Abstract
The invention provides a U-shaped tubular heat exchanger. The U-shaped tubular heat exchanger comprises a shell, and a plugging plate and a plurality of U-shaped tubes which are arranged in the shell, wherein the plugging plate divides the internal part of the shell into a first chamber and a second chamber, a baffle is arranged in the second chamber and divides the second chamber into a third chamber and a fourth chamber, each U-shaped tube comprises a first end part which is inserted into the plugging plate and is communicated with the third chamber, a second end part which is inserted into the plugging plate and is communicated with the fourth chamber, a straight tube part and a bent part, the straight tube parts and the bent parts are arranged in the first chamber, and the bent parts are twisted tubes. The U-shaped tubular heat exchanger has the advantages that the U-shaped tubes can freely and thermally contracted; since the bent parts of the U-shaped tubes are the twisted tubes, turbulent flow of the bent parts is increased and fouling is prevented.
Description
Technical field
The present invention relates to field of heat exchangers, be specifically related to a kind of pipe heat exchanger.
Background technology
Current pipe heat exchanger, owing to being subject to cold and hot contraction, must be provided with temperature compensation mechanism, such as floating head, filler etc.And easily not easy cleaning of incrustation.
Summary of the invention
Object of the present invention provides U-shaped pipe heat exchanger, solves setting and the not problem of easy cleaning of fouling of temperature compensation mechanism in above-mentioned prior art problem.
The invention provides a kind of U-shaped pipe heat exchanger, comprise housing and be placed in plugging plate and the multiple U-shaped pipe in housing, enclosure interior is divided into the first cavity and the second cavity by plugging plate, the second cavity internal partition, and the second cavity is divided into the 3rd cavity and the 4th cavity, U-shaped pipe comprises the first end that is plugged in plugging plate and be communicated with the 3rd cavity, the second end, straight sections and the turn of bilge that is plugged in plugging plate and is communicated with the 4th cavity, straight sections and turn of bilge are positioned at the first inside cavity, and turn of bilge is swirlyflow tube.
U-shaped pipe heat exchanger provided by the invention, extratubal fluid take the first cavity as U-shaped pipe, tube fluid take the second cavity as U-shaped pipe, and on the tube wall of U-shaped pipe, carry out heat exchange, be fixed on the U-shaped pipe of plugging plate because the present invention adopts end, and then U-shaped pipe can free cold and hot contraction, simultaneously, the turn of bilge of U-shaped pipe adopts swirlyflow tube, increases the turbulent flow of turn of bilge, prevents incrustation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the U-shaped pipe heat exchanger of an embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, U-shaped pipe heat exchanger provided by the invention is described in further detail.
As shown in Figure 1, the invention provides a kind of U-shaped pipe heat exchanger, comprise housing 1 and be placed in plugging plate 3 and the multiple U-shaped pipe 2 in housing 1, housing 1 inside is divided into the first cavity 4 and the second cavity 5 by plugging plate 3, the second cavity 5 internal partitions 6, and the second cavity 5 is divided into the 3rd cavity 7 and the 4th cavity 8, U-shaped pipe 2 comprises the first end 9 that is plugged in plugging plate 3 and is communicated with the 3rd cavity 7, the second end 10 that is plugged in plugging plate 3 and is communicated with the 4th cavity 8, straight sections 11 and turn of bilge 12, straight sections 11 and turn of bilge 12 are positioned at the first cavity 4 inside, turn of bilge 12 is swirlyflow tube.
U-shaped pipe heat exchanger provided by the invention, extratubal fluid take the first cavity 4 as U-shaped pipe 2, tube fluid take the second cavity 5 as U-shaped pipe 2, and on the tube wall of U-shaped pipe 2, carry out heat exchange, be fixed on the U-shaped pipe 2 of plugging plate 3 because the present invention adopts end, and then U-shaped pipe 2 can free cold and hot contraction, simultaneously, the turn of bilge 12 of U-shaped pipe 2 adopts swirlyflow tube, increases the turbulent flow of turn of bilge, prevents incrustation.
The above is only optimal way of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
