Abstract

The utility model relates to a radiating fin. The bottom of the radiating fin is provided with a medium cavity, and a plurality of vertically arranged heat conduction/radiation devices which penetrate the medium cavity are arranged on the medium cavity; the heat conduction/radiation device and the medium cavity are pumped to form vacuums; highly effective thermal conduction medium is filled in the medium cavity; a heat source pipe which passes through the medium cavity is arranged in the medium cavity. For the radiating fin with the structure, because the heat source only passes in and out through the heat source pipe without requiring circulating in a radiating cavity, the energy source is saved; because the highly effective conduction medium is used, the thermal conduction speed is accelerated, and the purpose of rapid temperature rise is obtained.

Description

A kind of fin

The utility model relates to hot conduction field, and what relate to specifically is a kind of fin that can reach the heat radiation purpose by various thermals source.

The general fin of China has two kinds of hot-water heating or hot air heatings at present, and mostly its working method is to flow in the chamber within it by hot water or steam, receives heat by circulation in the cavity, and the heat of fluid comes out, to reach the purpose of heating.This class fin must circulate at inner chamber by hot fluid, and need the installation loop pipe to form heating system, the deficiency that exists is: the heat-conducting efficiency of heat transfer mediums such as hot water, steam is very low, thereby cause energy resource consumption big, the wasting of resources and in fin, easily cause problems such as corrosion, installation and maintenance load in the fin be big.

The purpose of this utility model is in order to solve the problem that above-mentioned prior art exists, a kind of thermal source and heat-conducting medium partial installation to be provided, and thermal source does not need to circulate in heat-dissipating cavity, and heat conduction velocity is fast, and the few fin of consumes energy.

For achieving the goal, the utility model is to realize by such technical solution: a kind of fin, this fin bottom is provided with dielectric cavity, dielectric cavity and is provided with vertical arrangement and leads heat abstractor with dielectric cavity connects, dielectric cavity and the heat pipe working cavity chamber of leading a heat abstractor internal communication of formation and isolating fully with the external world, the indoor vacuum pumping of heat pipe working cavity.Lead heat abstractor and be provided with outer radiating fin outward; Be filled with efficient heat-conduction medium in the dielectric cavity, be provided with the heat source tube of passing dielectric cavity in the dielectric cavity.The thermal source of said heat source tube can be steam source, electric heat source or heat source of hot water.

Feature of the present utility model is that also outer radiating fin is the telescoping structure of up/down perforation and is placed in dielectric cavity and the periphery of leading heat abstractor.

The utility model compared with the prior art because thermal source and heat-conducting medium split, heat source tube independently is provided with, thermal source is only by the heat source tube turnover, need be through in fin, circulating, thus made things convenient for installation and keeped in repair; Owing to adopted heat-conduction medium efficiently, heat transfer system starts fast, the temperature height, the transmission heat is big, thereby quickened the exchange velocity of cold and heat air, solved the large-scale heat supply stove of need of existing heating equipment existence and the shortcoming of a large amount of recirculated waters, had simple in structure, improve advantages such as the thermal efficiency, having reached the heat radiation and heating is good, the purpose of saving the energy of being rapidly heated.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is the structural representation of fin;

Fig. 2 is that the A-A of fin is to cutaway view (part).

In the bottom of fin 1 dielectric cavity 3 is arranged, dielectric cavity 3 is an annular seal space, dielectric cavity 3 be provided with many vertically arrange lead radiating tube 4, lead radiating tube 4 and communicate with dielectric cavity 3, lead radiating tube 4 tops and be connected with transverse tube with dielectric cavity 3 parallel placements, transverse tube is an annular seal space.Dielectric cavity 3, lead radiating tube 4 and transverse tube vacuum pumping, charge into efficient heat-conduction medium in the dielectric cavity; Heat source tube 2 is passed dielectric cavity 3, and the thermal source mouth of heat source tube 2 exposes, and the thermal source mouth can connect hot water, steam or other hot-fluids, perhaps makes heat source tube 2 intensification heat conduction by the thermocouple heating.Dielectric cavity 3, lead that radiating tube 4 is outer to be with outer radiating fin 5, outer radiating fin 5 can be by being pressed into being welded on dielectric cavity 3 both sides by several the trapezoidal outer fin of forming and making of correspondence, and outer radiating fin is the telescoping structure of up/down perforation.

During use, after passing through the hot-fluid more than 50 ℃ in the heat source tube 2, owing to be filled with efficient heat-conduction medium in the dielectric cavity 3, making medium gasification and rapid rising enter leads in the radiating tube 4, meet cold generation heat exchange and emit heat, heat transmits through leading radiating tube 4 rapidly, because the periphery is with outer fin wing 5, make from leading heat that radiating tube 4 bottoms give out by outer radiating fin 5 encirclements, impel heat in the bottom unlikely scatter and disappear and continue to carry out cold and hot air exchange to top, heat exchange by this structure, cold and hot air exchanges convection current rapidly in the room, thereby reached the good purpose of the whole heating effect in room,, thereby saved the energy again because hot-fluid only passes through heat source tube 2 turnover.
