Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers for passenger cars, commercial vehicles and engineering machinery, in particular to a guide plate for a radiator water pipe outlet, which is suitable for a radiator of an engine cooling system with high horsepower and high flow rate of coolant. Background Art

[0002] Today, major commercial vehicle brands have significantly increased the horsepower of heavy-duty truck engines to more than 600 horsepower. At the same time, high-horsepower heavy-duty trucks have further improved their heat exchange capacity. In order to meet the heat dissipation requirements, engine manufacturers have increased the head and flow of the engine water pump, which results in a high-speed, high-pressure turbulent area in the radiator water inlet area when the engine is working, causing serious erosion and corrosion to the cooling pipe head and cooling pipe foot welds of the radiator core, reducing the service life of the radiator.

[0003] At present, the common solution is to bulge the water chamber, move the water inlet pipe away from the cooling pipe head, and increase the inlet diameter of the radiator to reduce the flow rate of the pipe as much as possible. However, since the flow state of the coolant has not changed, the scouring problem of high-speed turbulent flow has not been fundamentally solved, and the scouring corrosion has not been eradicated. Utility Model Content

[0004] The utility model aims to provide a guide plate for the water pipe outlet of a radiator, which can guide high-pressure and high-speed coolant to outside the water inlet area, thereby reducing the coolant flow rate in the water inlet area of ​​the radiator, reducing or eliminating the erosion and corrosion of the coolant on the cooling pipe head and the pipe foot weld in the water inlet pipe area, thereby improving the service life of the radiator.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is to provide a radiator water pipe outlet guide plate. The radiator water pipe outlet guide plate is a guide plate with an inclined angle added to the lower half of the inner cavity of the radiator water inlet pipe outlet, and the inclined surface of the guide plate faces the tail of the radiator water chamber away from the water pipe outlet.

[0006] The lower half of the inner cavity of the radiator water inlet pipe opening is below the center line of the cross section of the radiator water inlet pipe.

[0007] The guide plate with an additional inclined angle is connected to the water chamber as a whole by water chamber injection molding, welding or adhesive.

[0008] The guide plate with an inclined angle means that the guide plate is parallel to the axis of the water pipe outlet in the normal direction of the inner cavity of the water inlet pipe, and forms an angle with the length direction of the water chamber in the tangent direction.

[0009] The inclined surface of the guide plate faces the tail of the radiator water chamber away from the water pipe outlet, which refers to the angle between the guide plate and the length of the water chamber. The side with a larger angle faces the side with a larger length of the water chamber; the other side with a smaller angle faces the other side with a shorter length of the water chamber.

[0010] The outstanding effects of the utility model are:

[0011] 1. The use of the radiator water pipe outlet guide plate can effectively disperse and guide the coolant in the radiator to the outside of the water inlet area, reduce or eliminate the high-speed and high-pressure turbulent area formed in the radiator water inlet area due to large flow of coolant, reduce the erosion and corrosion of the coolant on the cooling pipe head and weld in the radiator water inlet area, thereby extending the service life of the radiator.

[0012] 2. The guide plate at the water pipe outlet is connected to the water chamber by injection molding, welding or bonding. The structure is reliable and firm, has no other impact on the radiator, and can meet the operation of mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 The utility model is a schematic diagram of the working principle of the guide plate of the radiator water pipe outlet.

[0014] Figure 2 yes Figure 1 AA section view.

[0015] Marked in the figure: water chamber 1, water inlet pipe 2, guide plate 3. DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

[0017] like Figure 1 to Figure 2 As shown, a radiator water pipe outlet guide plate described in the utility model is a radiator water pipe outlet guide plate, wherein a guide plate 3 with an inclined angle is added to the lower half of the inner cavity of the radiator water inlet pipe outlet 2, and the inclined surface of the guide plate faces the tail of the radiator water chamber away from the water pipe outlet.

[0018] The lower half of the inner cavity of the radiator water inlet pipe port 2 is below the center line of the cross section of the radiator water inlet pipe.

[0019] The guide plate 3 additionally provided with an inclined angle means that the guide plate and the water chamber are connected as one by water chamber injection molding, welding or adhesive.

[0020] The guide plate 3 with an inclined angle means that the normal direction of the inner cavity of the water inlet pipe is parallel to the axis of the water pipe outlet, and the tangent direction forms an angle with the length direction of the water chamber.

[0021] The inclined surface of the guide plate faces the tail of the radiator water chamber away from the water pipe outlet, which refers to the angle between the guide plate and the length of the water chamber. The side with a larger angle faces the side with a larger length of the water chamber; the other side with a smaller angle faces the other side with a shorter length of the water chamber.

[0022] Working principle of the radiator water pipe outlet guide plate described in the utility model:

[0023] As shown in the left figure of Figure 1, the guide plate divides the inner cavity of the water inlet into upper and lower channels, and the flow area of ​​the upper channel is larger than that of the lower channel. When the radiator is working, the coolant in the upper channel flows to the inner cavity of the left water chamber under the action of the guide plate, and the coolant in the lower channel flows directly to the core below the water inlet. The guide plate and the water chamber are connected together by water chamber injection molding, welding or bonding. By adjusting the inclination angle of the guide plate and adjusting the position and size of the guide plate in the cross section of the water pipe mouth, the service life of the radiator can be increased.
