Description
Technical field
the present invention relates to a kind of novel resistance board.
Background technology
generally in power-supply device, need electric energy conversion to become thermal energy consumption to fall, be mostly to use resistance device, make it pass through certain electric current, consume the electric energy of corresponding energy.And the resistance that generally power is larger is commonly called as cement resistor, because resistive element puts into porcelain frame, with special noninflammability thermal cement filling sealing, cause its heat-sinking capability poor.Structural volume is comparatively large, and the general length of the resistance needed for consumption electric energy and the diameter dimension that exceed multikilowatt are all larger, is not only not easy to install application on tight type equipment, and cost is larger.
Summary of the invention
for the technical deficiency of above-mentioned existence, the object of this invention is to provide a kind of novel resistance board.
for solving the problems of the technologies described above, the present invention adopts following technical scheme:
a kind of Novel resistance plate, comprise aluminium sheet, fastening be arranged on the relative dual-side of described aluminium sheet at least one insulating part each, insulated by the insulating part described in these resistance wire be around on described aluminium sheet.
preferably, described aluminium sheet is the two blocks of aluminium sheets paralleling setting, and the cross section of described insulating part is E type, is clamped in the relative two edges of the aluminium sheet described in two pieces with two of its E type oral area correspondences.
preferably, described insulating part is equidistantly be arranged in each plural insulating part of described aluminium sheet relative to dual-side along on the edge length direction of the aluminium sheet at its place.
preferably, described insulating part is the insulating part of each one of the relative dual-side that length is equal with the length at the edge of the aluminium sheet at its place.
preferably, the insulating part described in this offers the ventilation hole that the space between the aluminium sheet described in two pieces connects.
preferably, described ventilation hole be a rectangular through-hole going up along its length or along its length on multiple small through hole of being equally spaced.
preferably, described aluminium sheet offers multiple thermal vias.
preferably, described aluminium sheet is one block of aluminium sheet offering multiple thermal vias, and described insulating part is the U-shaped insulating part of two cross sections, is clamped in the relative both sides of the edge of described aluminium sheet respectively with its peristome.
preferably, the ring bodies being convenient to wiring is formed at the two ends of described resistance wire respectively.
beneficial effect of the present invention is: adopt the aluminium sheet with thermal vias, at the relative side of aluminium sheet, insulating part is set, resistance wire is around on aluminium sheet by insulating part insulation and forms resistance board, this resistance board ventilation and heat performance is good, structure is simple, small and exquisite, easily be installed in the cabinet of tight structure, and production cost is lower.

Embodiment
below in conjunction with embodiment shown in the drawings, the present invention is described in detail below:
as shown in accompanying drawing 1 and accompanying drawing 2, resistance board of the present invention comprise aluminium sheet 1, fastening be arranged on the relative dual-side of described aluminium sheet 1 at least one insulating part 2 each, insulated by the insulating part 2 described in these resistance wire 3 be around on described aluminium sheet 1, and the ring bodies 5 being convenient to wiring is formed respectively at the both ends of resistance wire 3, particularly, aluminium sheet 1 offers thermal vias 4, can dispel the heat in time, well when working.
embodiment one: as accompanying drawing 3, shown in 5 and 6, resistance board comprises two blocks of aluminium sheets 1 and two insulating parts 2, each aluminium sheet 1 all offers thermal vias 4, the cross section of two insulating parts 2 is all in E type, with two oral area difference corresponding clip tightly in the relative two edges of two aluminium sheets 1, and on insulating part 2, offer the ventilation hole of being convenient to further dispel the heat, its structure can be the rectangular through-hole 6 gone up along its length, also can be the multiple small through hole 7 going up equidistant arrangement along its length, but ensure that the width of these small through hole 7 is less than the width of insulating part 2 itself, this ventilation hole all can and two blocks of aluminium sheets 1 between gap between connect, so that the timely heat radiation of resistance board in the course of work, resistance wire 3 is around on aluminium sheet 1 by the insulation of these insulating parts 2, due to the width of insulating part 2, can ensure that resistance wire 3 does not contact with aluminium sheet 1, thus ensure insulation, certainly, for the situation of two blocks of aluminium sheets 1, insulating part 2 also can adopt the form of the multiple less insulating part 2 be equally spaced in every side, the production technology of such insulating part 2 is also simpler, and between adjacent insulating part 2, naturally just define the air holes of being convenient to dispel the heat.
embodiment two: as shown in Figure 4, resistance board comprises one block of aluminium sheet 1 and two insulating parts 2, the cross section of two insulating parts 2 is U-shaped respectively, it is clamped in the edge, two opposite sides of aluminium sheet 1 respectively with oral area correspondence, same aluminium sheet 1 offers thermal vias 4, resistance wire 3 is around on aluminium sheet 1 by insulating part 2 insulation of both sides, like this due to insulating part 2 have on aluminium sheet 1 for width, resistance wire 3 would not be made to contact with aluminium sheet 1, and then ensure insulation, same, insulating part 2 also can adopt each multiple form in both sides, to make to form heat dissipation channel between adjacent insulating part 2, be more conducive to heat radiation.
novel resistance board provided by the invention, aluminium sheet is offered multiple thermal vias, one that is with ventilation hole or the multiple form be equally spaced are adopted for insulating part, the final radiating effect effectively improving whole resistance board, structure is simple, small and exquisite, easily be installed in the cabinet of tight structure, and production cost is lower.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to the present invention's spirit change or modify, and all should be encompassed within protection scope of the present invention.
