Abstract
The utility model relates to a microwave oven is with high-voltage diode that dispels heat, including the diode chip, there is the ground terminal one end of diode chip through the pin connection, and the other end of diode chip has the inserted sheet terminal through the pin connection, still includes the heat dissipation aluminum sheet, the heat dissipation aluminum sheet is the heliciform and encircles and fix on the lead wire at diode chip both ends. The utility model discloses a heat dissipation aluminum sheet heliciform encircles on the lead wire at diode chip both ends, has greatly increased the heat radiating area of lead wire, can reach and accelerate radiating effect. The heat dissipation aluminum sheet has the advantages of simple and small structure, low manufacturing cost, no change of the original structure of the high-voltage diode due to the structure and the installation position, increase and reduction of the area of the spiral heat dissipation aluminum sheet according to heat dissipation requirements, and effective prevention of loss caused by burning out of the high-voltage diode due to overheating caused by large and small power on a microwave oven.
Description
Technical field
The utility model relates to high-voltage diode field, is specially the high-voltage diode with better heat sinking function for a kind of microwave oven.
Background technology
At present, the microwave oven development of selling is on the market maked rapid progress, new function emerges in an endless stream, constant is that existing microwave oven operation principle is all worked by magnetron as magnetron provides 4KV high pressure by the voltage multiplying rectifier loop forming taking high-tension transformer secondary winding, high-voltage capacitance and high-voltage diode, thereby provides heat for the food in microwave oven cavity.As shown in Figure 2, on existing micro-wave oven high-voltage diode, there is no good radiator structure, individual little because its power is large, can cannot shed by accumulation amount of heat, therefore very easily damage, What is more can occur due to the overheated and on fire situation of high-voltage diode.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of microwave oven high-voltage diode with high-efficient radiating function.
The utility model is a kind of microwave oven heat radiation high-voltage diode, comprise diode chip for backlight unit, one end of described diode chip for backlight unit is connected with earth terminal by lead-in wire, the other end of diode chip for backlight unit is connected with filling-in bit terminal by lead-in wire, it also comprises radiating aluminium sheet, and described radiating aluminium sheet is in the shape of a spiral around being fixed on the lead-in wire at diode chip for backlight unit two ends.
The beneficial effects of the utility model are: radiating aluminium sheet helical form of the present utility model is looped around on the lead-in wire at diode chip for backlight unit two ends, have greatly increased the area of dissipation of lead-in wire, can reach the effect of accelerating heat radiation.This radiating aluminium sheet is simple in structure small and exquisite, cost of manufacture is low, itself structure and installation site also do not change high-voltage diode original structure, spiral helicine radiating aluminium sheet area can need increase and reduce according to heat radiation, and that can effectively prevent on microwave oven that high-voltage diode causes because the large individuality of power is little overheatedly burns out caused loss.
Brief description of the drawings
Be described in further detail with regard to embodiment of the present utility model below in conjunction with accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is existing micro-wave oven high-voltage diode structure schematic diagram.
Embodiment
With reference to heat radiation high-voltage diode for a kind of microwave oven shown in Fig. 1, comprise diode chip for backlight unit 1, one end of described diode chip for backlight unit 12 is connected with earth terminal 3 by going between, the other end of diode chip for backlight unit 12 is connected with filling-in bit terminal 4 by going between, it also comprises radiating aluminium sheet 5, and described radiating aluminium sheet 5 is in the shape of a spiral around being fixed on the lead-in wire 2 at diode chip for backlight unit 1 two ends.
The above; it is only the better embodiment of the utility model; but the utility model protection range is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore the utility model protection range is as the criterion with the protection range of claims.
