Description

Technical Field

[0001] The utility model relates to the technical field of a water pump control box, in particular to a water pump control box with a heat dissipation mechanism. Background Art

[0002] The water pump control box is suitable for the direct start and stop of the AC380V water pump motor and can protect the motor from overload and phase loss, and manually / automatically realize water supply and drainage of the pool. At present, most of the existing dual water pump control boxes are equipped with a heat dissipation mechanism composed of a drive member and fan blades or a separate fan. Although it can ensure the cooling of internal components, the above-mentioned heat dissipation mechanism needs to be provided with a through hole on the dual water pump control box to ensure stable conduction of airflow. However, the existing through hole is not provided with a corresponding protective structure, which makes it easy for external impurities to contact the heat dissipation mechanism and the internal components of the box through the through hole when the heat dissipation mechanism is not in use, causing a short circuit of the components or damage to the heat dissipation mechanism, thereby reducing the use effect of the dual water pump control box.

[0003] For example, Chinese patent announcement No. CN215188062U discloses a dual water pump control box with a heat dissipation mechanism. When in use, the baffle is pulled downward until the moving contact on the convex strip is combined with the static contact on the inner surface wall of the box. At this time, the driving member is energized to drive the fan blades to rotate, and the baffle is separated from the supporting net to ensure the stable circulation of the airflow, thereby ensuring the heat dissipation efficiency of the inner cavity of the box. Similarly, the baffle is pulled upward to separate the moving contact from the static contact, the driving member stops running, and the baffle is completely covered on the outside of the supporting net. The baffle is stabilized by combining the fastening rod with the mounting plate and the screw holes at the corresponding positions of the box, thereby ensuring the heat dissipation effect while avoiding impurities from entering the box when it is not in use, thereby improving the use effect of the dual water pump control box.

[0004] However, the dual water pump control box with a heat dissipation mechanism in the above application has an overall temperature rise when encountering hot weather. The water pump control box is only cooled by a fan, and the heat dissipation efficiency is low. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a water pump control box with a heat dissipation mechanism. Utility Model Content

[0006] The purpose of the utility model is to provide a water pump control box with a heat dissipation mechanism to solve the problem that the dual water pump control box with a heat dissipation mechanism proposed in the above background technology has a low heat dissipation efficiency because the overall temperature rises when encountering hot weather and the water pump control box is only cooled by a fan.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water pump control box with a heat dissipation mechanism, comprising a water pump control box and a box door, wherein the box door is hinged to the front side of the water pump control box, and a water cooling heat dissipation device is arranged inside the water pump control box.

[0008] The water-cooling heat dissipation device comprises a heat dissipation unit and a fire extinguishing unit.

[0009] The heat dissipation unit includes a liquid storage tank, a thermal conductive back plate, a water pump, and a heat dissipation component. The liquid storage tank is installed at the inner rear end of the water pump control box, the thermal conductive back plate is fixedly connected to the top front end of the liquid storage tank, the water pump is installed on the top left side of the liquid storage tank, and the heat dissipation component is installed on the top of the water pump and is close to the thermal conductive back plate.

[0010] A further improvement is that the heat dissipation component includes a water pipe, a serpentine heat dissipation pipe, and a return pipe. The water pipe is installed at the water outlet of the water pump, the serpentine heat dissipation pipe is fixedly connected to the top of the water pipe, the return pipe is fixedly connected to the other end of the serpentine heat dissipation pipe, and its bottom extends into the interior of the liquid storage tank. The water pump is started to pump the coolant inside the liquid storage tank into the interior of the water pipe and flow to the interior of the serpentine heat dissipation pipe, which is tightly attached to the thermal conductive back plate, thereby exchanging and cooling the heat transferred from the thermal conductive back plate. The coolant after heat exchange flows back into the interior of the liquid storage tank through the return pipe, thereby realizing the recycling of the coolant and saving resources.

[0011] A further improvement is that a refrigerator is installed on the back of the liquid storage tank, and the refrigerator is used to quickly cool the coolant after heat exchange to ensure the cooling and heat dissipation effect. A turbine is installed inside the serpentine heat pipe. When the coolant flows to the middle of the serpentine heat pipe, the coolant passes through the turbine and stirs the coolant through the turbine, so that the coolant inside the serpentine heat pipe, which is still at a low temperature, is dispersed, thereby improving the heat dissipation efficiency.

[0012] A further improvement is that the fire extinguishing unit includes a connecting pipe, a water distribution pipe, a water spray hole, and an electric valve. The connecting pipe is fixedly connected to the middle part of the serpentine heat dissipation pipe, and its front end passes through the heat-conducting back plate. The water distribution pipe is fixedly connected to the front end of the connecting pipe, and a plurality of water spray holes are equidistantly arranged at the bottom of the water distribution pipe. The electric valve is installed on the outer surface of the connecting pipe. In the extreme case that the water pump control box catches fire, the electric valve is opened, and the coolant flows through the connecting pipe to the inside of the water distribution pipe, and then sprayed out from the water spray hole at the bottom of the water distribution pipe to extinguish the fire in the water pump control box, thereby preventing the fire from spreading and causing serious property losses.

[0013] A further improvement is that ventilation holes are respectively opened on the left and right outer surfaces of the water pump control box, and dustproof nets are respectively installed inside the two ventilation holes to assist in heat dissipation through the through holes. The dustproof nets are arranged to prevent external dust from entering the interior of the water pump control box, thereby causing damage to the electrical components inside the water pump control box.

[0014] A further improvement is that a display screen is installed above the front of the box door, and a control button and an alarm are installed in the middle of the front of the box door. The alarm is used to sound an alarm in time when encountering extreme situations, the operation status of the water pump control box is displayed through the display screen, and the control button is used to control the operation of the water pump control box.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The water pump control box with a heat dissipation mechanism starts the water pump to pump the coolant in the liquid storage tank to the inside of the water pipe, and then flows to the inside of the serpentine heat dissipation pipe, which is closely attached to the heat-conducting back plate, so as to exchange and cool the heat transferred from the heat-conducting back plate. The coolant after heat exchange flows back into the liquid storage tank through the reflux pipe, realizing the recycling of the coolant and saving resources.

[0017] 2. In the extreme case that the water pump control box with a heat dissipation mechanism catches fire, the electric valve is opened, and the coolant flows through the connecting pipe to the inside of the water distribution pipe, and then sprays out from the spray hole at the bottom of the water distribution pipe to extinguish the fire in the water pump control box, thereby preventing the fire from spreading and causing serious property losses.
