Abstract
The utility model discloses a kind of grid cushions, and encapsulation type reactor is isolated, including magnet ring, the coil and shell that are wound on the magnet ring, the coil being wound on magnet ring is isolated inside the shell using grid cushion positioning, and the casting glue by being potted in grid cushion grid and casing insulation and heat conduction.The utility model is simple in structure, at low cost, and assembly is simple and convenient.
Description
Technical field
The utility model is related to a kind of grid cushions, and encapsulation type reactor is isolated, for distributed photovoltaic converter system, electronic
In automobile power drive system, belong to reactor meter technical field.
Background technology
Traditional magnetic ring coil encapsulation type reactor is as shown in Figure 1, the surrounding using magnetic ring coil coats insulating paper and magnet ring
The mode and casing insulation of coil bottom packing paper, coil 1 are wound on magnet ring 2, are first encased inside 5 bottom of shell with packing paper 4, then in coil
It is put into shell 5 after 1 surrounding cladding outsourcing insulating paper 3, casting glue 6 is then poured into shell 5.
The magnetic ring coil encapsulation type reactance used in traditional distributed photovoltaic converter system, electric drive system for electric vehicles
Device.In embedding, reached by the way of coating insulating paper and magnetic ring coil bottom packing paper in the surrounding of magnetic ring coil coil with
Casing insulation, since the thermal coefficient of insulating paper is much smaller than the thermal coefficient of casting glue, and insulating paper also adds magnet ring wire
The thermal resistance of heat conduction between circle and shell, influences heat transfer efficiency.System voltage is higher, and insulating requirements are higher, and insulating layer need to be thicker, this
The radiating efficiency for just seriously reducing reactor influences reactor volume and cost, reduces the competitiveness of product in market.
Utility model content
Due to problem of the existing technology, the purpose of this utility model is to propose a kind of grid cushion isolation encapsulation type reactance
Device, when to solve magnetic ring coil embedding inside the shell and insulation and the heat conduction problem of shell.
To achieve the goals above, the utility model proposes a kind of grid cushion be isolated encapsulation type reactor, including magnet ring,
The coil and shell being wound on the magnet ring, the coil being wound on magnet ring are isolated in the shell using grid cushion positioning
It is interior, and the casting glue by being potted in the grid cushion grid and the casing insulation and heat conduction.
Wherein, the grid cushion is foldable molding or open and flat.
Wherein, it is circle when the grid cushion is open and flat.
Wherein, when the grid cushion folds, it is the up big and down small cup-shaped of internal diameter, is close to the outer casing inner wall.
Due to using the technology described above, the grid cushion of the utility model is isolated encapsulation type reactor, and isolation is simple, can
It leans on, makes full use of the good insulation and heat conductivility of casting glue, have superior insulation and heat-conducting effect with shell, without extra insulating paper
(adhesive tape) coats, and solves the problems, such as that insulating paper thermal coefficient is small well and increases radiating efficiency caused by thermal conduction resistance, and
System voltage is higher, increases the thickness of grid cushion, that is, increases influence of the thickness of filling casting glue in grid to heat transfer efficiency
Much smaller than the thickness for increasing insulating paper, grid cushion uses injection molding, is suitble to batch, the inexpensive mode of production, in order to save packet
Transport space is filled, grid cushion is designed to folding open and flat formula, and by outer casing inner wall folding forming, magnetic ring coil is isolated in positioning,
It assembles simple and convenient.

Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Fig. 2, a kind of structural schematic diagram of grid cushion isolation encapsulation type reactor of the utility model, including magnet ring
2, the coil 1 and shell 5 being wound on the magnet ring 2, the coil 1 being wound on magnet ring 2 are isolated in shell 5 using grid cushion positioning
It is interior, and the casting glue 6 by being potted in grid cushion grid insulate with shell 5 and heat conduction.
When installation, shown in Fig. 3, open and flat grid cushion 4 is put into shell 5 (at circle) first, open and flat grid cushion 4 will
The grid cushion 3 that the folding of the up big and down small cup-like shape of internal diameter is folded into along the inner wall of shell 5 is tightly attached on the inner wall of shell 5, then
It is put into the coil 1 being wound on magnet ring 2, the composition of casting glue 6 is then poured into shell 5.
It, can also net as needed in actual use for positioning, isolation in the present embodiment when magnetic ring coil embedding
Lattice pad is applied to positioning, isolation when the coil embedding of other core types.
