Description

The invention relates to cooling and heat sink systems, for example, to devices for cooling electronic components.

There is a method of removing heat from heat-generating electronic components in the form of radiation [1], which uses LED emitters designed to convert heat energy received from the cold junctions of the thermal module in the form of electric current into radiation energy that removes heat from the cooled device to the environment.

The purpose of the invention is improving the energy efficiency of the cooling system. This is achieved by the fact that the proposed device uses a light-emitting thermal module with a linear arrangement of p-n junctions, providing cold and light radiation. And for the subsequent complete conversion of radiation energy into electrical energy, solar panels are used.

The design of the device is presented in figure 1. The device consists of thermal module 1, in which such materials are selected as p-type and n-type semiconductor branches that the flowing current on one of the junctions 2 will generate radiation, rather than heating, as in a conventional thermal module, and in the other joint 3 thermal energy is absorbed in accordance with the Peltier effect, and solar panels 4 (consisting of a p-layer, n-layer) with mirror electrodes 5 located parallel to both sides of the thermal module, providing the conversion of radiation energy into electrical energy. Between the thermo-module 1 and the solar panels there are transparent insulators 6. The thermo-module is powered by direct current from the source 7.

As materials for the manufacture of p-type and n-type thermomodule branches, the same materials are used from which the LEDs are made, namely gallium phosphide (GaP), gallium nitride (GaN), silicon carbide (SiC), etc. For the manufacture of a solar battery gallium arsenide (Ga-As) was used. Transparent insulators are also made of gallium arsenide.

The invention relates to the field of cooling devices for microelectronic equipment. Unlike the prototype [1], there is a linear arrangement of p-n junctions that emit light in the thermal module, and two solar panels are used that are parallel to each other on two sides of the light-emitting thermal module with external mirror electrodes. The device operates as follows. When a current is passed through a light-emitting thermal module, it begins to produce cold in the electrodes at the n-p junctions and light radiation in the p-n junctions. Radiation goes in both directions. Since gallium arsenide (Ga-As) -based structures are transparent, it freely penetrates outward and, through a transparent dielectric film, reaches solar panels above and below. The solar battery is also made of gallium arsenide and is also transparent to radiation. Thus, light radiation will be repeatedly reflected between the external mirror electrodes until it is completely absorbed by the transition of the pn zone in solar cells. Multiple reflection makes it possible to completely convert radiation into electric energy or into thermal energy, which will also be transformed in the form of thermal radiation with the help of a solar battery into electrical energy.

As a result, when passing current, we get the following. The middle layer of the device will be radiation and cold. Radiation with the help of a solar battery will again turn into electricity, which can be used to re-supply the radiating thermal module, and the cold, penetrating through transparent insulators, solar panels and external mirror electrodes, will ensure the use of this design for heat removal from electronic components, which can be located both above and below the entire structure. Thus, when passing current through the thermal module, we get pure cold and light, which will be transformed into electricity, again used to produce cold. When cooling the components of electronic equipment, heat can be removed without any additional external heat sinks and coolants, converting it into electricity, which determines the energy efficiency of the developed device.

Using the presented device will improve the efficiency of heat transfer and reduce the dimensions of the heat sink, and thereby increase the intensity of the cooling system.

The use of the device in cooling systems will provide more efficient energy consumption.
