[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] Example

[0025] Please refer to Figure 1-6 As shown, the utility model provides a technical solution: a convenient cooler capacity test temperature measuring instrument installation tool;

[0026] Four sets of temperature measuring resistor mounting bases 3 are fixedly installed at equal angles on the inner end of the steel pipe 1, a ball valve base 4 is fixedly installed on the inner end of the steel pipe 1, flanges 5 are fixedly installed on the upper and lower ends of the steel pipe 1, and mounting holes 6 are opened at equal angles on the inner end of the flange 5. A first internal thread 10 is provided at the inner end of the temperature measuring resistor mounting base 3, and a resistance thermometer 12 is threadedly connected to the inner end of the temperature measuring resistor mounting base 3. A second internal thread 11 is provided at the inner end of the ball valve base 4. Water outlets 7 are provided at the upper and lower ends of the steel pipe 1 to facilitate the installation and disassembly of the temperature measuring resistor. It is suitable for the testing of various types of air coolers and water coolers to ensure the smooth progress of the test and ultimately improve the working efficiency;

[0027] The guide member 2 is fixedly installed on the inner end of the steel pipe 1, and a diverter cone 8 is fixedly installed on the inner end of the guide member 2. Water flow holes 9 are opened at equal angles on the inner end of the guide member 2. The position angle of the water flow holes 9 corresponds to the installation angle of the temperature measuring resistor mounting base 3, and the temperature detection is more sufficient and accurate.

[0028] Specific working principle:

[0029] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, when using the portable cooler capacity test temperature measuring instrument installation tool, when testing the cooler, the tool is installed to the product inlet and outlet by passing the bolts through the installation hole 6 opened at the inner end of the flange 5, and the resistance thermometer 12 is installed on each corresponding temperature measuring resistor installation base 3. In order to ensure the accuracy of temperature data measurement, four temperature measuring resistor installation bases 3 are symmetrically distributed on the temperature measuring tool. The temperature measuring resistor installation bases 3 are distributed 45° across the center line and are perpendicular to each other. When installing this tool at the inlet, a straight pipe of about one meter needs to be installed at the front end of the tool. When installing the tool at the outlet, a connecting pipe is installed between the outlet and the tool to ensure the stability of the oil flow in the pipe;

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, when the liquid flows into the interior of the steel pipe 1, the diverter cone 8 disperses the liquid, allowing the liquid to flow through the interior of the water flow hole 9. Since the positions of the water flow holes 9 correspond to the temperature measuring resistor mounting bases 3, the resistance thermometer 12 is in full contact with the measured liquid, thereby increasing the stability and accuracy of the measurement. In addition, the pressure drop measurement pipeline can be connected to the steel pipe 1 using the ball valve base 4, so that the temperature and pressure drop can be measured at the same time. The above completes a series of operations for the installation tooling of the portable cooler capacity test temperature measuring instrument. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
