Abstract

The invention relates to a flow disturbing piece, a heat exchange assembly and a heat exchange device. The flow disturbing piece comprises a flow disturbing plate, the flow disturbing plate is a spiral plate and is used for being arranged in a heat exchange tube in the axial direction of the heat exchange tube, and at least one side plate edge of the flow disturbing plate is provided with a plurality of piercing parts and / or a plurality of through holes; the flow disturbing plate is a spiral plate and has a good flow disturbing effect on water flow in the heat exchange tube, so that the temperature of all positions in the heat exchange tube is uniform as much as possible, the temperature difference of water in all positions in the heat exchange tube is very small, the phenomenon that the temperature of the tube wall of the heat exchange tube is higher than the saturation temperature of water is avoided, and therefore the purposes of reducing bubbles and eliminating vaporization noise are achieved; in addition, the piercing parts can pierce bubbles when making contact with the bubbles in the water flow at the tube wall, and the individual density of a bubble group can be reduced so that vaporization noise can be reduced; and the through holes formed in the edge of the flow disturbing plate can further enhance the flow disturbing effect, so that the temperature of all positions in the heat exchange tube is uniform as much as possible, the bubbles can be reduced, and vaporization noise is eliminated.

Description

technical field [0001] The invention relates to the technical field of hot water equipment, in particular to a spoiler, a heat exchange component and a heat exchange device. Background technique [0002] With the improvement of the quality of life, gas-fired water heaters are gradually popularized in the daily life of every household. Gas-fired water heaters are, for example, gas water heaters and gas heating water heaters. Traditionally, the main sources of noise for gas water heating equipment are combustion noise, vaporization noise, fan noise and waterway noise. Among them, vaporization noise accounts for a large proportion. The vaporization noise can reach about 73db in laboratory tests, far exceeding the national standard of 65db. Consumer experience is very poor. Therefore, various manufacturers are also working hard to reduce vaporization noise and improve user experience. [0003] In order to reduce the noise of gas-fired hot water equipment, the current industry u...
