Abstract
The utility model discloses a box used to install electrical apparatus control circuit board, which is composed of a heat radiation plate and a box cover, the box cover is connected with the heat radiation plate through a screw, the bottom surface of the heat radiation plate is disposed with heat radiation fins. The box of the utility model uses a structure of two ends open type, and the bottom surface is designed as the structure of heat radiation plate, then the utility model can form a natural wind tunnel structure form when being used, due to the flow of natural wind, not only the electrical apparatus control circuit board and electronic components installed within the box can get very good effect of heat radiation and cooling, but also the dust is uneasy to adhere to the electrical apparatus control circuit board. Therefore, the utility model has advantages of dustproof and good heat radiation effect, and has the advantages of simple structure, easy manufacture and convenient installation and maintenance of the electrical apparatus control circuit board as well.
Description
Technical field:
The utility model and a kind of box body that is used to install the electrical apparatus control circuit plate belong to electrical apparatus control circuit plate mounting box technical field.
Background technology:
At present, electrical apparatus control circuit plate mounting box in the prior art adopts the box body of enclosed construction mostly, promptly generally adopt the electrical apparatus control circuit plate is installed in the box body of sealed type, though the box body of this sealed construction has the advantage of good dustproof effect, but exist the shortcoming of weak heat-dissipating, be easy to make the electronic component heating on the electrical apparatus control circuit plate, particularly make the great-power electronic element heating of electrical apparatus control circuit plate easily, thereby cause the electronic component of electrical apparatus control circuit plate to damage.Therefore the existing result of use that is used to install the box body of electrical apparatus control circuit plate still is not ideal enough.
Summary of the invention:
The purpose of this utility model is: the box body that is used to install the electrical apparatus control circuit plate that provide a kind of and can prevent dust, radiating effect is good again, and to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it is made up of heating panel 1 and box cover 2, and box cover 2 is connected with heating panel 1 by screw 3, is provided with fin 4 in the bottom surface of heating panel 1.
The power electronic element 7 of electrical apparatus control circuit is installed on the surface of heating panel 1.
On heating panel 1, be connected with the electrical apparatus control circuit plate 10 that electronic component 9 is installed by screw rod 8.
Owing to adopted technique scheme, box body of the present utility model adopts open at both ends formula structure, and its bottom surface is designed to the structure of heating panel, so in use, the utility model has just formed the construction of wind tunnel form of a nature, because flowing of natural wind not only makes the electrical apparatus control circuit plate and the electronic component thereof that are installed in the box body well be dispelled the heat and to lower the temperature, and can also make dust be difficult for sticking on the electrical apparatus control circuit plate.Therefore, the utility model compared with prior art, the utility model not only has and can prevent dust and the advantage of good heat dissipation effect, but also have simple in structure, make easily and install and maintenance electrical apparatus control circuit plate advantage easily all.The utility model is particularly suitable for the thyristor dc motor speed control device.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
The schematic diagram that accompanying drawing 2 is a monolithic construction for box cover of the present utility model.
Embodiment:
Embodiment of the present utility model: heating panel 1 preferably adopts the reasonable metal material of heat radiation to make, as adopt aluminium or aluminum alloy materials to make, in order to make heating panel reach better radiating effect, during making, can produce fin 4 simultaneously in the bottom surface of heating panel 1; And box cover 2 can be connected on the heating panel 1 by screw 3; When making box cover 2, box cover 2 can be made into the monolithic construction (as shown in Figure 2) that is provided with side plate on its rectangular panel both sides and does not have baffle plate on the other both sides of rectangular panel; But in order to keep in repair, box cover 2 can be made into by two blocks of side plates 5 and a panel 6 and to form, two blocks of side plates 5 are connected with heating panel 1 by screw 3 respectively, panel 6 is connected with side plate 5 by screw 11 with easier for installation; When the electrical apparatus control circuit plate is installed, the large power, electrically sub-element 7 of its electrical apparatus control circuit plate can be installed on the surface of heating panel 1, so help heat radiation and cooling to large power, electrically sub-element 7 more, the electrical apparatus control circuit plate 10 that electronic component 9 will be installed then is connected on the heating panel 1 by screw rod 8.
