Example Embodiment

[0014] Example 1:

[0015] Such as figure 1 As shown, the present invention includes a liquid working fluid header 12, a heat exchanger 5, a finned heat pipe 6, a depleted steam header 9 and a condensing return pipe; the condensing return pipe is composed of an inner pipe 4 and an outer pipe 3. And the two ends between the inner tube 4 and the outer tube 3 are closed to form a hollow closed sleeve. The middle of the sleeve is for air to flow to promote the condensation of the vapor working medium; the two ends of the liquid working medium header 12 are connected There is a superheater 2, and the heat exchanger 5 is located in the liquid working fluid header 12 and the superheater 2, forming a U-shaped heat exchanger assembly; the heat exchanger 5 is a split type, in the split heat exchanger 5 An electric heater 8 is installed to heat the liquid working fluid in the U-shaped heat exchanger assembly; the surface of the finned heat exchanger 6 has spiral fins 11 to facilitate heat d...

Example Embodiment

[0016] Example 2:

[0017] Such as figure 2 As shown, the structure is the same as that of Embodiment 1. The difference is that the heat exchanger 13 is an integral type. There are heat source inlet joints 14 and heat source outlet joints 15 at both ends of the integral heat exchanger 13, and the heat source inlet joints 14 and Steam or hot water is connected to the heat source outlet joint 15 as a heat source to heat the liquid working fluid in the U-shaped heat exchanger assembly.

Abstract

A gravity-style heat pipe trapezoid-combined heating radiator solves the problems of existing heat pipe radiators that the height is limited; the radiation area is small; and the heat transmission coefficient is low and the application range is narrow. The gravity-style heat pipe trapezoid-combined heating radiator comprises a liquid medium collecting pipe, a heat exchanger, a fin radiation pipe, a waste-steam collecting pipe and a condensation returning pipe. The heating radiator is characterized in that a superheater is respectively connected with two ends of the liquid medium collecting pipe and the heat exchanger is positioned in the liquid medium collecting pipe and the superheater to form a U-shaped heat-exchanger assembly; two ends of the fin radiation pipe are connected with the superheater and the fin radiation pipe is arranged in an inclined manner and the head is adjacent to the tail; the waste-steam collecting pipe is arranged on the top of the superheater and connected with the superheater; and the upper end and the lower end of the condensation returning pipe are respectively connected with the top of the superheater and the liquid medium collecting pipe and the upper end of the condensation returning pipe is communicated with the waste-steam collecting pipe. The heating radiator has the advantages that the problems that the heat-transmission medium is condensed in the radiation pipe and the height of the radiator is limited are solved; the specification of the product achieves the big, intermediate and small series; and the application range is wider; and the different requirements of people can be satisfied.

Description

technical field [0001] The invention belongs to a radiator, in particular to a gravity heat pipe trapezoidal combination heating radiator. Background technique [0002] The heat pipe is a high-efficiency heat transfer element developed in the United States in the mid-1960s, and its heat conduction capacity is hundreds of times that of ordinary metals. Gravity heat pipe is a kind of heat pipe, and its use is more and more extensive. At present, there are three structural forms of gravity heat pipe heat exchangers, single tube type, header type and separate type. The single-pipe type is composed of a single closed seamless steel pipe, the inside of which is in a vacuum state and filled with liquid heat transfer fluid. The header type is composed of multiple single-tube gravity heat pipes, and the separated type is a combination of multiple header types. But no matter what kind of structure, the lower end of the tube is a heating section, and the upper end is a heat dissipat...
