Composite radiator

Abstract

A composite radiator is characterized by comprising a water supply pipe and radiating plates. The composite radiator is formed by means of tightly holding the water supply pipe with semi-circular pipe grooves of an inner radiating plate and an outer radiating plate in a fit manner or by means of inserting the water supply pipe into an open circular pipe groove in the radiating plates. For the radiating plates, besides the outer radiating plate or a radiating panel radiates directly, the inner radiating plate or radiating rib plates at the upper edge and the lower edge of the round pipe groove assist in radiating. A convection radiating air flow passage is reserved between the inner radiating plate and the outer radiating plate or between the radiating rib plates and the radiating panel. The outer surfaces of the radiating plates are sprayed with high-radiant-emittance coating or paint; the water supply pipe is a copper pipe, aluminum pipe or a stainless steel bellow; an thermal-conductive adhesive is coated between the water supply pipe and the semicircular pipe groove of each radiating plate; the composite radiator can be mounted at the position of a skirting and is fixed at the foot of a wall by screws or iron nails. The composite radiator is easy to produce, convenient to mount and assemble, high in radiating capability and cheap, and can be used with a heat pump for heating.

Description

technical field [0001] The invention belongs to the field of heating, and relates to an air convection radiator using hot water as heat-carrying fluid. Background technique [0002] At present, there are three types of heating radiators on the market, the combination of hot water channels and fins: one-piece, nested and welded. One-piece radiators include cast iron tube radiators, cast or drawn aluminum tube fin radiators , The nested type has a copper-aluminum composite radiator, and the welded type has a steel plate and column radiator. For aluminum and steel plate welded radiators, once the water channel is corroded by chloride ions in the water and leaks, the entire radiator needs to be replaced. The nested copper-aluminum composite radiator has good heat dissipation performance, but the manufacturing process is complicated. First, the copper tube should be inserted into the aluminum tube sleeve, and then the copper tube and the aluminum tube should be in close contact ...

AI Technical Summary

Problems solved by technology

The nested copper-aluminum composite radiator has good heat dissipation performance, but the manufacturing process is complicated. First, the copper tube should be inserted into the aluminum tube sleeve, and then the copper tube and the aluminum tube should be in close contact with the tube expansion method. The water pipe is welded with the upper and lower water pipes of the radiator, and then the leak test is performed to check the quality of the welded joints

In order to overcome the troubles of making traditional heating radiators, the utility model "A Radiator" (201020062430.3) proposes a radiator in which a water pipe and a single cooling fin are integrated. The advantage is that it can be drawn into shape at one time. It is placed on the corner of the wall and is expected to replace the traditional radiator and baseboard. However, the biggest disadvantage of this radiator is that it only dissipates heat from one side, and the heat dissipation capacity is poor. It requires a higher temperature of heating water. If you use a safe 50-55 ℃ heating hot water, its heat dissipation capacity cannot meet the heating needs; in addition, the water channel of the integrated aluminum radiator is in danger of being corroded
