On January 14th, 2009, disclosed application number was that 200820004391.4 utility model patent specification discloses a kind of solar water heater heat-exchanger rig, this heat-exchanger rig is that a kind of column heat exchange unit that is interconnected by some inner chambers constitutes, the outer surface of this column heat exchange unit fixedly radiating fin to increase heat exchange area.But, because this heat-exchanger rig is owing to be many compositions, when being fit into water-heater water tank, for the heat-conducting medium in uniform and the water tank carries out heat exchange, need on tank inner wall, punch and corresponding heat exchange unit fastener is installed to arrange fixedly heat-exchanger rig, it installs and fixes comparatively trouble, reduce the installation production efficiency of water heater, simultaneously, this installation is very easy to cause the blow-by of the tank inner wall of water heater, and after long-time the use, the heat-conducting medium in the water tank is the fastener installing hole seepage inlet water tank heat-insulation layer by heat exchange unit easily, and then the corrosive water tank shell, make water tank lose heat insulation effect.
The utility model content
The purpose of this utility model provides and a kind ofly installs and fixes conveniently, the heat-exchanger rig that heat exchange efficiency is high and the solar water heater that this heat-exchanger rig is installed.
The technical solution of the utility model is: a kind of heat exchanger, this heat exchanger comprises hollow tubing conductor, be the radial heat exchange fin that radially is installed with on the hollow tubing conductor outer surface, it is characterized in that, the end of this heat exchange fin is provided with integrative-structure and is used for interconnective connector.
Described connector is a column, and the diameter of this column is greater than the thickness of heat exchange fin.
Described connector is a plate body, and is T-shaped between this plate body and the heat exchange fin.
Be respectively equipped with the non-toxic anticorrosion layer on the inside and outside surface of described heat exchanger.
The utility model also provides a kind of solar water heater, comprise heat-exchanging water tank, in heat-exchanging water tank, be provided with heat exchanger, this heat exchanger comprises the hollow tubing conductor that is made of aluminum pipe, on the hollow tubing conductor outer surface, be the radial heat exchange fin that radially is installed with integrative-structure, it is characterized in that, be provided with integrative-structure at the end of described heat exchange fin and be used for interconnective connector, interconnect fixing by the connection fastener that is installed on the described connector between the adjacent heat exchanger.
Described connector is a column, and the diameter of this column is greater than the thickness of heat exchange fin.
Described connector is a plate body, and is T-shaped between this plate body and the heat exchange fin.
Described connection fastener is made of special-shaped aluminium, and it comprises a cross connecting plate, and this cross connecting plate is respectively equipped with the draw-in groove that can join with the terminal connector card of heat exchange fin along four limits of its length direction.
Be respectively equipped with the non-toxic anticorrosion layer on the inside and outside surface of described heat exchanger.
Adopt said structure, in water tank, each heat exchanger can be connected into an integral body by the connector on connection fastener and the heat exchanger, simultaneously, pass through the connection fastener distance of separation between each heat exchanger, neat arrangement is installed in the water tank, need not fix corresponding fixture on tank inner wall.Its global shape is with the water tank random variation, only need to be linked as whole heat exchanger during installation and directly put into water tank cavity, it is fixing simple, easy for installation, and, do not destroy the integral sealing structure of water tank, prolonged the service life of water tank greatly, and, the production and assembly speed of water heater can be improved, enhance productivity, reduce the manufacturing cost of solar water heater.
