Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to the drawings.
As shown in FIG. 1, the utility model is a schematic diagram of an overall structure of a water cooling system capable of draining water rapidly, comprising a cooling tower 1, a delivery water pump 2 and a cooler 3.
The cooling tower 1 is placed on the ground, the cooling tower 1 is a conventional water circulation cooling tower, the bottom is a water tank 11, the upper part is a cooling tower 12, a cooling water pump 13 is arranged in the cooling tower, water in the water tank 11 is pumped to the top of the cooling tower 12, the cooling water pump is sprayed by a spray 14 to increase the contact area between the water and air, and a cooling fan is assisted to dissipate heat in the water, so that the water falls freely again and flows back into the water tank 11.
The water cooling system is provided with a delivery water pump 2; the conveying water pump 2 is vertically arranged, the water inlet is arranged below, and the water outlet is arranged above; the delivery water pump 2 is arranged above the outside of the water tank 11, one end of the water pipe is inserted into the water tank 11, and the other end is connected with the water inlet of the delivery water pump 2. The conveying water pump 2 is an impeller type water pump.
A cooler 3 is arranged above the conveying water pump 2; the cooler 3 is vertically arranged, the water inlet is positioned at the bottom of the cooler 3, and the water return port is positioned at the top of the cooler 3; the water outlet of the conveying water pump 2 is connected with the water inlet of the cooler 3, and is vertically connected with each other as much as possible through a straight pipe. The medium channel of the cooler 3 is generally antifreeze fluid or heat dissipation oil, which can be selected according to the specific condition of the ambient temperature, so as to ensure that freezing cannot occur; the media channel is connected to the device. The fluid medium in the medium channel and the water in the water cooling system exchange heat in the cooler 3, so that heat dissipation of the equipment is realized.
The water return port of the cooler 3 is connected with the cooling tower 1 through a pipeline, or directly returns to the water tank 11, or is connected with the spray 14 for spraying.
After the water cooling system is operated, the whole pipeline and the components are filled with water by the water conveying pump 2; when the system is stopped, water cannot actively flow out of the pipelines and the elements due to the atmospheric pressure, so that the water can remain in the system, icing and volume expansion can occur below 0 ℃, and the risks of pipeline and element expansion exist.
The improvement of the utility model is that a part of the water return pipeline of the cooler 3 is positioned at the highest point of the water cooling system (namely higher than the cooler 3 and also higher than the cooling tower 1), and a drainage device is arranged at the highest position of the water return pipeline of the cooler 3; as shown in fig. 1, the drainage device is an electric control drainage device 4; of course, a manual drainage device is also possible according to the need, but the electric control drainage device 4 is preferable because the cooling tower 1 is higher, the cooler 3 is also installed higher, and the highest point of the corresponding water return pipeline is also higher, if manual operation is adopted, the worker is required to ascend a height, and the operation is inconvenient.
One end of the drainage device is connected with the water return pipe, and the other end of the drainage device is communicated with the atmosphere; the drain may be controlled to close or communicate with both ends (i.e., the return line is vented to atmosphere).
The electric control drainage device 4 can be an electric control switch valve, such as an electric control ball valve and an electric control butterfly valve; or may be an electromagnetic directional valve as shown. In industrial production sites, the electromagnetic directional valve is more commonly used, so the electromagnetic directional valve is adopted, and the replacement accessory is relatively more commonly equipped.
When the operation is stopped and the ambient temperature is below 0 DEG, and the freezing risk exists, and the water in the water cooling system is required to be drained, as shown in fig. 2, the electric control drainage device 4 is started, and the return pipe is communicated with the atmosphere; at this time, air is introduced into the pipeline, water in the pipeline at the left side of the system flows downwards along the pipeline and finally flows into the water tank 11; the water in the right pipeline and the elements of the system is also subjected to the action of gravity and moves reversely, and flows downwards from the cooler 3 and the delivery water pump 2 through the pipeline and finally flows into the water tank 11. Because the conveying water pump 2 adopts an impeller type water pump, when the water pump stops working (is static), the inlet and the outlet do not form sealing, so the water in the pipeline can return to the water tank 11 through the conveying water pump 2.
The cooling water pump 13 can also adopt an impeller type water pump, and can automatically drain the water in the pipeline of the cooling tower 12 back into the water pool 1 after the machine is stopped.
The water tank 11 is positioned at the lowest position, and when the highest point of the whole system is communicated with the atmosphere, water flows back into the water tank 11 under the action of gravity, so that the water in the pipeline, the cooler 3 and the conveying water pump 2 is completely emptied.
The utility model relates to a water cooling system capable of rapidly draining water, which adopts an electric control drainage device 4, a control circuit of the electric control drainage device can be connected with a control system of a cooling tower 1, when the electric control drainage device is stopped, the electric control drainage device 4 is automatically started for a period of time (a preset timer) while the cooling tower 1 is closed, and a water return pipe is communicated with the atmosphere for a period of time, so that the water in the system can be automatically drained. By arranging the control system of the cooling tower 1, the weather temperature change condition can be synchronously considered, when the temperature is reduced to below 0 ℃ in winter, the cooling tower 1 stops working and simultaneously automatically starts an electric control drainage device 4 for a period of time, and the system drains water; when the temperature rises, the electric control drainage device 4 is not automatically started when the cooling tower 1 stops working, so that water is reserved in the closed system under the action of atmospheric pressure, and water circulation can be directly realized when the system is recovered, and the process of pumping water in the system again is avoided.
When the electric control drainage device 4 adopts an electromagnetic reversing valve, an interface is reasonably arranged, and when the electric control drainage device works normally, the electromagnetic reversing valve is in a non-electrified state, so that electric energy is saved, and the service life of the electromagnet is prolonged; when the system needs to drain water, the electromagnet is powered again, the system drains water, and then the power is cut off.
The water cooling system capable of draining water rapidly is improved on the existing water cooling system, is simple in structure and is easy to reform and realize; the water in the elements such as the cooler, the water pump, the pipeline and the like can be discharged completely by simply operating the water discharging device, the program is simple and convenient, and the automatic operation can be realized, so that the labor is greatly reduced.
While the preferred embodiments of the present utility model have been described in detail, the present utility model is not limited to the embodiments described above, and various equivalent modifications and substitutions can be made by those skilled in the art without departing from the spirit of the present utility model, and these are intended to be included in the scope of the present utility model as defined in the appended claims.
