Description
一种温度计感温头 技术领域 Thermometer temperature sensor
本发明涉及一种温度计测温装置， 更具体地说， 涉及一种温度计感温头。 景 The present invention relates to a thermometer temperature measuring device, and more particularly to a thermometer temperature sensing head. Scene
感温头是温度计的重要部件。温度计通过感温头获取被测物温度，而后对 被测物温度进行计量显示，达到测量被测物温度的目的。感温头的敏感性一一 即感温头感知被测物温度的快慢，是评价温度计测量性能的重要指标，决定着 温度计测取温度的快慢。敏感性好的感温头可以迅速获取被测物温度，大大缩 短使用者测取温度的时间，因此，提高感温头敏感性成为人们改进温度计性能 的重要课题。 The temperature sensing head is an important part of the thermometer. The thermometer obtains the temperature of the measured object through the temperature sensing head, and then measures the temperature of the measured object to achieve the purpose of measuring the temperature of the measured object. The sensitivity of the temperature sensor is the speed at which the temperature sensor senses the temperature of the measured object. It is an important indicator for evaluating the measurement performance of the thermometer and determines the temperature of the thermometer. The sensitive temperature sensor can quickly obtain the temperature of the measured object and greatly shorten the time for the user to measure the temperature. Therefore, improving the sensitivity of the temperature sensor becomes an important issue for improving the performance of the thermometer.
如图 1所示，安装在温度计塑料壳体头部 1的传统的感温头是在金属壳体 2的内壁上设置温度传感器 5， 并用导热材料 4 (如 AB胶）填充金属壳体 2 的内腔，将温度传感器 5固定在金属壳体 2的内壁上并将金属壳体 2的热量传 递到温度传感器 5上，温度传感器 5通过导线 3将温度信息传递给温度计计量 显示电路进行温度显示。 As shown in FIG. 1, the conventional temperature sensing head mounted on the thermometer plastic housing head 1 is provided with a temperature sensor 5 on the inner wall of the metal casing 2, and the metal casing 2 is filled with a heat conductive material 4 (such as AB glue). The inner cavity fixes the temperature sensor 5 to the inner wall of the metal casing 2 and transfers the heat of the metal casing 2 to the temperature sensor 5. The temperature sensor 5 transmits the temperature information to the thermometer metering display circuit through the wire 3 for temperature display.
在进一步提高感温头敏感性的研究中，人们发现，作为填充物的导热材料 4存在一定的热容， 传递热量时会产生一定的热传递滞后， 降低了传统感温头 的敏感性； 同时传统感温头的温度传感器与金属壳体为点接触， 接触面积小， 热传递速度慢， 因而出现了如图 2所示的改进型感温头。该感温头采用弹性绝 热材料 6 (如聚苯乙烯泡沫 (EPS)等）替代导热材料 4作为填充材料对金属壳 体 2进行填充固定温度传感器 5， 同时在温度传感器与金属壳体之间增加具有 导热能力的传热胶 7 (如 AB胶)， 传热胶一方面将温度传感器 5粘结固定在 金属壳体 2的内壁上，另一方面使温度传感器 5与金属壳体 2的点接触变为面 接触， 提高了金属壳体 2与温度传感器 5之间的传热速度， 同时绝热材料 6 保持传递到温度传感器 5上的热量不散失， 从而使感温头的敏感性得到提高， 使得现有温度计可在 30秒内完成温度测量。 In the study of further improving the sensitivity of the temperature sensitive head, it has been found that the thermal conductive material 4 as a filler has a certain heat capacity, and a certain heat transfer hysteresis is generated when heat is transferred, which reduces the sensitivity of the conventional temperature sensing head; The temperature sensor of the conventional temperature sensor is in point contact with the metal casing, the contact area is small, and the heat transfer speed is slow, so that the improved temperature sensing head as shown in FIG. 2 appears. The temperature sensing head uses an elastic heat insulating material 6 (such as polystyrene foam (EPS), etc.) instead of the heat conductive material 4 as a filling material to fill the metal housing 2 with the fixed temperature sensor 5, and increases between the temperature sensor and the metal housing. Heat transfer adhesive 7 (such as AB glue) having heat conductivity, the heat transfer adhesive adheres and fixes the temperature sensor 5 on the inner wall of the metal casing 2 on the one hand, and contacts the point contact of the temperature sensor 5 and the metal casing 2 on the other hand. Turning into a surface contact increases the heat transfer speed between the metal casing 2 and the temperature sensor 5, and the heat insulating material 6 keeps the heat transferred to the temperature sensor 5 from being lost, thereby improving the sensitivity of the temperature sensing head, thereby making it possible to improve the sensitivity of the temperature sensing head. Existing thermometers can complete temperature measurements in 30 seconds.
