Description
Technical Field
The utility model belongs to the technical field of water pump controller, a external variable frequency control box of water pump is related to.
Background
Currently, the mainstream power factor correction technology is mainly classified into a passive correction technology and an active correction technology. The passive power factor correction technology is to filter partial order harmonic waves by using a network consisting of passive devices such as an inductor, a capacitor, a power diode and the like; the active power factor correction technology adds a first-stage power conversion structure between a rectifying circuit and a load through a switching device, so that the phase of input current tracks the phase of input voltage. The passive PFC circuit has the advantages of being simple, low in cost, good in reliability, but large in size, a user can be allocated in a certain occasion, a passive PFC technology is introduced into a water pump to obtain better cost performance, for certain types of water pumps, the control box is arranged outside the pump body, in order to increase a PFC reactor in the control box, the heat dissipation performance of the control box is limited in the traditional structure, the installation of the PFC reactor is not facilitated, the structure of the control box needs to be improved, and due to the characteristic that the reactor is easy to generate heat during operation, the heat dissipation problem of the control box and the reasonability of the arrangement of the reactor and the control board need to be considered in the design of the control box.
Disclosure of Invention
The utility model aims at the above-mentioned problem that exists among the prior art, provide one kind and be convenient for install the reactor inside and the external variable frequency control box of water pump that heat dispersion is good.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides an external variable frequency control box of water pump, includes the box and installs the reactor in the box, its characterized in that, the box in be provided with rather than the installation step of formula structure as an organic whole, the central undercut of installation step forms the arc wall, the appearance of reactor is placed in the arc wall for cylinder structure and cooperation, the top of installation step is provided with the heat dissipation lid, the structure of heat dissipation lid mutually supports with the reactor and wears to establish the screw and fasten the reactor between heat dissipation lid both sides and installation step, control panel and control panel inwards make its installation form case lid are installed at the top of box, one side of box is seted up fan groove and is installed the fan, and the opposite side of box has the netted vent that corresponds with the fan groove.
The external variable frequency control box of this water pump's technical effect does: increase one in the control box and mutually support installation step and heat dissipation lid with the reactor structure, make the reactor be fixed in its thermal transmission of being convenient for in the box, increase the inside and outside air velocity of box through the installation fan to the control panel is located the inside installation of box top, prevents that it from forming between fan and reactor and blockking, more is favorable to the heat dissipation of control panel.
In the external variable frequency control box of water pump, the heat dissipation teeth are arranged below the mounting step and on the heat dissipation cover in a uniform manner.
In the external variable frequency control box of the water pump, the bottom surface of the mounting step is positioned outside the box body by a cavity type structure below the mounting step on the box body.
The overall heat dissipation performance of the box body is further increased through the design of the heat dissipation teeth.
In the external variable frequency control box of the water pump, the box body and the heat dissipation cover are both aluminum profiles.
Compared with the prior art, this external variable frequency control box utensil of water pump has increased the inside air mobility of box through setting up the control panel in the box top, and the reactor of being convenient for is installed and has been solved the reactor and generate heat the influence to the control box in the box, has further increased the thermal diffusivity of control box through fan and heat dissipation tooth and has made its operation more stable.
