Abstract
The utility model discloses a miniature inverter casing and a miniature inverter, and relates to the technical field of structure design. At least one concave embossment is arranged at the bottom of the inner wall of the miniature inverter casing. The miniature inverter comprises a circuit board and the miniature inverter casing. The circuit board is fixed at the bottom of the inner wall of the miniature inverter casing. The embossment on the miniature inverter casing is opposite to the circuit board. A heat conduction layer with predetermined thickness is arranged between the embossment and the circuit board. According to the utility model, the shape of the miniature inverter casing is changed; a radiating fin in the prior art is cancelled; heat generated by the circuit board is directly transmitted to the miniature inverter casing and then is discharged out of the casing in a heat conduction mode; and on the premise that the miniature inverter has a good radiating effect and invariable volume, the cost is saved.
Description
Technical field
The utility model relates to the structure-design technique field, particularly a kind of miniature inverter shell and miniature inverter.
Background technology
Inverter is a kind of electric power adjusting device of being made up of semiconductor device, is mainly used in direct current power is converted to alternating electromotive force.Generally constituted by boost loop and inversion bridge type return.The loop of boosting boosts to the required direct voltage of inverter output control to the direct voltage of solar modules; The inversion bridge type return then converts the direct voltage after boosting to the alternating voltage of conventional frequency of equal valuely.The common volume of comparatively traditional inverter is big and be located at indoor, the mode that the solar modules employing is connected in series and traditional inverter join, but in case traditional inverter goes wrong, then can lose whole electric energy, therefore, adopt the miniature inverter identical with the solar modules number at present, miniature inverter is located at outdoor and is connected with each solar modules respectively more, pass between each solar modules is the mode that is connected in parallel, and has effectively reduced the electric energy of loss.
And because miniature inverter need be located at outdoor, for guaranteeing the circuit board energy operate as normal in the miniature inverter, miniature inverter will have stronger heat sinking function, and miniature inverter of the prior art adopts radiating mode as shown in Figure 1, circuit board 102 is fixed in the bottom of described miniature inverter shell 101, be provided with thermal grease 103 between described circuit board 102 and the fin 104, described fin is provided with fan 105, when this radiating mode need improve heat-sinking capability, the power that needs to strengthen the area of fin 104 or improve fan 105 causes cost to increase.
The utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is: how guaranteeing to save cost under the good and constant big prerequisite of small product size of radiating effect.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of miniature inverter shell, and the bottom of described miniature inverter outer casing inner wall is provided with the projection of at least one inner concavity.
The invention also discloses a kind of miniature inverter, described miniature inverter comprises: circuit board and described miniature inverter shell, described circuit board is fixed in the bottom of described miniature inverter outer casing inner wall, projection on the described miniature inverter shell is relative with described circuit board, is provided with the heat-conducting layer of preset thickness between described projection and the described circuit board.
Wherein, described preset thickness is 0.5mm ~ 8.0mm.
Wherein, the top of described miniature inverter outer casing inner wall is provided with fan, and the air outlet of described fan is relative with described circuit board.
Wherein, described heat-conducting layer is thermal grease.
(3) beneficial effect
The utility model is by changing the shape of miniature inverter shell, cancelled fin of the prior art, the heat that circuit board is produced directly transfers to miniature inverter shell, heat is discharged from outside the shell with heat exchange pattern then, provide cost savings under the prerequisite that miniature inverter radiating effect is good and constancy of volume is big guaranteeing.

Fig. 2 is the structural representation according to the miniature inverter of a kind of execution mode of the utility model.
Wherein, 101: miniature inverter shell; 102: circuit board; 103: thermal grease; 104: fin; 105: fan; 106: hot-air; 201: miniature inverter shell; 202: circuit board; 203: heat-conducting layer; 204: fan; 205: hot-air; 206: projection.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Fig. 2 is the structural representation according to the miniature inverter of a kind of execution mode of the utility model; With reference to Fig. 2, described miniature inverter comprises: miniature inverter shell 201 and circuit board 202, described circuit board 202 is fixed in the bottom of described miniature inverter shell 201 inwalls, the bottom of described miniature inverter shell 201 is provided with the projection 206 of at least one inner concavity, described protruding 206 is relative with described circuit board 202, described protruding 206 and described circuit board 202 between be provided with the heat-conducting layer 203 of preset thickness.
For guaranteeing heat-conducting effect, preferably, described preset thickness is 0.5mm ~ 8.0mm.
Be to strengthen heat-sinking capability, preferably, the top of described miniature inverter shell 201 inwalls is provided with fan 204, and the air outlet of described fan 204 is relative with described circuit board 202.
Preferably, described heat-conducting layer 203 is thermal grease.
The utility model has been cancelled fin of the prior art by changing the shape of shell, and the heat that circuit board is produced directly transfers to miniature inverter shell, and heat is discharged from outside the shell with heat exchange pattern then.Under the prerequisite that radiating effect is good and constancy of volume is big that guarantees miniature inverter, provide cost savings (having reduced by a radiator).
Above execution mode only is used for explanation the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
