Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to an automotive radiator with a leakage detection function. Background Technology

[0002] As a core component of the engine cooling system, the performance of the car radiator directly affects the engine's working efficiency and service life. According to statistics, about 32% of engine failures are caused by abnormalities in the cooling system, and radiator leakage is one of the main causes of cooling system failure.

[0003] When a traditional radiator leaks coolant, the driver often has to wait for the dashboard warning to detect it. By then, the leak may have already caused serious consequences such as engine overheating and cylinder block damage. This type of detection or discovery is relatively delayed.

[0004] Currently, in order to detect leaks in a timely manner, corresponding sensors and alarms are usually installed on car radiators. Once the sensor detects a leak, the alarm will sound, thus providing a more timely reminder to staff.

[0005] However, most car radiators with sensor detection still have some shortcomings in use. For example, they lack a component at the bottom to collect leaking liquid, causing the leaking liquid to drip directly onto other parts of the vehicle, affecting the stable operation of other components, especially electrical connections. Therefore, we propose a car radiator with leak detection functionality. Utility Model Content

[0006] The purpose of this invention is to provide an automotive radiator with a leakage detection function to address the deficiencies mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A car radiator with leakage detection function includes a car radiator frame and a heat dissipation flat tube mounted on the car radiator frame. Piezoresistive micro differential pressure sensors are fixedly installed on both ends of the heat dissipation flat tube. A data processing host is installed outside the car radiator frame. A liquid collection cover is detachably installed at the bottom of the car radiator frame. A collection chamber is provided inside the liquid collection cover. A vertical tube is fixedly installed at the bottom end of the liquid collection cover, and a threaded cap is threaded onto the vertical tube. Multiple leakage holes communicating with the collection chamber are provided on the bottom plate of the car radiator frame.

[0009] Preferably, both ends of the heat dissipation flat tube are fixedly installed with a fixing joint, and the fixing joint is connected to the pipe on the vehicle's heat dissipation system.

[0010] Preferably, frame mounting seats are fixedly installed on both ends of the car radiator frame, and the frame mounting seats are fixedly installed on the car frame.

[0011] Preferably, side splash guards are fixedly installed at both ends of the car radiator frame, and the side splash guards are hollow structures;

[0012] The side splash guards in this feature can prevent internal liquids from splashing outwards from both sides.

[0013] Preferably, the top wall of the leakage hole is provided with a flared hole, which is funnel-shaped;

[0014] This feature allows leaking coolant to drip down more smoothly through the flared orifice.

[0015] Preferably, an alarm is fixedly installed on the data processing host, and both the data processing host and the alarm are powered by the vehicle power supply.

[0016] Preferably, side fixing plates are fixedly installed at both ends of the liquid collection cover, and the side fixing plates are detachably installed on the bottom surface of the car radiator frame by multiple fastening screws;

[0017] This feature facilitates the installation and removal of the liquid collection hood.

[0018] Preferably, a sealing gasket is fixedly installed on the inner wall of the threaded cap, and anti-slip stripes are provided on the outer annular side of the threaded cap.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model achieves the collection and real-time detection of leaking coolant by installing a detachable liquid collection cover at the bottom of the car radiator frame and installing piezoresistive micro differential pressure sensors at both ends of the heat dissipation flat tube. The piezoresistive micro differential pressure sensor can detect the pressure change inside the heat dissipation flat tube in a timely manner. After receiving the signal, the data processing host drives the alarm to sound. The liquid collection cover collects the leaking liquid through the leakage hole to prevent it from dripping onto other parts of the car and ensure the stable operation of other parts inside the car.

[0021] 2. This utility model achieves smooth guidance, splash prevention, and convenient discharge of leaking liquid by setting a funnel-shaped flared hole at the top of the leakage hole, installing a side splash guard on the side, and setting a threaded cap with a sealing gasket at the bottom of the collection shroud. The flared hole allows the coolant to flow smoothly into the collection shroud, the side splash guard prevents liquid from splashing, the threaded cap and sealing gasket ensure the sealing of the collection shroud, and unscrewing the threaded cap allows for easy discharge of the collected coolant, improving the convenience of use.

[0022] 3. This utility model achieves stable installation of the radiator and convenient installation and removal of the liquid collection cover by setting frame mounting seats at both ends of the car radiator frame and side fixing plates at both ends of the liquid collection cover. The frame mounting seats fix the radiator to the car frame, and the side fixing plates are fastened with screws to firmly connect the liquid collection cover to the radiator frame, which facilitates the removal of the liquid collection cover for cleaning and maintenance, and ensures long-term reliable operation of the radiator.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-5This utility model provides a technical solution: a car radiator with leakage detection function, including a car radiator frame 1 and a heat dissipation flat tube 10 disposed on the car radiator frame 1. Piezoresistive micro differential pressure sensors 14 are fixedly installed on both ends of the heat dissipation flat tube 10. A data processing host 2 is disposed outside the car radiator frame 1, so that the piezoresistive micro differential pressure sensors 14 can monitor the pressure changes inside the heat dissipation flat tube 10 in real time, and transmit the data to the data processing host 2 for analysis, so as to realize the real-time detection of radiator leakage, timely detection of leakage, and avoid serious consequences such as engine overheating due to delayed leakage detection.

[0034] In this embodiment, a liquid collection cover 3 is detachably installed at the bottom of the car radiator frame 1. A collection chamber 30 is provided inside the liquid collection cover 3. A vertical pipe 32 is fixedly installed at the bottom end of the liquid collection cover 3, and a threaded cap 33 is threadedly connected to the vertical pipe 32. A plurality of leakage holes 15 connected to the collection chamber 30 are provided on the bottom plate of the car radiator frame 1, so that the leaked coolant flows into the collection chamber 30 through the leakage holes 15 and is collected by the liquid collection cover 3, preventing the coolant from dripping directly onto other parts of the car and avoiding affecting the stable operation of other parts, especially the circuit connection parts.

[0035] like Figure 1 As shown, both ends of the heat dissipation flat tube 10 are fixedly installed with a fixing connector 11. The fixing connector 11 is connected to the pipe on the vehicle's heat dissipation system to ensure a stable connection between the heat dissipation flat tube 10 and the vehicle's heat dissipation system, to ensure normal flow of coolant, and to maintain the heat dissipation function of the radiator.

[0036] like Figure 1 As shown, frame mounting bases 12 are fixedly installed on both ends of the car radiator frame 1. The frame mounting bases 12 are fixedly installed on the car frame to ensure the stability of the radiator installation and prevent it from loosening or falling off during car operation.

[0037] like Figure 1 As shown, side splash guards 13 are fixedly installed at both ends of the car radiator frame 1. The side splash guards 13 are hollow structures, which prevent the liquid inside the radiator from splashing outward from both sides, thus avoiding the splashed liquid from affecting other parts of the car or causing safety hazards.

[0038] like Figure 3 As shown, a flared hole 151 is provided on the top wall of the leakage hole 15. The flared hole 151 is funnel-shaped, which allows the leaked coolant to drip more smoothly into the collection chamber 30 of the liquid collection cover 3, thereby improving the coolant collection efficiency and preventing the leakage hole 15 from becoming blocked.

[0039] Specifically, an alarm 20 is fixedly installed on the data processing host 2. Both the data processing host 2 and the alarm 20 are powered by the vehicle power supply. After the data processing host 2 detects a leakage signal, it drives the alarm 20 to sound an alarm, so as to promptly remind the staff to deal with the leakage problem quickly.

[0040] Furthermore, side fixing plates 31 are fixedly installed at both ends of the liquid collection cover 3. The side fixing plates 31 are detachably installed on the bottom surface of the car radiator frame 1 by multiple fastening screws, making the liquid collection cover 3 easy to install and remove, and facilitating the cleaning, maintenance or replacement of the liquid collection cover 3 by the staff, so as to ensure the normal functioning of the liquid collection function.

[0041] like Figure 5 As shown, a sealing gasket 331 is fixedly installed on the inner wall of the threaded cover 33, and anti-slip stripes 332 are provided on the outer annular side of the threaded cover 33. The sealing gasket 331 enhances the sealing performance of the connection between the threaded cover 33 and the vertical pipe 32, preventing the coolant in the collection chamber 30 from leaking. The anti-slip stripes 332 make it easy for the operator to unscrew the threaded cover 33 and facilitate the discharge of the collected coolant.

[0042] It is worth noting that when the heat dissipation flat tube 10 leaks, the piezoresistive micro differential pressure sensor 14 monitors the pressure inside the heat dissipation flat tube 10 in real time. When the data processing host 2 detects that the pressure has dropped and the preset alarm conditions are met, the data processing host 2 controls the alarm 20 to trigger an alarm.

[0043] Finally, it should be noted that the piezoresistive micro differential pressure sensor 14, data processing host 2, vehicle power supply, corresponding control system and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0044] When using the car radiator with leakage detection function of this utility model, first fix the car radiator frame 1 to the car frame through the frame mounting base 12 to ensure that the installation is stable. Then connect the fixing joints 11 at both ends of the heat dissipation flat tube 10 to the car heat dissipation system pipe to ensure normal flow of coolant. Then install the liquid collection cover 3 at the bottom of the car radiator frame 1 through the side fixing plate 31 and fastening screws to make the leakage hole 15 communicate with the collection chamber 30.

[0045] The piezoresistive micro differential pressure sensor 14 monitors the pressure change inside the heat dissipation flat tube 10 in real time and transmits the data to the data processing host 2 for analysis. If the heat dissipation flat tube 10 leaks and causes abnormal pressure, the data processing host 2 drives the alarm 20 to issue an alarm to remind the staff. At the same time, the leaked coolant flows into the collection chamber 30 of the liquid collection cover 3 through the leakage hole 15 and the flared hole 151 to prevent it from dripping onto other parts of the car.

[0046] When it is necessary to drain the collected coolant, unscrew the anti-slip stripe 332 on the threaded cap 33 to open the threaded cap 33 and drain the coolant through the vertical pipe 32. After cleaning, replace the threaded cap 33 and ensure a seal using the sealing gasket 331.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
