Detailed Description
Example one
As shown in fig. 1, a high temperature pump includes a pump body 113, and the pump body 113 includes a water inlet section, a mixed flow impeller, a space guide vane, a lift pipe, and a water outlet section. The upper end of the pump body 113 is sequentially provided with a heat insulation plate 112, a first base body 106, a second base body 105 and a third base body 101 from bottom to top. The heat shield 112 is made of stainless steel. The first base body 106 and the second base body 105, and the second base body 105 and the third base body 101 are connected through bolts, so that the base body can be disassembled, and assembly and maintenance are facilitated. A main shaft 201 is installed in the pump body 113, one end of the main shaft 201 extends out of the third seat body 101, and a second bearing 103 is installed between the main shaft 201 and the third seat body 101, and because the second bearing 103 is far away from the pump body 113, heat dissipation is not needed. One end of the main shaft 201, which extends out of the first seat body 101, is connected with the motor through the coupler 102, so that the motor can drive the main shaft 201 to rotate by starting the motor.
The insulation board 112 is provided with a fixing portion 111 so that the insulation board 112 can be fixedly mounted on a corresponding device.
Grooves are formed in the contact ends of the third seat body 101 and the second seat body 105, so that a first cavity is formed between the third seat body 101 and the second seat body 105. The first fan blades 202 are arranged on the main shaft 201 in the first cavity, and the air inlets 104 communicated with the first cavity are uniformly distributed on the base body three 101. When the main shaft 201 rotates, the first fan blades 202 rotate along with the main shaft, so that air flow is generated, and external cold air flow enters the first cavity through the air inlet hole 104. In order to prevent foreign matters such as dust from entering the first cavity, a filter screen is installed in the air inlet hole 104.
A first through hole 204 communicated with the first cavity is formed in the second base body 105, and an air cooling heat dissipation device 300 fixedly installed on the main shaft 201 is arranged in the first through hole 204. Specifically, as shown in fig. 2, the air-cooled heat sink 300 includes a sleeve 303, and the sleeve 303 is fixedly mounted on the main shaft 201 by a flat key. A plurality of groups of second radiating fins are fixedly connected to the outer circumferential surface of the sleeve 303 at intervals along the axial direction, each group of second radiating fins comprises a plurality of fan-shaped fins 301 fixedly mounted on the sleeve 303 at intervals along the circumferential direction, and radiating holes 302 are uniformly distributed in the fan-shaped fins 301. The sleeve 303 and the fan-shaped fins 301 are made of metal which is easy to conduct heat, so that heat on the spindle 201 can be transferred to the fan-shaped fins 301. When the spindle 201 rotates, air flow generated by the first rotating fan blades 202 enters the first through holes 204, and the air flow passes through the spaces among the fan-shaped fins 301 and the heat dissipation holes 302, so that heat on the fan-shaped fins 301 is taken away, and the spindle 201 is dissipated.
The second cavity 205 is formed in the first seat body 106, and the second cavity 205 is in through connection with the first through hole 204 through the second through hole formed in the first seat body 106, so that the airflow entering the first cavity can enter the second cavity 205. A first bearing 108 is installed in the second through hole, and the main shaft 201 is installed on the first bearing 108. Since the first bearing 108 is close to the pump body 113, heat dissipation needs to be performed on the first bearing 108. Specifically, the first heat dissipation fins 107 are uniformly distributed on the first bearing 108 along the circumferential direction, the first heat dissipation fins 107 are made of metal easy to conduct heat, and the air flow passing through the first through holes 204 can pass through the space between every two adjacent first heat dissipation fins 107, so that heat is dissipated to the first heat dissipation fins 107.
In order to enable the airflow passing through the first through hole 204 to fully flow between the two adjacent first radiating fins 107, a flow guide plate is arranged between the first through hole 204 and the second through hole. Specifically, as shown in fig. 3, the baffle includes a baffle body 401 fixedly connected to the first seat body 106, the main shaft 201 passes through a fifth through hole formed in the baffle body 401, and a sealing sleeve 403 is installed between the baffle body 401 and the main shaft 201, so that the airflow flowing out of the first through hole 204 does not pass through the fifth through hole. A ventilation channel 402 is arranged in the guide plate body 401, the upper side of the ventilation channel 402 is communicated with the first through hole 204, and the lower side of the ventilation channel 402 is communicated with the second through hole, so that airflow in the first through hole 204 can flow into the second through hole through the ventilation channel 402, further flows between two adjacent first radiating fins 107 and then flows into the second cavity 205.
In order to increase the flow rate of the air flow, the air flow can flow in the first through hole 204, the ventilation channel 402 and the second through hole relatively quickly, so that the fan-shaped fin 301 and the first heat dissipation fin 107 can be fully dissipated, and the second fan blade 206 is mounted on the main shaft 201 in the second cavity 205. When the main shaft 201 rotates, the second fan blade 206 rotates together, so that the airflow passes through the first through hole 204, the ventilation channel 402 and the second through hole relatively quickly. Air outlet holes 110 communicated with the second cavity 205 are uniformly distributed on the first seat body 106, and hot air flow is discharged through the air outlet holes 110. The second rotating fan blade 206 can also form a negative pressure environment in the second cavity 205, so that the cold airflow flows into the first cavity faster, and the airflow flowing into the first cavity flows into the second cavity 205.
The main shaft 201 located at the lower part of the second fan blade 206 is sleeved with a water-cooling heat dissipation device 500. Specifically, as shown in fig. 4 and 5, the water-cooled heat dissipation device 500 includes a heat dissipation body 501, the cross-sectional shape of the heat dissipation body 501 is "i" shaped, and the heat dissipation body 501 is made of metal which is easy to conduct heat. The heating body 501 is fixedly connected with a supporting rod 502, and the supporting rod 502 is fixedly connected with the cavity wall of the second cavity 205. The heat radiator 501 is provided with a third through hole 506 through which the spindle 201 penetrates, and the inner diameter of the third through hole 506 is larger than the outer diameter of the spindle 201. A cooling water channel 508 spirally wound around the third through hole 506 is provided in the heating body 501. One end of the cooling water channel 508 is connected to the water inlet pipe 109, and the other end of the cooling water channel 508 is connected to the water outlet pipe 504. The heat radiating body 501 can thus be radiated by the cooling water by injecting the cooling water, so that the heat conducted from the spindle 201 to the heat radiating body 501 is continuously absorbed by the cooling water.
In order to improve the utilization efficiency of the cooling water, three radiating fins 503 are uniformly distributed on the radiating body 501 along the circumferential direction, and the three radiating fins 503 are made of metal which is easy to conduct heat. The airflow entering the second cavity 205 can pass through the space between the adjacent three cooling fins 503, so that the three cooling fins 503 can be cooled by air, and the heat of the heat radiator 501 can be dissipated; the cooling water can be radiated, so that the use efficiency of the cooling water is improved. Accordingly, the lower end of the third heat dissipating fin 503 is flush with the air outlet 110. Thereby allowing the hot gas stream, which has been sufficiently heat absorbed, to be discharged from the gas outlet hole 110. The air flow flows from the low-temperature area to the high-temperature area, so that heat dissipation can be performed step by step, the air flow is fully utilized, and the heat dissipation performance is guaranteed.
Example two
The difference between the present embodiment and the embodiment is that a side air duct 203 is disposed on the second base 105, one end of the side air duct 203 is communicated with the first cavity, and the other end of the side air duct 203 is communicated with the upper side of the ventilation cavity 402. A part of cold air flow in the first cavity can flow into the ventilation cavity channel 402 through the side air channel 203 and further flow into the second through hole, so that the air flow entering the second through hole is ensured to have a certain proportion of cold air flow, and the heat dissipation efficiency of the first heat dissipation fin 107 is improved.
EXAMPLE III
The difference between the present embodiment and the embodiment is that the water cooling plate 601 is installed on the upper end of the heat insulation plate 112, and the water cooling plate 601 is made of a material that is easy to conduct heat. The water cooling plate 601 is internally provided with a spiral water channel 603. One end of the spiral water channel 603 is connected with the water outlet pipe 504, and the other end of the spiral water channel 503 is provided with a water outlet 602. A guide bearing 114 is installed in the heat shield plate 112, and the upper end of the guide bearing 114 is in contact with the lower end of the water cooling plate 601. The cooling water flowing out of the water outlet pipe 504 enters the spiral water channel 603, so that the water-cooling plate 601 can radiate heat to the heat-insulating plate 112 and the guide bearing 114. By passing cooling water into the water-cooling plate 601, the utilization efficiency of the cooling water is further improved, and heat dissipation of the guide bearing 114 and the heat insulating plate 112 is also achieved.
A certain gap can be left between the lower end of the heat radiator 501 and the upper end of the water-cooling plate 601, so that the airflow can pass through the third through hole 506, and the spindle 201 can be cooled by air cooling.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
