Abstract
The utility model relates to a heat exchanging tube which comprises a tube body, wherein a spiral dummy club is arranged on the inner wall of the tube body, a spiral groove is arranged on the outer wall of the tube and jagged fins which are arranged on the outer wall of the tube body are axially arranged along the tube body at intervals. Saw teeth are machined on the fins in the method of mechanical machining on the basis of the spiral grooved tube, so the circumference of the outer margin of each of the fins is increased and the outer surface area of the tube body is increased. Moreover, each of the sharp saw teeth has the capability of dripping liquor condensate. The thickness of a condensate film can be thinned so that the condense heat exchange is intensified. Simultaneously, the wetted perimeter of a flow channel of the liquor condensate is in periodic variation due to the fact that the saw teeth are machined on the basis of the spiral grooved tube. The lateral surface of each of the fins has a definite degree of roughness. Therefore, the flowing condition of the liquor condensate is disturbed to generate local vortexes. Moreover, bulges of the spiral grooves are arranged in the tube so that the heat exchange coefficient is increased. The utility model has the advantages of reasonable structure and high heat exchanging efficiency.
Description
Technical field
The utility model relates to a kind of heat-exchange tube, the heat-exchange tube on particularly a kind of evaporimeter or the condenser.
Background technology
The heat-exchange tube that common evaporimeter or condenser are used, its body has helical fin outward, and the advantage of this structure is to increase heat transfer area, improves the heat exchange effect; But remain smooth in its pipe, the liquid in pipe type of flow shows as laminar flow, and the heat exchange effect during owing to laminar flow is poor, so make the user not too satisfied.
The utility model content
The purpose of this utility model is to provide a kind of simple and reasonable, heat-exchange tube that heat exchanger effectiveness is high, to overcome weak point of the prior art.
A kind of heat-exchange tube by this purpose design comprises body, and its architectural feature is that inboard wall of tube body is provided with the spirality boss, and the pipe outer wall is provided with spiral groove.
Above-mentioned tube wall is provided with jagged fin, and spiral groove is through fin.
Above-mentioned fin is arranged along the body axially spaced-apart.
The spirality direction of above-mentioned groove is consistent with the spirality direction of boss.
Above-mentioned boss is corresponding with the partition groove between every group of fin, and per three to eight of fin is one group.
Above-mentioned partition groove is than the low 0.1～0.5mm of the groove location in every group of fin.
Above-mentioned groove cross section is triangle or polygonized structure.
The utility model is provided with the spirality boss in the heat-exchange tube inboard wall of tube body of band helical fin, thereby changes the type of flow of tube fluid: the turbulence intensity when the increase tube fluid flows, destroyed heat transfer boundary layer, and intraductal heat transfer is strengthened.Strengthen its exchange rate, improve heat exchange effect.
The utility model method with machining on the basis of spiral grooved tube is processed sawtooth on fin, the outer rim girth of this fin increases, increased the external surface area of body, and this sharp-pointed sawtooth has the drippage ability of condensate liquid, but the thickness of attenuate condensate film is strengthened condensing heat-exchange; Owing to be the sawtooth of processing on the basis of spiral grooved tube, the wetted perimeter of condensate liquid runner is cyclically-varying simultaneously, and there is certain roughness the fin side, disturbed the flow condition of condensate liquid, produce local eddy currents, and the helicla flute projection is arranged in pipe, the coefficient of heat transfer is improved.
The utility model is simple and reasonable, the heat exchanger effectiveness height.
