Detailed Description
For ease of understanding, the specific structure and operation of the present invention is further described herein with reference to FIGS. 1-2:
the specific structure of the invention is shown in fig. 1-2, and mainly comprises a motor cavity 40, wherein a motor is arranged in the motor cavity 40, and the motor cavity 40 is provided with a cavity which is positioned outside a motor rotor cavity. The cavity intussuseption is filled with the coolant liquid, and when electric motor rotor generated heat, heat transfer realized the heat exchange in the coolant liquid in the cavity to lower the temperature to the motor.
Still include cooler 10, cooler 10 is hollow structure, and its inside is equipped with cooling chamber 11, and cooling chamber 11 and motor chamber 40 intercommunication, the coolant liquid after the heat transfer flows into cooling chamber 11 along hot-water line 30 in, cools off.
The cooling chamber 11 surrounds the inner pipe 12 to increase a contact area, the inner pipe 12 is connected to the water pump 50, the water pump 50 pumps water, and the external water flows from the inner pipe 12 to contact the cooling chamber 11 to exchange heat with the cooling liquid inside the cooling chamber 11, thereby cooling the cooling liquid. After being cooled, the cooling liquid flows into the motor cavity 40 through the cold water pipe 20 to continuously cool the motor, and a circulation is formed.
By adopting the mode, on one hand, the cooling liquid in the cooling loop is kept not to pass through the outside, so that the pipeline is prevented from being blocked by external impurities, and on the other hand, the converted heat can be stored through the water outlet 51 and put into other places for use. In addition, the cooler 10 is connected to the water inlet 60 by means of a flange, so that the disassembly is facilitated, and if the cooling efficiency is insufficient, the number of the cooler 10 and the pipes can be increased.
In order to drive the circulation of the cooling liquid in the pipeline, a centrifugal pump wheel rotating along with the motor rotor is arranged at the interface of the cold water pipe 20 and the motor cavity 40, and the centrifugal pump wheel is used for pressurizing and driving the cooling liquid to flow.
Since the cooler 10 is not directly installed on the motor cavity 40, it can be placed in water alone, and the motor cavity 40 can be placed on land or in water according to the use requirement of the motor without being limited to the location of the cooler 10, and the cooler 10 is not installed on the motor cavity 40, which also reduces the volume and facilitates the placement in a small pit.
As a modification of this embodiment, in order to adsorb iron pieces in the pipeline due to corrosion or the like, magnetic steel 111 is provided inside the cooling chamber 11. After the cooling liquid enters the cooling cavity 11 along the hot water pipe 30, the cooling liquid can contact the magnetic steel 111 at the first time, and the iron chips carried by the cooling liquid can be adsorbed to prevent the cooling liquid from blocking the pipeline. In addition, the magnetic steel 111 can adsorb the debris in the inner pipe 12, and prevent the foreign materials of the external water from entering the water pump 50.
In order to prevent impurities from entering through the inner pipe 12, the filtering net 122 is arranged in the embodiment to intercept larger impurities, and the magnetic short pipe 121 is also arranged to adsorb smaller iron filings on the inner wall.
It will, of course, be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
