Abstract
A kind of U-tube heat exchanger, including housing and the U-tube bundle being arranged in housing, U-tube bundle includes several U-shaped heat exchanger tubes, described U-tube bundle is supported in housing by deflection plate and tube bundle support structure, deflection plate is fixed on the straight flange of U-tube heat exchanger tube, and tube bundle support structure is fixed on the U-shaped region of U-tube bundle.Supporting construction described in the utility model can make full use of the heat exchange area in U-shaped region, without flow dead.
Description
Technical field
This utility model relates to a kind of heat-exchanger rig, especially relates to a kind of U-tube heat exchanger.
Background technology
The U-shaped region of the afterbody of existing U-tube heat exchanger typically uses monoblock gripper shoe to be supported, therefore Fig. 1 is seen in the front portion that gripper shoe must be placed at U-shaped region, so makes formation flow dead, U-shaped region, it is impossible to participates in heat exchange, causes the waste of heat exchange area.If being not provided with gripper shoe, then can utilize U-shaped region heat exchange area, but heat exchange efficiency is low, and easily cause vibration.
Utility model content
The purpose of this utility model is the problem for solving the heat exchanger heat exchange area waste that existing U-tube heat exchanger tail support plate causes, it is provided that a kind of U-tube heat exchanger.
This utility model is the deficiency solving above-mentioned technical problem, be the technical scheme is that
nullA kind of U-tube heat exchanger，Including housing and the U-tube bundle being arranged in housing，U-tube bundle includes several U-shaped heat exchanger tubes，Described U-tube bundle is supported in housing by deflection plate and tube bank tail support structure，Deflection plate is fixed on the straight flange of U-shaped heat exchanger tube，Tube bank tail support structure is fixed on the U-shaped region of U-tube bundle，Described U-shaped region refers to the arc section of U-shaped heat exchanger tube in U-tube bundle，Described afterbody tube bundle support structure includes arc square steel and corrugated grille strip，The two ends of corrugated grille strip are each attached on arc square steel，Corrugated grille strip is equidistantly arranged in parallel on the chord length direction of arc square steel，Corrugated grille strip matches with tube bank cross section，Corrugated grille strip is all vertical with the same diameter of arc square steel，The protrusion direction of adjacent two corrugated grille strips is contrary，The center of circle of adjacent two corrugated grille strip high spots is located along the same line，Its protrusions middle-range is from the clamping hole of two farthest composition clamping U-shaped heat exchanger tubes，Closest type has become the passage carrying out heat exchange between U-shaped heat exchanger tube，Vibration can be avoided not only by clamping action，And leave free air space and can sufficiently utilize U-tube bundle afterbody heat exchange area.
Tube bundle support structure includes corrugated grille strip and for fixing the arc square steel of corrugated grille strip, it is welded to connect between corrugated grille strip and arc square steel, in practical set, every layer of heat exchanger tube and corrugated grille strip are sequentially installed, corrugated grille strip contacts in circumferential portion with U-shaped region heat exchanger tube tool, therefore while firmly support U-shaped region heat exchanger tube prevents its vibration, do not affect the flowing of fluid, and because of the flow-disturbing effect of corrugated square steel, therefore it has invigoration effect to the heat exchange in U-shaped region.
The beneficial effects of the utility model are: supporting construction described in the utility model can make full use of the heat exchange area in U-shaped region, without flow dead.Supporting construction described in the utility model has obvious flow-disturbing effect, therefore can strengthen the heat exchange in U-shaped region, improves heat transfer effect.In utility model Novel support structure of the present invention, U-shaped region heat exchanger tube is played firm support by corrugated grille strip, it is to avoid U-shaped region tube bundle vibration.

Detailed description of the invention
Shown in figure, detailed description of the invention is as follows:
nullA kind of U-tube bundle formula radiator，Including housing 1 and the U-tube bundle 2 being arranged in housing 1，U-tube bundle 2 includes several U-shaped heat exchanger tubes 6，Described U-tube bundle 2 is supported in housing 1 by deflection plate 3 and tube bundle support structure 5，Deflection plate 3 is fixed on the straight flange of U-shaped heat exchanger tube，Tube bundle support structure 5 is fixed on the U-shaped region of U-tube bundle，Described U-shaped region refers to the arc section of U-shaped heat exchanger tube in U-tube bundle，Described tube bundle support structure 5 includes arc square steel 5-2 and corrugated grille strip 5-1，The two ends of corrugated grille strip 5-1 are each attached on arc square steel 5-2，Corrugated grille strip 5-1 is arranged in parallel on the chord length direction of arc square steel 5-2 with identical spacing，Corrugated grille strip 5-1 matches with tube bank 2 cross sections，Corrugated grille strip is all vertical with the same diameter of arc square steel，The protrusion direction of adjacent two corrugated grille strips is contrary，The center of circle of adjacent two corrugated grille strip high spots is located along the same line，Its protrusions middle-range is from the clamping hole of two farthest composition clamping U-shaped heat exchanger tubes，Closest type has become the passage carrying out heat exchange between U-shaped heat exchanger tube，Vibration can be avoided not only by clamping action，And leave free air space and can sufficiently utilize U-tube bundle afterbody heat exchange area.
The flowing in U-shaped region is unaffected, there is not flow dead, tube bundle support structure 5 includes corrugated grille strip and for fixing the arc square steel of corrugated grille strip, it is welded to connect between corrugated grille strip and arc square steel, in practical set, every layer of heat exchanger tube and corrugated grille strip are sequentially installed, corrugated grille strip contacts in circumferential portion with U-shaped region heat exchanger tube tool, therefore while firmly support U-shaped region heat exchanger tube prevents its vibration, do not affect the flowing of fluid, and because of the flow-disturbing effect of corrugated square steel, therefore it has invigoration effect to the heat exchange in U-shaped region.
Technical scheme cited by this utility model and embodiment non-limiting, be equal to the technical scheme cited by this utility model and embodiment or effect same approach be all in the range of this utility model is protected.
