Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

As shown in fig. 1-2, a small flow rate air cooling system for small sites comprises:

an integral frame 1;

the four upright posts 2 are fixed at the bottom of the integral frame 1;

the method is characterized in that: the heat exchanger is characterized in that a fan 3 fixed on a stand column 2 is arranged in the integral frame 1, the bottom of the fan 3 is connected with a motor 4, a tube bundle 5 is arranged at the top of the integral frame 1, an inlet tube box 6 is arranged in the tube bundle 5 close to the top end, an outlet tube box 7 is arranged in the tube bundle 5 close to the bottom end, and a U-shaped heat exchange tube 8 which is obliquely arranged is connected between the inlet tube box 6 and the outlet tube box 7.

In the structure, the top of the inlet channel box 6 is connected with a vent valve 9 positioned on the top end surface of the tube bundle 5, and the vent valve 9 is higher than the top end of the U-shaped heat exchange tube 8.

In the structure, the bottom of the outlet pipe box 7 is provided with a drain valve 10 positioned on the bottom end surface of the pipe bundle 5, and the drain valve 10 is lower than the bottom end head of the U-shaped heat exchange pipe 8.

In the structure, the U-shaped heat exchange tube 8 is formed by bending a steel tube.

The utility model is suitable for the small-flow air cooling system in a small place, the whole equipment is integrated on the whole frame, the structure is compact, the volume is small, and the fan, the motor and the tube bundle are arranged on the whole frame. Structurally, the overall equipment is removed from complex design, is overall concise and compact, can be transported integrally in transportation, is not required to be installed on site, can be replaced at any time according to requirements without being disassembled, saves installation cost, and can save space. The tube bundle, the inlet tube box and the outlet tube box are made of seamless tubes. Compared with a plate-type pipe box, the pipe box in the form is more excellent in pressure bearing, is smaller and more exquisite in structure, and is more suitable for occasions with small occupied space. The heat exchange tubes in the tube bundle adopt U-shaped heat exchange tubes which are integrally inclined, the inclined design is favorable for heat exchange effect, and condensate in the tubes can be prevented from flowing back when the medium is condensed, so that the U-shaped heat exchange tubes are prevented from being frost-cracked in winter, and accumulated liquid can be discharged through a drain valve. Meanwhile, the U-shaped heat exchange tube is formed by bending a steel tube, the traditional welding mode is abandoned at the bent tube, and the whole tube is processed by special cold bending, so that the problems of leakage and the like caused by welding reasons are solved.

When the small-flow air cooling system suitable for a small place is used specifically, firstly, the electrical components attached to the system are connected with the control switch and the power supply which are matched with the electrical components, the motor drives the fan to work, after the fan works normally, a medium enters the U-shaped heat exchange tube from the inlet tube box, flows along the heat exchange tube with the inclined arrangement, then enters the outlet tube box, and flows out from the outlet of the outlet tube box. After the equipment is used for a period of time, a drain valve at the lower part of the outlet pipe box is opened periodically to remove impurities or accumulated liquid in the drain valve.
