Abstract

The utility model relates to an energy-saving radiator for central heating. Radiating pipes are elliptical pipes rolled by thin-walled steel pipes, and the radiating pipes are uniformly welded between the two header central covers of an upper header and a lower header with flat welding. A deflation valve is arranged on a header upper cover; the side port at one side of the header is welded with a side shell cover, and the other side is welded with a trepanning shell cover; the trepanning point of the trepanning shell cover is welded with an air (water) inlet and an air (water) outlet of the header; the header upper cover of the upper header and the header central cover of the upper header are seamed and welded together, and the header central cover of the lower header and the header lower cover of the lower header are seamed and welded together. The elliptical pipe radiator with novel shape, light self-weight and favorable radiation effect is an energy-saving radiator.

Description

Elliptic pipe radiator

This utility model is energy-saving heating radiator.

Present existing radiator mostly is cast iron type, and the template radiator also has shell and tube radiators such as pipe, square tube, triangle tube, more than laying particular stress on of having of several radiators, as cast iron type; The radiating effect that has is bad, as template radiator etc.; Its pipe of the tubular radiator that has is very little with the header interface, and hot gas (water) resistance when header flows to radiating tube is bigger, thereby causes the loss of part heat.

At above-mentioned situation, the purpose of this utility model is to provide a kind of appearance novelty, and radiating tube is arranged rationally, the energy-saving elliptical tube radiator that radiating surface is big.

The radiating tube of this utility model is the rolling oval pipe that forms of thin-wall steel tube, described radiating tube is welded between two header middle covers of upper and lower header with flat mouthful, on header, covered vent valve, end socket on the header one side side mouth and header are welded together with brazing, the perforate end socket of header uses flat mouthful of weldering to weld turnover gas (water) mouth of header again with flat mouthful of opposite side that is welded on header on the perforate end socket; The header loam cake of upper header and header middle cover, the header middle cover of lower collecting box and header lower cover are all welded together with the weldering of two sides flush joint.In order to weld oval radiating tube, in two headers, cover and open slotted eye equably, its major axis becomes 60 ° of angles between each elliptical aperture.

Described elliptical tube radiator is owing to adopt the rolling oval radiating tube that forms of thin-wall steel tube, this elliptical tube becomes the form of 60 ° of angles to arrange with its major axis again, make elliptical tube radiator appearance novelty, it is in light weight to make a fresh start, rational in infrastructure, quicken radiator not only in the horizontal direction, the side can produce heat exchange, and thermal current rises without hindrance, so do not have hot inert district, thereby improved radiating effect greatly, all weld bonds of this radiator are built-in simultaneously, make entire radiator not have the expression welding bead, give neat and artistic sense.

Below in conjunction with embodiment and accompanying drawing thereof this utility model is described in detail.

Fig. 1 is the front view of this utility model elliptical tube radiator;

Fig. 2 is a D-D face profile among this utility model elliptical tube radiator Fig. 1;

Fig. 3 is this utility model header middle cover perforate schematic layout pattern.

By elliptical tube radiator shown in Figure 1 upper and lower two headers are arranged, wherein upper header is formed by header loam cake 1 and the 2 two-sided seam welderings of header middle cover, and vent valve 8 is arranged on upper header; Lower collecting box is formed by header middle cover 2 and the 3 two-sided seam welderings of header lower cover.Oval radiating tube 4 is between two header middle covers 2 of upper and lower header, with flat mouthful of weldering welding; A upper header left side (right side) side and the second line of a couplet right side (left side) side are welded perforate end socket 5 with flat mouth weldering, and perforate is also welded turnover gas (water) mouth 7 with putting down a mouthful weldering in the middle of the identical just end socket with side seal head 6 structures of perforate end socket 5; Two side seal heads 6 of upper and lower header can be at the homonymy of two headers, also can be at the heteropleural of two headers, and perforate end socket 5 and turnover gas (water) mouthful 7 opposition sides so at end socket 6.

By shown in Figure 3, cover in the header in order to weld oval radiating tube and have oval perforate equably, each elliptical aperture is so that its major axis forms the form of 60 ° of angles arranges, modern design so not only, and increased the thermal radiation space, make its better heat-radiation effect.

Claims

1, a kind of elliptical tube radiator, it comprises upper and lower header, radiating tube, the perforate end socket, side seal head, turnover gas (water) mouth and vent valve, it is characterized in that: radiating tube is the rolling oval pipe that forms of thin-wall steel tube, this radiating tube is welded between two header middle covers of upper and lower header for flat mouthful, on header, covered vent valve, side seal head and coupling brazing on the header one side side mouth are welded together, header perforate end socket uses flat mouthful of weldering welding to be enclosed in the opposite side of header, is welded with turnover gas (water) mouth of upper and lower header again at the tapping of perforate end socket.

2, by the described elliptical tube radiator of claim 1, it is characterized in that: the header loam cake of upper header and header middle cover, the header middle cover of lower collecting box and header lower cover are all welded together with two sides seam weldering; Cover in two headers and open slotted eye equably, arranging of each elliptical aperture makes its major axis form 60 ° of angles.
