like image 3 Shown: Finned heat exchanger with large fin pitch (10mm fin pitch), processed image 3 Products with such a large film distance need other auxiliary methods to ensure the film distance. The original practice in the industry is to insert spacers such as wooden strips or other plastic rods between the films, such as Figure 4 shown, but this is very inefficient

The invention discloses a finned tube heat exchanger made with a serial tube jig. The finned tube heat exchanger comprises a heat exchanger body and the serial tube jig; the heat exchanger body comprises copper tubes, an upper cover plate, a lower cover plate, a heat supply effluent iron header, a heat supply backwater iron header, support steel bars, a tube plate, high speed steel fins and headerreinforcing plates; the serial tube jig comprises a jig body and a workbench; the jig body comprises a bottom spacing plate, a side spacing plate a and a side spacing plate b, and the side spacing plate a and the side spacing plate b are arranged on the both sides of the bottom spacing plate separately; the workbench comprises a frame body which is provided with a working table and a placement platform, and the working table is provided with a guide rail; and the jig body is installed on the workbench through cooperation of a guide rail slot and the guide rail. The high speed steel fins madewith the serial tube jig are good in heat dissipation performance and long in service life, and the product quality is improved.
Description
technical field [0001] The invention relates to a heat exchanger, in particular to a finned heat exchanger manufactured by using a series tube jig. Background technique [0002] Under the national policy of canceling small boilers, there are three types of heat supply: air source heat pumps, gas boilers, and electric heat storage boilers. Electric thermal storage boilers are widely used in northern regions, because the performance of air source heat pumps drops significantly below minus 20 degrees, and it is easy to frost. Therefore, it is very good to use electric thermal storage boilers in cold northern regions. The earliest electric heat storage boiler heat exchanger used a shell-and-tube heat exchanger, which had low efficiency and large volume. Therefore, finned heat exchangers are more popular now. [0003] The fins of the heat exchanger are mainly to increase the heat exchange area. When the evaporating temperature of the evaporator is different, the spacing of the...
