Abstract

The utility model discloses a central heating radiator includes a plurality of heat transfer units, its characterized in that: the heat transfer unit comprises interior sleeve pipe and outer tube, interior sleeve pipe and outer tube are two -layer and revolve to opposite spiral grooved tube, interior sleeve pipe and outer tube weld respectively on first line of a couplet pipe and second line of a couplet pipe, the cavity and the last second line of a couplet pipe intercommunication that form between the two. The heat transfer unit that adopts the inside and outside sleeve pipe of reverse double helix to form has increased heat transfer area for heat transfer speed.

Description

Radiator

Technical field

This utility model relates to heating plant field, is specially a kind of radiator.

Background technology

Conventional radiator, whether " 60 formula " or " four-column type " are all contain hot water in device, outwardly dispel the heat by it, and the common drawback that they exist is that in device, heating agent motion is advection (laminar flow) motion, and area of dissipation is little, and heat exchange efficiency is low.

Utility model content

This utility model is for above weak point, it is provided that a kind of radiator, adopts the heat exchange unit of reverse double-helix internal and external casing composition, increases heat exchange area, accelerate heat transfer rate.

This utility model solves its technical problem and be the technical scheme is that a kind of radiator, include some heat exchange units, described heat exchange unit is made up of inner sleeve and trocar sheath, described inner sleeve and trocar sheath are the spiral grooved tube that two-layer is oppositely oriented, described inner sleeve and trocar sheath are respectively welded in upper union and lower union, and the cavity formed therebetween connects with upper and lower union.

Offering porose in described upper union and lower union, the cavity formed between described hole with two-layer inner sleeve connects.

This utility model changes the structure of traditional heat sinks, his heat exchange unit is made up of the deep spiral barrel in the oppositely oriented direction of inside and outside two-layer, heating agent flows downward in the form of mutual switching direction and flow regime by internal and external screw barrel in interlayer, fluid is made almost to be completely in turbulence state, Reynolds number is made to be greatly improved, therefore make the coefficient of heat transfer be greatly improved, simultaneously the inner surface of the outer surface of outer tube and interior pipe is all directly and air streams contact, its radiating surface is made to be greatly increased, and internal and external casing is screw-like, therefore increase area of dissipation, by the air of heat exchange fully from pipe with pore in motion from bottom to top, thus having reached the purpose of high efficient heat exchanging.

Accompanying drawing explanation

It it is structural representation of the present utility model shown in Fig. 1;

Fig. 2 show in Fig. 1 A-A directional profile figure.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in detail:

It as shown is a specific embodiment of the present utility model, a kind of radiator, include some heat exchange units 3, described heat exchange unit 3 is made up of inner sleeve 7 and trocar sheath 6, described inner sleeve 7 and trocar sheath 6 are the spiral grooved tube that two-layer is oppositely oriented, described inner sleeve 7 and trocar sheath 6 are respectively welded in upper union 2 and lower union 4, and the cavity formed therebetween connects with upper and lower union. Offering porose in described upper union 2 and lower union 4, the cavity formed between described hole with two-layer inner sleeve 4 connects.

When using this heating exchanger, in the cavity that inner sleeve 7 and trocar sheath 6 are formed, heating agent is injected by the water inlet 1 of upper union 2, heating agent can be oil, it is also possible to be water, after heating medium for heating, flow downward in the form of mutual switching direction and flow regime by internal and external screw barrel in interlayer, make fluid almost be completely in turbulence state, outwards dispel the heat, after heat release, heating agent converges to lower union and returns water return pipeline, completes thermal cycle. Outside trocar sheath directly and extraneous contact, the cavity formed inside inner sleeve also directly and extraneous contact, forms the good convection current of air, and heat transfer effect is better.

Certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above, the change made in essential scope of the present utility model of those skilled in the art, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.

Claims

1. a radiator, include some heat exchange units, it is characterized in that: described heat exchange unit is made up of inner sleeve and trocar sheath, described inner sleeve and trocar sheath are the spiral grooved tube that two-layer is oppositely oriented, described inner sleeve and trocar sheath are respectively welded in upper union and lower union, and the cavity formed therebetween connects with upper and lower union.

2. radiator according to claim 1, it is characterised in that: described upper union and offer porose in lower union, the cavity formed between described hole with two-layer inner sleeve connects.
