Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-precision test equipment, and in particular to a temperature control assembly for a temperature chamber turntable. BACKGROUND

[0002] The temperature chamber turntable is a multi-scene test equipment integrating high-precision rotation and precise temperature control functions, mainly applied to the fields of inertial navigation, aerospace, material science and automobile manufacturing, etc., and provides a dynamic simulation platform for performance verification of devices under extreme temperature environment. The core function thereof is to realize performance calibration and reliability evaluation of a measured object under thermal-mechanical coupling conditions by synchronously controlling the motion parameters (angular velocity, angular acceleration, position accuracy) of the turntable and the temperature field.

[0003] However, the temperature chamber turntable often induces many problems due to heat conduction. Firstly, the temperature rise of the encoder will cause the accuracy and failure of the turntable. When the heat in the temperature chamber is transmitted to the encoder through the rotor of the turntable, the thermal expansion of the metal code disc will cause the change of the line spacing, which will directly cause the deflection of the grating diffraction angle or the abnormality of the magnetic pole spacing, causing the pulse counting error, and thus causing the measurement error. Secondly, the bearings of the turntable itself are prone to seizure due to thermal expansion of the rotor. Thirdly, the temperature rise of the rotor of the turntable will cause the lubrication failure of the bearings, reducing the service life or accuracy of the turntable.

[0004] Therefore, in order to avoid the above problems caused by heat conduction, the existing temperature chamber turntable will inhibit heat conduction through some technical means. The commonly used schemes mainly include: 1. Thermal insulation design between the workbench and the shaft system, for example, adding a layer of material with high thermal resistance (or low thermal conductivity) as a thermal insulation layer between the workbench and the rotor of the turntable, or increasing the thickness of the thermal insulation layer; 2. Integrating liquid cooling pipeline on the rotor to control the temperature of the rotor by circulating the cooling liquid compressed by an external compressor.

[0005] The above technical schemes have the following disadvantages: 1. Some materials with excellent thermal insulation performance, such as aerogel thermal insulation layer and porous vacuum silicon, have the characteristics of low elastic modulus, and the material itself has poor resistance to deformation, which is prone to cause large displacement or deformation of the workbench surface under load as the support layer of the turntable; 2. If a material with high hardness and good processing performance is used as the thermal insulation layer, the thermal conductivity of this type of material is relatively high, and if a more ideal thermal insulation effect is to be achieved, the thickness of the thermal insulation layer needs to be increased, which will greatly increase the length of the shaft system of the turntable, and the increase of the length of the shaft system will magnify the measurement error caused by the shaft system deflection; 3. Controlling the temperature of the rotor of the turntable by liquid cooling usually has better effect, but integrating the liquid cooling pipeline on the rotor usually needs to use a liquid slip ring, which greatly limits the rotation speed of the turntable (the maximum rotation speed supported by the existing liquid slip ring on the market is about 50 rpm). SUMMARY

[0028] The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] Embodiment one As Figure 1 And Figure 2As shown, the embodiment discloses a temperature control assembly for a temperature box rotary table, which consists of two parts: a stator component connected with the stationary base of the rotary table, and a rotor component rotating with the rotary table, i.e. the stator component is connected with the rotary table stator 10, and the rotor component is connected with the rotary table rotor 11. The rotor component includes a bearing part, a heat insulation part 3 arranged between the bearing part and the rotary table rotor 11, and a rotor end heat dissipation part 4 in thermal conduction connection with the bearing part.

[0030] The bearing part is a platform directly or indirectly bearing the measured part, and is a main area of heat transmission or generation.

[0031] The heat insulation part 3 is an insulating element arranged between the bearing part and the rotor of the rotary table core to form a heat insulation barrier, which blocks the direct conduction of heat along the main shaft direction of the rotary table. In order to meet the dual requirements of structural support and heat insulation, the heat insulation part 3 is preferably made of high-rigidity ceramic material. High rigidity means that the material has strong resistance to deformation, which can ensure the mechanical accuracy of the rotary table; and ceramic material usually has excellent heat insulation performance. The high-rigidity ceramic material can be zirconia ceramic.

[0032] The rotor end heat dissipation part 4 is a heat conduction element connected with the bearing part to collect and guide the heat of the bearing part to a preset heat transmission path. In order to realize efficient heat collection and conduction, the heat dissipation part is preferably made of copper alloy material with excellent heat conductivity.

[0033] The stator component includes a liquid cooling device 6 and a stator end heat dissipation part 5 in thermal conduction connection with the liquid cooling device 6. The liquid cooling device 6 is a high-efficiency heat dissipation equipment that continuously removes heat through internal circulating liquid. The stator end heat dissipation part 5 is made of copper alloy material.

[0034] In work, the surfaces of the rotor end heat dissipation part 4 on the rotor component and the stator end heat dissipation part 5 on the stator component are arranged to face each other, but do not physically contact each other, and a gap avoiding interference is reserved between them, which forms a channel for non-contact heat transmission. Heat can be transmitted from the rotating rotor end heat dissipation part 4 to the stationary stator end heat dissipation part 5 by means of heat radiation and the like, and finally collected to the liquid cooling device 6 for discharge.

[0035] The heat dissipation surfaces of the rotor end heat dissipation part 4 and the stator end heat dissipation part 5 are arranged opposite to each other to form a gap between them for non-contact heat transmission.

[0036] The working principle and operation steps of the embodiment can be summarized as follows: when heat is transmitted from the bearing part, the temperature control assembly manages it through two paths. Path one: the heat insulation piece 3 made of high-rigidity ceramic directly blocks the conduction of heat to the core of the rotary table rotor 11. Path two: the rotor end heat sink 4 made of copper alloy actively conducts heat away from the bearing part, and radiates heat to the stationary stator part through the non-contact gap formed between the rotor end heat sink 4 and the stator end heat sink 5, and finally removes the heat by the liquid cooling device 6.

[0037] Embodiment two The embodiment further elaborates on the mechanical structure and assembly relationship of the rotor part and the stator part based on the foregoing scheme.

[0038] The rotor part further comprises a lower connecting plate 8 connected with the rotary table rotor 11. The bearing part comprises a workbench 1 for mounting the measured part and an upper connecting plate 2, the workbench 1 is fixed to the upper side of the upper connecting plate 2, and the rotor end heat sink 4 is fixed to the lower side of the upper connecting plate 2. The workbench 1 is a top platform for directly mounting the measured part. The workbench 1 is fixed to the upper side of the upper connecting plate 2, and the rotor end heat sink 4 as the starting point of the heat dissipation path is fixed to the lower side of the upper connecting plate 2. This layout enables the heat transmitted from the workbench 1 to be most efficiently transferred to the heat sink directly below it.

[0039] The workbench 1 is used for mounting the measured part and is the working platform of the entire rotary table, bearing the weight of the measured part and the load during work. The upper connecting plate 2 plays a role in supporting and transferring the load. The heat insulation piece 3 is arranged between the upper connecting plate 2 and the lower connecting plate 8. Due to the high rigidity of zirconia ceramic, when the workbench 1 is subjected to a load, the heat insulation piece 3 can withstand a certain pressure, preventing excessive relative deformation of the upper connecting plate 2 and the lower connecting plate 8, and ensuring the stability of the structure.

[0040] The lower connecting plate 8 is connected with the rotary table rotor 11 by screws; the upper connecting plate 2, the heat insulation piece 3 and the lower connecting plate 8 are provided with corresponding through holes, and a long screw passes through the through holes in sequence to fixedly connect the three.

[0041] In order to integrate the three core layers (the upper connecting plate 2, the heat insulation piece 3 and the lower connecting plate 8) into a high-rigidity whole, the embodiment adopts a through-type fastening method. That is, through holes (or screw holes) aligned with each other are arranged on the three layers. During assembly, a long screw is used to pass through the through holes in sequence, thereby firmly fastening the upper connecting plate 2, the heat insulation piece 3 and the lower connecting plate 8 together. While ensuring the structural integration and connection strength, it also ensures that the heat insulation piece 3 can stably play its heat insulation role.

[0042] The stator assembly also includes a fixing plate 7, which is used to secure the liquid cooling device 6 to the turntable stator 10. This fixing plate 7 serves as a connecting bracket, securely securing the liquid cooling device 6 within the stator assembly to the stationary base of the incubator turntable (the turntable stator 10), ensuring assembly stability. To enhance assembly versatility and ease of installation, the fixing plate 7 and the turntable stator 10 are designed to accommodate a variety of standardized connection methods. For example, flange connections secured by bolts or more convenient snap-on connections can be used to accommodate various turntable stator 10 configurations, enhancing assembly ease and versatility.

[0043] This embodiment utilizes a hierarchical structure consisting of a worktable 1 - upper connecting plate 2 - thermal insulation 3 - lower connecting plate 8 , secured with long through-screws. This creates a robust rotor component with a clear thermal path. This ensures that heat is effectively captured by the heat sink under the upper connecting plate 2 while being effectively blocked by the thermal insulation 3 in the middle, preventing it from affecting the lower connecting plate 8 connected to the turntable rotor 11.

[0044] Example 3 Regarding the construction of the non-contact heat transfer interface, this embodiment provides a specific implementation form.

[0045] The rotor-end heat sink 4 includes multiple rotor-end cooling fins, and the stator-end heat sink 5 includes multiple stator-end cooling fins. The multiple rotor-end cooling fins and the multiple stator-end cooling fins are arranged alternately, with gaps provided between adjacent rotor-end cooling fins and stator-end cooling fins to achieve contactless heat transfer. The rotor-end cooling fins and / or the stator-end cooling fins are annular or arc-shaped.

[0046] The two sets of cooling fins aren't simply installed opposite each other, but rather in a staggered arrangement. This "staggered arrangement" can be understood as a structure similar to the teeth of two combs, where the rotor-side fins slot into the gaps between the stator-side fins, and vice versa, while maintaining a non-contact gap between them. This increases the relative surface area between the rotor and stator cooling fins, improving the efficiency of non-contact heat transfer.

[0047] Furthermore, when temperature control components are used in turntables with higher rotational speeds, greater heat dissipation capacity is required to cope with the potential increased heat load. To achieve this, the number and length of the rotor- and stator-end cooling fins can be increased. This increase in number and length directly increases the total heat exchange area, thereby improving overall heat dissipation capacity. Furthermore, the stability of the staggered fin structure must be ensured during this design to prevent vibration-induced collisions or loosening during high-speed rotation.

[0048] For turntables with varying load capacities or thermal insulation requirements, the thickness and dimensions of the thermal insulation element 3 can be customized. For example, for applications with high loads, the thickness of the zirconia ceramic ring can be increased to enhance mechanical support; for applications with extremely high thermal insulation requirements, the thickness can also be increased to improve thermal resistance. This ensures that the overall structural dimensions of the assembly are optimized while maintaining rigidity and thermal insulation, avoiding excessive shaft length.

[0049] Example 4 This embodiment provides another optional structure of a non-contact heat transfer interface. In the above embodiment, the heat sink is implemented as a plurality of interlaced heat dissipation ribs, while this embodiment adopts a more simple structure with relatively arranged planar surfaces.

[0050] In this structure, the rotor-end heat sink 4 and the stator-end heat sink 5 are each implemented as a continuous, flat, annular or disc-shaped planar structure. During assembly, the planes of the rotor-end heat sink 4 and the stator-end heat sink 5 are parallel and facing each other, with a uniform and precise small gap between them.

[0051] The operating principle is that heat is absorbed by the flat surface of the heat-generating rotor-end heat sink 4, primarily through heat radiation, across the tiny gap, and is then absorbed by the flat surface of the stationary stator-end heat sink 5, which is then directed into the liquid cooling device 6. Compared to the complex structure of staggered fins, this structure with opposing planes may be simpler to manufacture and assemble.

[0052] This embodiment achieves non-contact heat transfer by adopting two relatively arranged planar structures, relying on thermal radiation between the planes as the main heat transfer mechanism, and provides a simpler alternative solution for realizing the thermal management function of the present invention under different costs, manufacturing processes or specific performance requirements.

[0053] Example 5 like Figure 3 As shown in FIG, the preferred internal structure of the liquid cooling device 6 as the final heat treatment terminal is described in detail.

[0054] The liquid cooling device 6 is a liquid cooling plate, an annular flow channel for the flow of cooling liquid is provided inside the liquid cooling plate, and a liquid path interface 9 connected to the annular flow channel is provided.

[0055] The liquid circuit interface 9 includes multiple liquid inlets 12 and multiple liquid outlets 13; and the multiple liquid inlets 12 and multiple liquid outlets 13 are distributed along the circumference of the liquid cooling plate; compared with a single inlet and outlet interface, the design of multiple interfaces can support a larger flow rate of coolant circulation, thereby improving the overall heat removal capacity.

[0056] The annular flow channel is serpentine or spiral-shaped, and the core purpose is to maximize the flow path of the cooling liquid within the limited plate area, so that the cooling liquid has longer residence time and larger contact area to absorb the heat of the liquid cooling plate body, thereby improving the efficiency of heat exchange. According to the actual heat dissipation demand, the number, width and depth of these internal flow channels can also be adjusted to adapt to different heat load conditions.

[0057] Example six This embodiment illustrates the complete working process of the temperature control assembly in actual operation, and the detailed working process is as follows: First step: system startup and heat transfer.

[0058] When the temperature control box turntable starts to work, the measured part is installed on the workbench 1. The turntable rotor 11 starts and drives the entire rotor component, including the lower connecting plate 8, the upper connecting plate 2, the workbench 1 and the rotor end heat sink 4 to rotate synchronously. At this time, due to the change of the temperature in the temperature box, heat begins to transfer or is generated by the measured part, and quickly collects on the workbench 1 and the upper connecting plate 2 closely connected thereto.

[0059] Second step: heat path shunting.

[0060] When the heat reaches the upper connecting plate 2, the temperature control assembly guides the heat to two completely different paths for processing.

[0061] Third step: active heat dissipation path.

[0062] Most of the heat is conducted from the upper connecting plate 2 to the rotor end heat sink 4. Then, using the non-contact heat transfer gap formed between the rotor end heat sink 4 and the stationary stator end heat sink 5, the heat is transferred to the stator end heat sink 5. Finally, the heat is guided by the stator end heat sink 5 into the liquid cooling device 6, absorbed by the circulating cooling liquid inside the device, and discharged from the system through the outlet 13, thereby completing the active removal of heat.

[0063] Fourth step: passive heat blocking path.

[0064] At the same time of actively dissipating heat, the heat insulating piece 3 forms a heat insulation barrier by virtue of its low thermal conductivity of the material itself, preventing heat conduction from the upper connecting plate 2 to the lower connecting plate 8 and the deeper turntable rotor 11. In addition, the high rigidity characteristics of the heat insulating piece 3 also ensure that the structure of the rotor component remains stable during the entire working process, even under load, and does not affect the accuracy due to deformation.
