Benefits of technology

"The present invention is a heat exchanger with a cleaning device that removes dirt and dust from the heat exchange tubes. The cleaning device has scraping members and a moving board with receiving holes for the scraping members. There are also blocking boards to restrict the movement of the scraping members. The heat exchange tubes are surrounded by a watering device with spraying pipes to cool the tubes and prevent the buildup of dirt. The cleaning device and the watering device work together to improve the heat exchange efficiency, save energy, and prolong the life of the apparatus."

Problems solved by technology

However, dirt or dust is likely to be accumulated in such heat exchangers after a long period of use, as a result, the efficiency of heat transmission is reduced, the energy is reduced largely and the cost is increased.
However, the structure of such a brush is complex and the heat energy produced by such a heat exchanger is increased.

Embodiment Construction

[0018]Referring to FIGS. 1-3, a heat exchanger in accordance with the present invention is a heat exchange device 10 which comprises a laminated front positioning board 11, a laminated rear positioning board 12 and a plurality of parallel heat exchange tubes 13. The front positioning board 11 and the rear positioning board 12 are provided for insertion of both ends of each heat exchange tube 13, and the heat exchange tubes 13 are inserted into a cleaning device 20.

[0019]Referring to FIGS. 2-4, the cleaning device 20 comprises a laminated moving board 21, a plurality of circular-shaped scraping members 22 and at least two rectangular-shaped blocking boards 23. The moving board 21 is defined with a plurality of penetrated receiving holes 210 for receiving the scraping members 22. In a center of each scraping member 22 is defined a through hole 220 for insertion of the heat exchange tube 13. The blocking boards 23 are fixed to both sides of the moving board 21 and are provided for rest...

Abstract

A heat exchanger comprises a plurality of heat exchange tubes inserted into a cleaning device. The cleaning device has the effect of movably scraping the dirt or dust accumulated in an outer side of each heat exchange tube, and a watering device is provided for spraying water to lower the temperature of the heat exchange tubes and to clean the heat exchange tubes. The cleaning device cooperates with the watering device to scrap the dirt or dust accumulated in the heat exchange tubes, clean and lower the temperature of the heat exchange tubes, so as to prevent the dirt or dust from being accumulated in the heat exchange tubes, improve the radiating effect of the heat exchange tubes and save the energy.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a heat exchanger, and more particularly to a heat exchanger which can improve the efficiency of heat transmission.[0003]2. Description of the Prior Art[0004]Currently, heat exchangers are widely used in different kinds of apparatuses or systems, such as automotive industry apparatus, ordinary air conditioners or cooling systems, and are divided into water-cooled heat exchanger and air-cooled heat exchanger. The common water-cooled heat exchanger, such as shell and tube heat exchanger and coil heat exchanger. However, dirt or dust is likely to be accumulated in such heat exchangers after a long period of use, as a result, the efficiency of heat transmission is reduced, the energy is reduced largely and the cost is increased. Therefore, the author of this present invention has invented a heat exchanger with a cleaning device.[0005]The heat exchanger with a cleaning device described in TW P...
