Abstract: A switchable bidirectional core-actuated valve is provided with a chamber, and a first shaft hole, a second shaft hole and an output hole communicating with the chamber. The chamber is received therein with a non-return valve able to move in the chamber. Thus, water cooling liquid can make use of water pressure to have the non-return valve moving to a first position or a second position. When the non-return valve is at the first position, the first shaft hole will communicate with the output hole, when at the second position, the second shaft hole will communicate with the output hole. Thus, water cooling liquid can get into the chamber through the first shaft hole or the second shaft hole and then flow out of the output hole.

Abstract: A water cooling device capable of switching a pump loop is provided. The water cooling device sends a liquid coolant through a first pump or a second pump and moves a shuttle valve to a first position or a second position, so that the liquid coolant can flow into the shuttle valve from different directions and then flow out from an output hole. The shuttle check does not consume power, but also can achieve the non-return function. Then, the liquid coolant flows into a water block to cool a load. After that, the liquid coolant flows to a radiator fan for heat dissipation and then flows to the water tank for circulation, achieving the effect of bidirectionally switching the pump loop. The water cooling device can continue to operate without stopping.

Abstract: A water cooling device includes a radiator provided with a radiating member and connected with a water tank, which is connected with a first pump and a second pump. The first pump and the second pump can be actuated to operate by turns so that the first pump and the second pump can alternately have the cooling liquid in the water tank conveyed to an endothermic water cooling head for cooling off a heating element. The water cooling device of this invention is able to attain effect of continuous operation without interruption.

Abstract: A heat absorbing device includes a converter, a heat semi-conductor located on the converter, a cool guide plate placed on the heat semi-conductor, and a moisture-proof cap provided with a recessed accommodating space for receiving the heat converter and the heat semi-conductor. The moisture-proof cap has an upper opening that the cool guide plate is fitted closely in, and a combining mouth formed in its bottom for the combining member of the heat converter fitted closely therein, insulating the heat semi-conductor from exterior air.
