Low-temperature heating radiating pipe and radiator

Abstract

The invention provides a low-temperature heating radiating pipe and a radiator. The low-temperature heating radiating pipe comprises an annular sleeve, wherein the annular sleeve comprises an inner pipe and an outer pipe, and an annular gap between the inner pipe and the outer pipe forms a water passing channel of heating medium water; and a hollow cavity with openings in the top and the bottom isformed in the annular sleeve in the radial direction, so that air can enter the annular sleeve from the bottom of the hollow cavity and is exhausted from the top of the hollow cavity after absorbingheat so as to achieve the chimney effect of air flowing. The annular gap is formed in the annular sleeve, and the heating medium water can dissipate heat outwards through the inner pipe and the outerpipe in the annular sleeve at the same time, so that the heat exchange area of the radiating pipe is effectively increased. The hollow cavity is formed in the annular sleeve in the radial direction, so that an air convection channel is effectively formed, the chimney effect of air which flows in the annular sleeve is enhanced, air can fully absorb heat in heating medium water, and the low-temperature heating radiating pipe is more suitable for being used in a heating environment with low-temperature heating medium water as a heat transfer medium.

Description

technical field [0001] The invention relates to the field of radiators, in particular to a low-temperature heating radiating pipe and a radiator. Background technique [0002] As the terminal equipment of heating, the radiator is generally the central heating in the city, the self-built boiler room in the community, the wall-hung boiler in the home, etc., and the heat is released through heat conduction, radiation, and convection to increase the temperature of the room. [0003] At present, the known heating radiators are all columnar structures, and water passages for the circulation of heating medium water are arranged in the tube column, and multiple tube columns are connected between the upper piece head and the piece head of the heat sink, forming an overall heat dissipation system. device structure. By compactly arranging the pipe column on the heat sink, the overall size is reduced, and the flow rate of the heat medium water inside the heat sink is improved. [0004...

Problems solved by technology

[0004] However, in the prior art, the convective heat transfer of the air between the pipe strings is not fully considered, and it cannot meet the increasingly high heating demand only from the perspective of heat radiation and dissipation in the radiator.
