Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a reliable temperature measurement structure of an engine oil temperature sensor comprises a cover plate, wherein the bottom of the cover plate is fixedly connected with an external thread pipe, a heat transfer cylinder fixedly connected with the cover plate is arranged in the external thread pipe, and a mounting hole is formed in the middle of the cover plate and communicated with the heat transfer cylinder. The edge of apron is hexagon shape, facilitates the use spanner and screws up the operation.
The heat transfer cylinder comprises a first cylinder section and a second cylinder section, the first cylinder section is communicated with the mounting hole, the bottom of the second cylinder section is sealed and is formed by reducing the diameter of the first cylinder section, and the diameter of the second cylinder section is smaller than that of the first cylinder section. The position of the first cylinder section reducing to the second cylinder section and the bottom surface of the external threaded pipe are on the same plane, namely the length of the heat transfer cylinder is larger than that of the external threaded pipe.
The heat transfer cylinder is internally provided with a flexible connecting wire, the outer diameter of the flexible connecting wire is smaller than the inner diameter of the second cylinder section of the heat transfer cylinder, and the thermistor at the end part of the flexible connecting wire is in contact with the bottom of the second cylinder section. The clearance between first section of thick bamboo, second section of thick bamboo section and the flexible connecting line is filled sealed glue, joint cover is established at the silica gel pad 6 on the flexible connecting line in the mounting hole, the cooperation of sealed glue and silica gel pad can be effectively sealed and fixed the flexible connecting line of installing in the heat transfer section of thick bamboo, avoids the heat to run off, leads to the temperature measurement inaccurate. When measuring the temperature, the groove between the heat transfer cylinder and the external thread pipe is filled with engine oil inside and outside, the heat transfer cylinder conducts the temperature of the engine oil, and the heat is transferred to the thermistor in the heat transfer cylinder for temperature detection.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
