Problems solved by technology

Heating water will corrode the heating, and after the heating period is over, the heating will not be maintained by water, which will aggravate the corrosion of the heating and cause water leakage
At the same time, during the heating period and the non-heating period, the huge change in the pressure of the heating will greatly reduce the life of the heating

Embodiment 1

[0011] Refer to attached figure 1 , the present invention comprises a fully enclosed box body 1, is provided with heat exchange tube 3 in box body 1, and the two ends of heat exchange tube 3 extend out box body, is provided with liquid injection port 7 on box body 1, and liquid injection The mouth is closed by a plug, and a pressure relief hole 5 is provided at the bottom of the box body. An inverted "U"-shaped pipe 4 is installed on the pressure relief hole 5, and is closed by a plug. The expansion bag 6, the external expansion bag 6 is an expansion bag that can store liquid; the heat exchange tube is made of stainless steel corrugated tube, which has high heat exchange efficiency and corrosion resistance. An open water tank 8 embedded in the box is provided on the top of the box, and an exhaust valve 9 is provided on the box; an electric heating rod 2 can also be installed in the box 1, and the electric heating rod 2 is installed on the heat exchange tube 3 above. When in ...

Embodiment 2

[0013] Refer to attached image 3 , its basic structure is the same as that of Example 1, except that the external expansion bag 6 is replaced by a built-in expansion bag 11. Gas valve 10. When in use, inflate the expansion bag first. When heating, when the heat medium expands, it will squeeze the expansion bag, and the expansion bag will exhaust outwards, so that a slight negative pressure will be generated in the box, so as to ensure that the box will not be deformed under pressure.

Abstract

The invention relates to a micro negative pressure heat radiator which comprises a fully-closed box body and is characterized in that a heat exchange pipe is arranged in the box body, two ends of the heat exchange pipe extend out of the box body, a liquid injection hole is arranged on the box body, a pressure relieving hole is arranged in the bottom of the box body, and an external or internal expanding bag is arranged on the bottom of the box body. The invention has the advantages that: the box body of the heat radiator does not bear huge pressure of central heating water and because the expanding bag can counteract the pressure change generated by a heated heat medium in the box body of the heat radiator, the pressure born by the box body of the heat radiator is small and constant, the box body of the heat radiator is not deformed, the selection range of materials made into the box body of the heat radiator is enlarged, the box body is made of metal and can be also made of materials of glass, ceramics and the like; the box body of the heat radiator is always cured by the heat medium without being easily corroded; and the box body of the heat radiator is integral and is easy to clean, and can be made into a shape without corners so as not to easily hurt people.

Description

technical field [0001] The invention relates to a micro-negative pressure radiator, which belongs to the field of radiators. Background technique [0002] Current radiators (also called heating systems) are generally made of steel or copper-aluminum composite. Its basic structure is formed by connecting more than one group of radiators. During the heating period, all radiators must run through heating circulating hot water, that is: all radiators must be under pressure. After the heating period is over, the heating water will discharge the heating. Heating water will corrode the heating, and after the heating period is over, the heating will not be maintained by water, which will aggravate the corrosion of the heating and cause water leakage. At the same time, during the heating period and the non-heating period, the huge change in the pressure of the heating will greatly reduce the life of the heating. Contents of the invention [0003] The object of the present inven...
