Description

TECHNICAL FIELD

[0001] The utility model relates to cooling technology field especially is related to a double cooling device. BACKGROUND

[0002] In many industrial production processes, a large amount of heat will be generated. If these heat is not removed in time, it will cause the equipment to overheat, affecting the normal operation and service life of the equipment. The shell and tube cooler can effectively transfer these heat to the cooling medium, so that the equipment can operate within the appropriate temperature range. For example, mechanical equipment: high temperature will reduce the material strength of mechanical parts, aggravate wear and tear, and deteriorate lubrication performance, thereby affecting the precision, reliability and service life of the equipment. Therefore, the cooler is widely used in chemical industry, metallurgy, mechanical manufacturing and other industries. Considering that a single shell and tube cooler failure or damage will result in poor cooling effect or no cooling effect, which will cause the temperature of the equipment used to rise, accelerate the high-temperature wear of the equipment, and affect the service life of the equipment. In order to solve the problems of temperature overheating, weather changes, and personnel inspection intensity, the device is invented. SUMMARY

One inlet is the inlet of hot fluid, and the hot fluid enters the tube side or shell side of the cooler through this inlet. The other inlet is the inlet of cooling medium (such as cooling water, air, etc.), and the cooling medium enters the cooler through this inlet to exchange heat with the hot fluid. Correspondingly, one outlet is the outlet of cooled hot fluid (i.e. the hot fluid outlet mentioned above), and the hot fluid with reduced temperature flows out of the cooler from this outlet after heat exchange. The other outlet is the outlet of heated cooling medium, and the cooling medium with increased temperature is discharged from the cooler after absorbing the heat of the hot fluid.

Its working principle is as follows: compressed air with a certain pressure enters a vortex nozzle and expands and accelerates, when the accelerated airflow enters a cylindrical vortex generator, the rotating airflow enters the inside of the heat pipe along the heat pipe wall, the airflow in the heat pipe is separated to produce energy after vortex exchange, the airflow is divided into two airflows, one is hot airflow, and the other is cold airflow. At the terminal of the heat pipe, part of the compressed air is discharged in the form of hot air through the adjusting valve, and the remaining compressed air returns to the center of the entering heat pipe rotating airflow at a lower speed, and the cold airflow is collected to the cold airflow end through the generator center to be discharged.

The timer is used for setting the working time of the machine, when the running time of the machine reaches the set value, the timer outputs a signal. The signal is transmitted to the comparator, and the comparator compares it with the preset threshold value. If the preset time is exceeded, the comparator triggers the alarm to issue an alarm.

[0010] Further, the to-be-cooled fluid container comprises an oil tank and a bearing seat, the oil tank and the bearing seat are connected through pipelines, the oil outlet end of the bearing seat is connected with the hot fluid inlet of the tube cooler through a pipeline, and the hot fluid outlet of the tube cooler is connected with the inlet of the oil tank through a pipeline.
