Description

Technical Field

[0001] The utility model belongs to the technical field of power supply protection equipment, and in particular relates to an ion pump power supply over-temperature protection device. Background Art

[0002] A power supply overtemperature protection device is a protective device used to prevent power supply equipment from being damaged due to excessive temperatures during operation. It can be used in various power supply systems, such as ion pumps, chargers, adapters, and built-in power supplies of electronic devices. These devices may experience temperature rises during operation due to overload, poor heat dissipation, or excessively high ambient temperatures. If not controlled, these rises may cause equipment failures or even fires and other safety accidents. The power supply overtemperature protection device is designed to prevent this from happening.

[0003] A Chinese patent with patent publication number CN221652887U discloses a power supply overtemperature protection device, including a lower housing, an upper housing fixedly provided on the top of the lower housing, a heat sink fixedly provided on the top of the lower housing, and by installing the lower housing, it is fixedly connected to the upper housing when in use, thereby protecting the internal structure of the entire device. The heat sink is installed, and when the temperature is too high, it plays a role in rapid heat dissipation. The copper plate is installed, and when in use, the internal temperature is too high, which will cause the power supply to automatically short-circuit, and when the temperature returns to normal, the circuit can operate normally, thereby protecting the power supply. However, the heat dissipation effect of the device through the heat sink and the heat dissipation holes alone is not obvious. When the power supply temperature is too high, it cannot dissipate heat in time, which can easily cause damage to the power supply.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an ion pump power supply over-temperature protection device, thereby solving the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] An ion pump power supply overtemperature protection device comprises: a box body, a box cover detachably connected to the top thereof, a mounting slot for mounting the power supply body formed by heat conducting plates and fixing plates arranged opposite each other in pairs within the box body, a plurality of relatively staggered partitions fixedly connected between the fixing plates and the box body, the plurality of partitions forming a serpentine channel between the box body and the fixing plates, and through holes communicating with the mounting slots being provided through the fixing plates between adjacent partitions;

[0008] A heat dissipation fan is fixedly connected to the box body, with an air outlet of the heat dissipation fan facing the serpentine channel formed between the partition plate and the fixed plate, and first heat dissipation holes are provided at both ends of the box body.

[0013] Optionally, an alarm is fixedly connected to the box body and is connected to the controller signal.

[0014] Optionally, a support plate is fixedly connected to the bottom of the box body.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0016] 1. The heat dissipation fan, partition and through-hole are provided. When the heat dissipation fan is working, air enters from the first heat dissipation holes at both ends of the box body, is accelerated by the heat dissipation fan and flows in the serpentine channel. The heat flow generated by the power supply body is taken away through the through-hole to achieve heat dissipation and prevent the power supply body from being overheated. The heat dissipation efficiency of the power supply body is greatly improved, and the disassembly and maintenance of the power supply body are facilitated.

[0017] 2. The heat dissipation fins expand the contact area between the box and the outside air, helping to dissipate the heat inside the box to the surrounding environment more quickly, further reducing the temperature of the power supply and ensuring stable operation of the power supply;

[0018] 3. By setting up a temperature sensor, a controller and an alarm, the temperature inside the box is monitored in real time by the temperature sensor and the signal is transmitted to the controller. The controller controls the speed and opening and closing of the cooling fan according to the preset temperature threshold, and the alarm serves as an early warning.

DETAILED DESCRIPTION

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] See also Figure 1-6As shown, in this embodiment, an ion pump power supply overtemperature protection device is provided, including a box body 1, a box cover 4 is detachably connected to the top of the box body 1, a mounting groove 13 for mounting the power supply body 7 is formed by heat conducting plates 8 and fixed plates 12 arranged opposite to each other in pairs, a plurality of relatively staggered partitions 11 are fixedly connected between the fixed plates 12 and the box body 1, and the plurality of partitions 11 form a serpentine channel between the box body 1 and the fixed plates 12, and a through hole 17 connected to the mounting groove 13 is penetrated on the fixed plates 12 between adjacent partitions 11, and a cooling fan 10 is fixedly connected in the box body 1, and the air outlet of the cooling fan 10 faces the serpentine channel formed between the partitions 11 and the fixed plates 12, and a first cooling hole 3 is penetrated at both ends of the box body 1.

[0032] Specifically, the power supply body 7 is installed in the installation groove 13 formed by the heat conducting plate 8 and the fixing plate 12. The power supply body 7 generates heat during operation. The heat is first transferred to the heat conducting plate 8 and the fixing plate 12 through heat conduction, and then transferred to the box body 1 for heat dissipation. The material of the box body 1 can be a heat-conducting material, such as aluminum alloy. The heat dissipation fan 10 blows air to the serpentine channel between the partition 11 and the fixing plate 12, and the air enters the box body 1 from the first heat dissipation hole 3. Under the action of the heat dissipation fan 10, the air flows in the serpentine channel. Since there is a through hole 17 connected to the installation groove 13 on the fixing plate 12, the heat generated by the power supply body 7 in the installation groove 13 can be transferred to the air flowing in the serpentine channel through the through hole 17. The air continuously absorbs heat when flowing in the serpentine channel, and then is discharged from the first heat dissipation hole 3 at the other end of the box body 1 with the heat, thereby realizing heat dissipation of the power supply body 7 and preventing the power supply body 7 from being too hot. The overall structure is simple to install, which greatly improves the heat dissipation efficiency of the power supply body 7 and facilitates the disassembly and maintenance of the power supply body 7.

[0033] It should be noted that, in this embodiment, the fixed plate 12 and the heat conducting plate 8 are both two pieces, and are arranged opposite to each other in pairs. The two heat conducting plates 8 and the two fixed plates 12 form a semi-enclosed structure, that is, forming an installation groove 13. The fixed plate 12 and the heat conducting plate 8 are both made of heat-conducting materials, preferably aluminum alloy, and the control method of the cooling fan 10 is the existing technology.

[0034] In this embodiment, if Figure 2 As shown, a plurality of heat dissipation fins 6 are fixedly connected to the bottom of the box body 1. Specifically, when the heat of the heat conducting plate 8 and the fixing plate 12 is discharged to the bottom of the box body 1, the heat is dissipated through the heat dissipation fins 6 and the surrounding air for heat exchange. The heat dissipation fins 6 expand the contact area between the box body 1 and the external air, which helps to dissipate the heat in the box body 1 to the surrounding environment faster, further reduce the temperature of the power supply body 7, and ensure the stable operation of the power supply body 7.

[0035] In this embodiment, if Figure 3 and Figure 4 As shown, the heat conducting plate 8 is provided with a plurality of third heat dissipation holes 9 relative to the first heat dissipation holes 3. Specifically, when the cooling fan 10 is working, air can flow on both sides of the heat conducting plate 8 through the third heat dissipation holes 9, helping to take away the heat on the heat conducting plate 8. At the same time, it also helps to balance the air pressure in the box body 1 and improve the heat dissipation effect of the power supply body 7.

[0036] In this embodiment, if Figure 1 As shown, a plurality of second heat dissipation holes 5 are provided on the box cover 4 facing the mounting groove 13. Specifically, the plurality of second heat dissipation holes 5 on the box cover 4 facing the mounting groove 13 provide another heat dissipation channel for the hot air in the box body 1. A part of the heat generated by the power supply body 7 is discharged from the second heat dissipation holes 5 through air convection, which increases the discharge path of the hot air and enables the heat in the box body 1 to be dissipated more quickly. This works together with other heat dissipation measures to improve the overall heat dissipation performance.

[0037] In this embodiment, if Figure 4 and Figure 5 As shown, a temperature sensor 15 is fixedly connected to the box body 1, and a controller 14 is fixedly connected to the box body 1, which is connected to the cooling fan 10 and the temperature sensor 15 by signal. Specifically, the temperature sensor 15 monitors the temperature in the box body 1 in real time and transmits the signal to the controller 14. The controller 14 controls the speed and opening and closing of the cooling fan 10 according to a preset temperature threshold. When the temperature rises to a certain level, the controller 14 increases the speed of the cooling fan 10 to enhance heat dissipation; when the temperature drops to an appropriate range, the speed of the cooling fan 10 can be appropriately reduced or the operation of the cooling fan 10 can be stopped, thereby realizing automatic opening and closing of the cooling fan 10.

[0038] In this embodiment, if Figure 4 and Figure 5 As shown, an alarm 16 connected to the controller 14 signal is fixedly connected in the box body 1. Specifically, when the temperature detected by the temperature sensor 15 exceeds the alarm threshold preset by the controller 14, the controller 14 triggers the alarm 16 to send an alarm signal, which can promptly inform the operator of the abnormal situation that the temperature of the power supply body 7 is too high, so that the operator can take corresponding measures, such as checking whether the power supply body 7 is overloaded, whether the cooling system is faulty, etc., to prevent the power supply body 7 from being damaged due to overheating; It should be noted that in another embodiment, a power protection device can be installed in the box body 1. When the temperature reaches the threshold, the protection device will cut off the power supply circuit of the power supply device through the switching elements in the control circuit, such as relays, transistors, etc., so that the power supply device stops working, thereby preventing the temperature from continuing to rise. For example, in some simple over-temperature protection circuits, when the temperature sensor 15 detects a high temperature signal, it will trigger the relay to act, and the contacts of the relay will be disconnected, thereby cutting off the power input, thereby protecting the power supply device.

[0039] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, a support plate 2 is fixedly connected to the bottom of the box body 1. Specifically, the support plate 2 at the bottom of the box body 1 is used to support the entire ion pump power supply body 7 over-temperature protection device, so that the device has a certain distance from the installation plane, ensuring the normal circulation of air around the bottom heat dissipation fins 6, and also providing a stable placement foundation for the device.

[0040] Working principle:

[0041] The power supply body 7 is installed in the mounting groove 13 formed by the heat conducting plate 8 and the fixing plate 12. The power supply body 7 generates heat during operation. The heat is first transferred to the heat conducting plate 8 and the fixing plate 12 through heat conduction, and then transferred to the box body 1 for heat dissipation. The material of the box body 1 can be a heat-conducting material, such as aluminum alloy. The heat dissipation fan 10 blows air to the serpentine channel between the partition 11 and the fixing plate 12, and the air enters the box body 1 from the first heat dissipation hole 3. Under the action of the heat dissipation fan 10, the air flows in the serpentine channel. Since there is a through hole 17 connected to the mounting groove 13 on the fixing plate 12, the heat generated by the power supply body 7 in the mounting groove 13 can be transferred to the air flowing in the serpentine channel through the through hole 17. The air continuously absorbs heat when flowing in the serpentine channel, and then is discharged from the first heat dissipation hole 3 at the other end of the box body 1 with the heat, thereby realizing heat dissipation of the power supply body 7 and preventing the power supply body 7 from being too hot. The overall structure is simple to install, which greatly improves the heat dissipation efficiency of the power supply body 7 and facilitates the disassembly and maintenance of the power supply body 7.
