Problems solved by technology

Moreover, the temperature of the base thermal equilibrium point of the cooling device is relatively high during operation, resulting in low production capacity of the equipment, and it is impossible to produce more high-quality rapid solidification material products on the basis of the existing solidification technology
So far, the inventor has not found relevant reports on applying the heat pipe technology to the rapid solidification technology

Embodiment 1

[0021] Example one see figure 1 The structure shown. The integrated heat pipe is used to produce a single piece of block-shaped quick-setting metal cold mold. The closed cavity 2 of the cylindrical shell 1 of the heat pipe is evacuated and filled with heat transfer medium. The enclosed cavity 2 is provided with 24 sets of thermal conductivity. The solid copper heat container 3 with large heat capacity is used as the heat carrier. Each group of heat container 3 shares the heat transfer medium in the same enclosed cavity 2. The heat container 3 is the condensing end, and the shell 1 is provided with heat absorption through the shell 1 The cavity 5 serves as the heat-absorbing end. The surface of the heat-absorbing cavity 5 of the heat pipe shell 1 contacts the heat source to absorb heat, and the heat is transferred to the same heat-conducting medium in the same enclosed cavity 2 through the heat-absorbing end wall of the cavity 5 to make the heat-conducting medium Absorption or vap...

Embodiment 2

[0022] Example two, see figure 2 As shown in the structure, the integrated heat pipe can be used to make cold molds for the continuous production of fast-setting metal wires. The shell 1 that wraps the closed cavity 2 can be processed into any three-dimensional shape, such as a cylinder, a cube, a cuboid, a sphere, an ellipsoid, or others. polyhedron. The enclosed cavity 2 of the casing 1 is evacuated and filled with a heat transfer medium. The enclosed cavity 2 is provided with 60 groups of fluid channels 4 as heat carriers, and the cooling fluid is used to transfer heat. The fluid channels 4 share the same enclosed cavity 2 and share the heat transfer medium in the same enclosed cavity 2. The fluid channel 4 is the condensation end, and the shell 1 is provided with a heat absorption cavity 5 penetrating through the shell 1 as the heat absorption end, and the heat pipe The surface of the heat absorption cavity 5 of the shell 1 contacts the heat source to absorb heat, and the hea...

Abstract

An integrated heat tube and heat exchange method includes vacuum sealed cavity and a shell filled with heat transfer medium, in which, in the sealed cavity there are one or more than one heat carriers, each shares the medium in the cavity, the heat carries is the condensed end and the shell or a part are the heat-absorbing end which surface contacts heat source and absorbs heat to transfer heat to a same medium in the same sealed cavity via the wall face, so the said medium absorbs or evaporizes the absorbed heat and the heat carrier will contain or transfer heat absorbed by the medium which will recover the original state to circulate heat exchange after radiation and condensation.

Description

Technical field [0001] The invention relates to an integrated heat pipe and a heat exchange method thereof, belonging to the technical field of heat exchange. Background technique [0002] A conventional heat pipe is a tube that closes both ends of a pipe, and the inner wall of the pipe is filled with a small amount of heat transfer medium after special treatment, and uses the heat transfer medium to undergo phase change or the superconductivity of some inorganic media to absorb heat, release heat and transfer heat. part. When the heat pipe works, one end absorbs heat and the other end releases heat. In order to overcome the influence of gravity and centrifugal force, a tube core structure can be arranged in the heat pipe, and the capillary force is used to guide the heat transfer medium to flow in a directional direction to the heat absorption end. The heat pipe heat exchanger is composed of a number of the above-mentioned heat pipe elements, with one en...
