Description

A kind of inside conductive structure of inverter

Technical field

The utility model relates to a kind of inside conductive structures of inverter.

Background technique

Inverter uses cast aluminium cabinet at present, and the element of heat can be generated by being equipped with IGBT module etc. in cabinet, also referred to as The heat source body is directly installed on the cast aluminium cabinet containing radiator by heat source body.The problem is that: the heat that heat source body generates It is gathered in around heat source body on radiator for a long time, the X of heat source body and cast aluminium cabinet contact surface, Y-direction thermal conductivity are 96W/ (mK), thermally conductive relatively slow, so that heat source body is constantly in the condition of high temperature, influences the use of inverter, and the shadow to inverter performance It rings, or even reduces the service life of inverter, inverter can be directly damaged when serious.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of inside conductive structures of inverter, improve heat dissipation Effect.

The technical issues of the utility model, is solved by following technical proposals: a kind of inside conductive structure of inverter, packet The cast aluminium cabinet containing radiator is included, feature is to install graphite heat-conducting fin between cast aluminium cabinet and heat source body.Load onto graphite heat conducting After piece, X, Y-direction thermal conductivity are 1000-2000W/(mK).The heat of heat source body generation in this way, can disperse rapidly around It goes out, to reach heat dissipation effect rapidly and efficiently.

Heat source body is mounted in graphite heat conducting on piece by the utility model, and heat-transfer rate is fast, hot concentration will not be generated, to existing casting The other structures of aluminium cabinet are not required to change.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is the utility model decomposition texture schematic diagram；

Figure label explanation:

1 --- heat source body；

2 --- graphite flake；

3 --- cast aluminium cabinet.

Specific embodiment

As shown in Fig. 1 utility model structural schematic diagram and Fig. 2 utility model decomposition texture schematic diagram, a kind of inverter it is interior Portion's conductive structure installs graphite heat-conducting fin between cast aluminium cabinet 3 and heat source body 1 including the cast aluminium cabinet 3 containing radiator.

The graphite heat-conducting fin of the utility model is exactly graphite flake 2.

Such as without graphite heat-conducting fin, X, Y-direction thermal conductivity are 96W/mK.After loading onto graphite heat-conducting fin, X, Y-direction are thermally conductive Rate is 1000-2000W/mK, and the thermal conductivity of Z-direction is 10 W/mK.The heat of heat source body generation in this way, can rapidly around Dispersion is gone out, to reach heat dissipation effect rapidly and efficiently.
