[0002] Vehicle air conditioning mufflers are primarily used to reduce noise generated during the operation of the air conditioning system, improving the comfort of drivers and passengers. Through special internal acoustic structures and materials, they effectively absorb or reflect sound waves, thereby reducing noise propagation.

[0003] With the development of the automotive industry, consumers have increasingly higher demands for vehicle comfort, including the control of air conditioning noise. Traditional air conditioning systems often neglect noise issues during design, resulting in significant noise during operation and affecting the comfort of passengers. To solve this problem, in-vehicle air conditioning mufflers have emerged. Summary of the Invention

[0004] Based on the above, this application provides a muffler for automotive air conditioning systems that has good noise reduction effect, stable internal structure of the muffler housing, and facilitates noise reduction and heat dissipation.

[0007] The carrier box is equipped with seven sets of sound-absorbing baffles. The sound-absorbing baffles are installed obliquely along the grid of the inner wall of the carrier box. The baffles are evenly distributed with raised particles on the arc plate that fits against the inner wall of the carrier box.

[0008] The carrier box is filled with a sound-absorbing filling layer along its left and right ends.

[0009] Furthermore, the root end of the valve head is connected to the cooling port, and the cooling port is fixedly connected to the bent section of the edge of the sound-absorbing baffle.

[0010] Furthermore, the bent section of the sound-absorbing folding plate edge and the flow-guiding folding edge are integrally connected, the side of the flow-guiding folding edge is in contact with the grid limit, and the grid is integrally connected with the inner wall of the carrier box.

[0011] Furthermore, two sets of padding layers are attached to the outer wall of the carrier box along the left and right ends. Fixing bolts are inserted into the surface of the padding layers and extend into the carrier box. The inserted fixing bolts are fixedly connected to the sound-absorbing filling layer.

[0012] Furthermore, the carrier box is equipped with an insert edge along the edge of the padding layer, and the insert edge makes contact with the padding layer for limiting.

[0013] Furthermore, the inner wall of the carrier box retains a sound-absorbing layer.

[0014] The beneficial effects of this utility model are as follows:

[0015] Compared with the prior art, this utility model adopts an external valve body cooling end head combined with a noise reduction and heat dissipation supply to introduce the heat generated by noise reduction to the heat dissipation point, thereby avoiding local overload of the noise reduction box; the built-in filling pad layer serves as the head and tail noise reduction and sealing material, and the noise reduction folding plate is combined with the grid for auxiliary installation, which can also stabilize the internal structure of the box.

Detailed Implementation

[0020] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0021] like Figure 1 and Figure 2 As shown, a muffler for an automotive air conditioning system includes a carrier box and pipe connection ports; two sets of pipe connection ports 2 are installed on the left and right ends of the carrier box 1, and valve heads 4 are installed on the front and rear ends of the carrier box 1; wherein, the carrier box 1 serves as the carrier of the muffler, and the air conditioning pipe connection installation process is completed through the pipe connection ports 2, and the valve heads 4 installed at the front and rear of the carrier box 1 can cooperate to guide the internal heat flow and dissipate heat.

[0022] The housing 1 is equipped with seven sets of sound-absorbing baffles 7. These baffles 7 are installed at an angle along the inner wall grid of the housing 1. The curved surfaces of the baffles 7 that conform to the inner wall of the housing 1 have evenly distributed raised particles. The installation structure of the baffles 7 allows them to fit snugly against the housing 1, and their angled installation along the inner wall grid allows for more effective noise absorption. The raised particles increase the contact area of ​​the noise waves, thus improving the sound absorption effect.

[0023] The carrier box 1 is filled with a sound-absorbing filling layer 8 along its left and right ends. The sound-absorbing filling layer 8 serves as the encapsulation and sound-absorbing structure for the front and rear ends.

[0024] like Figure 1 and Figure 2 As shown, the root end of the valve head 4 is connected to the cooling port 6, and the cooling port 6 is fixedly connected to the bent section of the edge of the sound-absorbing baffle 7. The cooling port 6, together with the sound-absorbing baffle 7, serves as a heat-conducting structure, allowing heat to be introduced into the valve head 4 via the cooling port 6.

[0025] like Figure 1 and Figure 2 As shown, the bent section of the edge of the sound-absorbing baffle 7 and the guide edge 9 are integrally connected. The side of the guide edge 9 is in limiting contact with the grille 10, and the grille 10 is integrally connected with the inner wall of the carrier box 1. The grille 10 serves as an auxiliary installation structure, while the guide edge 9 completes the guiding installation process along the grille 10.

[0026] like Figure 1 and Figure 2 As shown, two sets of padding layers 5 are attached to the outer wall of the carrier box 1 along the left and right ends. Fixing bolts 3 are inserted into the surface of the padding layers 5, extending into the carrier box 1 and fixedly connected to the sound-absorbing filling layer 8. The external mounting structure of the fixing bolts 3 improves the ease of later maintenance of the equipment.

[0027] like Figure 1 and Figure 2 As shown, the carrier box 1 is equipped with an insert edge 12 along the filling edge of the padding layer 5, and the insert edge 12 makes limiting contact with the padding layer 5. The insert edge 12, together with the padding layer 5, serves as an auxiliary structure for positioning and preventing displacement.

[0028] like Figure 1 and Figure 2 As shown, the inner wall of the carrier box 1 retains a sound-absorbing layer 11.
