Abstract

A column-shaped heat radiator with fins is made up through making composite bimetal pipe with internal copper pipe and external aluminium pipe, and vertically welding 4 or more groups of fins to the external surface of said composite pipe. Four or more said finned pipes are longitudinally arranged. Its top end is connected to water inlet pipe and its bottom end is connected to water outlet pipe. Its advantages are small size, high heat exchange speed, great radiating area and high radiating efficiency.

Description

Cylindrical Cu-Al heat radiator with fins

Skill this area

The present invention relates to a kind of heating equipment, specifically is a kind of cylindrical Cu-Al heat radiator with fins.

Background technology

The radiator kind of using as heating equipment at present is a lot, difference according to the heating medium, it is warm etc. to be divided into hot-water heating, steam heating, electricity, and the employed material of warmer equipment also has differentiation, and modal have cast iron steam to warm up radiator, fin water tube steam heating radiator and ratio-frequency welding panel radiator.Though the warm radiator of all kinds of fin tube type steam that prior art is produced has certain advantage than warm radiator of cast iron steam and ratio-frequency welding radiator on weight, volume, production cost, but exist complex manufacturing, foot phenomenon not such as consumption of materials is big, radiating efficiency is low, its various finned tubular radiator all is that sheet metal perforation back string is formed finned tube on common water pipe, between water pipe and the fin just point contact, institute's radiating efficiency is far away from cast-iron radiator and high frequency panel radiator.In addition, the material that is adopted is generally cast iron or steel plate, and its heat transfer coefficient is lower, and rate of heat exchange is slow, and along with the thickening of oxidation on metal surface layer in the use, radiating efficiency also decreases simultaneously.

Summary of the invention

The defective that purpose of the present invention exists at prior art and provide a kind of with copper pipe and aluminum pipe become multiple tube, through the cylindrical Cu-Al heat radiator with fins of machining formation, have the performance that volume is little, rate of heat exchange is fast, area of dissipation is big, radiating efficiency is high, easy to install.

The objective of the invention is to realize by following technical scheme: a kind of cylindrical Cu-Al heat radiator with fins, constitute by water inlet pipe and outlet pipe, its A. is processed into composite bimetal pipe with interior copper pipe and outer aluminum pipe earlier; B. again on the described copper aluminum composite pipes outside vertical welding be connected to that symmetry is the fin that the spider shape distributes more than four groups or four groups, be adjacent on two groups of symmetry fins of one group of symmetry fin both sides, positive front and back vertical then before and after radiation panel; C. the described copper aluminum composite pipes of band fin more than four or four is vertically arranged, pipe end and described water inlet pipe are laterally connected on its described copper aluminum composite pipes, following pipe end and described outlet pipe are laterally connected, described water inlet pipe one end is communicated with the heating thermal source, the other end is provided with vent valve, described outlet pipe one end is connected with circulating water pipe, and the other end is provided with plug.

The present invention adopts technique scheme, have reasonable in design, simple in structure, volume is little, in light weight, be easy to processing, characteristics such as the heat transfer rate is fast, easy to install, be worth of widely use.

The specific embodiment

Below in conjunction with drawings and Examples in detail the present invention is described in detail.

Shown in Fig. 1-5, a kind of cylindrical Cu-Al heat radiator with fins is made of water inlet pipe 1 and outlet pipe 2, and its A. is processed into composite bimetal pipe 3 with interior copper pipe 4 with outer aluminum pipe 5 earlier; B. again on copper aluminum composite pipes 3 outsides vertical welding be connected to more than four groups or four groups symmetry and be the fin 6 that the spider shape distributes, radiation panel 7-1 before and after two groups of symmetry fin 6-2 that are adjacent to one group of symmetry fin 6-1 both sides, positive front and back go up and vertically follow, 7-2, then the copper aluminum composite pipes 3 of band fin 6 more than four or four is vertically arranged, pipe end and water inlet pipe 1 are laterally connected on its copper aluminum composite pipes 3, following pipe end and outlet pipe 2 are laterally connected, water inlet pipe 1 one ends are communicated with the heating thermal source, the other end is provided with vent valve 8, outlet pipe 2 one ends are connected with circulating water pipe, and the other end is provided with plug 9.Among the embodiment 1, it is vertically arranged by four copper aluminum composite pipes 3 as shown in Figure 1.Among the embodiment 2, it is vertically arranged by six roots of sensation copper aluminum composite pipes 3 as shown in Figure 2.

In the above-mentioned enforcement side, interior copper pipe 4 external diameter φ are 22-0.1mm, and pipe thickness is 0.1mm, and outer aluminum pipe 5 internal diameters are 22+0.1mm, and pipe thickness is 0.1mm, and copper aluminum composite pipes 3 length are 500-600mm; Front and back radiation panel 7-1,7-2 highly are 400-500mm at a distance of 58-60mm, and width is 60-62mm, and plate thickness is 0.8-1.0mm, and material is an aluminium sheet; Fin thickness is 0.6-0.8mm, highly is 400-500mm, and the width of three groups of symmetry fin 6-3 of positive front and back one group of symmetry fin 6-1 and both sides is 2-4mm less than radiation panel 7-1,7-2 width, and the material of fin 6 is an aluminium sheet.

During use, after water inlet pipe 1 one ends and the connection of heating thermal source, its hot water or steam are flowed into respectively in the copper aluminum composite pipes 3 by water inlet pipe, go up the fin of installing 6 by copper aluminum composite pipes 3 and pipe thereof, carry out exchange heat, and front and back radiation panel 7-1 by being connected with fin 6,7-2 carries out heat radiation, and front and back radiation panel 7-1, unequal and the panel 7-1 of multiple tube 3 upper panel width between 7-2 width and two plates, the height of 7-2 is short in the length of multiple tube 3, between fin 6, form cross-ventilation, cold air is entered by the lower curtate space, hot-air after the heat exchange is emitted by upper space, makes it heat and is fully exchanged and discharge, and reaches best radiating effect.Thereby radiator of the present invention is a kind of desirable heating equipment.
