Abstract

The invention discloses a chemical heat pipe based on a reversible chemical reaction and physicochemical heat effect. The chemical heat pipe comprises a synthesis reaction section and a decompositionreaction section, a vertical lifting pipe penetrating through the synthesis reaction section and the decomposition reaction section is arranged in the heat pipe, a liquid distributor, a packing chamber and a packing supporting plate are arranged on the synthesis reaction section from top to bottom, and inner fins and outer fins are arranged in the synthesis reaction section and the decomposition reaction section. According to the chemical heat pipe and a heat transfer method, a working medium can be ammonium carbamate, carbon dioxide and ammonia gas, a remarkable physicochemical heat effect during the synthesis / decomposing reaction process of the ammonium carbamate is used for realizing the heat transfer, unit heat capacity is remarkably increased, and heat transfer ability is not limitedby the heat transfer limit such as the traditional heat pipe sound velocity limit, capillary limit, carrying limit, boiling limit and the like.

Description

technical field [0001] The invention relates to a heat transfer element, in particular to a chemical heat pipe and a heat transfer method based on a reversible chemical reaction physicochemical heat effect. Background technique [0002] Evaporation-condensing traditional heat pipes are heat transfer elements that rely on the phase change of their internal working liquid to achieve heat transfer. They have many excellent characteristics such as high heat transfer coefficient, small heat transfer temperature difference, and no need for external power. However, the heat transfer capability of heat pipes is also limited by heat transfer limits such as sound velocity limit, capillary limit, carryover limit, boiling limit, etc., and these heat transfer limits are closely related to phase change heat. [0003] At present, the traditional heat pipe is an evaporation-condensation heat pipe, which uses the physical process of the phase change of the working fluid to achieve heat trans...
