Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation devices, and more particularly to a liquid leakage protection device for a radiator. Background Art

[0002] At present, some electronic components or modules such as certain pulse power supplies and controllers often generate a large amount of heat during operation and require a heat dissipation device to be configured. Among them, radiators that use a coolant for circulating cooling are widely used, which have good heat dissipation efficiency and do not bring too many interfering factors to the working environment.

[0003] Due to reasons such as heat dissipation and processing technology of electronic components such as pulse power supplies, some modules will cause the radiator supporting the module to be electrified during operation. For example, when the pulse power supply is operating, the radiator will carry a high voltage of tens of thousands of volts. Although the coolant joint between the radiator and the coolant circulation pipeline has a sealing and insulating structure, due to the complex working environment, in case of coolant leakage that cannot be detected, serious consequences will occur. Summary of the Invention

[0004] The purpose of the present invention is to provide a liquid leakage protection device for a radiator to solve at least one of the above technical problems existing in the prior art.

[0005] To solve the above technical problems, a liquid leakage protection device for a radiator provided by the present invention includes: a liquid leakage collector and a drainage device;

[0006] The liquid leakage collector includes a housing; the housing is sleeved outside the coolant joint of the radiator and is used to receive the coolant leaking from the joint.

[0007] A liquid discharge port is provided at the bottom of the housing, and the drainage device is connected to the liquid discharge port and is used to receive and drain or store the coolant flowing out of the housing.

[0008] By sleeving the housing of the liquid leakage collector outside the coolant joint of the radiator, the present invention can timely collect the leaked coolant, avoid the coolant from splashing, thereby avoiding damage to the radiator and the surrounding electronic components, and preventing accidents such as short circuits.

[0009] Further, it further includes a liquid leakage sensor for monitoring whether coolant leakage occurs.

[0010] Further, it further includes a controller and an alarm device, and the controller is communicatively connected to the alarm device and the liquid leakage sensor respectively. When the liquid leakage sensor detects coolant leakage, an alarm message is sent through the alarm device.

[0011] Preferably, the controller is connected to the power supply of the radiator, and when the liquid leakage sensor detects coolant leakage, the controller shuts off the power supply.

[0012] Further, the drainage device includes a collection cover. In the height direction, the collection cover is arranged below the housing, and the coolant in the housing directly drops or flows into the collection cover through a drainage pipeline through a drain port.

[0013] The radiator may include a plurality of coolant pipelines, correspondingly including a plurality of joints. A liquid leakage collector housing is sleeved on each joint. The collection cover can collect the coolant collected by the plurality of housings in one place, which is convenient for monitoring.

[0014] When a certain joint fails to be arranged directly above the collection cover, a drainage pipeline can be used to guide the leaked coolant into the collection cover.

[0015] Further, the flow channel in the collection cover is inclined to collect the coolant in the collection cover in one place.

[0016] Further, the slope of the flow channel is 5 - 30°.

[0017] Further, the collection cover is made of an insulating material. More preferably, the collection cover is made of an insulating and hydrophobic material, such as PTFE; or, the surface of the flow channel is coated with a hydrophobic coating.

[0018] Further, the inner side surface of the housing is coated with a hydrophobic coating, or the housing is made of a hydrophobic material.

[0019] The hydrophobicity of the housing and the flow channel of the collection cover can accelerate the flow of the coolant and improve the sensitivity of the entire system to liquid leakage detection.

[0020] Further, the probe of the liquid leakage sensor is arranged at the coolant collection part in the collection cover.

[0021] The collection cover serves as a temporary storage component for the coolant. When coolant leaks from any one of the joints, the leaked coolant will flow into the collection part through the flow channel in the collection cover. The liquid leakage sensor senses it immediately and sends out an alarm message through the controller. The form of the alarm message is diverse, such as text messages, various forms of warnings such as sound, light, and electricity.

[0022] Among them, the form of the drainage device is not limited to the above-mentioned collection cover. The drainage device can also be a delivery pipe, which includes branch pipes and a main pipe. The inlets of several branch pipes are respectively connected to the drain ports of several of the housings, and the outlets of several branch pipes are connected to the inlet of the main pipe. The main pipe is used to collect the leaked coolant and export the coolant.

[0023] Preferably, the outlet of the main pipe can be arranged outside the working environment of the radiator; when the coolant is water, the main pipe can directly lead the water out of the working environment of the radiator for natural evaporation, or use containers such as barrels or boxes for collection.

[0024] Furthermore, the probe of the liquid leakage sensor is arranged in the main pipe.

[0025] Furthermore, the collection cover is annular. The collection cover is sleeved on the radiator, and an annular groove is formed between the collection cover and the outer circular side surface of the radiator; the annular groove is inclined (at an angle of 5 - 30° with the horizontal), the bottom surface of the annular groove includes a highest point and a lowest point, and two flow channels connecting the highest point and the lowest point are formed on both sides of the radiator in the annular groove; the lowest point of the bottom surface of the annular groove is the part where the coolant in the collection cover converges.

[0026] Furthermore, a sealing structure is arranged between the collection cover and the outer circular side surface of the radiator. There are many forms of the sealing structure, such as sealing rings, etc.

[0027] Preferably, a clamping groove is arranged on one side of the outer circular side surface of the radiator at the bottom of the collection cover, and the cross-section of the clamping groove is wedge-shaped; a sealing ring is arranged in the clamping groove;

[0028] A locking ring (or called a locking nut) is further included. The locking ring is screwed on the bottom of the collection cover by a threaded manner. Tightening the locking ring reduces the cross-sectional area of the clamping groove, and then the sealing ring is forced to closely adhere to the outer circular side surface of the radiator by extrusion.

[0029] While achieving sealing by tightening the locking ring, it can also play a role in fixing the collection cover.

[0030] Adopting the above technical solutions, the present invention has the following beneficial effects:

[0031] A liquid leakage protection device for a radiator provided by the present invention has a simple structure. The leaked coolant is collected through the water collection structure, avoiding the wanton flow of the coolant, thereby effectively preventing the coolant from corroding materials, such as damaging the surface insulation coating of electronic components and preventing accidents such as short circuits.

[0032] Moreover, by setting the liquid leakage sensor, the liquid leakage can be monitored in real time, and instant alarm or power cut-off can be realized to avoid greater damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following further explains and illustrates the present invention in combination with specific embodiments.

[0048] Embodiment 1

[0049] Figure 1 is a schematic structural diagram of the radiator leak liquid protection device provided for this embodiment; Figure 2 is Figure 1 an exploded view of the radiator leak liquid protection device shown.

[0050] As Figure 1-2 shown, a radiator leak liquid protection device provided in this embodiment includes: a leak liquid collector 10 and a drainage device.

[0051] The leak liquid collector 10 includes a housing 11; as Figure 5 shown, the housing 11 is sleeved outside the coolant joint 101 of the radiator 100 and is used to receive the coolant leaking from the joint 101.

[0052] Preferably, the housing 11 is formed by two half-housings through a snap connection method, so as to facilitate sleeving the joint 101.

[0053] A drain port 11a is provided at the bottom of the housing 11, and the drainage device is connected to the drain port 11a and is used to receive, drain, or store the coolant flowing out of the housing 11.

[0054] In the present invention, by sleeving the housing 11 of the liquid leakage collector 10 on the coolant connector 101 outside the radiator 100, the leaked coolant can be collected in a timely manner, preventing the coolant from splashing, thus avoiding damage to the radiator 100 and the electronic components around it, and preventing accidents such as short circuits.

[0055] More preferably in the above technical solution, this embodiment further includes a liquid leakage sensor 30, a controller (not shown), and an alarm device (not shown) for monitoring whether coolant leakage occurs. The controller is communicatively connected to the alarm device and the liquid leakage sensor 30 respectively. When the liquid leakage sensor 30 detects coolant leakage, an alarm message is sent through the alarm device. Further preferably, the controller can also be connected to the power supply of the radiator 100. When the liquid leakage sensor 30 detects coolant leakage, the controller shuts off the power supply.

[0056] The drainage device in this embodiment includes a collection cover 20. In the height direction, the collection cover 20 is arranged below the housing 11, and the coolant in the housing 11 directly drips into or flows into the collection cover 20 through a drainage pipeline 12 through a drainage port 11a.

[0057] In this embodiment, some connectors 101 are arranged outside the radiator 100 and above the collection cover 20. If liquid leakage occurs in the connectors 101, after being collected by the housing 11, the leaked liquid can directly drip into the collection cover 20 through the drainage port 11a below the housing 11. And some connectors 101 are arranged above the radiator 100, and it is necessary to use the drainage pipeline 12 to guide the leaked liquid collected by the housing 11 into the collection cover 20. The form of the drainage pipeline 12 can be set according to the drainage needs. It can be an integrally arranged flexible pipeline that bypasses the radiator 100 or other electronic components and then drains the leaked liquid into the collection cover 20; or, as Figure 1 and Figure 2 shown, the drainage pipeline 12 is arranged in a split manner and at least includes a collection base 12a for sealing connection with the bottom of the housing 11. A collection cavity with an upper opening communicating with the drainage port 11a of the housing 11 is arranged in the collection base 12a. A drainage groove 12b is arranged on one side of the collection base 12a for draining the leaked liquid from the top of the radiator 100 to the outside of the radiator 100 and above the collection cover 20. At this time, the leaked liquid can directly drip into the collection cover 20, or as Figure 2 shown, a vertical pipe 12c communicating with the outlet of the drainage groove 12b is used to transport the leaked liquid into the collection cover 20.

[0058] In this embodiment, the radiator 100 includes four coolant pipelines, corresponding to four connectors 101. A housing 11 of the liquid leakage collector 10 is sleeved on each connector 101. The collecting cover 20 can collect the coolant collected by the four housings 11 in one place for easy monitoring.

[0059] Among them, two connectors 101 are arranged on the outer circumferential side surface of the radiator 100, just above the collecting cover 20. The liquid discharge port 11a at the bottom of the housing 11 is directly opposite to the flow channel 21 in the collecting cover 20, and the leaked coolant can directly drip into the collecting cover 20 through the liquid discharge port 11a. To prevent the dripping coolant from splashing out, the collecting cover 20 is as close as possible to the liquid discharge port 11a. The other two connectors 101 are arranged on the top of the radiator 100, and the flow channel 21 is used to guide the leaked coolant into the collecting cover 20.

[0060] Figure 3 It is a schematic structural diagram of the collecting cover in Embodiment 1; Figure 4 It is a schematic structural diagram of the inclined flow channel in the collecting cover in Embodiment 1; More preferably, as Figure 3 and Figure 4 shown, the flow channel 21 in the collecting cover 20 is inclined to collect the coolant in the collecting cover 20 in one place. Among them, the slope of the flow channel 21 is preferably 5 - 30°.

[0061] In this embodiment, as Figure 3 shown, the collecting cover 20 is a whole annular structure, and the collecting cover 20 is sleeved on the radiator 100; in terms of the cross-section of the collecting cover 20, the collecting cover 20 includes an integrally formed inner baffle, outer baffle and bottom plate; the inner baffle, outer baffle and bottom plate enclose an annular groove for draining and collecting the leaked liquid. Or, the collecting cover 20 does not have an inner baffle, or the inner baffle is set lower, and an annular groove is formed between the collecting cover 20 and the outer circumferential side surface of the radiator 100; the annular groove is inclined at an angle of 5 - 30° with the horizontal, there is a highest point 20a at one end of the bottom surface of the annular groove, and a lowest point 20b at the other end, and two flow channels 21 connecting the highest point 20a and the lowest point 20b are formed on both sides of the radiator 100 in the annular groove; that is, the collected coolant can be respectively collected at the lowest point 20b of the bottom surface of the annular groove through the flow channels 21 on both sides, and the lowest point 20b of the annular groove is the part where the coolant in the collecting cover 20 is collected.

[0062] Among them, the probe 31 of the liquid leakage sensor 30 is arranged at the part where the coolant in the collecting cover 20 is collected.

[0063] The collection cover 20 serves as a temporary storage component for the coolant. When coolant leakage occurs at any one of the joints 101, the leaked coolant will flow into the collection area through the flow channel 21 inside the collection cover 20. Once the liquid leakage sensor 30 senses it, an alarm message will be sent outwards through the controller. The forms of the alarm message are diverse, such as text messages, various forms of warnings like sound, light, and electricity.

[0064] Preferably, the collection cover 20 is made of insulating material. More preferably, the collection cover 20 is made of insulating and hydrophobic material, such as PTFE; or, only the surface of the flow channel 21 is coated with a hydrophobic coating. Also, the inner surface of the housing 11 is coated with a hydrophobic coating, or the housing 11 is made of hydrophobic material.

[0065] The hydrophobicity of the housing 11 and the flow channel 21 of the collection cover 20 can accelerate the flow of the coolant and improve the sensitivity of the entire system to liquid leakage detection.

[0066] A sealing structure is provided between the collection cover 20 and the outer circumferential side surface of the radiator 100. There are many forms of the sealing structure, such as a sealing gasket.

[0067] Figure 6 It is an exploded view of the bottom sealing structure of the collection cover in Embodiment 1; Figure 7 It is a partial cross-sectional view of the bottom sealing structure of the collection cover in Embodiment 1. As a preferred implementation method, as Figure 4 、 6 and Figure 7 shown, a clamping groove 22 is provided on one side of the outer circumferential side surface of the radiator 100 at the bottom of the collection cover 20. The cross-section of the clamping groove 22 is wedge-shaped; a sealing ring 26 is arranged in the clamping groove 22.

[0068] A locking ring 25 (or called a locking nut) is provided at the bottom of the collection cover 20. The locking ring 25 is screwed onto the bottom of the collection cover by a threaded method. During the process of tightening the locking ring 25, the locking ring squeezes the clamping groove 22, making its cross-sectional area smaller, and then forcing the sealing ring 26 to deform towards the outer circumferential side surface of the radiator 100 through extrusion, and then tightly adhering to the outer circumferential side surface of the radiator 100. While achieving sealing by tightening the locking ring, it can also play a role in fixing the collection cover 20.

[0069] A radiator liquid leakage protection device provided by the present invention has a simple structure. It collects the leaked coolant through the water collection structure, avoiding the wanton flow of the coolant, thereby effectively preventing the coolant from corroding materials, such as damaging the surface insulation coating of electronic components and preventing accidents such as short circuits. Also, by setting the liquid leakage sensor 30, the liquid leakage can be monitored in real time to achieve instant alarm or cut off the power supply to avoid greater damage.

[0070] Embodiment 2

[0071] This embodiment is basically the same as Embodiment 1, except that:

[0072] Among them, the form of the drainage device is not limited to the above-mentioned collection hood 20. For example Figure 8 As shown, the drainage device can also be a delivery pipe 40. The delivery pipe 40 includes branch pipes 41 and a main pipe 42. The inlets of the 3 branch pipes 41 are respectively connected to the liquid discharge ports 11a of the 3 housings 11, and the outlets of the 3 branch pipes 41 are connected to the inlet of the main pipe 42 through a four-way joint 43. The main pipe 42 is used to collect the leaked coolant and export the coolant.

[0073] Preferably, the outlet of the main pipe 42 can be arranged outside the working environment of the radiator 100; when the coolant is water, the main pipe 42 can directly export the water outside the working environment of the radiator 100 to make it evaporate naturally, or use containers such as buckets and boxes for collection. The probe 31 of the liquid leakage sensor 30 is arranged in the main pipe 42.

[0074] This embodiment can export the coolant outside the working environment of the radiator through the delivery pipe 40, avoid the continuous evaporation of the coolant, and control the humidity of the working environment of the electronic components.

[0075] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
