Abstract
The utility model relates to a heat exchanger part, in particular to an internal and external spiral pipe which is composed an internal spiral structure and an external spiral structure and has a large inner surface area and a large outer surface area. The spiral structures enable a heat exchange body to rotate so as to more sufficiently exchange heat, and thereby the heat exchange efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of heat exchanger accessory, specifically is meant a kind of internal and external screw pipe.
Background technology
Heat exchanger is used very wide very generally aspect heat exchange now.The heat-exchange tube of current heat exchanger mostly is straight-through light pipe or riffled tube, and when material one timing, the efficient of heat exchange is directly proportional with the heat exchange area of heat-exchange tube.The efficient that therefore will improve heat exchange just must increase heat exchange area.
Summary of the invention
The technical problem that the utility model need solve: being exactly increases heat exchange area under the constant situation of caliber size.
The technical scheme that the utility model adopted: the utility model comprises by an inside spin (1) and an external spiral (2).
The beneficial effects of the utility model: its surfaces externally and internally of being made up of inside spin structure and external spiral structure is long-pending very big, and because of helical structure makes the rotation of heat exchange body that heat exchange is more abundant, so the efficient of its heat exchange is greatly improved.
Description of drawings
(1) is inside spin in the schematic diagram of the present utility model, and (2) are external spiral.
The specific embodiment
Referring to (1) in the schematic diagram and (2), the utility model is made up of with (2) (1) of a body.Can adopt machined or other method to realize.
Claims (1)
1. an internal and external screw pipe comprises by inside spin structure and external spiral structure and forming, and it is characterized in that: the combination of inside spin structure (1) and external spiral structure (2).
