Description

Technical Field

[0001] This invention relates to the field of calibration furnace heaters, and more particularly to a metrological calibration furnace heater for engines. Background Technology

[0002] During engine manufacturing and testing, various tests and calibrations are required. One crucial test is the engine power test, which evaluates its output power and thermal efficiency under different operating conditions. To ensure the accuracy and repeatability of the test, a metrology calibration furnace heater is used to control the heat input to the engine. A traditional metrology calibration furnace heater typically consists of a heating furnace and a heat exchanger. The heating furnace regulates its temperature by controlling the heater's power and temperature, thereby simulating environmental conditions under different operating conditions. The heat exchanger transfers the heat generated by the heater to the engine under test, while simultaneously controlling the amount of heat transferred to ensure that the engine receives a stable and accurate heat input under various operating conditions.

[0003] The inventors discovered the following problems during practical use:

[0004] The heat exchanger in the heating furnace requires a large amount of cooling water to control the temperature of the engine under test, which increases the testing cost and complexity. Furthermore, traditional metrology calibration furnace heaters lack automated detection and control functions, requiring manual intervention to adjust test parameters and record data, increasing testing time and difficulty.

[0005] Therefore, it is necessary to provide a metering calibration furnace heater for engines to solve the above-mentioned technical problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a metering and calibration furnace heater for engines, in view of the above-mentioned defects of the prior art.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: a metering and calibration furnace heater for an engine, comprising a furnace body, a square opening on one side of the furnace body, an automatic controller fixedly attached to the inner side of the square opening, one side of the automatic controller located outside the furnace body, and the other side of the automatic controller located inside the furnace body, a switch and an electronic screen on one side of the automatic controller, multiple regulators arranged equidistantly below the electronic screen, round openings at both the top and bottom of one side of the furnace body, a conductive port fixedly installed inside the round opening, a heating tube fixedly connected to one end of the conductive port, multiple temperature sensors equidistantly distributed on the outer side of the heating tube, a heat exchanger fixedly installed on the bottom inside the furnace body, one end of the heat exchanger fixedly connected to one end of the heating tube, a cooling tube on the outer side of the heat exchanger, a circulating cooler fixedly installed on the top outside the furnace body, the interior of the circulating cooler fixedly connected to one end of the cooling tube, and symmetrical start buttons on the top of the circulating cooler. By controlling the start buttons, the interior of the cooling tube can be filled with coolant to absorb excess heat, maintain a uniform temperature, and improve heat exchange efficiency.

[0008] By adopting the above technical solution, when the conductive port is powered on from the outside of the furnace body, the heating tube will start heating. The temperature sensor on the outside of the heating tube will detect its operating temperature and transmit the data to the automatic controller, thus achieving automatic control.

[0009] Optionally, the temperature sensor controller includes a temperature control ring, and an insulating wire is fixedly connected to one side of the temperature control ring. One end of the insulating wire is fixedly connected to one side of the automatic controller.

[0010] By adopting the above technical solution, the temperature control loop is used to detect and automatically control the temperature of the heating element. The data can be transmitted to the automatic controller through the insulated wire, so that human observation and intervention can be carried out in special circumstances.

[0011] Optionally, one side of one of the conductive ports is fixedly connected to one end of the heating tube, and one side of the other conductive port is fixedly connected to the other end of the heating tube.

[0012] By adopting the above technical solution, the heating efficiency of the heating tube is increased and the temperature rise is accelerated.

[0013] Optionally, the heat exchanger includes heat exchange plates, with input pipes fixedly connected to both the upper and lower ends of one side of the heat exchange plate, and output pipes fixedly connected to both the bottom ends of the other side of the heat exchange plate. One end of the output pipe passes through the furnace body and is located outside the furnace body.

[0014] By adopting the above technical solution, heat is conducted to the interior of the heat exchanger through the input pipe for adjustment and control, and the adjusted heat is transferred to the engine outside the furnace body through the output pipe.

[0015] Optionally, the heating tube has holes at both the upper and lower bends, and the inner side of the holes is fixedly connected to the outer side of one end of the input tube.

[0016] By adopting the above technical solution, the heat generated after the heating tube is heated can be directly conducted through the tube hole to the input tube and reach the interior of the heat exchange plate, thereby reducing the heat loss during the heat transfer process and reducing the thermal efficiency of the heat exchange plate.

[0017] Optionally, the cooling pipe includes a condensation inlet, a condensation outlet, a U-shaped pipe, and an annular pipe. The condensation inlet passes through the inside of one of the circular holes and is fixedly connected to the inside of the circulating cooler. The condensation outlet passes through the inside of the other circular hole and is fixedly connected to the inside of the circulating cooler.

[0018] By adopting the above technical solution, the coolant inside the circulating cooler can be output to all positions inside the cooling pipe through the condenser inlet, and the coolant inside the cooling pipe can be input back into the circulating cooler through the condenser outlet.

[0019] Optionally, the U-shaped tube is located at the top inner side of the furnace body, and the annular tube is arranged around the outside of the heat exchange plate.

[0020] By adopting the above technical solution, the coolant inside the cooling pipe takes longer to flow to the position of the U-shaped pipe and the annular pipe, thereby continuously reducing the ambient temperature.

[0021] Optionally, the inner side of the temperature control ring is fixedly sleeved with the outer side of the heating tube, and the installation positions of the temperature control ring are respectively located at both ends of the heating tube and on the outer side of the bend.

[0022] By adopting the above technical solution, the temperature control loop can detect multiple positions of the heating element, thereby reducing detection and control errors caused by temperature differences at different positions.

[0023] Optionally, the sensors set at multiple points within the temperature control loop are connected to the automatic controller for signal transmission.

[0024] By adopting the above technical solution, the automatic controller can continuously receive dynamic temperature information from the sensors inside the temperature control loop, thereby achieving temperature measurement and calibration.

[0025] Optionally, the automatic controller is connected to the engine's sensors and actuators via the engine control module.

[0026] By adopting the above technical solution, the automatic controller can be synchronized with the test status data of the engine under test, and can perform corresponding corrections and temperature calibrations in real time.

[0027] Compared with related technologies, the metering calibration furnace heater for engines provided by the present invention has the following beneficial effects:

[0028] This invention provides a heater for a calibration furnace for engines. An automatic controller is located outside the furnace body, and an insulating wire and a temperature control ring are connected to the controller on one side inside the furnace body. The temperature control rings are distributed at multiple locations on the heating tubes to prevent temperature and power errors caused by different heating tube positions. This allows for precise detection and control of the heating tube's power and heating temperature, achieving automatic control. Simultaneously, data is transmitted to the automatic controller via the insulating wire, and power and temperature can be observed on an electronic screen. In special circumstances, the heating tube's working effect can be controlled manually by adjusting the regulator. This solves the technical problem of the lack of automated detection and control in calibration furnace heaters and also reduces the difficulty of testing.

[0029] This invention provides a metering and calibration furnace heater for engines. It employs a cooling pipe inside the furnace body, connected to a circulating cooler via a condenser inlet. The condenser inlet allows coolant to be pumped into the cooling pipe, and the condenser outlet connects to the circulating cooler, allowing the coolant inside the cooling pipe to return to the circulating cooler. This reduces waste compared to traditional cooling water, and the circulating coolant allows for reuse, lowering costs. The U-shaped pipe design extends the coolant's flow time within the furnace body, absorbing excess heat. The annular pipe design, surrounding the heat exchangers, ensures the coolant effectively absorbs heat from the heat exchangers as it passes through, reducing the surrounding temperature and improving heat exchanger efficiency. This allows for rapid heat processing and conversion, reducing costs and complexity. Attached Figure Description

Detailed Implementation

[0039] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings. Typical embodiments of the present invention are shown in the drawings.

[0040] like Figures 1-2 As shown, a metering calibration furnace heater for an engine according to the present invention includes a furnace body 1. An automatic controller 2 is installed on the outside of the furnace body 1, with one side of the automatic controller 2 located inside the furnace body 1. A conductive port 5 is fixedly installed on one side of the furnace body 1, and a heating tube 3 is fixedly connected to one end of the conductive port 5. Heating power is provided to the heating tube 3 through the conductive port 5. Multiple temperature sensors 4 are installed on the outside of the heating tube 3. At this time, the temperature status of the heating tube 3 can be detected by the temperature sensors 4 on the outside of the heating tube 3, and the data is transmitted to the automatic controller 2, achieving the effect of automatic control. In addition, a heat exchanger 6 is fixedly installed on the bottom side inside the furnace body 1, and one end of the heat exchanger 6 is fixedly connected to one end of the heating tube 3. The heat generated by the heating tube 3 can be directly transferred to the heat exchanger 6 for regulation and control. In addition, a cooling tube 7 is arranged around the outside of the heat exchanger 6, and a part of the cooling tube 7 is arranged on the inner top of the furnace body 1. A circulating cooler 8 is installed on the top of the furnace body 1 and connected to the cooling tube 7. In application, the cooling tube 7 can be filled with coolant by activating the start button 801 to fully absorb excess heat, keep the temperature balanced, and improve working efficiency.

[0041] like Figure 3As shown, the square opening 101 on one side of the furnace body 1 is used to fix the automatic controller 2, the round opening 102 allows the conductive port 5 to pass through and be fixed, and the round hole 103 allows one end of the cooling pipe 7 to pass through and be fixed.

[0042] like Figures 4-5 As shown, when the heating tube 3 is heating, the temperature control rings 401 distributed at both ends and the bends of the heating tube 3 can detect the real-time temperature and filtration status of each part of the heating tube 3, and transmit the data to the automatic controller 2 through the insulating wire 402 and display it on the electronic screen 202. At this time, the automatic controller 2 can control the temperature and power of the heating tube 3 through the temperature control rings 401 after automatic processing. The working state of the heating tube 3 can be quickly turned off and on by setting the switch 201.

[0043] In practice, an external power supply is connected through one end of the conductive port 5, and the working state of the heating tube 3 is quickly turned off and on by the switch 201. Since the temperature control ring 401 is distributed in multiple positions of the heating tube 3, it can detect the real-time temperature and filtration of each part of the heating tube 3, reducing the possible temperature, power and error, thereby achieving the effect of automatic control of the heating tube 3. At the same time as control and detection, the data can be transmitted to the automatic controller 2 through the insulated wire 402. The power, temperature and other conditions can be observed through the electronic screen 202. In special cases, the working effect of the heating tube 3 can be controlled by manually operating the regulator 203, thereby solving the technical problem of lack of automated detection and control of the calibration furnace heater, and also reducing the difficulty of testing.

[0044] like Figures 6-7 As shown in the figure, based on Embodiment 1, the present invention provides a technical solution: when the heating tube 3 is working and heating, the heat generated can be quickly transferred to the inside of the input tube 602 through the tube hole 301 to avoid heat loss. At this time, the heat can be transported to the inside of the heat exchange plate 601 through the input tube 602 for regulation and control. During operation, the outside of the heat exchange plate 601 is surrounded by the cooling tube 7, so that the coolant inside the cooling tube 7 will carry away some of the excess heat of the heat exchange plate 601, so that the heat exchange plate 601 will always maintain a suitable temperature. Finally, the regulated heat is transported to the inside of the engine through the output tube 603, thereby completing the engine test.

[0045] like Figure 8As shown, coolant can be poured into the interior of cooling pipe 7 through the condenser inlet 701, and the coolant inside cooling pipe 7 can be returned to the interior of circulating cooler 8 through condenser outlet 702 for reuse, thereby reducing costs. Then, the design of U-shaped tube 703 increases the flow time of coolant inside furnace body 1, which can absorb excess heat inside furnace body 1. Finally, the design of annular tube 704, which surrounds the outside of heat exchange plate 601, allows coolant to fully absorb heat when passing through annular tube 704, thereby reducing the surrounding temperature and improving working efficiency.

[0046] During implementation, when the heating tube 3 is working, the heat generated by the heating tube 3 can be quickly transferred to the inside of the input tube 602 through the tube hole 301 to prevent heat loss. At this time, the heat can be transported to the inside of the heat exchange plate 601 through the input tube 602 for regulation and control. At the same time, by pressing the start button 801, the coolant inside the circulating cooler 8 enters from the condenser inlet 701, which can pour the coolant into the inside of the cooling tube 7. The coolant inside the cooling tube 7 returns to the inside of the circulating cooler 8 through the condenser outlet 702, thus reusing it and reducing costs. Then, the design of the U-shaped tube 703 increases the flow time of the coolant inside the furnace body 1, which can absorb excess heat inside the furnace body 1. Finally, the design of the annular tube 704, which flows around the outside of the heat exchange plate 601, allows the coolant to fully absorb heat when passing through the annular tube 704, reducing the surrounding temperature and improving working efficiency. Finally, the heat regulated by the temperature control of the heat exchange plate 601 is transported to the inside of the engine through the output tube 603, thus completing the engine test.

[0047] In practical applications, this invention provides a metrology calibration furnace heater for engines. The sensors and actuators of the engine under test are connected to the furnace heater via the engine control module. It can simulate different operating conditions to test the performance and accuracy of the engine control module. The heater uses electric heating to raise the temperature and adjust parameters such as fuel, water, and oil temperature to the required values, simulating different operating states. By changing the heater's heating power and the accuracy of the temperature control system, different operating conditions can be simulated to test the engine control module's response time and control accuracy. Furthermore, by changing the control parameters, higher testing accuracy can be achieved. This solves the technical problem of the calibration furnace heater lacking automated detection and control, while also reducing the difficulty of testing. It also allows the coolant to fully absorb heat from the heat exchanger locations, lowering the temperature around the heat exchangers during operation, improving the heat exchanger's efficiency, and enabling rapid processing and conversion of internal heat for output, thus reducing cost and complexity.

[0048] In practical applications, the metering calibration furnace heater for engines of the present invention can also be equipped with a data storage device to record test data, facilitating subsequent data analysis and optimization.

[0049] The implementation principle of a calibration furnace heater for an engine according to an embodiment of this application is as follows: First, an external power supply is connected through one end of the conductive port 5, and the working state of the heating tube 3 is quickly turned off and on by the switch 201. Since the temperature control ring 401 is distributed at multiple positions of the heating tube 3, it can detect the real-time temperature and filtration of each part of the heating tube 3, reducing the possible temperature, power and error, thereby achieving the effect of automatic control of the heating tube 3. While controlling and detecting, the data can be transmitted to the automatic controller 2 through the insulated wire 402. The power, temperature and other conditions can be observed through the electronic screen 202. In special cases, the working effect of the heating tube 3 can be controlled by manually operating the regulator 203, thereby solving the technical problem of lack of automated detection and control of the calibration furnace heater, and also reducing the difficulty of testing. After the heating tube 3 is working and heating, the heat generated can be quickly transferred to the input pipe through the tube hole 301. To prevent heat loss, heat is transferred to the heat exchanger 601 via the input pipe 602 for regulation and control. Simultaneously, by activating the start button 801, coolant from the circulating cooler 8 is pumped from the condenser inlet 701 into the cooling pipe 7. The coolant then returns to the circulating cooler 8 via the condenser outlet 702 for reuse, reducing costs. The U-shaped tube 703 design extends the coolant's flow time within the furnace body 1, absorbing excess heat. Finally, the annular tube 704, surrounding the heat exchanger 601, allows the coolant to fully absorb heat as it passes through, lowering the surrounding temperature and improving efficiency. The heat regulated by the heat exchanger 601 is then transferred to the engine via the output pipe 603, completing the engine test.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
