[0026] Please refer to the reference. Figures 1 to 5 This utility model embodiment provides a heat exchanger 100 for heat exchange. It enables the rapid installation and fixation of the first filter element 120, simplifies the installation process, improves installation efficiency, and ensures that it is not easily loosened after installation, making it stable and reliable.

[0027] The heat exchanger 100 includes a first manifold 110, a first filter element 120, and a drying cylinder 130. The first manifold 110 and the drying cylinder 130 are arranged side by side and connected to each other. The side wall of the first manifold 110 has a first through hole 111, and the side wall of the drying cylinder 130 has a second through hole 131. The first through hole 111 and the second through hole 131 are aligned and connected, allowing the heat exchange medium in the first manifold 110 and the drying cylinder 130 to flow to each other. That is, the heat exchange medium in the first manifold 110 can flow to the drying cylinder 130, and the heat exchange medium in the drying cylinder 130 can also flow to the first manifold 110, so as to realize the heat exchange function. Specifically, the first filter element 120 is provided with a first hook 121. The first filter element 120 extends into the first through hole 111 or the second through hole 131, that is, the first filter element 120 is placed inside the first collector pipe 110 or the drying cylinder 130. The first hook 121 is clamped between the first collector pipe 110 and the drying cylinder 130. The first collector pipe 110 and the drying cylinder 130 work together to clamp and fix the first hook 121, thereby fixing the first filter element 120. In this way, the first filter element 120 can be quickly installed and fixed, simplifying the installation process, improving installation efficiency, and ensuring that it is not easily loosened after installation, making it stable and reliable.

[0028] In this embodiment, the first filter element 120 extends into the second through hole 131, that is, the first filter element 120 is placed inside the drying cylinder 130. However, it is not limited to this. In other embodiments, the first filter element 120 can also extend into the first through hole 111. In this case, the first filter element 120 is placed inside the first collector pipe 110.

[0029] Furthermore, a boss 132 protrudes outward from the side wall of the drying cylinder 130, and a second through hole 131 is opened on the boss 132. The first hanging ear 121 is clamped between the boss 132 and the first collecting pipe 110. The side wall of the first collecting pipe 110 and the boss 132 work together to clamp and fix the first hanging ear 121 to prevent the first filter element 120 from loosening.

[0030] In this embodiment, the boss 132 is provided with a limiting groove 133, which is connected to the second through hole 131. The first hanging ear 121 is disposed in the limiting groove 133. The boss 132 can limit the first hanging ear 121 through the cooperation of the first hanging ear 121 and the limiting groove 133, thereby limiting the first filter element 120 and further preventing the first filter element 120 from loosening.

[0031] In this embodiment, the boss 132 is provided with an mounting arc surface 134, and a limiting groove 133 is formed on the mounting arc surface 134. The curvature of the mounting arc surface 134 is the same as the curvature of the cross-section of the first collector pipe 110. The side wall of the first collector pipe 110 is fitted to the mounting arc surface 134 to ensure the stability of the connection between the first collector pipe 110 and the drying cylinder 130. Specifically, the side wall of the first collector pipe 110 is welded to the mounting arc surface 134 to fix the relative position of the first collector pipe 110 and the drying cylinder 130, prevent the first collector pipe 110 from shifting relative to the drying cylinder 130, and ensure the clamping and fixing effect of the first hanging ear 121 to prevent the first filter element 120 from loosening.

[0032] The drying cylinder 130 includes a cylinder body 135, a first plug 136, and a second plug 137. A boss 132 is located on the outside of the cylinder body 135. The first plug 136 and the second plug 137 are positioned opposite each other at both ends of the cylinder body 135 and are connected to the cylinder body 135 to form a sealed cavity, preventing leakage of the heat exchange medium. Specifically, both the first plug 136 and the second plug 137 are interference-fitted with the cylinder body 135 and are welded to the cylinder body 135 to improve connection strength and sealing performance.

[0033] In this embodiment, the wall thickness of the cylinder 135 is 1.8mm-2.3mm, while the wall thickness of the drying cylinder in the prior art is at least 2.5mm because it needs to be threaded with the threaded plug. Compared with the prior art, the wall thickness of the drying cylinder 130 in this utility model is thinner, the manufacturing cost is lower, and it has a lightweight effect.

[0034] The first filter element 120 includes a connecting portion 122 and a filter screen portion 123. The connecting portion 122 is connected to the filter screen portion 123. A first hook 121 is disposed at the end of the connecting portion 122 away from the filter screen portion 123. The first manifold 110 and the drying cylinder 130 can be fixed to the connecting portion 122 via the first hook 121, thereby fixing the filter screen portion 123. The filter screen portion 123 is used to filter and remove impurities from the heat exchange medium passing through the first through hole 111 and the second through hole 131. In this embodiment, the connecting portion 122 is made of aluminum and the filter screen portion 123 is made of stainless steel, but it is not limited to these materials. In other embodiments, the connecting portion 122 and the filter screen portion 123 may also be made of other materials, and the materials of the connecting portion 122 and the filter screen portion 123 are not specifically limited.

[0035] Furthermore, the cross-section of the first filter element 120 is oblong or circular, and the shapes of the first through hole 111 and the second through hole 131 are adapted to the shape of the first filter element 120 to ensure the communication effect of the first through hole 111 and the second through hole 131, and to ensure that the first filter element 120 can effectively filter the heat exchange medium passing through the first through hole 111 and the second through hole 131, resulting in a good filtration effect.

[0036] Furthermore, there are multiple first through holes 111 and multiple second through holes 131. The multiple first through holes 111 are spaced apart along the axial direction of the first manifold 110, and each first through hole 111 communicates with one second through hole 131. In this embodiment, there are two first through holes 111 and two second through holes 131. The two first through holes 111 are spaced apart along the axial direction of the first manifold 110, and each first through hole 111 communicates with one second through hole 131. Specifically, the heat exchange medium in the first manifold 110 can flow into the drying cylinder 130 through the first first through hole 111 and the first second through hole 131, and the heat exchange medium in the drying cylinder 130 can flow into the drying cylinder 130 through the second second through hole 131 and the second first through hole 111. The first filter element 120 extends into the first second through hole 131 to facilitate the storage of filtered impurities.

[0037] Optionally, the heat exchanger 100 further includes a second manifold 140 and a plurality of flat tubes 150. The first manifold 110 and the second manifold 140 are arranged in parallel and spaced apart, and the plurality of flat tubes 150 are arranged in parallel and spaced apart, and are all connected between the first manifold 110 and the second manifold 140. The heat exchange medium in the first manifold 110 and the second manifold 140 can flow to each other through the plurality of flat tubes 150, that is, the heat exchange medium in the first manifold 110 can flow to the second manifold 140, and the heat exchange medium in the second manifold 140 can also flow to the first manifold 110, so as to realize the heat exchange function.

[0038] Optionally, the heat exchanger 100 further includes a connecting flange 160 and a second filter element 170. The connecting flange 160 is connected to the outside of the side wall of the second manifold 140. The side wall of the second manifold 140 has a third through hole (not shown), and the connecting flange 160 has a fourth through hole (not shown). The third through hole and the fourth through hole are aligned and communicate with each other, allowing the heat exchange medium in the connecting flange 160 and the second manifold 140 to flow to each other. That is, the heat exchange medium in the connecting flange 160 can flow to the second manifold 140, and the heat exchange medium in the second manifold 140 can also flow to the connecting flange 160, so as to realize the heat exchange function. Specifically, the second filter element 170 is provided with a second hook (not shown in the figure). The second filter element 170 extends into the third or fourth through hole, that is, the second filter element 170 is placed inside the connecting flange 160 or the second manifold 140. The second hook is clamped between the second manifold 140 and the connecting flange 160. The second manifold 140 and the connecting flange 160 work together to clamp and fix the second hook, thereby fixing the second filter element 170. Similarly, this allows for quick installation and fixing of the second filter element 170, simplifying the installation process, improving installation efficiency, and ensuring that it is not easily loosened after installation, making it stable and reliable.

[0039] In this embodiment, there are two connecting flanges 160, each with a fourth through hole and two third through holes. The two third through holes are spaced apart along the axial direction of the second manifold 140, and the fourth through hole of each connecting flange 160 communicates with one of the third through holes. Specifically, the heat exchange medium can enter the second manifold 140 through the fourth through hole and the first third through hole of the first connecting flange 160, and the heat exchange medium in the second manifold 140 can be discharged outward through the second third through hole and the fourth through hole of the second connecting flange 160. The second filter element 170 extends into the first third through hole to facilitate the storage of filtered impurities.

[0040] In this embodiment, the specific structure and installation method of the second filter element 170 are the same as those of the first filter element 120, and will not be described again here.
