Problems solved by technology

At present, the use of sound-absorbing sheets can play a certain role in sound-absorbing. The fin structure on the main body of the existing sound-absorbing sheets is asymmetrical, unstable in the main water pipe, and has no obvious effect on turbulence.
However, during the manufacturing process of the product, the sound-absorbing sheet will affect the installation of the R tube, making the installation quality of the R tube unstable
Analyze the reasons for the unstable installation quality of the R tube. Because the contact surface between the sound-absorbing plate and the R-tube is not large enough, the contact between the R-tube and the sound-absorbing plate is asymmetrical.

Embodiment Construction

[0027] see Figure 1 ~ Figure 4 , The stainless steel sound-absorbing sheet of this embodiment includes a stainless steel main body 2 with an interference hole 1, and several sets of stainless steel interference fin groups 3 distributed equidistantly along the length direction of the stainless steel main body. Each group of stainless steel interference fins has two top stainless steel interference fins 4 and two bottom stainless steel interference fins 5 respectively mounted on the top and bottom of both sides in the width direction of the stainless steel body.

[0028] see figure 1 , figure 2 , Figure 4 , There are cutting fins 6 symmetrically installed on both sides of the stainless steel main body between adjacent interference holes on the stainless steel main body.

[0029] see figure 1 , the angle α between adjacent cutting fins in the middle of the stainless steel main body is 160°. The angle β between the cut fin in the middle and the length direction of the stai...

Abstract

The invention discloses a stainless steel silencing sheet which is used in a main water tube of a household gas water heater or a main water tube of a wall-hanging stove heat exchanger. The stainless steel silencing sheet comprises a stainless steel main body with disturbance holes, and a plurality of stainless steel disturbance fin groups which are distributed at equal distance in the length direction of the stainless steel main body; and two top stainless steel disturbance fins and two bottom stainless steel disturbance fins which are separately arranged on tops and bottoms of two side surfaces in the length direction of the stainless steel main body are arranged in each stainless steel disturbance fin groups group. The stainless steel silencing sheet is good in silencing effect, is high in heating efficiency, and improves R tube mounting quality and stability.

Description

Technical field: [0001] The invention relates to a stainless steel sound-absorbing sheet used in the main water pipe of a domestic gas water heater or the main water pipe of a wall-hung furnace heat exchanger. Background technique: [0002] An important indicator to measure the quality of domestic gas water heater products is its noise value. According to GB6932-2001, the noise requirement of gas water heater products is below 65dB. The main noises of gas water heaters: mechanical noise, aerodynamic noise, water flow noise, combustion noise. [0003] The gas water heater is a connected body composed of cold water pipes and hot water pipes. When the gas is burned, it releases heat and absorbs heat through the heat collecting fins. The heat from the heat collecting fins is transferred to the heat collecting pipes to heat the water. Due to the existence of the heat exchanger coil of the gas water heater, water hammer impact noise will be generated when the water flow passes by...
