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

Example Embodiment

[0013] The structure and working principles 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, comprising a cooler barrel 4, a cooling water inlet 6 and a cooling water outlet 3 arranged on the cooler barrel 4, and a double-layer coil is installed in the cooler barrel 4 5. The double-layer coil 5 is an inner and outer layer structure wound by a pipe. The outer interface 1 of the outer structure extends out of the cooler cylinder 4 to connect to the cooling water inlet, and the inner interface 2 extends out for cooling. The cylinder 4 is connected to the cooling water outlet. In this embodiment, the double-layer coil 5 has an inner and outer cylindrical spiral structure, the outer coil has a right-handed cylindrical spiral structure, the inner coil has a left-handed cylindrical spiral structure, and the outer interface 1 and the inner layer The interface 2 is arrang...

Abstract

The invention discloses a double-layer coiled pipe cooler, comprising a cooler cylinder body, and a cooling water inlet and a cooling water outlet arranged on the cooler cylinder body, wherein a double-layer coiled pipe is installed in the cooler cylinder body, the double-layer coiled pipe is of a structure with an inner layer and an outer layer formed by winding one pipe, the outer layer interface of the outer layer structure extends out of the cooler cylinder body to be connected with the cooling water inlet, and the inner layer extends out of the cooler cylinder body to be connected with the cooling water outlet; according to the double-layer coiled pipe cooler provided by the invention, the heat exchange performance of the cooler can be enhanced, the equipment space can be saved, and the material cost can be reduced.

Description

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...
