Abstract
The utility model discloses a heat exchanger of a continuous spiral flow guiding plate. Due to structural characteristics of an existing continuous spiral flow guiding plate, a flow guiding cylinder can not be arranged at an inlet and an outlet like a bow-shaped baffle plate so that fluid retention zones are formed among an inlet pipe, an outlet pipe and a pipe plate. Two heat exchanging pipes on the retention zones can not be fully used so that heat exchanging effect of the overall heat exchanger is affected. In order to overcome the defects of the continuous spiral flow guiding plate, the continuous spiral flow guiding plate which is cut on the circumference is arranged among the inlet pipe, the outlet pipe and the pipe plate of a shell side. A barrier-free ring-shaped channel is formed between a shell body and a pipe bundle laying zone. Fluid on the two places can be revolved, also can converge into a main flow field and can flow out of the heat exchanger shell body through the shell-side outlet pipe so that heat exchanging effect of the overall heat exchanger is improved.
Description
Technical field
The utility model relates to the heat-exchange apparatus that uses in the industrial production.
Background technology
A kind of state-of-the-art technology of heat-exchange apparatus is the continuous helical deflector heat exchanger, and its design feature is in a heat exchanger shell, and the spiral deflector that is used as water conservancy diversion is continuous helicoid.This technology has a lot of advances, its weak point is: because the relation of continuous helical deflector structure characteristics and fluid motion form, can not resemble and add guide shell in inlet and outlet the segmental baffle, cause to reach between outlet and the port of export tube sheet between inlet tube and the entrance point tube sheet and have the fluid retention district, the fluid of stagnant area, two places is difficult to normally from the inlet pipes continuous helical deflector of flowing through, and from the outlet outflow heat exchanger, so that the heat exchanger tube of stagnant area, two places can not be fully used, thereby affect whole heat exchanger heat transfer effect.
Summary of the invention
For improving the above-mentioned deficiency of continuous helical deflector heat exchanger, the utility model provides a kind of heat exchanger that improves the continuous helical deflector structure.Both with the continuous helical deflector in the heat exchanger, be designed to different structures according to the position at its place is different.
Continuous helical deflector between heat exchanger shell pass inlet tube and the outlet adopts the structure of complete outer circular.
To the continuous helical deflector that periphery cuts be set between shell side inlet tube and the entrance point tube sheet and between shell side outlet and the port of export tube sheet, between housing and tube bank cloth area under control, form a clog-free circular passage.
Periphery cutting continuous helical deflector is set between shell side inlet tube and the entrance point tube sheet and between shell side outlet and the port of export tube sheet, the fluid at above-mentioned two places can be rotated, also can import the main flow field, and from shell side outlet outflow heat exchanger housing.
The fluid that reaches between shell side inlet tube and the entrance point tube sheet between shell side outlet and the port of export tube sheet waltzs through remittance main flow field, circular passage, the heat exchanger tube at above-mentioned two places is fully used, thereby the heat transfer effect of whole heat exchanger is improved.
Above-mentioned continuous helical deflector structure can be used for fixed tube-sheet exchanger, movable tube sheets heat exchanger and U-shaped heat exchange of heat pipe.
Description of drawings
Accompanying drawing 1 is the heat exchanger tube schematic diagram of a kind of embodiment of the utility model.
Among the figure, 1, front-end pipe box, 2, the entrance point tube sheet, 3, periphery cutting continuous helical deflector, 4, the shell side inlet tube, 5, the continuous helical deflector, 6, housing, 7, heat exchanger tube, 8, backstay, 9, shell side outlet, 10, port of export tube sheet, 11 rear end headers, Fig. 2 are A-A and the B-B profiles of Fig. 1,12, circular passage, 13, tube bank cloth area under control.
The specific embodiment
As shown in drawings, the utility model continuous helical deflector heat exchanger comprises front-end pipe box (1), rear end header (11), the part that consists of heat exchanger tube has entrance point tube sheet (2), port of export tube sheet (10), periphery cutting continuous helical deflector (3), continuous helical deflector (5), heat exchanger tube (7), backstay (8), housing (6), shell side inlet tube (4) shell side outlet (9).
Periphery cutting continuous helical deflector (3) is set between shell side inlet tube (4) and the entrance point tube sheet (2) and between shell side outlet (9) and the port of export tube sheet (10), makes the housing at above-mentioned two places and restrain to form a clog-free circular passage (12) between the cloth area under control.
The utility model continuous helical deflector structure can be used for fixed tube-sheet exchanger, movable tube sheets heat exchanger and U-shaped heat exchange of heat pipe.
Claims (1)
1. continuous helical deflector heat exchanger, comprise front-end pipe box, rear end header, the part that consists of heat exchanger tube has entrance point tube sheet, port of export tube sheet, continuous helical deflector, heat exchanger tube, backstay, housing, the shell side inlet tube, the shell side outlet, it is characterized in that between shell side inlet tube and the entrance point tube sheet and shell side outlet and port of export tube sheet between periphery cutting continuous helical deflector is set, the housing that makes above-mentioned two places with restrain clog-free circular passage of formation between the cloth area under control.
