Description

A kind of reactor cooling water channel structure
Technical field
The present invention relates to a kind of reactor cooling water channel structure, specifically belong to frequency conversion class power electronic equipment.
Background technology
Reactor heat radiation is the heat radiation emphasis of frequency conversion class power electronic equipment always, and for the power electronics frequency conversion equipment of water-cooling, the reactor heat radiation of its inside becomes a great problem.Electricity separation formula water cooling reactor, cooled plate is adopted to be clipped between iron core and line bag, or the turn-to-turn of coil, carry out heat exchange by the contact-making surface of iron core, wire turn and cooled plate, the heat radiation power that cooled plate internal duct will pass over, is taken away by the cooling fluid in pipeline.In accompanying drawing 1, in conventional reactor cooled plate circuit design, be much in order, from A phase to C phase, the flow path of design cooling fluid, as can be seen from Figure 1, A, B, C triple line bag is according to the order of planar alignment, B phase is middle, and B phase, while self-heating, also will affect by the heating of adjacent A phase and C phase, therefore, from general reactor design experience, the temperature rise of B phase is the highest, and hottest point is just in the place that B phase is adjacent with A, C two phase line bags.Traditional air-cooled reactor, due to air channel, B phase is unavoidably the highest, and therefore, the temperature rise of B phase determines the temperature rise of reactor, and when the temperature rise of B phase line bag reaches capacity time, the line bag of A, C two-phase also has a segment distance from the limit.Cause certain waste like this.
Summary of the invention
Invention provides a kind of reactor cooling water channel structure, its object is to solve the problems of the technologies described above, and provide a kind of and the temperature rise of A, B, C phase line bag of reactor can be made more even, instead of the temperature rise of B phase line bag is higher than other two-phases.
Technical scheme of the present invention: a kind of reactor cooling water channel structure, comprise A, B, C phase cooled plate, connecting line between three pole reactor coil and cooled plate, described the design of intake is at the water inlet of B phase cooled plate, and cooling fluid first through B phase line bag, then passes through other two phase lines bags successively.
Described cooling fluid first through B phase line bag, more successively through C, A phase line bag.
Described cooling fluid first through B phase line bag, more successively through A, C phase line bag.
The invention has the advantages that: the present invention does not change mode of manufacturing and the operation of water cooling reactor, only need to redesign when connection cooled plate pipeline, by the water inlet that the design of intake is B phase cooled plate, cooling fluid is first through B phase line bag, pass through other two phase lines bags again, after heat exchange, reserve reactor water-cooling system.
Accompanying drawing explanation
Fig. 1 is the design principle figure in reactor water route in prior art.
Fig. 2 is reactor water route design principle figure of the present invention.
Embodiment
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As Fig. 1, in accompanying drawing 1, in conventional reactor cooled plate circuit design, much in order, from A phase to C phase, the flow path of design cooling fluid, as can be seen from Figure 1, A, B, C triple line bag is according to the order of planar alignment, and B phase is middle, B phase is while self-heating, also to affect by the heating of adjacent A phase and C phase, therefore, from general reactor design experience, the temperature rise of B phase is the highest, and hottest point is just in the place that B phase is adjacent with A, C two phase line bags.Traditional air-cooled reactor, due to air channel, B phase is unavoidably the highest, and therefore, the temperature rise of B phase determines the temperature rise of reactor, and when the temperature rise of B phase line bag reaches capacity time, the line bag of A, C two-phase also has a segment distance from the limit.Cause certain waste like this.
As Fig. 2, a kind of reactor cooling water channel structure, comprise A, B, C phase cooled plate, connecting line between three pole reactor coil and cooled plate, described the design of intake is at the water inlet of B phase cooled plate, described cooling fluid first through B phase line bag, more successively through C, A phase line bag.
In like manner, described cooling fluid, also can successively through A, C phase line bag first through B phase line bag.
Advantage of the present invention: for water cooling reactor, the coolant temperature of import department is minimum, the increase in the path flow through along with cooling fluid, and the temperature of cooling fluid rises gradually.If the import of cooling fluid is just designed near B phase line bag, the coolant temperature then entering B phase line bag cooled plate is minimum, the heating power of B phase line bag is conducive to be taken away to greatest extent, and then through A, C phase line bag, because the heat radiation of A, C phase line bag all can not be subject to the impact of other line bags heating in both sides, the suitable raising of coolant temperature can not have influence on the heat radiation of himself.Like this, the hottest B phase line bag is subject to the cooling of cooling fluid at first, then radiating condition A phase and C phase line bag relatively has preferably been arrived, although the rising of coolant temperature bring a little decline of radiating efficiency, carry out rational flow design, the temperature rise of A, C phase line bag also can control in the reasonable scope.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
