Abstract
The invention discloses a heat exchanger with U-tubes of different tube diameters. The heat exchanger with the U-tubes of different tube diameters comprises a medium inlet, a separating plate, a tube sheet, a baffle plate, a first-type U-tube, a baffle, a second-type U-tube, a tube header, a medium outlet, a housing separating plate and a housing. The left of the housing is provided with the tube sheet, the left of the tube sheet is provided with the tube header, and the upper end of the tube header is provided with the medium inlet; the separating plate is arranged under the medium inlet, and the medium outlet is arranged under the separating plate; the tube plate is provided with the first-type U-tube and the second-type U-tube which are of different tube diameters; the inside of the housing is provided with a baffle plate, and the right top of the housing is provided with the baffle. The first-type U-tube and the second-type U-tube which are of different tube diameters are connected to the tube plate in an expansion mode, so that when medium is insufficient, the first-type U-tube can be filled with the medium due to the relatively low tube diameter and further ensure the heat exchange area of the heat exchanger, and the heat exchange efficiency of the heat exchanger with insufficient medium can be improved.
Description
Technical field
The present invention relates to a kind of heat exchanger, specifically a kind of different tube diameters U-tube heat exchanger.
Background technology
Existing heat exchanger is when medium deficiency, and heat exchanger tube can not filled media completely, causes the heat exchange area of heat exchanger to reduce, and then causes heat transfer effect not good, when medium enters in a large number because impulsive force is comparatively large, heat exchanger tube usually can be made to be out of shape and even break.
Summary of the invention
The object of the present invention is to provide a kind of different tube diameters U-tube heat exchanger, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of different tube diameters U-tube heat exchanger, comprise medium entrance, dividing plate, plate pipe, deflection plate, one analog-U shaped pipe, baffle plate, two analog-U shaped pipes, bobbin carriage, media outlet, case partition and housing, tube sheet is provided with on the left of described housing, bobbin carriage is provided with on the left of tube sheet, bobbin carriage upper end is provided with medium entrance, dividing plate is provided with below medium entrance, dividing plate has media outlet, described tube sheet is provided with case partition, tube sheet is provided with an analog-U shaped pipe and two analog-U shaped pipes, a described analog-U shaped pipe and two analog-U shaped pipes are the different U-tube of two kinds of calibers, deflection plate is provided with in described housing, housing upper right side is provided with baffle plate.
As the further scheme of the present invention: described case partition is weldingly fixed on tube sheet.
As the present invention's further scheme: a described analog-U shaped pipe and two analog-U shaped pipes are fixed on plate pipe by expanded joint.
As the further scheme of the present invention: described deflection plate side and housing bottom surface are 75 ° of angles.
As the further scheme of the present invention: described baffle plate is provided with multiple through hole.
Beneficial effect of the present invention is: the class U-shaped pipe utilizing two kinds of calibers different and two analog-U shaped pipe expanded joints are on tube sheet, when medium is not enough, because the caliber of an analog-U shaped pipe is less, medium so just can be made to be full of pipe shaft, and then ensure that the heat exchange area of heat exchanger, improve the heat exchange efficiency of the heat exchanger when medium is not enough, utilize loose structure on baffle plate to make medium be divided into a plurality of fluids, and then improve the heat exchange efficiency of heat exchanger.
