Description

Technical Field

[0001] This utility model relates to the field of electric heater technology, and in particular to a high-pressure lubricating oil cast aluminum heater. Background Technology

[0002] In aircraft component testing systems, the use of high-pressure lubricating oil is crucial, and its temperature is subject to strict requirements. However, due to the high operating pressure of this lubricating oil (up to 35 MPa), existing heating technologies and equipment face numerous challenges.

[0003] When using conventional large containers to manufacture heaters, the containers are often enormous and require a large floor space due to the need to withstand such high pressures. This not only hinders compact equipment design but also increases manufacturing complexity. Furthermore, to meet high-pressure requirements, the steel plates for the equipment cylinder must reach a certain thickness, which undoubtedly increases material costs and processing complexity, further driving up overall costs. In addition, the heavy steel plates also increase the difficulty of equipment inspection and maintenance, raising operating costs.

[0004] On the other hand, while directly heating the lubricating oil with a heater seems simple and straightforward, the surface temperature of the heating element can easily become too high, leading to oil deterioration and affecting lubrication performance and the normal operation of the equipment. In extreme cases, excessively high temperatures can even cause pipe ruptures and other safety accidents, posing a serious threat to personnel and equipment.

[0005] Conventional oil-to-oil heat exchangers also have shortcomings. Their thermal efficiency is generally low, making it difficult to meet the high-efficiency requirements of heating high-pressure lubricating oil. Furthermore, their large size poses certain safety hazards during use, such as leaks and explosions, further increasing the risks involved.

[0006] In summary, existing technologies and equipment for heating high-pressure lubricating oil suffer from problems such as large size, high cost, low thermal efficiency, and safety hazards. Utility Model Content

[0007] The purpose of this utility model is to provide a high-pressure lubricating oil cast aluminum heater, which aims to solve the technical problems of existing technologies and equipment for heating high-pressure lubricating oil, such as large size, high cost, low thermal efficiency, and safety hazards.

[0008] To achieve the above objectives, this utility model employs a high-pressure lubricating oil cast aluminum heater, comprising a mounting frame, an aluminum ingot, a heating tube, a coil, and a junction box. The aluminum ingot is disposed within the mounting frame, and both the heating tube and the coil are disposed within the interlayer of the aluminum ingot. The heating tube is tightly fitted to and sandwiched within the coil, and is circumferentially distributed along the axial centerline of the aluminum ingot. The junction box is disposed on the mounting frame and connected to the heating tube. The coil has an inlet and an outlet, both of which penetrate the mounting frame.

[0009] The high-pressure lubricating oil cast aluminum heater also includes a cover plate, which is disposed on the mounting frame and located above the mounting frame.

[0010] Molten aluminum is filled between the heating tube and the coil.

[0011] The high-pressure lubricating oil cast aluminum heater further includes a support member, a force-applying unit, two force-bearing plates, two sliding plates, a spring, two inserts, and a connector. The support member is fixedly connected to the mounting frame and has a groove, two through holes, and a mounting slot. The connector is connected to the junction box and is placed in the mounting slot. The connector has two slots. Both sliding plates are slidably connected to the groove. The two force-bearing plates are fixedly connected to their respective sliding plates. The two inserts are fixedly connected to their respective sliding plates and are placed in their respective slots. The two ends of the spring are fixedly connected to the two sliding plates. The force-applying unit is used to drive the two force-bearing plates to move.

[0012] The force-applying unit includes a rotating rod and an elliptical plate. The rotating rod is rotatably connected to the support member, and the elliptical plate is fixedly connected to the rotating rod. Both elliptical plates are in contact with the two force-bearing plates.

[0013] This invention relates to a high-pressure lubricating oil cast aluminum heater. The aluminum ingot is used to hold the high-pressure lubricating oil. The invention involves casting the heating tube and a coil wound to a specified size together into the aluminum ingot. The molten aluminum fills the space between the coil and the heating tube, increasing the heat exchange efficiency between them, significantly reducing energy loss and improving heating efficiency. The coiled shape increases the heat exchange area and extends the heat exchange time, achieving better heat exchange results. By using an installation method where the heating tube is tightly wrapped around the coil in a circumferential arrangement, the heat exchange distance is shortened, improving the temperature uniformity of the entire aluminum ingot heater. This method solves the technical problems of existing technologies and equipment for heating high-pressure lubricating oil, such as large size, high cost, low thermal efficiency, and safety hazards.

[0014] Meanwhile, this utility model has a small size and compact structure. It occupies a small area and has a high space utilization rate. This utility model has high safety performance and does not have the problem of oil deterioration due to overheating. This utility model has a wide range of applications and is not limited to one product. It can be extended to the heating of other similar materials. Attached Figure Description

[0027] This utility model provides a high-pressure lubricating oil cast aluminum heater, including a mounting frame 101, an aluminum ingot 102, a heating tube 103, a coil 104, and a junction box 105. The aluminum ingot 102 is disposed within the mounting frame 101. The heating tube 103 and the coil 104 are both disposed within the interlayer of the aluminum ingot 102. The heating tube 103 tightly wraps around the coil 104 and is circumferentially distributed along the axial center line of the aluminum ingot 102. The junction box 105 is disposed on the mounting frame 101 and connected to the heating tube 103. The coil 104 has an inlet 106 and an outlet 107, both of which penetrate the mounting frame 101.

[0028] Molten aluminum is filled between the heating tube 103 and the coil 104.

[0029] In this specific embodiment, the aluminum ingot 102 is used to hold high-pressure lubricating oil. This invention, by casting the heating tube 103 and the coil 104 wound to a specified size together into the aluminum ingot 102, increases the heat exchange efficiency between the two by filling the space between the coil 104 and the heating tube 103 with molten aluminum, significantly reducing energy loss and improving heating efficiency. The coil 104, by being coiled, increases the heat exchange area and extends the heat exchange time, achieving a better heat exchange effect. By using an installation method where the heating tube 103 is tightly wrapped around the coil 104 in a circumferential arrangement, the heat exchange distance is shortened, and the temperature uniformity of the entire aluminum ingot heater is improved. This method solves the technical problems of existing technologies and equipment for heating high-pressure lubricating oil, such as large size, high cost, low thermal efficiency, and safety hazards.

[0030] Meanwhile, this utility model has a small size and compact structure. It occupies a small area and has a high space utilization rate. This utility model has high safety performance and does not have the problem of oil deterioration due to overheating. This utility model has a wide range of applications and is not limited to one product. It can be extended to the heating of other similar materials.

[0031] Furthermore, the high-pressure lubricating oil cast aluminum heater also includes a cover plate 108, which is disposed on the mounting frame 101 and located above the mounting frame 101.

[0032] In this specific embodiment, the cover plate 108 is used to prevent foreign objects from entering the high-pressure lubricating oil.

[0033] Secondly, the high-pressure lubricating oil cast aluminum heater also includes a support member 109, a force-applying unit, two force-bearing plates 110, two sliding plates 111, a spring 112, two inserts 113, and a connector 114. The support member 109 is fixedly connected to the mounting frame 101. The support member 109 has a groove 115 and two through holes 116, and a mounting groove 120. The connector 114 is connected to the junction box 105, and the connector 114 is placed within the... Within the mounting slot 120, the connector 114 has two slots 117, both slide plates 111 are slidably connected to the groove 115, the two force plates 110 are fixedly connected to their respective slide plates 111, the two inserts 113 are fixedly connected to their respective slide plates 111, and the two inserts 113 are respectively placed in their respective slots 117, the two ends of the spring 112 are fixedly connected to the two slide plates 111, and the force application unit is used to drive the two force plates 110 to move.

[0034] In this specific embodiment, when the junction box 105 needs to be installed, the force application unit first drives the two force plates 110 to move relative to each other, and drives the two sliding plates 111 to move relative to each other, thereby causing the spring 112 to extend. The sliding plates 111 drive the insert 113 to move. Then, the connector 114 is placed in the mounting groove 120 and pushed to the designated position. The force application unit is then released. At this time, the spring 112 returns to its original position and drives the two sliding plates 111 to move towards each other, thereby driving the two inserts 113 to be inserted into the corresponding slots 117 to complete the installation. Conversely, this facilitates disassembly.

[0035] Furthermore, the force-applying unit includes a rotating rod 118 and an elliptical plate 119. The rotating rod 118 is rotatably connected to the support member 109, and the elliptical plate 119 is fixedly connected to the rotating rod 118. The elliptical plate 119 is in contact with both force-bearing plates 110.

[0036] In this specific embodiment, the round rod is held and force is applied, causing the round rod to rotate the elliptical plate 119, which in turn causes the force-bearing plate 110 to move.

[0037] This invention discloses a high-pressure lubricating oil cast aluminum heater. The aluminum ingot 102 is used to hold the high-pressure lubricating oil. The invention involves casting the heating tube 103 and the coil 104 wound to a specified size together into the aluminum ingot 102. The molten aluminum fills the space between the coil 104 and the heating tube 103, increasing the heat exchange efficiency between them, significantly reducing energy loss and improving heating efficiency. The coil 104 is coiled to increase the heat exchange area and extend the heat exchange time, achieving better heat exchange results. The installation method, in which the heating tube 103 is tightly wrapped around the coil 104 in a circumferential arrangement, shortens the heat exchange distance and improves the temperature uniformity of the entire aluminum ingot heater. This method solves the technical problems of existing technologies and equipment for heating high-pressure lubricating oil, such as large size, high cost, low thermal efficiency, and safety hazards.

[0038] Meanwhile, this utility model has a small size and compact structure. It occupies a small area and has a high space utilization rate.
