Description

A kind of large power, electrically heat dissipation device
Technical field
The utility model relates to power technique fields, is specifically related to a kind of large power, electrically heat dissipation device.
Background technology
In the course of the work, the components and parts such as switch transistor rectifier bridge are comparatively large due to self-heating amount for large power supply, have a strong impact on device useful life, need to dispel the heat to it timely and effectively.Usually fixed by power component with on fin, fin and air contact surfaces amass large, and self thermal resistance is little, can distribute heat in surrounding air.The built-in axial flow blower of usual employing takes the heat distributed to cabinet outside, and introduces the lower air of temperature, realizes the cooling to equipment.
Air cooling heat dissipation equipment is comparatively simple, but fin volume mass is comparatively large, affects the use of equipment.What is more important, adopts this kind of radiating mode, needs to mainframe box perforate so that air circulation, and this just makes the degree of protection of the source of welding current lower, when operating mode is severe, as in mine, because dust enters welding machine, decreases the useful life of equipment.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved in the utility model is, provides a kind of liquid-cooling heat radiation mode, without the need to cabinet punching, fan radiating, no dust pollution, fail safe is high, falls apart except the large power, electrically heat dissipation device of heat with chassis shell mates.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of large power, electrically heat dissipation device, comprise cabinet, heating panel is provided with in described cabinet, described heating panel is provided with power device, temperature relay, described heating panel entrance point connects the port of export of cooling fluid storage box by the second flexible pipe, the described heating panel port of export connects water pump by the first flexible pipe, described water pump connects heat-conducting plate entrance point by the 3rd flexible pipe, described heat-conducting plate is placed on semiconductor chilling plate, described semiconductor chilling plate is fixed on case side wall, the described heat-conducting plate port of export connects cooling fluid storage box entrance point by the 4th flexible pipe.
Above-mentioned large power, electrically heat dissipation device, described cooling fluid storage box is fixed on case side wall.
Above-mentioned large power, electrically heat dissipation device, described cooling fluid storage box is provided with the liquid injection hole stretching out case side wall.
The advantage of the utility model large power, electrically heat dissipation device is:
1, the utility model large power, electrically heat dissipation device, cabinet inside components and parts are isolated from the outside, outside dust, moisture are difficult to enter inside, thus the components and parts life-span minimizing because the factors such as dust moisture cause is avoided, the adverse effects such as radiating effect variation, relative to traditional welding machine utilizing blower fan forced convertion, welding machine significantly improves useful life.
2, the utility model large power, electrically heat dissipation device, the heat part in cooling water is transferred in casing via semiconductor chilling plate, and cabinet, by naturally cooling, distributes heat in external environment.Other a part of heat storage in cooling water is in cooling water, and because cooling fluid storage box is connected with cabinet, its heat also can be dispersed into external environment by casing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1, as shown in Figure 1, a kind of large power, electrically heat dissipation device, comprise cabinet 7, heating panel 1 is provided with in described cabinet 7, described heating panel 1 is provided with power device 2, temperature relay 13, described heating panel 1 entrance point connects the port of export of cooling fluid storage box 3 by the second flexible pipe 10, described heating panel 1 port of export connects water pump 4 by the first flexible pipe 9, described water pump 4 connects heat-conducting plate 5 entrance point by the 3rd flexible pipe 11, described heat-conducting plate 5 is placed on semiconductor chilling plate 6, described semiconductor chilling plate 6 is fixed on cabinet 7 sidewall, described heat-conducting plate 5 port of export connects cooling fluid storage box 3 entrance point by the 4th flexible pipe 12.
Heating panel 1 is made up of the sheet metal that heat conductivility is good.There is the duct for cooling liquid flow sheet metal inside, and cooling liquid flows through this duct and dispels the heat to it.Because power device 2 is directly fixed on heating panel 1, for improving electrical insulation properties, need guarantee that power device heating panel and its any one lead-out terminal insulate, thus, heating panel 1 and the binding post electric insulation in electric loop.
Power device 2 refers to high-power switch tube, rectifier cell etc. for power conversion, and this class component in use caloric value is comparatively large, needs to dispel the heat to it in time.
Described cooling fluid storage box 3 is fixed on cabinet 7 sidewall, and described cooling fluid storage box 3 is provided with the liquid injection hole 8 stretching out cabinet 7 sidewall, and convenient operation person increases cooling fluid and observation real-time level for it.
During large power, electrically heat dissipation device work of the present invention, its heat conduction path is: power device 2 is sent out heat thermogenetic and is delivered on heating panel 1 by its radiating bottom plate by heat conductive silica gel, be transported in heating panel 1 by cooling water lower for temperature in cooling fluid storage box 3 by the second flexible pipe 10 by 24V DC water pump 4, the heat then taken out of in heating panel 1 through the first flexible pipe 9, the 3rd flexible pipe 11 arrives in heat-conducting plate 5.Heat-conducting plate 5 is connected with semiconductor chilling plate 6, and semiconductor chilling plate 6 is fixed on cabinet 7 sidewall, is delivered to by heat in metal chassis 7, and reduce the temperature of heat-conducting plate 5, thus the temperature flowing through the cooling liquid of heat-conducting plate 5 is reduced.Cabinet 7, by naturally cooling, distributes heat in external environment.Other a part of heat storage in cooling water is in cooling water, and because metal cooling fluid storage box 3 is connected with cabinet 7, its heat also can be dispersed into external environment by cabinet 7.Cooling water, after temperature reduces, flows back to cooling liquid storage box 3.When heating panel 1 temperature is more than 70 DEG C, temperature relay 13 action, forces to quit work.Said process and so forth, reaches the object to heating panel cooling.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in essential scope of the present utility model, the change made, change, interpolation or replacement, all should belong to protection range of the present utility model.
