1. Field of the Invention
The present invention relates to a cooling system, and in particular relates to a magnetic cooling system utilizing a magnetic valve unit.
2. Description of the Related Art
In magnetic cooling systems, recycled water travels therein to transmit heat generated by a working material. Conventionally, electromagnetic valves or mechanical valves are utilized to control the flow paths of the recycled water. When a magnetic cooling material is in a magnetic field, the valves (electromagnetic valves or mechanical valves) control the recycled water to travel between a heat transfer means and the working material. When the magnetic cooling material is not in the magnetic field, the valves control the recycled water to travel between a cool transfer means and the working material. For conventional magnetic cooling systems, however, reliability of mechanical valves therein is not high, as mechanical valves wear out easily. Also, mechanical valves generate heat, require a relatively large amount of power, and are relatively expensive. As for electromagnetic valves, they also generate heat, are relatively large in size, and are also relatively expensive.

A cooling system is provided. The cooling system includes a heat transfer means, a cool transfer means, and a magnetic-cooler. The magnetic-cooler includes a first magnetic member, a second magnetic member, a bed and a magnetic valve unit. The bed includes a working material, wherein the bed rotates between a first position and a second position. Also, when the bed is in the first position, the working material is magnetized, and when the bed is in the second position, the working material is demagnetized. When the bed is in the first position, the magnetic valve unit controls a first fluid to travel along a first path between the heat transfer means and the working material, and when the bed is in the second position, the magnetic valve unit controls a second fluid travel along a second path between the cool transfer means and the working material.
