Abstract
Description
Technical Field
[0001] The present application relates to the technical field of solenoid valve devices, and in particular to a large-flux solenoid valve. Background Art
[0002] The working principle of a solenoid valve is to generate a magnetic field by energizing the electromagnetic coil, which attracts the iron core to move, thereby driving the valve core to control the flow of fluid. When the electromagnetic coil is energized, the magnetic field attracts the iron core to move, overcoming the spring force or other resistance, causing the valve core to move to a specific position, opening or closing the valve. When the electromagnetic coil is de-energized, the magnetic field disappears, and the spring force or other reset mechanism returns the valve core to its initial position, closing or opening the fluid channel.
[0003] When the solenoid coil is energized, the current flowing through it generates a magnetic field, which also causes the coil to heat up. For high-flow solenoid valves, prolonged operation can significantly increase the heat generated. This can cause the coil temperature to exceed 70°C, and in some cases, even reach over 90°C. High temperatures can affect the performance and lifespan of the solenoid valve and even cause the insulation to melt, leading to a coil short circuit. Summary of the Invention
[0004] In order to improve the heat dissipation effect of a large-flux solenoid valve, the present application provides a large-flux solenoid valve.
[0005] A large-flux solenoid valve provided in the present application adopts the following technical solution: a large-flux solenoid valve, comprising a valve body and an electromagnetic coil arranged in the valve body, a heat dissipation channel surrounding the electromagnetic coil is arranged on the outside of the valve body, a heat-conducting shell is arranged on the outside of the electromagnetic coil, the fins extend and are connected to the heat-conducting shell, fins connected to the heat-conducting shell are arranged in the heat dissipation channel, an air inlet channel is provided on one side of the heat dissipation channel, and an air outlet channel is provided at the other radial end of the heat dissipation channel.
[0006] By adopting the above technical solution, a heat-conducting shell is added to the outside of the electromagnetic coil, and the heat is conducted to the heat dissipation channel through the fins. The heat dissipation channel will surround and cooperate with the electromagnetic coil. After the air enters through the air inlet channel, the flowing gas contacts the fins, takes away the heat, and dissipates it through the air outlet channel, dissipating the heat in a timely and effective manner, thereby improving the heat dissipation effect.
[0007] Preferably, a plurality of fins are arranged at intervals in the heat dissipation channel along the extension direction, and the fins include a first fin arranged horizontally in the heat dissipation channel, a second fin arranged vertically below the first fin, and the second fin is arranged at intervals from the first fin.
[0008] Preferably, the first sheet is connected to the heat-conducting housing.
[0009] Preferably, the first pieces extend along the width direction of the heat dissipation channel, and the second pieces are arranged at intervals along the width direction of the heat dissipation channel.
[0010] By adopting the above technical solution, the heat on the peripheral side of the heat-conducting shell can be evenly transferred to the heat dissipation channel through multiple fins, and the second fin will be parallel to the gas flow direction to improve the heat dissipation effect.
[0011] Preferably, two air inlet channels are provided at intervals along the circumferential direction, the two air inlet channels respectively take in air toward both sides of the electromagnetic coil, and one air outlet channel is provided.
[0012] By adopting the above technical solution, the two air inlet channels will be ventilated from both sides respectively, which can avoid the gases from affecting each other.
[0013] Preferably, the heat dissipation channel has a linkage groove on the side away from the electromagnetic coil, the extended end of the first piece extends outward and protrudes from the linkage groove, the first piece has a deformation groove at one end close to the heat-conducting shell, and the deformation groove is located on the lower side of the first piece, and a support block is movably provided in the heat dissipation channel for contacting the lower side of the first piece.
[0014] By adopting the above technical solution, when dust accumulates on the second piece after long-term use, affecting heat dissipation, the support block can be moved downward to make the first piece lose its support. In the presence of the deformation groove and the second piece, the first piece will move downward. At this time, the gas flow will cause the first piece to shake and vibrate away the dust.
[0015] Preferably, a linkage ring is further provided on the outside of the heat dissipation channel, the upper surface of the linkage ring is lower than the lower side of the first piece, the upper wall of the linkage ring is provided with air holes corresponding to the first piece one by one, and gas is intermittently introduced into the linkage ring.
[0016] By adopting the above technical solution, the intermittent introduction of gas will cause the first piece to bend up and then fall down again and again to form a shaking effect, and when the support block hits the lower side of the first piece, the air holes have the effect of heat dissipation.
[0017] Preferably, an annular electromagnet for adsorbing the support block is installed on the inner side of the linkage ring, and a support spring is provided between the support block and the annular electromagnet.
[0018] Preferably, the portion of the first sheet located in the linkage groove has a blocking sheet, and the blocking sheet is used to prevent the gas in the pores from entering the heat dissipation channel.
[0019] By adopting the above technical solution, when the air holes act on the first sheet, the blocking sheet prevents the airflow from flowing into the heat dissipation channel, which can ideally make the first sheet vibrate.
[0020] To sum up, the present application includes at least one of the following beneficial technical effects: a heat-conducting shell is added to the outside of the electromagnetic coil, and the heat is conducted to the heat dissipation channel through the fins. The heat dissipation channel will surround the electromagnetic coil. After the air enters through the air inlet channel, the flowing gas will come into contact with the fins, take away the heat, and dissipate it through the air outlet channel, so that the heat is dissipated in a timely and better manner, thereby improving the heat dissipation effect.

DETAILED DESCRIPTION
[0023] The present application is further described in detail below with reference to the accompanying drawings.
[0024] The present application discloses a large flux solenoid valve, referring to Figure 1 、 Figure 2 The valve body 100 includes a valve body 100 and an electromagnetic coil disposed within the valve body 100. A heat-conducting housing 110 is provided on the outside of the electromagnetic coil. A heat dissipation channel 111 surrounding the electromagnetic coil is provided on the outside of the valve body 100. Fins are provided within the heat dissipation channel 111, which extend and connect to the heat-conducting housing 110. An air inlet channel 112 is provided on one side of the heat dissipation channel 111, and an air outlet channel 113 is provided at the other radial end of the heat dissipation channel 111.
[0025] In this embodiment, two air inlet channels 112 are provided at intervals along the circumference. The two air inlet channels 112 ventilate the heat dissipation channels 111 on either side, creating a two-half-ring air intake effect. The side with the air inlet channel 112 is the air inlet end, and the other radial side is the air outlet end. Only one air outlet channel 113 is provided corresponding to the air outlet.
[0026] In this embodiment, the fins include a first fin 120 and a second fin 121. The first fin 120 extends internally and is connected to the heat-conducting housing 110. The length of the first fin 120 is arranged along the width of the heat dissipation channel 111, while the second fin 121 is arranged on the lower side of the first fin 120. There are multiple second fins 121, and the multiple second fins 121 are arranged at intervals along the width of the heat dissipation channel 111. The second fins 121 will be parallel to the air flow direction to improve the heat dissipation effect.
[0027] The heat dissipation channel 111 has a linkage groove 122 on the side away from the electromagnetic coil. The linkage grooves 122 correspond one-to-one to the first piece 120. The extended end of the first piece 120 extends outward from the linkage groove 122. The end of the first piece 120 close to the heat-conducting shell 110 has a deformation groove 123. The deformation groove 123 is located on the lower side of the first piece 120 and at the end of the first piece 120 close to the heat-conducting shell 110. The deformation groove 123 is semicircular.
[0028] A linkage channel 124 is also provided on the outside of the heat dissipation channel 111. This channel 124 has a cavity within it, and its upper surface is lower than the underside of the first sheet 120. Air holes 125 are provided on its upper wall, corresponding one to one with the first sheet 120. These air holes 125 are located on the underside of the portion of the first sheet 120 that protrudes outward from the heat dissipation channel 111. The linkage channel 124 is located on one side of the air inlet channel 112, and a secondary air inlet channel 126 is provided between the two air inlet channels 112. Air is intermittently introduced into the secondary air inlet channel 126. Unlike the heat dissipation channel 111, the linkage channel 124 does not have a separate air outlet duct, but instead exhausts air solely through the air holes 125.
[0029] A support block 127 is movably provided within the heat dissipation channel 111 for contacting the lower side of the first plate 120. A blocking plate 130 is also provided below the first plate 120. Both the blocking plate 130 and the support block 127 are adapted to the width of the linkage slot 122. A sliding groove 131 is provided below the linkage slot 122 for the support block 127 to slide. The sliding groove 131 is vertically arranged. An annular electromagnet 132 for attracting the support block 127 is installed inside the linkage ring 124. A support spring 133 is provided between the support block 127 and the annular electromagnet 132. The end of the support spring 133 is supported by the annular electromagnet 132 and the support block 127. In the initial state, the support spring 133 causes the support block 127 to contact the lower side of the blocking plate 130, thereby closing the heat dissipation channel 111.
[0030] When the second piece 121 needs to be cleaned, the annular electromagnet 132 is first energized so that the support block 127 is attracted by the annular electromagnet 132. In this embodiment, the support block 127 can be adsorbed by the magnetic annular electromagnet 132, thereby overcoming the support spring 133. After the support block 127 moves downward, the first piece 120 loses its support. Due to the existence of the deformation groove 123, the outer end of the first piece 120 bends downward. At this time, air is intermittently taken in through the auxiliary air inlet duct 126, and air is discharged vertically upward in the air hole 125.
[0031] At this time, since the first piece 120 falls, the blocking piece 130 prevents the airflow in the air hole 125 from entering the heat dissipation channel 111, so that the first piece 120 moves upward and returns to a horizontal state. Then, as the airflow in the air hole 125 disappears, the first piece 120 falls again, thereby forming a vibration effect, which achieves the purpose of dust removal.
[0032] During normal heat dissipation, the annular electromagnet 132 loses its magnetism, and the support spring 133 returns to its original position, causing the support block 127 to turn the first piece 120 to a horizontal position for normal heat dissipation. At this time, air can continue to flow out of the auxiliary air inlet 126, dissipating heat from the end of the first piece 120 through the air holes 125, thereby accelerating the heat dissipation effect. Depending on the actual situation, a heat dissipation mode can be selected. The linkage ring 124 can be used to clean dust from the second piece 121, or it can assist the heat dissipation channel 111 in improving the heat dissipation effect during normal heat dissipation.
[0033] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
