Abstract

The utility model discloses a large-current water-cooling terminal. The water-cooling terminal comprises a first pipeline made of red copper. The first pipeline is sleeved by a second pipeline made of brass. A fixing ring for connection with a copper bar is arranged on the outer side of the second pipeline. The second pipeline is sleeved by a first insulating sleeve and a second insulating sleeve. The first insulating sleeve and the second insulating sleeve cooperate with each other and are fixed on a housing of a capacitor. The first pipeline and the second pipeline are fixed by brazing, and provided with a filler arranged therebetween. According to the utility model, a filler is arranged to improve the conductivity between the first pipeline and the second pipeline. The second pipeline is made of brass and has a relatively large resistance, and when a current passes through, the second pipe line generates more heat than the first pipeline. The heat radiation is mainly carried out by cooling water, so that heat in the second pipeline needs to be conducted to the first pipeline quickly, and then conducted to the cooling water for radiation.

A kind of resistance to large current mode water-cooling terminal

Technical field

[0001] the utility model belongs to capacitor technology field, specifically a kind of resistance to large current mode water-cooling terminal.

Background technology

Capacitor is electronic component conventional in circuit, large-scale capacitor is because caloric value is large, need to adopt cooling water to carry out cooling electric current wire, at cooling water, be linked into transformer case place water-cooling terminal need to be set, water-cooling terminal comprises the first pipeline of being made by red copper now, logical cooling water in described the first pipeline, the outside of the first pipeline is arranged with a second pipe of being made by brass, second pipe arranged outside is useful on two retainer plates that connect copper bar, described second pipe outside is arranged with the first insulating case and the second insulating case, described the first insulating case and the second insulating case are fixed on capacitor case, existing the first pipeline and second pipe are generally fixed by brazing, solder joint is positioned at the end of the second pipe of capacitor casing, in use, two retainer plates connect copper bar, on copper bar, switch on, electric current passes through second pipe successively, solder joint and the first pipeline, the electric current generally passing through due to water-cooling terminal is larger, therefore caloric value is very large, owing to having gap between the first pipeline and second pipe, therefore the poor effect that heat is transmitted, radiating effect is not very desirable, the general maximum electric currents that can only bear 2000A left and right of existing water-cooling terminal, if electric current strengthens again, so because heat radiation reason water-cooling terminal can be burnt.

Summary of the invention

The utility model is not enough for prior art, and a kind of resistance to large current mode water-cooling terminal is provided, and the radiating effect of this water-cooling terminal is better, can bear larger electric current, and easy to process.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of resistance to large current mode water-cooling terminal, comprise the first pipeline that red copper is made, described the first pipeline outside is arranged with the second pipe that brass is made, second pipe arranged outside is useful on the retainer plate that connects copper bar, described second pipe outside is arranged with the first insulating case and the second insulating case, described the first insulating case and the second insulating case are fixed on capacitor case, described the first pipeline and described second pipe are welded and fixed, between described the first pipeline and described second pipe, be provided with filler.Between the first pipeline and second pipe, filler is set, thermal conductivity between the first pipeline and second pipe is improved, because being brass, makes second pipe, therefore the resistance value of second pipe is also larger, after passing through electric current, the caloric value of second pipe is larger than the first pipeline, and cooling water is mainly passed through in heat radiation, therefore heat on second pipe need to be transmitted on the first pipeline fast, then be transmitted on cooling water and dispel the heat.

In technique scheme, preferably, described filler forms contact tube, the heat sending due to the conduction of second pipe is than many on the first pipeline, and traditional water-cooling terminal second pipe and the first pipeline are only in the just conducting of the solder joint place of brazing, therefore electric current must flow on whole second pipe, make like this loss of electric weight very large, and caloric value is also very large, easy burn-out water-cooling terminal, filler makes the first pipeline directly contact conduction with second pipe after forming contact tube, this makes after the electric current on second pipe access copper bar, electric current can flow directly into the first pipeline, this reduces the caloric value in electric current conductive process, and heating is mainly sent from the first pipeline, and the first pipeline directly contacts with cooling water, this more accelerates heat radiation.

In technique scheme, preferred, the described second pipe end in capacitor outside is provided with bulge loop, arranges while adding filler in the gap of bulge loop for the first pipeline and second pipe convenient.

The utility model compared with prior art, there is following beneficial effect: the utility model arranges filler between the first pipeline and second pipe, thermal conductivity between the first pipeline and second pipe is improved, because being brass, makes second pipe, therefore the resistance value of second pipe is also larger, after passing through electric current, the caloric value of second pipe is larger than the first pipeline, and cooling water is mainly passed through in heat radiation, therefore heat on second pipe need to be transmitted on the first pipeline fast, then be transmitted on cooling water and dispel the heat.
