Technical field
The utility model relates to a kind of DC-DC switch technology, specially refers to a kind of DC-DC converter.
Background technology
Along with scientific and technical fast development, DC-DC switch technology is widely used in various fields, and, from low-power applications field, progressively turn to high-power applications field. So-called DC-DC conversion is in fact direct current transformation, converts in the situation that not affecting use power by galvanic voltage. Conventionally, adopt the mode of DC-AC-direct current to realize DC-DC conversion, by direct current be converted to alternating current (as, the direct current of 12V is converted to 12V alternating current), device by transformer one class change alternating current voltage (as, the alternating current of 12V is converted to the alternating current of 36V), then by alternating current be converted to direct current (as, the alternating current of 36V is converted to the direct current of 36V), thus realize galvanic transformation. In this type of DC-DC converter, conventionally to use electronic devices such as FET, transformer and inductor, because this electron-like device is all worked under larger curtage condition, its device itself all can produce larger heat. But the operating temperature of electronic device all has restriction conventionally, exceeding its service behaviour of limiting temperature or efficiency will reduce greatly, and what have even also can be burnt. Although, adopt class cooling provisions such as strengthening fin area or forced ventilation can reduce the operating temperature of this type of electronic device, but still can not ensure its reliability and stability. In order to ensure the reliability and stability of DC-DC converter, adopting on the basis of various cooling provisions, also adopt and use below far below rated power or the mode such as multiple device parallel connections, thereby greatly increased complexity and the cost of manufacture of line construction. The problems such as obviously, it is poor that prior art DC-DC converter exists reliability and stability, and line construction complexity and cost of manufacture are higher.
Summary of the invention
For solving the problems such as the reliability and stability of prior art DC-DC converter existence are poor, and line construction complexity and cost of manufacture are higher, the utility model proposes a kind of DC-DC converter. The utility model DC-DC converter, comprises printed substrate, interior heat dissipation tank, outer heat dissipation tank, insulation grease and cooling fluid; The printed substrate interval that electronic device is installed is fixed on interior heat dissipation tank bottom, and interior heat dissipation tank is enclosed construction and is filled with insulation grease therein; Outer heat dissipation tank is sleeved on outside interior heat dissipation tank, between interior heat dissipation tank and outer heat dissipation tank, is filled with cooling fluid; Wherein, described interior heat dissipation tank is provided with circulation cooling mechanism or the rabbling mechanism of insulation grease; Described circulation cooling mechanism comprises circulation line, circulating pump and heat exchanger; Described rabbling mechanism comprises stirring motor and stirring vane.

Detailed description of the invention
Accompanying drawing 1 is the structural representation of facing of the utility model DC-DC converter embodiment 1, accompanying drawing 2 is plan structure schematic diagrames of the utility model DC-DC converter embodiment 1, in figure, 1 is interior heat dissipation tank, 2 is outer heat dissipation tank, and 3 is printed substrate, and 41 is circulation line, 42 is circulating pump, and 43 is heat exchanger. As seen from the figure, the utility model DC-DC converter, comprises printed substrate 3, interior heat dissipation tank 1, outer heat dissipation tank 2, insulation grease and cooling fluid; Printed substrate 3 intervals that electronic device is installed are fixed on interior heat dissipation tank 1 bottom, and interior heat dissipation tank 1 is for enclosed construction and be filled with insulation grease therein; Outer heat dissipation tank 2 is sleeved on outside interior heat dissipation tank 1, between interior heat dissipation tank 1 and outer heat dissipation tank 2, is filled with cooling fluid. The utility model DC-DC converter is immersed in the printed wire slab integral that electronic device is installed in insulation grease, in the time that electronic device produces heat, may cause localized hyperthermia, the grease that makes to insulate gasification, not only consume amount of heat, also made gas or the heated high-temperature insulation grease of heat with gasification formation, be climbed to the top of interior heat dissipation tank from the bottom of interior heat dissipation tank, the heat that electronic device is produced is distributed rapidly, has higher radiating efficiency. Because interior heat dissipation tank is sleeved in outer heat dissipation tank, and, between interior heat dissipation tank and outer heat dissipation tank, fill cooling fluid, the interior heat dissipation tank liquid that is cooled is cooling in time, make the temperature of printed substrate remain on lower level, can give full play to its service behaviour, and effectively improve reliability and stability.
The grease with insulating property (properties) all can be used as insulation grease of the present utility model, comprises transformer oil or diesel oil; The liquid with cooling property all can be used as cooling fluid of the present utility model, comprises water or anti-icing fluid.
For further improving radiating effect, circulation cooling mechanism (as shown in Figure 2) or the rabbling mechanism of insulation grease can be set at described interior heat dissipation tank; Described circulation cooling mechanism comprises circulation line, circulating pump and heat exchanger; Described rabbling mechanism comprises stirring motor and stirring vane.
For convenience of transport and use, described outer heat dissipation tank can be enclosed construction. But for safety, need heat dissipation tank top outside that safety valve is set. While making pressure in outer heat dissipation tank exceed setting value, automatically open, ensure safety.
Obviously, the useful technique effect of the utility model DC-DC converter is the operating temperature that can effectively reduce electronic device, can give full play to its service behaviour, and effectively improves reliability and stability. And, simple in structure, easy to use.
