Abstract

Disclosed is an aluminium alloy radiator. The aluminium alloy radiator comprises a plurality of heat sinks which are made of aluminium alloy and are connected together. The heat sinks are provided with an upper connecting pipe port and a lower connecting pipe port. Electrical heating tubes are arranged in the heat sinks in an inbuilt mode. The heat sinks are further provided with radiating fins which extends along the longitudinal direction. The radiating fins comprises a first radiating fin which is arranged on the front side of each heat sink, a second and a third radiating fins which are arranged on the mid-side of each heat sink, and a fourth and a fifth radiating fins which are arranged on the back side of each heat sink from front to back. Vertical air guide channels are formed among the radiating fins. The upper ends of the second radiating fin and the third radiating fin extend forwards and upwards to form flow deflectors which form front air channel outlets over the top of the first radiating fin. The lower sides of the air guiding channels are air channel inlets. Due to the fact that a plurality of radiating fin units are arranged on the heat sinks and the plurality of radiating fin units form air guiding channels, upcurrent circulation is formed in the air guiding channels, and radiating effect is increased.

Description

A kind of aluminium alloy heat radiator

(1) technical field

The utility model relates to a kind of aluminium alloy heat radiator.

(2) background technology

Radiator is we are used for heating in winter equipment, and it has been divided into several, and is electric heating, hydro-thermal, the defeated heat of steam.

The radiator of electric heating often adopts aluminium alloy to make, the aluminium alloy heat radiator of prior art, after burying electrothermal tube underground on its fin, the mode that employing forms the ventilation cavity at fin increases muscle and goes out area, arranging of cavity of heat radiation is not to arrange up and down, can not effectively generate the ascending air of a heating.

(3) summary of the invention

In order to overcome existing aluminium alloy heat radiator from sending out a deficiency that forms the ascending air heat radiation, the utility model provides a kind of aluminium alloy heat radiator that can spontaneous formation ascending air heat radiation.

The technical scheme in the invention for solving the technical problem is: a kind of aluminium alloy heat radiator, the fin that comprises the aluminium alloy system that several link together, described fin is provided with the connection mouth of pipe, the lower connection mouth of pipe, be embedded with electrothermal tube in the described fin, also be provided with the radiating fin of longitudinal extension on the described fin, described radiating fin comprises the first radiating fin that is positioned at the fin front side from front to back, the second radiating fin of side and the 3rd radiating fin in the fin, of fin rear side scatter hot fin and the 5th radiating fin, form vertical wind guide channel between the described radiating fin, described the second radiating fin and the 3rd radiating fin upper end are extended with flow deflector and cross the outlet of the first radiating fin top formation primary air separating duct to the front upper place, described wind guide channel downside is the air channel import.

Described fin links together with the lower connection mouth of pipe by the upper connection mouth of pipe.

Further, described upper connection mouth of pipe front upper place also is provided with the 6th radiating fin, form a secondary primary air separating duct outlet between described the 6th radiating fin and the 3rd radiating fin, be formed with a upper air duct outlet between described six radiating fins and the 5th radiating fin.

The utility model in use, the whole fin of electrothermal tube energising heating, whole fin drives several groups of radiating fin heating, cold airflow is come in from the air channel import of downside, in wind guide channel, heated by radiating fin, thereby density reduces automatic-ascending after the heating, and last in the past ducting outlet blows out, and the circulation that has formed an ascending air increases radiating effect.

The beneficial effects of the utility model are: have several groups of radiating fins on the fin and form wind guide channel, thereby the circulation that forms a kind of ascending air in wind guide channel has increased radiating effect.

(4) description of drawings

Fig. 1 is the schematic diagram of the fin of an embodiment of the utility model.

Fig. 2 is the air-flow schematic diagram of the fin of an embodiment of the utility model.

(5) specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

By reference to the accompanying drawings 1 and 2, a kind of aluminium alloy heat radiator, the fin that comprises the aluminium alloy system that several link together, described fin is provided with connection mouth of pipe 1A, lower connection mouth of pipe 1B, be embedded with electrothermal tube 2 in the described fin, also be provided with the radiating fin 3 of longitudinal extension on the described fin, described radiating fin comprises the first radiating fin 3A that is positioned at the fin front side from front to back, the second radiating fin 3B of side and the 3rd radiating fin 3C in the fin, of fin rear side scatter hot fin 3D and the 5th radiating fin 3E, form vertical wind guide channel 4 between the described radiating fin, described the second radiating fin and the 3rd radiating fin upper end are extended with flow deflector 5 and cross the first radiating fin top formation primary air separating duct outlet 6A to the front upper place, described wind guide channel downside is air channel import 7.

Described fin links together with lower connection mouth of pipe 1B by upper connection mouth of pipe 1A.

Described upper connection mouth of pipe front upper place also is provided with the 6th radiating fin 3F, form a secondary primary air separating duct outlet 6B between described the 6th radiating fin 3F and the 3rd radiating fin 3C, be formed with a upper air duct outlet 6C between described six radiating fin 3F and the 5th radiating fin 3E.

By reference to the accompanying drawings 2, the utility model in use, the whole fin of electrothermal tube energising heating, whole fin drives 3 heating of several groups of radiating fins, and as shown by arrows, cold airflow is come in from the air channel import 7 of downside, in wind guide channel 4, heated by radiating fin 3, thereby density reduces automatic-ascending after the heating, and last in the past ducting outlet 6A, secondary primary air separating duct outlet 6B, upper air duct outlet 6C blow out, and the circulation that has formed an ascending air increases radiating effect.

Have several groups of radiating fins on the fin of the present embodiment and form wind guide channel, thereby the circulation that forms a kind of ascending air in wind guide channel has increased radiating effect.
