Problems solved by technology

[0002] Conventional cooler coils mostly use single-layer winding, so that the cooling effect of the cooler is low. In order to improve the cooling effect, the current solution is to place two coils side by side in one cooler. On the premise of the same heat exchange area However, the above-mentioned structure is large in size, high in cost, inconvenient for maintenance and operation, and two coils are arranged side by side in the same cooler, which cannot be wound and formed at one time. Welding is required between the coils, which does not meet the requirement that the cooler coils cannot be connected.
In addition, water vapor sampling equipment currently achieves cooling effects by increasing the number of coolers and setting up pre-cooling devices. The arrangement of high-temperature racks is too crowded, and operation and maintenance are difficult

Embodiment Construction

[0013] The structural principle and working principle of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 , a double-layer coil cooler, including a cooler cylinder 4, a cooling water inlet 6 and a cooling water outlet 3 arranged on the cooler cylinder 4, and a double-layer coil is installed in the cooler cylinder 4 5. The double-layer coil 5 is an inner and outer layer structure wound by a pipe. The outer layer interface 1 of the outer layer structure extends out of the cooler cylinder 4 to connect to the cooling water inlet, and the inner layer interface 2 extends out of the cooling water The cylinder body 4 is connected to the cooling water outlet. In this embodiment, the double-layer coil 5 is a cylindrical helical structure with two inner and outer layers, the outer coil is a right-handed cylindrical helical structure, the inner coil is a left-handed cylindrical helical structure, the out...

technical field [0001] The invention relates to the technical field of coolers, in particular to a double-layer coil cooler. Background technique [0002] Conventional cooler coils mostly use single-layer winding, so that the cooling effect of the cooler is low. In order to improve the cooling effect, the current solution is to place two coils side by side in one cooler. On the premise of the same heat exchange area However, the above-mentioned structure is large in size, high in cost, inconvenient for maintenance and operation, and two coils are arranged side by side in the same cooler, which cannot be wound and formed at one time. Welding is required between the coils, which does not meet the requirement that the cooler coils cannot be connected. . In addition, water vapor sampling equipment currently achieves cooling effects by increasing the number of coolers and setting up pre-cooling devices. The arrangement of high-temperature racks is too crowded, making operation a...
