Abstract
The utility model belongs to a thin-sheet heat exchanger in water-heating equipment comprising an upper cover plate (4) and a lower cover plate (6). A spiral thin-sheet heat exchange slice (6) has two closed ends and is positioned between the upper cover plate (4) and the lower cover plate (6). The upper border and lower border of the heat exchange slice (6) are respectively welded with the upper cover plate and the lower cover plate and then they are surrounded by the upper cover plate and the lower cover plate to form two sealed cavities. At the same time, water pipe connectors (1) for entering water and discharging water are placed on the two sealed cavities. The thin-sheet heat exchanger makes use of the spiral thin-sheet heat exchange slice and the sealed cavities formed by welding the upper plate and the lower plate. Therefore, the thin-sheet heat exchanger greatly extends time and path of heat exchange between hot liquid and cold liquid and increases heat exchange efficiency.
Description
Technical field
The utility model belongs to a kind of plumbing technical field, particularly a kind of plate exchanger.
Background technology
It is a lot of to have the heat exchanger kind that is used for the cold and hot liquids heat-shift now, but is to comprise plate type heat exchanger or calandria heat exchanger substantially, and the board-like cavity of these two kinds of heat exchangers or comb and housing do not form loop, and the heat exchange path is very short, and heat exchange efficiency is lower.
Summary of the invention
The utility model purpose is a kind of plate exchanger of design, and this heat exchanger greatly improves heat exchange efficiency by prolonging the heat exchange path.
Specifically, a kind of plate exchanger, comprise upper cover plate (4) and lower cover (6), laminar heat exchanging fin (6) closed at both ends of spiraling and place upper cover plate (4) and lower cover (6) between, and the upper and lower edge of heat exchanging fin (6) is surrounded the cavity that forms two sealings with upper and lower cover plate welding back by cover plate up and down respectively, on two closed cavities, be equipped with simultaneously as water inlet or water outlet water pipe head (1).
For guaranteeing in the energising device, to use security of the present utility model, on upper and lower cover plate, also has insulating barrier (5).
The utility model has greatly prolonged the time and the heat exchange path of cold and hot liquids heat exchange owing to utilize the thin heat exchanger fin of spiral fashion so and the cavity of upper and lower plate welding formation sealing, has improved heat exchange efficiency.For example, the hot water temperature that preheating advances into interchanger is 35 ℃, and the cold water temperature that enters is 4 ℃, and the hot water that carries out flowing out in the cold water pipe after the heat exchange becomes 33 ℃, and cold water temperature raises and reaches 29 ℃.
Description of drawings
Fig. 1 is the utility model lateral plan.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
A kind of plate exchanger, comprise upper cover plate (4) and lower cover (6), laminar heat exchanging fin (6) closed at both ends of spiraling and place upper cover plate (4) and lower cover (6) between, and the upper and lower edge of heat exchanging fin (6) is surrounded the cavity that forms two sealings with upper and lower cover plate welding back by cover plate up and down respectively, on two closed cavities, be equipped with simultaneously as water inlet or water outlet water pipe head (1).On upper and lower cover plate, also has heat insulation layer (5).Be welded as a whole by sealing ring (2) and cushion block (3) between water pipe head (1) and the upper and lower cover plate.
This heat exchanger is mainly used in heat-shift between the cold and hot liquids, cold liquid is entered by middle water nozzle, flow out by the side water nozzle, hot liquid is entered by the opposite side water nozzle, flowed out by middle water nozzle, cold liquid will carry out exchange heat by thin heat exchanging fin with hot liquid, adopts welding between heat exchanging fin and the upper and lower cover plate, heat exchanging fin is selected copper sheet and thin as far as possible for use, but based on firm.
Claims (2)
1, a kind of plate exchanger, it is characterized in that comprising upper cover plate (4) and lower cover (6), laminar heat exchanging fin (6) closed at both ends of spiraling and place upper cover plate (4) and lower cover (6) between, and the upper and lower edge of heat exchanging fin (6) is surrounded the cavity that forms two sealings with upper and lower cover plate welding back by cover plate up and down respectively, on two closed cavities, be equipped with simultaneously as water inlet or water outlet water pipe head (1).
2, a kind of plate exchanger according to claim 1 is characterized in that also having heat insulation layer (5) on upper and lower cover plate.
