A temperature measuring device for a hydrogen solenoid valve

Abstract

The present invention relates to the technical field of solenoid valves, and particularly relates to a temperature measurement device for a hydrogen solenoid valve, including a solenoid valve body, on which an electromagnetic coil is fixedly installed, an outer wall of the electromagnetic coil is sleeved with a heat conduction structure, a mounting ring is movably connected to an outer wall of the heat conduction structure close to the solenoid valve body, and a fixing ring is rotatably connected to an outer wall of the mounting ring. After the mounting plate rotates in the present invention, a temperature measurement probe measures temperatures at different positions on the outside of the heat sink. The temperature measurement space passes through the cooled heat conduction sleeve, and the cooling of the coolant reduces the temperature inside the temperature measurement space, which is equivalent to compensating for the influence of the ambient temperature and resetting the temperature inside the temperature measurement space. The temperature measurement probe re-measures the temperature inside the temperature measurement space. Since the mounting plate and the baffle have a heat insulation effect, the temperature inside the temperature measurement range is the temperature of the electromagnetic coil led out from the heat conduction sleeve, thus avoiding the influence of the ambient temperature on the monitoring result during long-term detection.

Description

Technical Field

[0001] The present invention relates to the technical field of solenoid valves, and particularly to a temperature measuring device for a hydrogen solenoid valve. Background Art

[0002] Solenoid valves can cooperate with various control systems to achieve expected automated operations and are widely used as automatic electromagnetic actuators in fields such as automotive automatic transmissions, machining, and aerospace. Among them, electric vehicles using hydrogen fuel cells use hydrogen solenoid valves to control the flow of hydrogen. During the operation of solenoid valves, short circuits caused by the burnout of the insulation layer due to overheating and mechanical deformation caused by thermal expansion are the main reasons for solenoid valve failure. As an electromagnetic heat source, the temperature of the solenoid valve winding is often higher than that of other components, and hydrogen is a flammable gas. Therefore, it is particularly important to ensure the stable operation of hydrogen solenoid valves. Thus, measuring and monitoring the temperature of the solenoid valve winding is an important factor in ensuring the reliable operation of the entire automatic system.

[0003] In the prior art, in order to measure the temperature at the solenoid valve winding, a temperature measuring device is usually provided at the solenoid valve winding to monitor the temperature. However, the ambient temperature inside the vehicle gradually increases as the vehicle runs, and the measurement will be affected by the ambient temperature. Moreover, when the temperature of the solenoid valve rises, the insulation layer will be burned out due to overheating, resulting in short circuits, thermal expansion, and solenoid valve failure. Traditional temperature measuring devices cannot cool down and protect the solenoid valve either. Summary of the Invention

[0008] In the above temperature measuring device for a hydrogen solenoid valve, the filling mechanism includes an annular storage bag, the inside of the annular storage bag is filled with heat dissipation silicone grease, a plurality of liquid outlet channels are arranged inside the heat conduction sleeve, one end of the liquid outlet channel is communicated with the inside of the annular storage bag, a discharge hole is formed inside the heat conduction sleeve, the end of the liquid outlet channel away from the annular storage bag is communicated with the discharge hole, an annular baffle is fixedly connected to the outer wall of the annular storage bag, and the annular baffle is fixedly connected to the outer wall of the connecting ring piece.

[0009] In the above temperature measuring device for a hydrogen solenoid valve, a liquid pushing block is fixedly connected to the outer wall of one side of each baffle away from the temperature measuring probe, and the outer wall of the liquid pushing block is slidably connected to the outer wall of the heat conduction sleeve.

[0010] In the temperature measurement device of a hydrogen solenoid valve described above, a constant pressure valve is fixedly installed on the outer wall of the liquid storage pipe.

[0011] In the temperature measurement device of a hydrogen solenoid valve described above, the liquid outlet mechanism includes a spherical liquid outlet head and a spherical cavity. The spherical cavity is opened at the end of the baffle plate. The spherical liquid outlet head is movably connected to the inside of the spherical cavity.

[0014] In the temperature measurement device of a hydrogen solenoid valve described above, a plurality of connecting grooves are opened on the outer wall of the mounting ring. One end of the mounting plate is fixedly connected to a connecting head. The mounting plate is installed inside the connecting groove through the provided connecting head.

[0015] Compared with the existing technology, the advantages of the temperature measurement device of this hydrogen solenoid valve are as follows:

[0016] 1. After the mounting plate rotates, the position of the temperature measurement space jointly formed by the mounting plate, the baffle plate, and the heat dissipation fins will also change accordingly, enabling the temperature measurement probe to measure different positions on the outside of the heat dissipation fins. When the temperature measurement space passes through the heat conduction sleeve after cooling, the cooling of the coolant reduces the temperature inside the temperature measurement space, which is equivalent to compensating for the influence of the ambient temperature and resetting the temperature inside the temperature measurement space. The temperature measurement probe re-measures the temperature inside the temperature measurement space. Since the mounting plate and the baffle plate have heat insulation effects, the temperature inside the temperature measurement range is the temperature of the electromagnetic coil led out from the heat conduction sleeve, thus avoiding the influence of the ambient temperature on the monitoring result during long-term detection.

[0017] 2. When the temperature of the electromagnetic coil is detected to be relatively high, the driving device will be used to drive the mounting ring to rotate, and it will stop after the temperature drops. When rotating, the mounting ring will drive the temperature measuring structure to slide on the surface of the heat conducting structure. When the temperature measuring structure moves, the liquid outlet mechanism will send out the coolant inside the liquid storage pipe from the bottom of the baffle plate and evenly apply it on the surface of the heat conducting structure. By the evaporation of the coolant, the temperature of the surface of the heat conducting structure can be reduced, which can further play a role in cooling and prevent the electromagnetic coil from being damaged at too high a temperature.

[0018] 3. When measuring the temperature, the temperature measuring probe measures the temperature in the temperature measuring space, reducing the influence of the external environment temperature on the measurement result. Multiple temperature measuring probes can separately measure the temperature of multiple temperature measuring spaces, and the average value can be obtained through simple calculation, making the measured temperature value more accurate. Moreover, based on the measurements of multiple temperature measuring probes, the overall temperature distribution of the electromagnetic coil can be intuitively understood, and it can be judged whether there is local overheating or local defects in the electromagnetic coil.

[0019] 4. During installation, the heat conducting sleeve is sleeved outside the electromagnetic coil, and the fixing ring is fixed on the outer wall of the solenoid valve body. When pushing the mounting ring, the annular storage bladder will be squeezed, so that the heat dissipation silicone grease inside the annular storage bladder is extruded and filled between the heat conducting sleeve and the electromagnetic coil, so as to ensure good contact between the heat conducting sleeve and the electromagnetic coil and enable the heat conducting sleeve to conduct the heat dissipated by the electromagnetic coil, thus making the temperature measurement more accurate.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0034] Refer to Figures 1 - 11, a temperature measurement device for a hydrogen solenoid valve, comprising a solenoid valve body 1, on which an electromagnetic coil 2 is fixedly installed. Considering that the solenoid valve structure formed by the solenoid valve body 1 and the electromagnetic coil 2 has been relatively maturely applied in the prior art, the specific internal structure of the solenoid valve body 1 and the electromagnetic coil 2 will not be further described. A heat conduction structure 6 is sleeved on the outer wall of the electromagnetic coil 2. An installation ring 5 is movably connected to the outer wall of the heat conduction structure 6 close to the solenoid valve body 1. A fixing ring 3 is rotatably connected to the outer wall of the installation ring 5. A positioning structure 4 is fixedly connected to the outer wall of the fixing ring 3. The fixing ring 3 is installed on the outside of the solenoid valve body 1 through the provided positioning structure 4. A plurality of uniformly distributed temperature measurement structures 7 are slidably connected to the outer wall of the heat conduction structure 6. The number of the temperature measurement structures 7 is preferably four. One end of the temperature measurement structure 7 is movably connected to the heat conduction structure 6. A secondary heat dissipation structure 8 is fixedly connected to the outer wall of each temperature measurement structure 7. An information transmitting device 9 is fixedly installed on the installation ring 5. A driving device 10 for driving the installation ring 5 to rotate is fixedly connected to the inner side of the fixing ring 3; the heat conduction structure 6 includes a heat conduction sleeve 14, and a plurality of uniformly distributed heat dissipation fins 15 are fixedly connected to the outer wall of the heat conduction sleeve 14. The heat dissipation fins 15 are all annular structures, and a plurality of heat dissipation fins 15 are arranged parallel to each other; the temperature measurement structure 7 includes a mounting plate 16. A plurality of baffles 17 are fixedly connected to the side of each mounting plate 16 close to the heat conduction sleeve 14. The gap between every two adjacent baffles 17 is movably connected to the outer wall of the heat dissipation fin 15. The heat dissipation fin 15, the mounting plate 16, and the baffle 17 are all made of heat-insulating materials. A plurality of temperature measurement probes 18 are fixedly connected to the middle of the side of the mounting plate 16 close to the heat conduction sleeve 14. A plurality of baffles 17 are uniformly distributed on both sides of the temperature measurement probes 18. The baffles 17 on both sides are separated from the heat dissipation fin 15 at the gap and form individual temperature measurement spaces with the heat dissipation fin 15. A plurality of temperature measurement probes 18 are respectively inside each individual temperature measurement space. During temperature measurement, the temperature measurement probes 18 measure the temperature inside the temperature measurement space, reducing the influence of the external environment temperature on the measurement result. A plurality of temperature measurement probes 18 can separately measure the temperatures of a plurality of temperature measurement spaces, and the average value can be obtained through simple calculation, making the measured value more accurate. Moreover, according to the measurements of a plurality of temperature measurement probes 18, the overall temperature distribution of the electromagnetic coil 2 can be intuitively understood, and it can be judged whether there is local overheating or local defects in the electromagnetic coil 2;The secondary heat dissipation structure 8 includes a liquid storage pipe 20, the inside of the liquid storage pipe 20 is filled with a coolant, and the inner wall of the liquid storage pipe 20 is fixedly connected and communicated with a plurality of liquid guide pipes 22. An out-liquid mechanism is fixedly installed inside one side of the baffle 17 close to the heat conduction sleeve 14. One end of the liquid guide pipe 22 away from the liquid storage pipe 20 passes through the mounting plate 16 and the baffle 17 and extends into the inside of the out-liquid mechanism. When it is detected that the temperature of the electromagnetic coil 2 is relatively high, the mounting ring 5 will be driven to rotate by the driving device 10 and stop after the temperature drops. When rotating, the mounting ring 5 will drive the temperature measuring structure 7 to slide on the surface of the heat conduction structure 6. When the temperature measuring structure 7 moves, the out-liquid mechanism will send out the coolant inside the liquid storage pipe 20 from the bottom of the baffle 17 and evenly apply it on the surface of the heat conduction structure 6, and the temperature of the surface of the heat conduction structure 6 is reduced by the evaporation of the coolant, which can further play a role in cooling and temperature reduction, avoiding damage to the electromagnetic coil 2 at too high a temperature. Moreover, after the mounting plate 16 rotates, the position of the temperature measuring space jointly formed by the mounting plate 16, the baffle 17 and the heat sink 15 will also change accordingly, so that the temperature measuring probe 18 measures different positions outside the heat sink 15. At the position of the heat conduction sleeve 14 where the temperature measuring space passes through after temperature reduction, the temperature reduction of the coolant reduces the temperature inside the temperature measuring space, which is equivalent to compensating for the influence of the ambient temperature and resetting the temperature inside the temperature measuring space. The temperature measuring probe 18 re-measures the temperature inside the temperature measuring space. Since the mounting plate 16 and the baffle 17 have heat insulation effects, the temperature inside the temperature measuring range is the temperature of the electromagnetic coil 2 derived from the heat conduction sleeve 14, thus avoiding the influence of the ambient temperature on the monitoring result during long-term detection. At this time, if the temperature measured by the temperature measuring probe 18 is still relatively high, it means that the temperature inside the electromagnetic coil 2 is relatively high.;

The outer wall of the filling mechanism is fixedly connected with a connecting ring piece 12. A bearing 13 is sleeved outside the connecting ring piece 12.

During installation, the heat-conducting sleeve 14 is sleeved outside the electromagnetic coil 2, and the fixing ring 3 is fixed on the outer wall of the solenoid valve body 1. Pushing the installation ring 5 will squeeze the annular storage bladder 28, so that the heat-conducting silicone grease inside the annular storage bladder 28 is extruded and filled between the heat-conducting sleeve 14 and the electromagnetic coil 2, so that there is good contact between the heat-conducting sleeve 14 and the electromagnetic coil 2, enabling the heat-conducting sleeve 14 to conduct the heat dissipated by the electromagnetic coil 2.

The outer wall of the liquid pushing block 19 is slidably connected to the outer wall of the heat-conducting sleeve 14. The liquid pushing block 19 is provided to smear the discharged coolant evenly, so that the coolant is evenly smeared on the outer wall of the heat-conducting sleeve 14, making the coolant evaporate faster to quickly cool down the heat-conducting sleeve 14.

[0038] Among them, a constant pressure valve 21 is fixedly installed on the outer wall of the liquid storage pipe 20 to maintain the pressure inside the liquid storage pipe 20 after the coolant inside the liquid storage pipe 20 flows out, preventing the liquid storage pipe 20 from forming negative pressure to block the outflow of the coolant.

When the spherical liquid outlet head 23 rolls on the surface of the heat-conducting sleeve 14, the coolant will be taken out. The convex blocks 25 can make the coolant fully fill the inside of the spherical cavity 24, making the liquid outlet stable.

[0040] Among them, the positioning structure 4 includes a threaded sleeve 34. The outer wall of the threaded sleeve 34 is fixedly connected to the outer wall of the connecting block 33. The inner wall of the threaded sleeve 34 is threadedly connected to a threaded rod 35. One end of the threaded rod 35 close to the solenoid valve body 1 is fixedly connected to a pressing block 36. When the threaded rod 35 is rotated, the threaded rod 35 will move along the threaded sleeve 34, making the pressing block 36 stick to the outer wall of the solenoid valve body 1, clamping the whole device on the outer wall of the solenoid valve body 1.

[0041] Among them, the driving device 10 includes a small motor 37. The outer wall of the small motor 37 is fixedly connected to the inner wall of the fixed ring 3.

[0042] Among them, a plurality of connecting grooves 26 are formed in the outer wall of the mounting ring 5. One end of the mounting plate 16 is fixedly connected with a connecting head 27. The mounting plate 16 is mounted inside the connecting groove 26 through the provided connecting head 27. The temperature signal measured by the mounting plate 16 is transmitted to the information transmitting device 9 through the connection between the connecting head 27 and the connecting groove 26 and transmitted out.
