A kind of flat radiator
Technical field
The invention belongs to heat exchanger technical field, relate to a kind of flat radiator; Be specially adapted to the heat exchanger of hybrid power, batteries of electric automobile group.
Background technology
Along with more and more higher to environmental protection and energy-conservation requirement, the research and development of hybrid vehicle and electric automobile and market-oriented production are promoted.Because hybrid vehicle, electric automobile power consumption are larger, be the charge-discharge performance that ensures battery pack, will prevent that battery pack is overheated and excessively cold.Battery radiator can be stabilized in suitable temperature range.
Existing battery radiator is made up of several porous aluminum section bars and manifold trunk; Pipe interior detail slotted hole makes water resistance very large, and heat exchange performance is poor; Manifold trunk is non-standard aluminum pipe, and price is higher; By the radiator of the assembling of porous aluminum section bar and nonstandard aluminum pipe, soldering, soldering processes complexity, cost is higher.
Summary of the invention
The invention discloses a kind of flat radiator, to solve the problems such as in prior art, heat exchange performance is poor, price is higher, soldering processes are complicated, cost is higher.
The present invention includes radiator central layer, manifold trunk, demarcation strip; Two of radiator central layer quantity; Longitudinal convex tendon on the symmetrical center line of radiator central layer with vertical manifold trunk, longitudinally convex tendon length is less than radiator central layer length, and on two radiator central layers, longitudinal convex tendon brazing, forms " U " shape heat dissipation channel; On manifold trunk, have two radiator central layer mounting grooves, two radiator central layer mounting groove symmetrical center line on manifold trunk have demarcation strip mounting groove.The radiator central layer mounting groove brazing of the radiator central layer after two brazings and manifold trunk; Demarcation strip is arranged in the demarcation strip mounting groove on manifold trunk, is separated to form inlet channel, water outlet; Form cooling duct along " U " shape heat dissipation channel, water outlet on manifold trunk inlet channel, brazing radiator central layer.
Two radiator core panel edges of the present invention have tongue-and-groove and Tenon, two radiator central layers tongue-and-groove and Tenon interlock brazing alternately.
The present invention also has uniform projection on radiator central layer, the uniform protruding brazing on radiator central layer, and uniform protruding brazing flow-disturbing also supports load-bearing.
Radiator central layer of the present invention is scolder coating aluminium sheet, and when welding, without applied solder paste or solder sheet, part is easy to assembling, and welding procedure is simple.
Good effect of the present invention is: area of dissipation is large, and there is " post " shape turbulence structure centre, and cooling fluid circulation area is large, and flow is large, and damping is little, improves rate of heat exchange, perfect heat-dissipating, and heat-sinking capability is high, and battery pack is remained in required operating temperature range; Inlet/outlet pipe adopts standard aluminum materials in the tube, with low cost.The drawing of the dull and stereotyped employing of core coating aluminum plate stock, only needs welding flux spraying.Assembling is easy, good welding performance." post " turbulence structure ensures that flat radiator meets the intensity of product requirement, can support bearing battery weight.

Embodiment
Describe one embodiment of the present of invention in detail below in conjunction with accompanying drawing.
The embodiment of the present invention as shown in Figure 1, comprises radiator central layer 1, manifold trunk 2, demarcation strip 3; Two of radiator central layer 1 quantity.
As shown in Figure 1 and Figure 2, two radiator central layer 1 edges have tongue-and-groove and Tenon, two radiator central layers 1 tongue-and-groove and Tenon interlock brazing alternately.
As shown in Figure 1, Figure 3, on radiator central layer 1, also there is uniform projection, the uniform protruding brazing on radiator central layer 1, uniform protruding brazing flow-disturbing also supports load-bearing.
As shown in Fig. 1, Fig. 6, on manifold trunk 2, there are two radiator central layer 1 mounting grooves; As Figure 1 and Figure 4, two radiator central layers, the 1 mounting groove symmetrical center line on manifold trunk 2 has demarcation strip 3 mounting grooves; Radiator central layer 1 after two brazings and the radiator central layer 1 mounting groove brazing of manifold trunk 2; Demarcation strip 3 is arranged in the demarcation strip mounting groove on manifold trunk 2, is separated to form inlet channel, water outlet; Form cooling duct along " U " shape heat dissipation channel, water outlet on manifold trunk 2 inlet channels, brazing radiator central layer 1.
As shown in Figure 1, shown in Figure 5, longitudinal convex tendon shown in the D-D on the symmetrical center line of radiator central layer 1 with vertical manifold trunk 2 analyses and observe, longitudinally convex tendon length is less than radiator central layer 1 length, and on two radiator central layers 1, longitudinal convex tendon brazing, forms " U " shape heat dissipation channel.
Radiator central layer 1 is scolder coating aluminium sheet, and when welding, without applied solder paste or solder sheet, part is easy to assembling, and welding procedure is simple.
