Abstract
The utility model provides an electrical heat sink, and relates to the field of electrical heat sink manufacturing. The electrical heat sink comprises a left assembling box, a right assembling box, a plurality of cooling fins, a lower end air inlet layer and an upper end heat dissipation layer. The cooling fins are arranged from front to back at intervals. The peripheries of the cooling fins are fixedly arranged inside the assembling boxes, the air inlet layer and the heat dissipation layer in a clamping and embedded mode, and a sealing cavity is formed. Air inlet holes are formed in the air inlet layer. Heat dissipation holes are formed in the heat dissipation layer. The cooling fins are arranged in a concave-convex-shaped and bent mode. Two cooling fins arranged on the front surface and the back surface are aluminum alloy sheets and the cooling fins arranged in the middle at intervals are chromium alloy sheets. According to change of the structure of the cooling fins and selection of chromium alloy materials, a heat dissipation effect of the cooling fins is greatly improved, and the service lives of the cooling fins are greatly prolonged.
Description
Technical field
The utility model relates to electric radiator and makes the field.
Background technology
The fin of electric radiator on the market generally is divided three classes at present: one, metal etch Electric radiant Heating Film, its no decoration surface layer, the heating efficiency height, power connection burns easily, burns film easily, opens circuit, ftracture between composite bed, cause that metal forming comes off, short circuit, because the reliability of technology difference has not had production abroad, its shortcoming is that also tinsel and insulating substrate are compound not firm, caused the heating circuit damaged in etching process, the long-term use forms hidden failure; Protection printing ink covers bad, causes latticed heating circuit, and the circuit heat conductivility reduces, and easily ablates; Because the metal forming village is thin excessively, the power connection flow conductivity is poor, easily generates heat, burns, and becomes the defective that causes of technology for this reason, thoroughly solves yet so far.
Two, tin oxide (tunica albuginea) Electric radiant Heating Film, its insulating substrate serviceability temperature＞600 ℃, tin ash Electric radiant Heating Film serviceability temperature＜300 ℃, architectural surface is arranged, and heating efficiency is lower slightly, and power attenuation is serious, easily burn film, fragile, the assembling loss is big, does not have this technology abroad, because of the fault rate height, the domestic beginning eliminated, and its shortcoming is that also the tin ash Electric radiant Heating Film is aging, and power attenuation is serious; Tin dioxide film belongs to inorganic fragile material, and different with the insulation board expansion rate, will produce micro-crack after the heating repeatedly, becomes to burn film hidden danger; Spraying tin dioxide film uneven distribution will cause same the plate flow distribution inequality that powers on, and the degree of aging difference causes and burns film, adopts the fixing large-current electric utmost point of staple, is a kind of insecure mode of connection, easily causes the interpolar sparking, blows the silver slurry.
Three, carbon crystal electrothermo film, its insulating substrate serviceability temperature＞600 ℃, carbon crystalloid Electric radiant Heating Film serviceability temperature＜200 ℃, the no decoration surface layer, heating efficiency height, power attenuation are seriously, easier burning film, power connection oxidation burn.
The external low temperature small-power that only is used for heats, and is domestic superseded.Its shortcoming is that also carbon crystalloid Electric radiant Heating Film does not possess oxidation owing to the easy oxidation of graphite and do not possess high-temperature use, so its power density is less than 0.3w/cm2; The printing technology of Electric radiant Heating Film easily causes uneven distribution and printing defects; Carbon epitaxial and insulation expansion rate difference are excessive, are easy to crack and peel off and burn film; Because insulation expansion easily causes the burning film, so the carbon film heating board can only adopt floating type bound edge, bulk strength is low, and is fragile.
Have the fin of electric radiator on the market in addition now, area of dissipation is little, and radiating effect is poor, haves much room for improvement.
Summary of the invention
The utility model provides a kind of good heat dissipation effect at the deficiencies in the prior art, the electric radiator of long service life.
The utility model is for solving the problems of the technologies described above, provide following technical scheme: a kind of electric radiator, assemble box, some fin, lower end air inlet layer, upper end heat dissipating layer about comprising, described fin arranges at interval from front to back, all around fixedly inlay card in assembling box, air inlet layer and heat dissipating layer, form a sealed chamber, described air inlet layer and heat dissipating layer offer air admission hole and louvre respectively, it is characterized in that described fin concave-convex bending arranges, two fin that are positioned at front and rear surfaces are aluminum alloy sheet, and the fin of midfeather setting is the evanohm sheet.
As further improvement of the utility model, described heat dissipating layer upper end is provided with a hollow chamber, and the chamber top evenly offers several through holes.Can be at a certain amount of water of the indoor injection of hollow cavity by this kind setting, the heat that discharges by fin makes its evaporation, and overflows in through hole, increases air humidity, effectively prevents indoor too dry.
Described assembling box is provided with microcomputer controller.
Beneficial effect: the utility model is by the structure of change fin, and the selection chromium alloy material, radiating effect and the service life of having improved fin greatly.
