The utility model proposes a kind of source of welding current 10.
Fig. 1 is the structural representation of this utility model source of welding current one embodiment; Fig. 2 is the structural representation of radiator in Fig. 1.
In this utility model embodiment, this source of welding current 10 includes cabinet 11 and the driving power supply 12 being arranged in this cabinet 11, the described source of welding current 10 also includes radiator 13, described radiator 13 includes the First Heat Exchanger 131 being arranged in described cabinet 11 and the external refrigerator 132 being arranged at outside described cabinet 11, described external refrigerator 132 includes compressor 132a and the second heat exchanger 132b, described compressor 132a, First Heat Exchanger 131 and the second heat exchanger 132b and is sequentially communicated the closed circuit forming a coolant.
The technical solution of the utility model by arranging First Heat Exchanger 131 in cabinet 11, one external refrigerator 132 is set outside cabinet 11, coolant is imported and absorbs the heat driving power supply 12 to give out in First Heat Exchanger 131 by external refrigerator 132, then flow in described external refrigerator 132, after being compressed by compressor 132a, coolant is imported in the second heat exchanger 132b, so that heat is distributed, avoid the dust outside cabinet 11 because of cross-ventilation, steam etc. are brought into and are driven the internal problem causing short circuit or device damage of power supply 12, improve the service life of the source of welding current 10.
In the present embodiment, described external refrigerator 132 is similar with the refrigeration principle of air-conditioner with the refrigeration principle that described First Heat Exchanger 131 realizes.Specifically, when described radiator 13 works, after coolant is compressed by compressor 132a, form the coolant of High Temperature High Pressure, the coolant of High Temperature High Pressure flows in the second heat exchanger 132b, coolant discharges substantial amounts of heat in the second heat exchanger 132b, and form the coolant of low-temp low-pressure, the coolant of low-temp low-pressure flows into and absorbs the heat in cabinet 11 in First Heat Exchanger 131 and flow back in compressor 132a, compressor 132a imports in described second heat exchanger 132b after being compressed by coolant, heat is discharged by coolant, so circulation, so that the heat that described driving power supply 12 discharges discharges to cabinet 11 outside after being absorbed by coolant gradually.
It should be noted that described coolant is similar with the coolant used in air-conditioner, such as freon, difluoromethane, pentafluoroethane etc., described First Heat Exchanger 131 is vaporizer, is used for absorbing heat, and described second heat exchanger 132b is condenser, is used for discharging heat.
It addition, described external refrigerator 132 can be affixed on described cabinet 11, fixed form is that welding, threaded or clamping etc. are all possible. Certainly, described external refrigerator 132 is connected with not fixing with cabinet 11. Described compressor 132a, connecting each through pipeline 130 between First Heat Exchanger 131 and the second heat exchanger 132b, described pipeline 130 can be copper pipe, stainless steel tube, aluminum pipe etc., and certainly, in order to make heat exchange better, copper pipe is preferred embodiment.
Refrigeration modes in above-described embodiment not adopts cross-ventilation heat exchange, and cross-ventilation effect is not strong, and therefore, the cabinet 11 in above-described embodiment can be airtight, certainly allows also to have a small amount of gap. In order to strengthen the refrigeration of described radiator 13, in the present embodiment, described cabinet 11 is arranged in totally enclosed type. So, the cold air within cabinet 11 is outside without distributing to cabinet 11, and the impurity (dust, steam etc.) in extraneous air is without entering in cabinet 11; The refrigerating efficiency of described radiator 13 also gets a promotion.
In view of described cabinet 11 is to arrange in totally enclosed type, in order to strengthen the flowing of air in cabinet 11, to avoid the heat driving power supply 12 to produce to assemble, in the present embodiment, in described cabinet 11, it is additionally provided with the blower fan 14 driving the air in described cabinet 11 to form internal recycle in described cabinet 11. So, when blower fan 14 runs, it is possible to drive air circulation flow in described cabinet 11, the heat that described driving power supply 12 gives out to be easy to distribute to driving in power supply 12 ambient air. So, radiating efficiency is substantially increased.
Described First Heat Exchanger 131 is vaporizer, and for absorbing the heat of surrounding, in order to strengthen the contact area of described First Heat Exchanger 131 and surrounding air, to increase endothermic effect, in the present embodiment, described First Heat Exchanger 131 is fin-tube type heat exchanger. That is, described First Heat Exchanger 131 includes multiple fin be arrangeding in parallel and the coil through the plurality of fin.
On the basis of a upper embodiment, described blower fan 14 is between described First Heat Exchanger 131 and described driving power supply 12. So, blower fan 14 is operationally, it is possible to be blown into by the cold air around First Heat Exchanger 131 to described driving power supply 12, to lower the temperature to described driving power supply 12.
It addition, described First Heat Exchanger 131 can also between described blower fan 14 and described driving power supply 12. So, when described blower fan 14 runs, blower fan 14 can suck the cold air around described First Heat Exchanger 131 the described driving power supply 12 that leads, and the effect driving power supply 12 cooling is given in equally possible realization.
In order to strengthen the radiating effect of described driving power supply 12, in the present embodiment, described driving power supply 12 has a housing, the side towards described First Heat Exchanger 131 of described housing offers the first vent, and the side deviating from described First Heat Exchanger 131 of described housing offers the second vent. So, the heat that described driving power supply 12 gives out can pass through described first vent and the second vent distributes rapidly to driving power supply 12 around. So that described First Heat Exchanger 131 absorbs heat rapidly.
It addition, the cold air around described First Heat Exchanger 131 can also be blown into the enclosure interior of described driving power supply 12 by described blower fan 14 by described first vent, then flow out from described second vent, rapidly the heat of described enclosure interior is taken out of.
Although described cabinet 11 is to arrange in totally enclosed type, but the air within cabinet 11 is likely to self have part steam, this part steam is likely on described First Heat Exchanger 131 to form condensation, drive power supply 12 internal if this part condensation enters, it is possible to can cause driving power supply 12 to burn out. In order to prevent the generation of above-mentioned situation, in the present embodiment, described cabinet 11 is internally provided with desiccant, is all possible such as calcium chloride, phosphorus pentoxide, alkali metal oxide etc.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every under inventive concept of the present utility model; utilize the equivalent structure transformation that this utility model description and accompanying drawing content are made, or directly/be indirectly used in other relevant technical fields and be included in scope of patent protection of the present utility model.
