Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a wave-shaped water chamber of a radiator. Background Art

[0002] A radiator is a device used to remove heat generated by internal combustion engines, electrical equipment, etc. It is very common in automobiles, computers, and various industrial applications. Among them, the automobile radiator consists of a water inlet chamber, a water outlet chamber, and a radiator core. The coolant flows in the radiator core, and the air passes outside the radiator. The hot coolant cools down due to the heat dissipation to the air, and the cold air heats up due to the heat dissipated by the coolant.

[0003] The water chamber is one of the key components of the radiator, and its function is to serve as the inlet and outlet of the cooling fluid and to ensure that the coolant flows evenly through the fins. The water chamber is usually made of plastic because plastic has relatively low manufacturing cost, light weight and good corrosion resistance.

[0004] The patent with publication number CN217818325U previously applied by the applicant discloses a water chamber structure of an automobile heat exchanger, which includes a joint and a water chamber body with an opening at one end. The water chamber body includes a water chamber main board and a water chamber bottom shell with a U-shaped cross-section. A second arc transition section is provided at the lower edge of the water chamber bottom shell. A plurality of concave reinforcing ribs are provided on the second arc transition section. This reinforcing rib structure only greatly improves the strength of the second arc transition section, but has limited improvement on the strength of the side wall and the bottom wall of the water chamber bottom shell. Especially when the length of the water chamber bottom shell is long, its side wall and the bottom wall are prone to deformation. Utility Model Content

[0009] Preferably, the bottom shell portion includes an arc-shaped bottom wall, a front side wall and a rear side wall, and the arc-shaped bottom wall is gradually opened toward the frame portion.

[0010] Preferably, a first arc-shaped transition section is provided at the connecting position between the arc-shaped bottom wall and the front side wall and the rear side wall.

[0011] Preferably, the length of the frame portion is greater than the maximum width of the bottom shell portion, the length of the frame portion is greater than the maximum length of the bottom shell portion, and the thickness of the frame portion is greater than the thickness of the bottom shell portion.

[0013] Preferably, a second arc-shaped transition section is provided on the inner edge of the upper end surface of the opening.

[0014] The beneficial effects of the utility model are as follows: in the utility model, a wave-shaped continuous reinforcing rib structure is arranged on the bottom shell portion, and the reinforcing rib structure fully covers the bottom shell portion, thereby greatly improving the overall strength of the water chamber body and extending its service life.

[0025] Embodiment 1:

[0026] like Figures 1 to 5 As shown, a wavy water chamber of a radiator includes a water chamber body 1 for being assembled with a radiator core, the water chamber body 1 is provided with a medium outlet and a medium inlet, the water chamber body 1 includes a frame portion 2 and a bottom shell portion 3 with a U-shaped cross section, continuous reinforcing rib structures 4 are arranged at intervals along the length direction on the bottom shell portion 3, and the projection height of the reinforcing rib structure 4 in the height direction is not less than half of the projection height of the bottom shell portion 3 in the height direction, as shown in FIG. Figure 2 As shown, the projected height of the reinforcing rib structure 4 in the height direction is h, and the projected height of the bottom shell portion 3 in the height direction is H.

[0027] Through the above arrangement, the water chamber main body 1 is integrally injection molded. By arranging a wave-shaped continuous reinforcing rib structure 4 on the bottom shell portion 3, and the reinforcing rib structure 4 fully covers the bottom shell portion, the overall strength of the water chamber main body 1 is greatly improved and its service life is extended. Even if the length of the water chamber main body 1 is long, it can ensure that no large deformation occurs, which is conducive to injection molding production and assembly with the radiator core.

[0028] In this embodiment, the dimension of the reinforcing rib structure 4 along the length direction of the bottom shell portion 3 is not less than half of the distance between the two adjacent reinforcing rib structures 4. Figure 2 As shown, the dimension of the reinforcing rib structure 4 along the length direction of the bottom shell portion 3 is W2, and the distance between the two adjacent reinforcing rib structures 4 is W1, so that the reinforcing rib structure 4 is easy to demold during injection molding, and the wider reinforcing rib structure 4 reduces the difficulty of manufacturing the injection mold.

[0029] Furthermore, the reinforcing rib structure 4 protrudes toward the inner cavity of the bottom shell portion 3, and the edge thereof has a smooth transition with the bottom shell portion 3. The smooth transition can reduce stress concentration, avoid product fatigue and cracking, and reduce the difficulty of demoulding, improve the structural strength of the product, and thus extend the service life of the product. Of course, the reinforcing rib structure 4 is not limited to protruding toward the inner cavity, but can also protrude outward.

[0030] Furthermore, the bottom shell portion 3 includes an arc-shaped bottom wall 31, a front side wall 32 and a rear side wall 33. The arc-shaped bottom wall 31 is gradually opened toward the frame portion 2. The arc-shaped bottom wall 31 has no dead angle, which is easier to clean. It also helps guide the flow of the coolant and reduces turbulence and fluid resistance. In addition, the open setting is easier to demould than the parallel setting.

[0031] Furthermore, the arc-shaped bottom wall 31 and the connection position between the front side wall 32 and the rear side wall 33 are provided with a first arc-shaped transition section 5, forming a smooth curvature, which increases the durability and life of the structure. Secondly, in the plastic injection molding process, the arc-shaped transition section is easier to mold than the right-angle connection, and the thickness of the molded product is uniform and the strength is better.

[0032] Secondly, the four corners of the frame body 2 are provided with rounded portions 8, and the radius of the first arc-shaped transition section 5 is not less than the radius of the rounded portion 8, thereby avoiding sharp corners, improving the strength of the structure, and preventing material fatigue or fracture caused by stress concentration at these connection points.

[0033] Furthermore, the length of the frame portion 2 is greater than the maximum width of the bottom shell portion 3, the length of the frame portion 2 is greater than the maximum length of the bottom shell portion 3, and the thickness of the frame portion 2 is greater than the thickness of the bottom shell portion 3, which can better resist bending force and improve the connection strength and reliability when the water chamber main body 1 and the radiator core are assembled.

[0034] Furthermore, an opening 21 is provided on the frame portion 2, and a guide portion 221 is provided in the opening 21 which is contracted toward the bottom shell portion 3 to facilitate assembly with the radiator core. A second arc-shaped transition section 222 is provided on the inner edge of the upper end surface of the opening 21. Since this end surface will be connected to the radiator core, the second arc-shaped transition section 222 can prevent damage to the radiator core due to sharp edges.

[0035] Furthermore, a plurality of positioning posts 6 are provided on the bottom shell portion 3 so as to enable correct alignment during assembly. At least one boss 7 is provided at the bottom end of the bottom shell portion 3 so that the U-shaped bottom shell portion 3 has a stable supporting point.

[0036] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
