Abstract
Description
Technical field:
[0001] The utility model relates to a heat exchanger, in particular to a bellows heat exchanger with heat transfer enhancement effect, belonging to the technical field of bellows heat exchangers. Background technology:
[0002] The bellows heat exchanger is a device with significant heat transfer enhancement effect. Its working principle is based on the enhanced heat transfer theory and the unique wave crest and wave trough design. This design not only optimizes the heat transfer performance, but also breaks through the performance limitations of traditional shell-and-tube heat exchangers to a large extent. The bellows is made by special processing on the basis of ordinary heat exchange tubes. Both its inner and outer surfaces have concave and convex waveforms. This structure enables the bellows to enhance heat transfer both inside and outside the tube, achieving double-sided enhanced heat transfer effect.
[0003] During the operation of the bellows heat exchanger, strong turbulence will be generated when the medium flows inside and outside the tube, making it difficult for solids or suspended matter in the medium to settle. However, after long-term operation, some scale will inevitably form on the inner wall of the bellows. This scale will affect the heat exchange efficiency of the bellows heat exchanger and cause energy waste. The staff needs to clean it manually, which is troublesome. In addition, the scaling speed will be affected by the water quality, and the cleaning work often cannot be carried out in time. Therefore, a bellows heat exchanger with heat transfer enhancement effect is proposed. Utility model content:
[0004] The purpose of the utility model is to provide a bellows heat exchanger with heat transfer enhancement effect to solve one of the problems raised in the above background technology.
