First, application scenarios involved in embodiments of the present disclosure are introduced below.

A cooling device provided by embodiments of the present disclosure may be applied to any scenario where a to-be-cooled component needs to be cooled, for example, for certain electronic components, such as chips. Because the chips (especially data processing chips with high hash rate) may continue to generate relatively large heat during operation, a corresponding cooling device may need to be equipped to absorb the heat generated by the chips to cool the chips.

In embodiments of the present disclosure, the cooling device may cool a hashboard, especially a plurality of data processing chips included in the hashboard.

For example, generation of a digital voucher requires a large amount of computation, which requires a processing apparatus of the digital voucher to be equipped with professional processing chips. Chip density of the processing apparatus of the digital voucher is high. The processing chips may generate relatively large heat during operation. Therefore, heat dissipation and cooling may need to be performed immediately.

When the digital voucher is related to or embodied as digital currency, the processing apparatus of the digital voucher may include a digital currency mining machine. The digital currency may include encrypted currency such as Bitcoin.

In the cooling device of embodiments of the present disclosure, the cooling liquid is contained inside the cooling device. After the cooling liquid is transformed into a gas by absorbing the heat of the to-be-cooled component, the gas may be converted into the liquid by the heat dissipation assembly to realize cooling of the to-be-cooled component. Cooling efficiency may be high. The cooling liquid may be circulated and used.

The technical solution shown in the present disclosure is described in detail through embodiments of the present disclosure below.

The following embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

<FIG> is a schematic front view structural diagram of a cooling device according to an embodiment of the present disclosure. As shown in <FIG>, embodiments of the present disclosure provide a cooling device <NUM>. The cooling device <NUM> includes a housing <NUM> and a heat dissipation assembly <NUM>. A sealed space, which can accommodate cooling liquid, is formed inside the housing <NUM>. The cooling liquid may contact the to-be-cooled component. The heat dissipation assembly <NUM> includes a heat dissipation assembly body <NUM> and a heat conducting pipe <NUM> communicated to the heat dissipation assembly body <NUM>. The heat dissipation assembly <NUM> is arranged in the sealed space formed by the housing <NUM>. The heat dissipation assembly body <NUM> may be configured to absorb the heat of the gas to covert the gas into the liquid after the cooling liquid transforms into the gas by absorbing the heat of the to-be-cooled component. The heat conducting pipe <NUM> may be at least partially located outside the housing <NUM>.

As shown in <FIG>, the heat dissipation assembly body <NUM> may be arranged at <NUM>/<NUM> to <NUM>/<NUM> position of the housing <NUM> along a height direction (a direction indicated by arrow H in <FIG>). The heat dissipation assembly body <NUM> may divide the sealed space formed by the housing <NUM> into a first space <NUM>, which may be configured to accommodate the cooling liquid and the to-be-cooled component, and a second space <NUM>, which may be configured to maintain the pressure.

For example, the first space <NUM> containing the cooling liquid is located at the bottom of the housing. For example, the cooling liquid may be contained in one or more containers. Each container may accommodate one or more to-be-cooled components. Alternatively, the cooling liquid may be placed directly in the first space <NUM>.

In an embodiment of the present disclosure, the bottom of the container may occupy the entire bottom of the housing <NUM> or only a portion of the bottom of the housing <NUM>, which is not limited by the present disclosure.

In some embodiments, the first space <NUM> may contain the cooling liquid. The to-be-cooled component may be placed in the cooling liquid. The whole or a portion of the to-be-cooled component may be in contact with the cooling liquid. The cooling liquid may absorb heat from the to-be-cooled component. After the temperature of the cooling liquid reaches a boiling point, the cooling liquid may vaporize into the gas.

The heat dissipation assembly body <NUM> may not be in contact with the cooling liquid. After the cooling liquid transforms into the gas, the heat dissipation assembly body <NUM> may absorb the heat of the gas. The hot gas may liquefy into the liquid when meeting the cold heat dissipation assembly body <NUM>. The liquid may flow into the sealed space formed by the housing <NUM> under the action of gravity so as to realize the circulation of the cooling liquid. While absorbing the heat, the heat dissipation assembly body <NUM> may exchange heat with the outside of the housing through the heat conducting pipe <NUM> communicating with the heat dissipation assembly body <NUM>. Thus, the heat dissipation assembly may absorb heat continuously.

In other embodiments of the present disclosure, if the to-be-cooled component is a hashboard, and the hashboard includes a plurality of data processing chips, the cooling liquid may be an insulation liquid. The cooling liquid may not affect the operation of the data processing chips. The data processing chips may be placed in the cooling liquid for cooling during the operation.

In other embodiments of the present disclosure, the cooling liquid may include a liquid with a lower boiling point, for example, the boiling point of the cooling liquid may be lower than a certain preset threshold. The cooling liquid with the lower boiling point may be easy to vaporize and absorb the heat faster. The cooling efficiency may be higher. The cooling liquid is, for example, a fluorinated liquid. The preset threshold may include, for example, <NUM>, <NUM>, <NUM>, and <NUM> Celsius degrees. The suitable cooling liquid may be selected according to the actual situation, which is not limited by the present disclosure.

The container body <NUM> and the cover plate may be sealed by a seal member, so that a sealed space may be formed inside the housing. In the cooling device, dust may not be accumulated, and no noise may be generated during the cooling process of the to-be-cooled component.

The seal member may include, for example, a seal ring made of silicone gel.

Then, the heat-exchange liquid may flow from the second container <NUM> to the other portion of the pipes to flow to the first container <NUM>. Thus, the heat-exchange liquid may be circulated in the first container <NUM>, the cooling pipe <NUM>, and the second container <NUM>.
