Abstract
The utility model relates to a heat-transfer pipe, which adopts the structure of increased heat-transfer surfaces both outside and inside pipe fittings. The utility model is characterized in that the outer wall of a heat-transfer guide pipe is provided with longitudinal tooth-shaped heat-transfer strips; longitudinal grid-type or punched pipe segments, or punched sectorial strip-shaped or punched irregular sectorial strips are arranged in the heat-transfer guide pipe; the irregular sectorial strips are composed of elliptical strips at the upper end and sectorial strips at the lower end. The utility model has the advantages that the unit area heating quantity of the heat-transfer pipe is enhanced, the heat is rapidly transferred, heat efficiency is enhanced, and the energy is saved.
Description
The utility model relates to and not only adopts the heat-transfer pipe that increases the thermal conductive surface structure in the pipe fitting outside but also in inside.
At present, usually run into the device of heat exchange in industrial production and people's daily life, normally used heat pipe is a primary element in heat exchange, and heat pipe is generally steel pipe, copper pipe or aluminum pipe.The patent No. is ZL85107311, and the day for announcing is the Chinese patent on June 15th, 88, discloses a kind of heat-transfer pipe.It is characterized in that: on the inner wall surface of conducting tube, have the helical curve of a row at least along heat-transfer tube, the projection of arranging with the spacing of rule, the height of projection is in 0.45mm to 0.6mm scope, projection along the pitch of helical curve in 3.5mm to 5mm scope, projection pitch in the axial direction is in 5mm to 9mm scope, and this heat-transfer pipe has increased very big heat transfer area.If the inside and outside very big needs of the hot temperature difference heat exchange at short notice of heat-transfer pipe, obvious this heat exchange area does not still satisfy needs.
The purpose of this utility model provides at the inside and outside heat-transfer pipe that increases heat-conducting area simultaneously of heat transfer tube.
The technical solution of the utility model is finished like this.
Heat-transfer pipe is characterized in that: the outer wall of heat transfer tube has vertical profile of tooth heat conduction bar; In the heat transfer tube vertical grating type or pipeline section with holes or fan bar shaped with holes or different fan-shaped with holes; Form by the ellipse of upper end and fan-shaped of lower end for different fan-shaped.
The utility model has the advantages that, improved the unit are received heat of heat-transfer pipe and passed out heat rapidly, improve the thermal efficiency, energy savings.This heat-transfer pipe is machinery production continuously, at the bottom of the cost.
