Because the pumping of this type is constructed at present, employed frequency converter 63 is when installing and fixing, must be provided with one and be tabular base 60, its top is provided with a pole 61 in addition, and being provided with one on pole 61 tops can be for the casing 62 of frequency converter 63 accommodation spaces, to reach the installation of setting up of this frequency converter 63, so, the shared space of whole pumping structure must comprise the pumping 50 of position arranged side by side on base plate 60 and casing 62 that can ccontaining frequency converter 63, therefore, one sizable installing space must be arranged, begin to be installed and the shortcoming that can't give miniaturization exists.

The utility model content

The motor of a kind of tool converter plant that the utility model provides can reach the radiating airflow that directly converter plant is installed in the motor top and cooperates the motor fan inside to be produced and be lowered the temperature, and can reduce required installing space.

For realizing aforementioned purpose, the technological means that the utility model used is the motor that is to provide a kind of tool converter plant, wherein the shell place of motor body is provided with accommodation chamber, its in-line power road plate is ccontaining and be provided with outer cover in outside mask, be respectively equipped with the radiating seat and the heating panel that can recline and carry out heat conduction mutually between the inside of aforementioned accommodation chamber and circuit board, other puts with respect to the hot seat of heat in the outside of accommodation chamber and is formed with several fin.

The motor of described tool converter plant, wherein accommodation chamber is provided with top flat and number spacer towards motor body one side, and spacer can be fixed on the tab of institute's shape on the body.

The motor of described tool converter plant, but wherein spacer and tab be respectively equipped with fixing hole and location hole and between the two attachment screw combined fixing.

The motor of described tool converter plant, wherein the accommodation chamber internal styling cooperates the board design that is provided with electronic component.

The motor of described tool converter plant, wherein housing opening cooperates the shell moulding to be formed with breach.

Embodiment

For making the constructing apparatus that further specifies this case, and other creation purpose and effect, below enumerate a specific embodiment now, and conjunction with figs. is described in detail as follows: a graphic part:

Referring to Figure 1 and Figure 2, the motor of the designed tool converter plant of the utility model, wherein motor body 10 is provided with the mechanism that draws water in an end, and the below is formed with a base 11 that can combine with the placement, be formed with the tab 120 that some intervals form on the shell 12 of body 10, and in its in addition end be arranged with an end cap 13, between the tab 120 at aforementioned interval and end cap 13, be formed with through hole 14, and the end of end cap 13 is provided with a plurality of pores 131, so, motor is after startup and fan inside action, cool exterior air can be sucked by the pore 131 of end cap 13 and send by through hole 14 again, and blow to shell 12 directions and carry out cooling effect with the shell 12 that reaches body 10.

Body 10 tops are provided with an accommodation chamber 20 again, this accommodation chamber 20 is provided with several spacers 22 and a top flat 24 in the bottom with respect to tab 120, each spacer 22 mutually combines fixing with the tab 120 of shell 12, its fixed form is fixed on the location hole 121 of tab 120 after can screw running through the set fixing hole 221 of spacer 22, and top flat 24 can be replaced on shell 12;

Accommodation chamber 20 is an opening towards last and make with transcalent material again, for example: aluminum alloy materials, accommodation chamber 20 inside are formed with a smooth radiating seat 21, and the inner space can cooperate circuit board 30 exterior design and can be installed on inside for it, is formed with the outstanding fin 23 of number in the outside of accommodation chamber 20 and with respect to radiating seat 21 positions in addition.

Aforementioned circuit plate 30 is provided with the part that frequency changer circuit and electronic component can produce high heat and then is connected with a heating panel 31, when circuit board 30 is assembled in accommodation chamber 20 inside, its heating panel 31 directly closely abuts on the radiating seat 21 and (cooperates referring to shown in Figure 3), so, the heat that electronic component produced can conduct to the housing and fin 23 places thereof of accommodation chamber 20 via heating panel 31 and radiating seat 21.Covering 40 in addition is a hollow cover body, is formed with respectively linearly or the breach 41 of arc in its opening and with respect to two sides of shell 12, and it can directly be nested with and abut in accommodation chamber 20 tops, to reach the proofing dust and protecting effect.

Because the motor of the tool converter plant that the utility model is designed, the wherein inner accommodation chamber 20 that circuit board 30 is installed is to be directly installed on the shell 12, and the air-flow that motor is produced in the action back is except can blowing to shell 12 surfaces, also can blow to accommodation chamber 20 and fin 23 places thereof, therefore, can be under the situation of the design that does not need to install separately fan, the heat that circuit board 30 is produced conducts to accommodation chamber 20 shells and fin 23 places effectively lower the temperature; Again because accommodation chamber 20 is to be set directly at body 10 tops, is about to required frequency conversion control circuit and directly so, also can significantly reduces overall volume and can reduce required occupation space is set at this place in the position.
