Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a solenoid valve accessory for a new energy vehicle with a heat dissipation function. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic components for controlling fluid automation and belong to actuators, not limited to hydraulic and pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system.

[0003] For example, an existing patent (publication number: CN214063941U) discloses a heat dissipation solenoid valve, which uses a heat dissipation fan to drive the gas flow near the heat dissipation plate as the heat dissipation fan rotates, and the heat is taken away by the gas.

[0004] However, the heat dissipation solenoid valve designed as above still has some disadvantages in actual use: the cooling fan provided in the device has a relatively slow cooling effect, and when used in summer, due to the long-term operation of the car and the high ambient temperature, the wind blown out by the rotation of the fan blades is not much different from the temperature in the air, and under the condition of long-term high-temperature heat flow, it still cannot achieve a good heat dissipation effect on the solenoid valve.

[0005] To this end, we designed a new energy vehicle solenoid valve accessory with heat dissipation function to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a new energy vehicle solenoid valve accessory with a heat dissipation function to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides a new energy vehicle solenoid valve accessory with heat dissipation function, including a solenoid valve body, a cooling fan is fixedly installed on one side of the top of the solenoid valve body, a fixing column is provided on one side of the cooling fan, one end of the fixing column is against one side of the cooling fan, a heat pipe is fixedly provided on the outer surface of the cooling fan, a first fin and a second fin are symmetrically installed in the fixing column, two ends of the heat pipe respectively pass through the first fin and the second fin and are connected with heat dissipation blocks, and a circulation component is also provided on the heat pipe.

[0008] Furthermore, a branch pipe is provided on the heat pipe near the second fin side, the branch pipe is connected to the heat pipe, and the circulation component includes a micro water pump connected to the branch pipe, and the micro water pump can pump the cooled liquid back for a new round of circulation.

[0009] Furthermore, heat-conducting fins are symmetrically arranged on both sides of the heat dissipation block, and the arrangement of the heat-conducting fins can better dissipate heat for the solenoid valve body.

[0010] Furthermore, a guide tube is fixedly installed in the fixing column, and two ends of the guide tube are respectively opposite to one side of the cooling fan and one side of the cooling block. The setting of the guide tube can better guide the airflow to the cooling block for heat dissipation.

[0011] Furthermore, the shape of the guide tube is a "trumpet" shape that is larger at the front and smaller at the back. The "trumpet" shape allows the hot air flow to pass through the large pipe at one end and enter the contraction pipe at the other end. When the gas flow rate increases, the pressure will decrease, thereby causing the temperature to drop, further cooling the air flow.

[0012] Furthermore, plug-in ports are symmetrically provided on both sides of the heat dissipation block, and both ends of the heat conducting pipe are fixedly plugged into the plug-in ports.

[0013] Furthermore, a cavity is provided in the inner side wall of the fixing column, and the first fin and the second fin are both fixedly arranged in the cavity. The arrangement of the cavity makes the overall device more space-saving.

[0014] Furthermore, two sliding openings are symmetrically provided at both ends of the inner side wall of the fixing column, and the heat conducting pipe is inserted into the sliding openings. The setting of the sliding openings makes the heat conducting pipe more stable when connecting the first fin and the second fin without the problem of biased movement.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the airflow blown out by the cooling fan is cooled by the liquid in the heat conducting pipe, and then the cooled airflow is blown to the heat dissipation block through the guide pipe, and then the heat dissipation block cools the solenoid valve body; when the hot liquid passes through the first fin, the first fin dissipates the heat, and then the micro water pump pumps the cooled liquid back again, and the liquid passes through the second fin and circulates the heat to cool the airflow blown out by the cooling fan and the fixed column, which can alleviate the temperature of the airflow blown out by the existing cooling fan to a certain extent, and has an excellent cooling and heat dissipation effect on the solenoid valve body.

[0016] Compared with the prior art, the beneficial effect of the utility model is that through the specific shape of the guide tube, when the hot air flow passes through the large pipe at one end and enters the contraction pipe at the other end, the gas flow rate increases and the pressure decreases, thereby causing the temperature to drop, further cooling the air flow and enhancing the cooling effect of the heat conduction pipe.

[0023] See also Figure 1-4 The utility model provides a technical solution: a solenoid valve accessory for new energy vehicles with a heat dissipation function, comprising a solenoid valve body 1, a heat dissipation fan 2 is fixedly installed on one side of the top of the solenoid valve body 1, a fixing column 3 is arranged on one side of the heat dissipation fan 2, one end of the fixing column 3 is against one side of the heat dissipation fan 2, a heat conduction pipe 4 is fixedly arranged on the outer surface of the heat dissipation fan 2, a first fin 5 and a second fin 9 are symmetrically installed in the fixing column 3, two ends of the heat conduction pipe 4 respectively penetrate the first fin 5 and the second fin 9 and are connected with a heat dissipation block 6, and a circulation component is also arranged on the heat conduction pipe 4.

[0024] A branch pipe 7 is provided on the heat conducting pipe 4 near the second fin 9 , the branch pipe 7 is connected to the heat conducting pipe 4 , and the circulation component includes a micro water pump 8 connected to the branch pipe 7 .

[0025] Heat conducting plates 10 are symmetrically arranged on both sides of the heat dissipation block 6 .

[0026] Insertion ports 13 are symmetrically provided on both sides of the heat dissipation block 6 , and both ends of the heat pipe 4 are fixedly inserted into the insertion ports 13 .

[0027] During specific implementation, the cooling fan 2 and the cooling block 6 are turned on, and the liquid in the heat pipe 4 cools down the airflow blown out by the cooling fan 2, and then the cooled airflow is blown to the cooling block 6 through the fixed column 3, and then the cooling block 6 cools the solenoid valve body 1. When the hot liquid passes through the first fin 5, the first fin 5 dissipates the heat, and then the micro water pump 8 pumps the cooled liquid back again, and the liquid passes through the second fin 9 for circulation and heat dissipation to cool down the airflow blown out by the cooling fan 2 and the fixed column 3. To a certain extent, the temperature of the airflow blown out by the existing cooling fan 2 can be alleviated, and excellent cooling and heat dissipation effect can be achieved on the solenoid valve body 1.

[0028] See also Figure 1-4 As shown, a guide tube 12 is also fixedly installed in the fixing column 3, and two ends of the guide tube 12 are respectively opposite to one side of the heat dissipation fan 2 and one side of the heat dissipation block 6.

[0029] The guide tube 12 is shaped like a trumpet with a larger front and a smaller back.

[0030] In specific implementation, when the cooled air flow is blown toward the heat sink 6 through the air guide tube 12, due to the specific shape of the air guide tube 12, when the hot air flow passes through the large pipe at one end and enters the contraction pipe at the other end, the gas flow rate increases and the pressure decreases, thereby causing the temperature to drop, further cooling the air flow and enhancing the cooling effect of the heat pipe 4, that is, the air blown out by the cooling fan 2 has a good cooling and heat dissipation effect.

[0031] See also Figure 1-4 A cavity 11 is provided in the inner wall of the fixing column 3 , and the first fin 5 and the second fin 9 are both fixedly disposed in the cavity 11 . The provision of the cavity 11 makes the overall device more space-saving.

The setting of the sliding openings 14 makes the heat pipe 4 more stable when connecting the first fin 5 and the second fin 9 without the problem of biased movement.

[0033] Working principle: when the solenoid valve body 1 is cooled, the cooling fan 2 and the heat sink 6 are turned on, and the liquid in the heat pipe 4 cools the airflow blown out by the cooling fan 2, and then the cooled airflow is blown to the heat sink 6 through the guide pipe 12. Due to the specific shape of the guide pipe 12, when the hot air flow passes through the large pipe at one end and enters the contraction pipe at the other end, the gas flow rate increases, and the pressure decreases, which leads to a drop in temperature, further cooling the airflow, and enhancing the cooling effect of the heat pipe 4, that is, it has a good cooling and heat dissipation effect on the air blown out by the cooling fan 2, and then the heat sink 6 performs heat dissipation work on the solenoid valve body 1. When the liquid with heat passes through the first fin 5, the first fin 5 dissipates the heat, and then the micro water pump 8 pumps the cooled liquid back again, and the liquid passes through the second fin 9 for circulation and heat dissipation to cool the airflow blown out by the cooling fan 2 and the fixed column 3, which can alleviate the temperature of the airflow blown out by the existing cooling fan 2 to a certain extent, and has an excellent cooling and heat dissipation effect on the solenoid valve body 1.
