Heat-recycle L-shaped heat tube of horizontal finned tube externally connected with vehicle finned tube

Abstract

The invention discloses a heat-recycle L-shaped heat tube of a horizontal finned tube externally connected with a vehicle finned tube. The L-shaped heat tube comprises an evaporation-segment heat tubebody, a balance-segment heat tube body and a cooling-segment heat tube body; the evaporation-segment heat tube body is horizontally distributed in a furnace body with a heat medium, the cooling-segment heat tube body is distributed outside the furnace body with a cold medium, and the balance-segment heat tube body is a bent tube between the evaporation-segment heat tube body and the cooling-segment heat tube body; a working medium which volatilizes when heated and condenses into liquid after cooled is arranged in the evaporation-segment heat tube body; the inner tube diameter of the evaporation-segment heat tube body is larger than that of the cooling-segment heat tube body; the balance-segment heat tube body is connected with the evaporation-segment heat tube body through a large connection and a small connector in a tube top butt joint mode. The heat-recycle L-shaped heat tube is compact in structure, the functions of horizontal tube distribution and heat exchange are achieved, thedistribution space is saved, and heat exchange is frequent and smooth.

Description

technical field [0001] The invention relates to the technical field of heat pipes, in particular to an L-shaped heat pipe in which horizontal finned tubes are externally connected to vertical finned tubes for heat recovery. Background technique [0002] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of heat pipe technology enables the radiator to obtain a satisfactory heat exchange effect, opening up a new world in the heat dissipation industry. [0003] In the existing flue gas discharge of industrial kilns, the flue gas takes away a large amount of heat, which wastes energy and pollutes the environment. A large number of heat pipes are used in flue gas waste heat recovery heat ...

AI Technical Summary

Problems solved by technology

Existing finned heat pipes are installed vertically, and horizontal installation is not allowed. The reason is that the vaporized gas of its working fluid after being heated is blocked from moving to the cooling section, and the cooled liquid cannot quickly return to the evaporation section, causing the evaporation The gas is blocked, the heat transfer effect is poor, and the heat exchange power is reduced. However, due to the limitation of the internal space of the existing equipment, the heat pipes cannot be arranged vertically in the equipment.

[0005] Based on the above situation, an L-shaped heat pipe with horizontal finned tubes externally connected to vertical finned tubes for heat recovery is now studied to solve the problem of the need to arrange horizontal heat pipes due to the space of existing equipment
