Description

Technical Field

[0001] This utility model relates to the field of temperature monitoring equipment technology, specifically to a high-temperature early warning external protection device. Background Technology

[0002] In the operation of modern thermal power plants, many pieces of equipment operate continuously in high-temperature environments for extended periods, such as temperature sensors that detect whether the ambient temperature is normal. However, in actual use, it has been found that, due to the harsh high-temperature environment, although high-temperature probes can withstand the high-temperature environment, the electronic components inside the high-temperature sensors are easily damaged by high temperatures. For example, electronic components such as capacitors, resistors, and integrated circuits on the electronic board are susceptible to thermal damage, which in turn affects the service life and accuracy of the high-temperature sensors, and can easily lead to malfunctions such as misjudgment or missed judgment.

[0003] Therefore, considering how to reduce the damage to the electronic components of high-temperature sensors caused by high-temperature environments in order to extend the reliable service life of temperature sensor components, we propose a high-temperature early warning external protection device. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A high-temperature warning external protection device, comprising:

[0007] Outer protective cover for detachable installation of temperature sensors;

[0008] The cooling protection unit includes a cold-storage aluminum fin disposed between the temperature sensor and the outer protective cover, and a semiconductor refrigeration chip installed outside the outer protective cover, the semiconductor refrigeration chip being used to provide a cooling source.

[0009] Preferably, the inner wall of the outer protective cover is provided with a thermal insulation layer.

[0010] Preferably, the bottom of the outer protective cover is provided with an opening, and heat-conducting fins are detachably installed below the opening.

[0011] Preferably, the thermoelectric cooler is detachably mounted on the side of the heat-conducting fins near the opening, and the cooling side of the thermoelectric cooler corresponds to the temperature sensor.

[0012] Preferably, a mounting plate is installed on the side of the heat-conducting fins away from the opening, and a cooling fan is installed on the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This high-temperature warning external protection device can provide a cooling atmosphere outside the temperature sensor through a cooling source, which can avoid the problem of the high temperature environment of thermal power plants damaging the electronic components of the sensor. In addition, the presence of cold storage aluminum fins can achieve a cold storage effect, avoiding continuous operation of the cooling source. Furthermore, the semiconductor refrigeration chip used as the cooling source is low in cost, easy to install and remove, practical, and conducive to maintaining the temperature sensor to obtain more reliable performance.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0025] The high-temperature warning external protection device in this embodiment specifically includes an external protective cover 2 that can be detachably installed outside the temperature sensor 1, such as... Figure 1 and Figure 2 The structure shown has an opening 21 at the bottom of the outer protective cover 2, and a semiconductor cooling chip 7 for providing a cooling atmosphere is installed at the opening 21.

[0026] However, the ambient temperature in thermal power plants is relatively high. In order to maintain the internal cooling atmosphere for a long time, this embodiment provides a heat insulation cotton layer on the inner wall of the outer protective cover 2 to maintain internal cooling. At the same time, in order to store cold, a cold storage aluminum fin 3 is installed between the temperature sensor 1 and the outer protective cover 2. That is, when the semiconductor refrigeration chip 7 is cooling, the cold storage aluminum fin 3 absorbs the cold source, and together with the heat insulation cotton layer, it provides a stable cooling atmosphere around the temperature sensor 1.

[0027] It should be noted that the thermoelectric cooler 7 cools on one side and heats up on the other, thus requiring heat dissipation. Therefore, a heat-conducting fin 4 is detachably installed below the port 21. Figures 3-5 As shown in the structure, a mounting plate 5 is installed on the side of the heat-conducting fin 4 away from the opening 21. A cooling fan 6 is installed on the mounting plate 5. The cooling fan 6 can provide airflow to dissipate heat from the heat-conducting fin 4. The semiconductor cooling chip 7 in this embodiment has a low cost and is easy to install and remove when mounted on the heat-conducting fin 4. Compared with the replacement of damaged temperature sensor 1, it can reduce the cost of use and has practicality.

[0028] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0029] Furthermore, if the embodiments of this utility model involve descriptions such as "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
