO 2 therein;
b. a flat plate having a flat plate top surface and a flat plate bottom surface that are connected by a flat plate vertical wall surrounding a perimeter of the flat plate;
c. a distance between the flat plate top surface and the flat plate bottom surface large enough to retains a multiplicity of tubing routes with a multiplicity of capillary tubes, a respective one of each of the multiplicity of capillary tubes retained with a respective one of the multiplicity of tubing routes;
d. a manifold block, said CO 2 container connected to said manifold block by a flexible discharge line that connects said CO 2 container through a manifold block hole in the manifold block;
e. a solenoid valve positioned on the manifold block and controlling an amount of CO 2 entering the manifold block from the CO 2 container;
f. the manifold block in fluid communication with said multiplicity of capillary tubes;
g. each respective one of said multiplicity of capillary tubes having an outer both that surrounds an opening that extends from a first end opening of each respective one of the multiplicity of capillary tubes to a second end opening of each respective one of the multiplicity of capillary tubes; and
h. said CO 2 transported to said multiplicity of capillary tubes and transmitting cooling through conduction to objects placed on the flat plate top surface.

2. The cooling system in accordance with claim 1 , further comprising: each of said outer body of each respective one of said multiplicity of capillary tubes bent at an angle at a location adjacent each respective first opening for fluid connection to said manifold block.

3. The cooling system in accordance with claim 1 , further comprising: said solenoid valve is an electronic solenoid valve.

4. The cooling system in accordance with claim 3 , further comprising:
a. said manifold block includes said electronic solenoid valve, a pre-load spring, a shaft, a plunger, a lever hinge pin and an actuator lever;
b. when said electronic solenoid valve is closed, said plunger return spring holds said plunger against an orifice of said CO 2 container, preventing flow of CO 2 through said electronic solenoid valve; and
c. when said electronic solenoid valve is energized, a magnetic field is produced, actuating said actuator lever and in turn raising said plunger and allowing CO 2 to flow through said electronic solenoid valve.

5. The cooling system in accordance with claim 1 , further comprising: said CO 2 is selected from the group consisting of liquid and gas.
