Abstract
The utility model relates to a power supply inverter, which comprises a housing (11), wherein the inner part of the housing (11) also comprises a first circuit board (12), a second circuit board (13), a first radiator (14) and a second radiator (15), wherein the first radiator (14) and the first circuit board (12) are fixedly connected and are fixed in the housing (11), and the second radiator (15) and the second circuit board (13) are fixedly connected and are fixed in the housing (11). The utility model has the advantages that a state that two radiators are overlapped top and bottom is formed, the length of the radiator is effectively shortened, a wind channel is formed, heat dissipation is profited, the length is reduced and production cost is saved.
Description
Technical field
The utility model relates to a kind of power inverter, relates in particular to the fixed form of radiator and wiring board in a kind of power supply on vehicle inverter.
Background technology
Motherboard in the power inverter mostly is integral type greatly at present, and just wiring board is that one is connected with radiator, sees Fig. 1: the wiring board 2 and the radiator 3 of monoblock is fixed together and is placed in housing interior 1; Such connected mode can cause two problems in the high power contravariant device: the first, because wiring board and radiator are bigger, cause that housing is also big; The second, can not form good air channel, to reach the effect of heat radiation; Both enabled to accomplish to dispel the heat completely, cost is improved, for manufacturer, just do not reached profit margin.
Summary of the invention
The utility model technical issues that need to address have provided a kind of not only small and exquisite but also good power inverter that dispels the heat, and are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises housing; In housing, also comprise first wiring board, second wiring board, first radiator and second radiator; Described first radiator is fixedlyed connected with first wiring board, and with the housing internal fixation; Described second radiator is fixedlyed connected with second wiring board, and with the housing internal fixation; Between described first radiator and first wiring board and second radiator and second wiring board is parallel.
Compared with prior art, the beneficial effects of the utility model are: form two radiators overlapping situation up and down, effectively shortened the length of radiator, formed better air channel, be more conducive to heat radiation; Dwindle length, also saved production cost.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises housing 11; In housing 11, also comprise first wiring board 12, the second wiring boards, 13, the first radiators 14 and second radiator 15; Described first radiator 14 is fixedlyed connected with first wiring board 12, and with housing 11 internal fixation; Described second radiator 15 is fixedlyed connected with second wiring board 13, and with housing 11 internal fixation;
Described first radiator 14 and second radiator 15 fixedly connected with first wiring board 12 is connected with nut by screw with second wiring board 13 is fixedly connected;
Between described first radiator 14 and first wiring board 12 and second radiator 15 and second wiring board 13 is parallel.
The utility model is that motherboard is divided into two: first wiring board, and second wiring board is fixed together first wiring board and first radiator with screw, insert then in the groove of housing, does the location with the screw hole of housing both sides with screw; Second wiring board and second radiator are fixed together with screw, insert then in the beneath groove of housing, do the location with screw.Like this, form two radiators overlapping situation up and down, effectively shortened the length of radiator, formed better air channel, be more conducive to heat radiation.
