Cooling sub-assemblies with thermoelectric element(s), coupling clamps, hot side and cold side heat exchanger having a direct insertion or removal of cooling modules onto a fixed mounting frame arranged in rows and columns to produce desired and required cooling levels.

The present invention provides a cooling device, comprising a first cooling portion, a second cooling portion, and a first receiving cavity sandwiched between the first cooling portion and the second cooling portion, where the first cooling portion is disposed around the second cooling portion, and the first cooling portion and the second cooling portion are distributed spaced-apart. According to the present invention, the liquid to be cooled in the first receiving cavity is simultaneously cooled by the first cooling portion and the second cooling portion without an additive being added, so that the cooling effect is substantially improved.

Proposed is a filter fixing module mounted to a handpiece cooling device having a connecting unit such that a refrigerant supply unit is coupled thereto, the filter fixing module including a body having a support surface formed in a plate shape, and a receiving surface formed on an edge of the support surface and protruding in a first direction relative to the support surface so as to prevent removal of a filter received in the support surface, and a grip unit connected to the body, wherein the grip unit comprises a first grip member and a second grip member extending in directions opposite to the protruding direction of the receiving surface relative to the body.

A special-shaped tube cooling and heat dissipation system includes a cooling module including a cooling chip, a liquid cooling tube, a cooling fin block and a first fan for generating cold air, a heat dissipation module including a radiator with heat pipes and a second fan, and a piping system. Through the piping system, the heat of the cooling module is transported to the radiator through the liquid, and then the heat in the liquid is discharged, and the liquid is recirculated back to the cooling module. The liquid cooling pipe and the heat pipes are flat tubes extruded from aluminum alloy to increase the heat dissipation area, each defining therein a plurality of flow channels. The liquid cooling tube and the heat pipes are respectively combined with flow guide devices that connect the heat pipes in series to form a circulating heat dissipation flow channel.

An ice maker and a refrigerator having same. The ice maker comprises: a cooling part having a heat dissipation device and a metal piece; a liquid container configured to store liquid; a liquid supply part configured to supply liquid to the liquid container; a moving mechanism configured to rotate and move the liquid container; and a control part. The metal piece is mounted, so that a rod-shaped component made of metal extends downward from a base end to the tip, and the rod-shaped component is cooled by means of the heat dissipation device. The ice-making process is repeated multiple times under the control of the control part, and the following steps are carried out in the ice-making process: a liquid supply step, an ice making step, an avoidance step, a deicing step, and a recovering step. The ice maker can make ice within a short period of time.
