Description

Technical Field

[0001] This utility model relates to the field of automotive antifreeze technology, specifically to a heating device for automotive antifreeze. Background Technology

[0002] Automotive antifreeze is a liquid specifically designed for use in automotive cooling systems. Its main function is to prevent the engine from freezing at low temperatures and boiling at high temperatures, thereby protecting the engine and ensuring its normal operation. The main components of antifreeze include ethylene glycol, water, antifreeze agents, coolants, corrosion inhibitors, and scale inhibitors.

[0003] Existing antifreeze heating devices utilize a circulating pump to extract and circulate the antifreeze, with a heater installed inside the external circulation pipe to heat the circulating antifreeze. However, these devices typically heat the antifreeze only once, resulting in short heating time and a small contact area between the heating device and the antifreeze, leading to less than ideal heating performance. Therefore, this paper proposes a heating device for automotive antifreeze that uses a double-layer heating chamber to increase heating time and the contact area between the heating device and the antifreeze, thereby improving heating efficiency. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a heating device for automotive antifreeze, which can increase the heating time and the contact area between the heating device and the antifreeze by setting up a double-layer heating chamber, thereby improving the heating effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is a heating device for automotive antifreeze, including an outer heating shell and an inner heating shell. The inner heating shell is fixedly installed inside the outer heating shell. One end of the inner heating shell is fixedly connected to the inner end of the outer heating shell. A second heating chamber is opened inside the inner heating shell, and a first heating chamber is opened inside the outer heating shell. A connecting hole is opened at one end of the inner heating shell. There are multiple connecting holes. The first heating chamber is connected to the second heating chamber through the multiple connecting holes.

[0006] The inner heating shell has a second coil mounting cavity inside, which is used for the fixed installation of the second heating coil. The outer heating shell is fitted with a heat insulation shell, and a first coil mounting cavity is formed between the heat insulation shell and the outer heating shell. The first coil mounting cavity is used for the fixed installation of the first heating coil.

[0007] By adopting the above technical solution, the setting of the outer heating shell and the inner heating shell allows the antifreeze to come into contact with a relatively large heating area in the first heating chamber, and allows the antifreeze to flow into the second heating chamber through the connecting hole, thereby increasing the heating time and improving the heating effect of the antifreeze.

[0008] Specifically, one end of the external heating shell is connected to a liquid inlet pipe.

[0009] By adopting the above technical solution, unheated antifreeze flows into the first heating chamber through the inlet pipe.

[0010] Specifically, a liquid storage tank is fixedly installed at one end of the outer heating shell, and a connecting pipe is fixedly connected between the liquid storage tank and the inner heating shell, with the interior of the liquid storage tank communicating with the interior of the inner heating shell.

[0011] By adopting the above technical solution, the heated antifreeze will flow into the storage tank through the connecting pipe.

[0012] Specifically, a temperature sensor is installed on one side of the liquid storage tank.

[0013] By adopting the above technical solution, the temperature sensor will detect the antifreeze flowing from the second heating chamber into the storage tank and adjust the direction of the antifreeze according to the temperature of the antifreeze.

[0014] Specifically, one side of the liquid storage tank is fixedly connected to one end of the reflux pipe, the reflux pipe is located inside the outer heating shell, and an electromagnetic valve is sleeved on the outside of the reflux pipe.

[0015] By adopting the above technical solution, when the temperature of the antifreeze is not up to standard, the temperature sensor will open the solenoid valve through the pre-programmed PLC, so that the antifreeze in the storage tank will be discharged from the return pipe into the first heating chamber for reheating.

[0016] Specifically, a circulating liquid pump is fixedly installed on the side of the liquid storage tank away from the connecting pipe, and an outlet pipe is provided on one side of the circulating liquid pump.

[0017] By adopting the above technical solution, when the antifreeze temperature reaches the standard, the temperature sensor will open the circulating fluid pump through the pre-programmed PLC to draw all the antifreeze in the reservoir and discharge it from the outlet pipe to supply the engine.

[0018] The beneficial effects of this utility model are:

[0019] (1) The heating device for automotive antifreeze described in this utility model allows the antifreeze to come into contact with a relatively large heating area in the first heating chamber through the setting of the outer heating shell and the inner heating shell, and allows the antifreeze to flow into the second heating chamber through the connecting hole, thereby increasing the heating time and improving the heating effect of the antifreeze.

[0020] (2) The heating device for automotive antifreeze described in this utility model can detect the temperature of the heated antifreeze by setting a temperature sensor. If the temperature does not meet the standard, it will continue to be discharged into the heating device through the return pipe to continue heating until the temperature meets the standard, and then the circulating liquid pump will extract it to supply the engine.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] In order to increase the heating time and the contact area between the heating device and the antifreeze by setting up a double-layer heating cavity, thereby improving the heating effect, as an embodiment of this utility model, such as Figures 1-3 As shown, the automotive antifreeze heating device of this utility model includes an outer heating shell 10 and an inner heating shell 8. The inner heating shell 8 is fixedly installed inside the outer heating shell 10. One end of the inner heating shell 8 is fixedly connected to the inner end of the outer heating shell 10. A second heating chamber 14 is opened inside the inner heating shell 8, and a first heating chamber 7 is opened inside the outer heating shell 10. A connecting hole 11 is opened at one end of the inner heating shell 8. There are multiple connecting holes 11. The first heating chamber 7 is connected to the second heating chamber 14 through the multiple connecting holes 11.

[0028] The inner heating shell 8 has a second coil mounting cavity 12 inside, which is used for the fixed installation of the second heating coil 13. The outer heating shell 10 is fitted with a heat insulation shell 1 on the outside. A first coil mounting cavity 15 is opened between the heat insulation shell 1 and the outer heating shell 10. The first coil mounting cavity 15 is used for the fixed installation of the first heating coil 9.

[0029] In use, the outer heating shell 10 and the inner heating shell 8 allow the antifreeze to come into contact with a relatively large heating area in the first heating chamber 7, and allow the antifreeze to flow into the second heating chamber 14 through the connecting hole 11, thereby increasing the heating time and improving the heating effect of the antifreeze.

[0030] This utility model also includes a liquid inlet pipe 5 inserted into one end of the outer heating shell 10.

[0031] During use, unheated antifreeze flows into the first heating chamber 7 through the inlet pipe 5.

[0032] The present invention also includes a liquid storage tank 2 fixedly installed at one end of the outer heating shell 10, and a connecting pipe 18 fixedly connected between the liquid storage tank 2 and the inner heating shell 8, wherein the interior of the liquid storage tank 2 is in communication with the interior of the inner heating shell 8.

[0033] When in use, the heated antifreeze will flow from the connecting pipe 18 into the storage tank 2.

[0034] This utility model also includes a temperature sensor 6 installed on one side of the liquid storage tank 2.

[0035] During use, the temperature sensor 6 detects the antifreeze flowing from the second heating chamber 14 into the reservoir 2 and adjusts the flow of the antifreeze according to its temperature.

[0036] The present invention also includes that one side of the liquid storage tank 2 is fixedly connected to one end of the return pipe 16, the return pipe 16 is disposed inside the outer heating shell 10, and an electromagnetic valve 17 is sleeved on the outside of the return pipe 16.

[0037] When the antifreeze temperature is below standard during use, the temperature sensor 6 will open the solenoid valve 17 through the pre-programmed PLC, so that the antifreeze in the reservoir 2 will be discharged from the return pipe 16 into the first heating chamber 7 for reheating.

[0038] The present invention also includes a circulating liquid pump 4 fixedly installed on the side of the liquid storage tank 2 away from the connecting pipe 18, and an outlet pipe 3 is provided on one side of the circulating liquid pump 4.

[0039] When in use, once the antifreeze temperature reaches the target, the temperature sensor 6 will activate the circulating fluid pump 4 via a pre-programmed PLC to draw all the antifreeze from the reservoir 2 and discharge it through the outlet pipe 3 to supply the engine.

[0040] In use, this invention first activates the first heating coil 9 and the second heating coil 13 via an external power supply. Activation of the first heating coil 9 heats the inner wall of the outer heating shell 10, while activation of the second heating coil 13 heats both the inner and outer walls of the inner heating shell 8. Antifreeze enters the first heating chamber 7 through the inlet pipe 5. The antifreeze's contact with the inner wall of the outer heating shell 10 and the outer wall of the inner heating shell 8 provides a large heating area. Subsequently, the antifreeze flows through the connecting hole 11 to the second heating chamber 14, further... The heating time is increased, and finally the coolant flows from the connecting pipe 18 to the reservoir 2. The temperature sensor 6 on one side of the reservoir 2 will measure the temperature of the antifreeze. If the temperature does not meet the standard, the temperature sensor 6 will open the solenoid valve 17 through the pre-programmed program of the PLC, so that the antifreeze in the reservoir 2 will be discharged from the return pipe 16 into the first heating chamber 7 for reheating. After the temperature meets the standard, the temperature sensor 6 will open the circulating liquid pump 4 through the pre-programmed program of the PLC to draw out all the antifreeze in the reservoir 2 and discharge it from the outlet pipe 3 to supply the engine.
