Abstract
The utility model discloses a heat transfer enhancement streaming belt, comprising a belt body, wherein a plurality of strip holes are distributed in the belt body; a supporting strip is formed between adjacent strip holes; the directions of the support strips are identical with the directions of the strip holes; the directions of the strip holes are vertical to the direction of the belt body; and a spiral tie with the strip holes is formed by twisting the belt body spirally and is in clearance fit with a heat exchange pipe. The heat transfer enhancement streaming belt has the beneficial effects that the structure is simple, the processing is easy, the heat transfer enhancement effect is good, the resistance loss is small, and the mounting and replacement are convenient; compared with the existing heat exchanger, the heat transfer enhancement streaming belt has the advantages that the heat exchange amount can be improved under the condition of not increasing the heat transfer area when the structure is mounted, and the modification cost can be reduced; compared with a heat exchanger with a new design, the heat transfer enhancement streaming belt has the advantages that the heat transfer area and size of the heat exchanger can be reduced under a certain heat exchange load when the structure is mounted, and the manufacturing cost is reduced; and in an occasion with dirt, when the belt body is pulled out for exchange, the function of removing the dirt can be realized.
Description
Technical field
The utility model relates to a kind of son that streams of augmentation of heat transfer, specifically a kind of strip that reverses in the shape of a spiral.
Background technology
Spiral band be a kind of strengthen intraductal heat transfer common stream element, the solid metal strip of basic structure for reversing in the shape of a spiral, its cardinal principle of strengthening intraductal heat transfer is by the introducing eddy flow, increases flow velocity and the flow process of fluid, thereby causes the raising of the coefficient of heat transfer.The conventional helical tie has also caused higher fluid resistance loss (pressure drop) when improving heat transfer coefficient.The strengthening mechanism of conventional helical tie, all there is obvious limitation in the raising that its strengthening effect, application scenario and unit resistance loss increase the heat transfer coefficient that brings.
Summary of the invention
The utility model is narrow for present spiral band range of application, unit resistance increases and the unconspicuous problem of the raising of heat transfer coefficient, has proposed the son that streams of the wide augmentation of heat transfer of a kind of heat transfer coefficient, range of application.
Augmentation of heat transfer described in the utility model stream son, comprise belt body, it is characterized in that: some bar holes that distribute on the described belt body form between the adjacent bar hole with bar hole and move towards consistent support bar; The trend of described bar hole is vertical with the trend of belt body; Described belt body screw twisted forms the spiral band with bar hole, and with the heat exchanger tube matched in clearance.
Described bar hole is evenly distributed along belt body.
Described bar hole is rectangle.
The pitch of the spiral band that the width of the width of described belt body, the bar hole of described belt body, the width of described support bar, described belt body form and installation length and the mounting means of described belt body are all adjusted according to the heat exchanger tube that is inserted into.
During use, at first according to the situation of the heat exchanger tube that is inserted into, the pitch of the spiral band that the width of the width of pre-set belt body, the bar hole of belt body, the width of support bar and belt body form then will be through getting final product in the insertion of the belt body after the screw twisted heat exchanger tube.
The beneficial effects of the utility model are: simple in structure, be easy to processing, augmentation of heat transfer is effective, drag losses is little, be convenient to install and change; To existing heat exchanger, this structure is installed can improves the heat exchange amount in the situation that do not increase heat transfer area, reduce improvement cost; To newly-designed heat exchanger, this structure is installed can be in the situation that certain heat transfer area and the volume that reduces heat exchanger of load that conduct heat, thereby reduces manufacturing cost; There is the occasion of dirt, belt body extracted when changing to be played the effect of taking dirt out of.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the scheme of installation of the utility model and heat exchanger tube.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing
With reference to accompanying drawing:
Described bar hole 11 is evenly distributed along belt body.
Described bar hole 11 is rectangle.
The pitch of the spiral band that the width of the bar hole 11 of the width of described belt body 1, described belt body 1, the width of described support bar 12, described belt body 1 form and installation length and the mounting means of described belt body 1 are all adjusted according to the heat exchanger tube 2 that is inserted into.
During use, at first according to the situation of the heat exchanger tube 2 that is inserted into, the pitch of the spiral band that the width of the bar hole 11 of the width of pre-set belt body 1, belt body 1, the width of support bar 12 and belt body 1 form then will be through getting final product in the belt body 1 insertion heat exchanger tube 2 after the screw twisted.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reaches the equivalent technologies means that design can be expected according to the utility model in those skilled in the art.
