[0026] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0027] The dry-body type temperature calibrator can sense the temperature of the measured object even when the temperature of the measured device or element is being checked, but its response speed may not be fast enough, especially in the case of rapid temperature change, so the rapid heating and cooling function can help the temperature calibrator simulate the rapid temperature change of the measured object in a short time; when the temperature calibrator is in contact with the measured object, thermal equilibrium may be formed or a temperature gradient may be generated, which will affect the accuracy of the temperature sensor reading, and rapid heating and cooling can help shorten the time to establish thermal equilibrium and reduce the influence of temperature gradient, thereby improving the accuracy of measurement; in addition, the temperature calibrator needs to be calibrated and performance evaluated under various temperature conditions, and the rapid heating and cooling function can help the calibrator quickly switch to different temperature ranges and complete calibration and performance evaluation in a short time, improving efficiency and flexibility.

[0028] In view of the temperature difference between the temperature sensor of the comprehensive temperature calibrator and the measured object, the response speed and environmental factors, etc., combined with reference to Figures 1 to 3As shown, the utility model provides a dry body formula temperature check appearance 100, including casing 10, furnace body 20, heat dissipation subassembly 30 and system board subassembly, casing 10 includes base 11 and the upper shell 12 of buckling in base 11, furnace body 20 sets up in casing 10, and is connected to base 11, the furnace mouth of upper shell 12 with furnace body 20 corresponds and is provided with the jack 21 for wearing the element of measuring, heat dissipation subassembly 30 includes heat transfer plate 31 and fin group 32, heat transfer plate 31 covers and sets up in the peripheral wall of furnace body 20, and the multiple heat transfer chambers 311 of intercommunication of the inlayer of heat transfer plate 31 is provided with, fin group 32 is connected with heat transfer plate 31 vertically, system board subassembly is assembled in the front side of upper shell 12.

[0029] As Figure 2 And Figure 3 As shown, in order to facilitate disassembly and installation, casing 10 can be composed of base 11 and upper shell 12, base 11 can be a generally plate-shaped mounting structure for mounting and fixing elements such as furnace body 20, control board assembly, etc. The upper shell 12 can be a box-shaped structure with one end open, and after being buckled and mounted on the base 11, it forms the casing 10 of the temperature check appearance. The connection between the two can be fixedly connected by screws or can be clamped and connected. The furnace body 20, which is a heating element, is one of the key components for providing rapid heating. Generally, it can be a resistor, heating wire, heating plate, etc. It converts electrical energy into heat energy to rapidly increase the temperature of the measured object. The jack 21 can also be provided at the furnace mouth of the furnace body 20 for connecting the measured element. In combination with Figure 3 As shown, in order to rapidly cool the furnace body 20 after heating, a heat transfer plate 31 can be provided around the outer wall of the furnace body 20. The heat transfer plate 31 can have multiple heat transfer chambers 311 stacked inside and interconnected. It should be noted that the heat transfer chamber 311 is a cavity, which can be in the shape of a cuboid, a flat cylinder, or other shapes. The stacked arrangement means that multiple heat transfer chambers 311 are arranged in a direction gradually away from the furnace body 20. By providing the heat transfer chamber 311, the effective surface area of the heat transfer plate 31 can be increased, thereby increasing the area of heat exchange and improving the heat transfer efficiency. It can also promote convective heat transfer. The flow of air or other media in the heat transfer chamber 311 can promote convective heat transfer and speed up the heat transfer rate. The other medium can also be water or coolant. It can also reduce the heat transfer resistance. The heat transfer chamber 311 can reduce the thermal resistance inside the heat transfer plate 31, thereby reducing the heat transfer resistance and improving the heat transfer efficiency.

[0030] In combination with Figure 2As shown, the fin group 32 can be composed of a plurality of fins 32, which can be sheet-shaped aluminum foils, and the fins can be arranged in parallel and spaced apart from each other. The fin group 32 can be connected to the heat transfer plate 31 integrally by welding, crimping or bonding. The heat generated by the furnace body 20 can be transmitted to the fin group 32 by the heat transfer plate 31. The fin group 32 has a larger heat dissipation area and can more efficiently dissipate heat. It should be noted that the fin group 32 can be provided in two groups, and the two groups of fin groups 32 are oppositely arranged to make the heat dissipation more efficient. A plurality of groups can also be provided, and the specific arrangement can also be made according to the specific shape of the heat transfer plate 31 after being arranged on the furnace body 20. For example, the heat transfer plate 31 forms a cylindrical shape after enclosing the furnace body 20, and the fin group 32 can be arranged on the outer wall of the heat transfer plate 31 in the circumferential direction. The heat transfer plate 31 forms a four-sided body after enclosing the furnace body 20, and the fin group 32 can be arranged on the four side walls or the opposite two side walls formed by the heat transfer plate 31.

[0031] The system board assembly 40 is equivalent to the brain of the dry body type temperature calibrator 100, and includes a display panel (not shown), a control board assembly (not shown), a measurement board assembly (not shown), etc. The display panel and the control board assembly interact with each other in data, that is, the control board assembly reads the temperature data measured by the sensor group, the electrical signal data measured by the measurement board assembly, and various parameters set by the system board assembly 40, and then generates a control command according to a predetermined control strategy and execution sequence and sends the control command to the execution mechanism of the heat dissipation assembly 30, and sends the processed data to the display panel for display.

[0032] For reference Figure 3 As shown, in an embodiment of the present application, a through hole 312 is formed on the cavity wall of each heat transfer chamber 311 to communicate with another heat transfer chamber 311 adjacent thereto.

[0033] The through hole 312 formed on the cavity wall of the heat transfer chamber 311 can make the heat transfer chambers 311 communicate with each other, so that heat can be more uniformly transmitted to the surface of the entire plate, avoiding the situation of local heat accumulation or uneven heat transfer.

[0034] For reference Figure 3 As shown, in an embodiment of the present application, an exhaust hole 313 is further arranged on the cavity wall of the heat transfer chamber 311 adjacent to the fin group 32, and the exhaust hole 313 communicates with the outside.

[0035] During the heat transfer process of the heat generated by the furnace body 20 in the heat transfer chamber 311, the air heated and expanded can cause the heat transfer chamber 311 to deform or rupture. The exhaust hole 313 can reduce the tensile stress generated by the air heated and expanded in the heat transfer chamber 311, so that the heat can be discharged to the outside, and the heat transfer chamber 311 will not be heated and expanded due to the circulation of heat inside the heat transfer chamber 311.

[0036] In an embodiment of the present application, a heat-conducting base (not shown) is arranged at the connection between the heat transfer plate 31 and the fin group 32.

[0037] In order to further enhance the heat transfer efficiency between the heat transfer plate 31 and the fin group 32, a heat-conducting base can be arranged at the connection between the heat transfer plate 31 and the fin group 32. The heat-conducting base can be made of a material with good heat-conducting properties, such as aluminum alloy, copper, or other metal materials, or can be a ceramic substrate, to ensure that heat can be quickly conducted to the fin group 32 or the surrounding environment.

[0038] With reference to Figure 2 As shown in the drawings, in an embodiment of the present application, a plurality of refrigeration fins 314 are further embedded in the heat transfer plate 31, the cold end of the refrigeration fin 314 is arranged close to the furnace body 20, and the hot end of the refrigeration fin 314 is arranged close to the fin group 32.

[0039] As can be understood, the refrigeration fin 314 can transfer the heat generated on one side of the furnace body 20 to the side of the fin group 32, thereby reducing the temperature on one side of the furnace body 20. The refrigeration fin 314 can be made of a heat-conducting material (aluminum, copper, or other metals) to effectively conduct and dissipate heat. The temperature of the furnace body 20 can be effectively controlled by the refrigeration fin 314 to ensure normal operation and improve its performance and reliability.

[0040] With reference to Figure 2 As shown in the drawings, in an embodiment of the present application, a plurality of sensing elements 315 are further arranged on the heat transfer plate 31, and the probe portion of the sensing element 315 is embedded in the bottom or sidewall of the heat transfer plate 31.

[0041] The sensing element 315 can include a differential thermocouple, a thermal resistance temperature sensor, and an over-temperature alarm sensor. The sensing element 315 can be installed in a plurality of mounting vias of the heat transfer plate 31, and the probe portion thereof can be close to or abut against the bottom or sidewall of the furnace body 20. The sensing element 315 transmits the measured temperature data to the system board assembly 40, which processes the data for temperature increase or decrease and displays the data on the display panel. The temperature information of the furnace body 20 can be obtained in real time through the sensing element 315, which facilitates automatic or manual timely regulation and control.

[0042] With reference to Figure 2 As shown in the drawings, in an embodiment of the present application, the heat dissipation assembly 30 further comprises a refrigeration fan 33, which is installed on the base 11 and has an air outlet surface facing the furnace body 20.

[0043] The air outlet direction of the refrigeration fan 33 is along the extension direction of the internal gap of the fin group 32, and the refrigeration fan 33 can accelerate the heat dissipation of the fin group 32. The refrigeration fan 33 is electrically connected to the system board assembly 40, and the start-stop and rotation speed of the refrigeration fan 33 can be controlled by the system board assembly 40 to control the temperature of the furnace body 20.

[0044] In combination with reference to Figure 1 and Figure 2 As shown in the drawings, in an embodiment of the present application, the upper shell 12 is provided with a plurality of heat dissipation holes 121 on the side opposite to the refrigeration fan 33.

[0045] Further, in order to quickly dissipate heat to the outside, a plurality of heat dissipation holes 121 can be provided on the side opposite to the refrigeration fan 33 to increase the air flow rate and further accelerate the heat dissipation.
