Technical Field

The invention relates to a heat exchange system suitable for a long-distance separated heat pipe, in particular to a heat exchange system of a separated heat pipe consisting of modules and units.

Background

At present, heat pipe technology is widely used in various engineering practices. Compared with the traditional integral heat pipe, the evaporator and the condenser of the separated heat pipe are connected through the ascending pipe and the descending pipe, when the heat absorption position and the heat release position are far away, the length of the heat insulation section of the heat pipe is lengthened, the long-distance heat transmission can be realized, the separated heat pipe is flexibly arranged, and the heat exchange between one fluid and various fluids can be realized while the heat exchange fluid is completely separated. The research on the separated heat pipe by domestic and foreign experts and scholars is mostly focused on the heat transfer characteristic, the medium flow characteristic and the specific engineering application of the separated heat pipe, but the research on the arrangement problem of the separated heat pipe during specific work is less, and the research on the arrangement mode suitable for the long-distance separated heat pipe is needless to say. When long-distance heat transmission is involved, the long-distance separated heat pipe can achieve the purpose of heat exchange, and in order to ensure safe, stable and efficient operation of the heat pipe, not only the element structure, the liquid filling rate, the height difference and the like of the heat pipe need to be designed, but also a reasonable heat pipe arrangement mode is needed. The whole heat exchange system is arranged in units, so that not only is the stable heat transfer of the heat pipe heat exchange system facilitated, but also the management and the maintenance of each mutually independent heat pipe unit are facilitated. Meanwhile, the heat pipe of which the heat absorbing part is firstly contacted with the hot fluid is connected with the heat pipe of which the heat releasing part is finally contacted with the cold fluid to form an independent unit, so that the working medium in each unit can fully exchange heat with the external fluid, and each independent unit is ensured to have relatively stable and efficient heat transfer efficiency. It is necessary to provide a suitable heat exchange system for the long-distance split heat pipe.

Disclosure of Invention

The invention provides a long-distance separated heat pipe heat exchange system, aiming at the problems of poor heat transfer efficiency of the current long-distance heat transfer and the like.

A long-distance separated heat pipe heat exchange system is characterized in that the heat exchange system is formed by arranging a plurality of mutually independent unit sub heat exchange modules in sequence, an air flow channel is arranged in the heat exchange system, and the arrangement direction of the air flow channel is consistent with the direction of inflow and outflow of media in the heat exchange system.

Furthermore, each unit sub-heat exchange module consists of a heat absorption sub-module, a heat release sub-module, and a steam pipe and a liquid return pipe which are connected between the heat absorption sub-module and the heat release sub-module, and the heat absorption sub-module and the heat release sub-module consist of heat pipes.

Furthermore, the arrangement sequence of the heat absorption sub-modules is the same as the flowing direction of the fluid flowing into the heat exchange system, and the arrangement sequence of the heat release sub-modules is opposite to the flowing direction of the fluid flowing out of the heat exchange system.

Furthermore, all the heat absorption sub-modules form a heat absorption module, all the heat release sub-modules form a heat release module, and the position of the heat release module is higher than the position of the heat absorption module.

(2) Meanwhile, the heat pipe of which the heat absorbing part is firstly contacted with the hot fluid is connected with the heat pipe of which the heat releasing part is finally contacted with the cold fluid to form an independent unit, so that the working medium in each unit can fully exchange heat with the external fluid, and each independent unit is ensured to have relatively stable and efficient heat transfer efficiency.

In the figure: 1. the heat absorption module comprises a heat absorption module, 2, a heat release module, 3, a steam pipe, 4, a liquid return pipe, 5, a heat absorption submodule, 6, a heat release submodule, 7, a liquid return pump and 8, an air flow channel.

Detailed Description

The present invention is described in detail below with reference to specific examples and fig. 1, and the description in this section is merely exemplary and explanatory and should not be construed as limiting the scope of the present invention in any way.

In specific implementation, the heat exchange part can be regarded as two modules according to the functional division, namely a heat absorption module 1 and a heat release module 2, wherein the heat absorption module 1 transfers heat absorbed from hot fluid to cold fluid passing through the heat release module 2. The whole heat exchange system is composed of a plurality of mutually independent units, each independent unit is composed of a heat absorption sub-module 5, a heat release sub-module 6, a steam pipe 3 and a liquid return pipe 4, and the steam pipe 3 and the liquid return pipe 4 are connected between the two sub-modules, and each unit independently completes the heat transfer process. The temperature of the hot fluid is gradually reduced when the hot fluid flows through the heat absorption module 1, and the temperature of the cold fluid is gradually increased when the cold fluid flows through the heat release module 2, so that in order to ensure that each connected heat absorption submodule 5 and heat release submodule 6 have close and stable heat transfer efficiency, the plurality of unit heat absorption submodules in the heat absorption module 1 are arranged according to the flowing direction of the hot fluid flowing into the heat exchange system, and the arranging sequence of the plurality of unit heat release submodules in the heat release module 2 is set to be opposite to the flowing direction of the cold fluid flowing out of the heat exchange system. The air flow channel 8 is arranged, the heat absorption module 1 and the heat exchange module 2 are respectively provided with a plurality of air flow channels 8, and the air flow channels 8 are internally provided with guide plates or draught fans to ensure that the air quantity of each channel is basically consistent, and the air speed is uniform and stable. When heat exchange system implementation was arranged, the heat release module 2 had certain difference in height with heat absorption module 1 under general condition, and the liquid working medium that heat release module 2 condensed out this moment can rely on self gravity to return to heat absorption module 1 along liquid return pipe 4, but if the difference in height of two modules is not enough or the distance between the two is too long, need install liquid return pump 7 in liquid return pipe 4.

The invention is suitable for the arrangement mode of the long-distance separated heat pipe, is convenient to implement and maintain, and is beneficial to ensuring the stable heat transfer efficiency of the heat pipe heat exchange system.
