Bendable water cooling device

The invention relates to a water-cooling device which can be bent, in particular to a water-cooling device which has the function of bending and can be arbitrarily arranged according to the existing space in the electronic device.

In the operation of an electronic device, the heat generated during the operation of the CPU or other processor must be quickly and efficiently dissipated. At present, the cooling means widely used for CPU or other processors is mainly air-cooling devices, mainly using a bulk device and a fan as a means of heat dissipation. Another type of cooling system is used to cool a CPU or other processor. Such a water-cooling technique, such as U.S. Patent No. 8,245,764 (US Pat. No. 8,245,764), discloses a cooling system for a heating element, comprising: a double-sided base for accommodating a pump a pump for circulating a cooling liquid, the pump comprising a stator and a pusher, the pusher being disposed on a bottom side of the base, the stator being disposed on a top side of the base to be isolated from the cooling and cooling liquid; a liquid storage chamber Providing the cooling liquid therethrough, the liquid storage chamber comprising: a pumping chamber including the pusher and formed under the base, at least one pusher cover defining the pumping chamber, and having One or more flow passages for circulating the cooling and cooling liquid; a heat exchange chamber formed below the pump chamber and vertically spaced from the pump chamber, the pump chamber and the heat exchange chamber Separating chambers and flowing together through the one or more channels; a heat exchange interface forming one of the heat exchange chambers a side edge and in contact with a heating element; and a heat sink connected to the liquid storage chamber to dissipate the cooling liquid. In another example, the electronic device includes a pumping housing having a heating element, a heat dissipating portion for dissipating heat to the heating element, and a pumping unit having a pusher and a pumping unit. The heat absorbing portion is configured to thermally connect the heat generating component, wherein the pumping unit supplies cooling liquid to the heat radiating portion by the rotation of the pusher, and the cooling liquid circulates in a circulation path between the heat absorbing portion and the heat radiating portion to The heat generated by the heat generating element is transmitted to the heat radiating portion through the cooling liquid. The center of the pusher of the pump unit is disposed separately from the center of the heat generating component. Since the conventional liquid storage housing and the pump unit have many parts, and the parts are directly assembled in a single double and the inside of the base, and two chambers vertically separated from each other must be separated, the structure cannot make the liquid storage.
