## Abstract

A cooling head for a temperature-controlled phase change cooler has a main body, an evaporating chamber within the main body, at least two cap tubes and at least a heat source mounted onto the periphery of the evaporating chamber. With one of the cap tubes, the coolant is guided into the evaporating chamber, then the cooling head of the phase change cooler could be quickly cooled clown due to rapid heat absorption characteristic of the evaporated coolant. In such a case, a heat source is used for heating by a control mechanism, and the temperature could be adjusted to a desired temperature point within the limited range of low temperature according to the user demands. When the preset temperature point is higher than normal temperature, the control mechanism could change properly the flux via one of two cap tubes, and provide proper amount of coolant for evaporative cooling.

## Claims

### Claim 1

A cooling head for a temperature-control phase change cooler comprising:
a main body;
an evaporating chamber within the main body;
at least two flow-controlled cap tubes; and
at least one heat source mounted onto the periphery of the evaporating chamber.

### Claim 2 (depends on 1)

The cooling head of claim 1, wherein said heat source is an electric heating tube, which is inserted into at least one slot of the main body.

### Claim 3 (depends on 1)

The cooling head of claim 1, wherein said heat source is an electric heating strip, which is covered securely onto the periphery of the evaporating chamber.

### Claim 4 (depends on 1)

The cooling head of claim 1, wherein said cap tube is linked to the flow controller for flow control, and there are at least two cap tubes.
