Description
Technical field
The utility model relates to a kind of touching type operation screen, is specifically related to a kind of heat sink for touching type operation screen.
Background technology
Touching type operation screen has use widely in the plant equipment of all trades and professions, if touching type operation screen uses in the working environment of normal temperature, just need not lower the temperature, if use in the working environment (as glass calendering industry, Die Casting Industry etc.) of high temperature, just must lower the temperature.
Mainly contain two kinds of modes to the cooling measure of touching type operation screen at present, a kind of is the mode adopting fin to add fan, and another kind is the mode utilizing water or other liquid cools.Fin adds the mode of fan, comprise and be much used for the machine components of drive fan, any one in these parts breaks down and all likely causes the irregular working of fan, cannot normally lower the temperature, in addition, fan send into air in steam and dust, and these steam and dust can cover on a heat sink and finally make the component capabilities of cooling system reduce and damage these parts; The shortcoming of the mode of water or other liquid cools is utilized to be, compared with common fin, the thermal resistance of heat radiation obtains minimizing, but due to the volume of heat pipe large, the design of cooling slide glass will be subject to the restriction of heat pipe shape, and the heat of touching type operation screen is by the passive conduction of heat pipe convection type, cooling efficiency is not thoroughly improved, in addition, because the processing technology of heat pipe inner capillary tube requires higher, cause the cost of heat pipe also higher, have impact on actual application.
Summary of the invention
The purpose of this utility model is to provide a kind of heat sink for touching type operation screen, simple and practical, and utilize semiconductor chilling plate to be distributed by heat very soon, cooling efficiency is high, good cooling effect.
The technical solution adopted in the utility model is: a kind of heat sink for touching type operation screen, comprise heat insulating box 1, operation screen 2, semiconductor chilling plate 3 and radiator 4, heat insulating box 1 is provided with screen installing hole 11 and sheet installing hole 12, operation screen 2 is arranged in screen installing hole 11, semiconductor chilling plate 3 is arranged in sheet installing hole 12, the chill surface of semiconductor chilling plate 3 is arranged on the inside of heat insulating box 1, radiating surface is arranged on the outside of heat insulating box 1, and radiator 4 is arranged on the radiating surface of semiconductor chilling plate 3.
Heat-conducting silicone grease is provided with between the radiating surface of described semiconductor chilling plate 3 and radiator 4.
The utility model compared with prior art has following beneficial effect: simple and practical, utilizes semiconductor chilling plate to be distributed by heat very soon, and cooling efficiency is high, good cooling effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of heat sink for touching type operation screen, comprise heat insulating box 1, operation screen 2, semiconductor chilling plate 3 and radiator 4, heat insulating box 1 is provided with screen installing hole 11 and sheet installing hole 12, operation screen 2 is arranged in screen installing hole 11, semiconductor chilling plate 3 is arranged in sheet installing hole 12, the chill surface of semiconductor chilling plate 3 is arranged on the inside of heat insulating box 1, radiating surface is arranged on the outside of heat insulating box 1, radiator 4 is arranged on the radiating surface of semiconductor chilling plate 3, heat-conducting silicone grease is provided with between the radiating surface of semiconductor chilling plate 3 and radiator 4.
Operation principle is as follows: after semiconductor chilling plate energising, chill surface absorbs the heat in heat insulating box, and heat distributes by radiating surface and radiator, and the temperature in heat insulating box is reduced, thus to operation screen cooling, allows operation screen work in suitable temperature.
