METHOD OF TRANSMITTING HEAT AND HEAT TRANSFERRING DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC F28D15/04 

FIELD: heat exchange.

SUBSTANCE: invention relates to the devices for transferring heat from a heated surface to a cold one according to the principle of a heat tube, that is, due to the evaporation and/or partial boiling of the working fluid in the pipe, in the zone of contact with the heater, and condensation of vapors in the zone of contact with the refrigerator, with the circulation of the working fluid inside the heat pipe, and can be used in electronics for cooling microprocessors, chipsets, high-power LED lamps, in the chemical industry for cooling and heating microreactors, for utilizing heat of reactions, in household machines (in refrigerators, dishwashers, water heaters and other devices), for cooling welding machines, in solar energy to increase the efficiency of water heating in solar collectors, as well as for other purposes. Method of heat transfer from the heater to the refrigerator using the principle of a gravitational heat tube, which consists in the fact that the heat flux is transferred from the heater to the refrigerator using a tube closed into a ring consisting of one or several turns partially filled with heat-transfer fluid, during heating of which the formation of the two-phase system, moving through the tube in the slug mode is carried out. Heat is supplied to the tube by the heater and heat is withdrawn from the tube by the cooler asymmetrically so as to create a continuous upward movement of the heated coolant in one of the elbows of each of the turns of the tube, while in the other elbow of the turns of the ring the tubes create a continuous downward movement of the heated coolant. Heat transfer device for carrying out the method is also presented. According to the invention, the asymmetrical supply of heat to the tube and the removal of heat from it are realized by the fact that the heater and refrigerator have an asymmetrical shape, with one part of the surfaces of the heater and refrigerator placed horizontally and the other part placed vertically. In addition, in the heat transfer device, additional starting heating elements are installed on one or several of the ascending tubes, and additional starting cooling elements are installed on one or several of the descending elbows of the tube.

EFFECT: invention allows to increase the transmitted thermal power, to increase the stability and efficiency of the device due to the guaranteed directional circulation of the coolant through the channels of the heat pipe, and also allows to facilitate the controllability of its starting.
