Automobile heat radiator with water chamber rectification baffle plate

Abstract

The invention discloses an automobile heat radiator with a water chamber rectification baffle plate, wherein the automobile heat radiator mainly comprises a water inflow water chamber with a cooling liquid inlet, a water outlet water chamber with a cooling liquid outlet, a cooling pipeline and a rectification baffle plate, wherein the cooling pipeline penetrates through and is communicated with the water inflow water chamber and the water outlet water chamber; the cooling liquid inlet and the cooling liquid outlet are arranged at the same side of the heat radiator; the rectification baffle plate is arranged in the water inflow water chamber and is close to one side of the cooling liquid outlet; and an inverted T-shaped opening is formed on the rectification baffle plate. According to the invention, through the arrangement of the rectification baffle plate in the water inflow water chamber, the short-circuit flowing of the cooling liquid is restrained, thus the cooling liquid is compelled to pass through each cooling pipeline uniformly and then enters the water outlet water chamber, and the flowing in each cooling pipeline of the heat radiator is relatively uniform, thus the integral heat radiation performance of the heat radiator is improved, the flow resistance is reduced, and the temperature difference between the left side and the right side is reduced so as to prevent the heat stress from damaging the structure of the heat radiator.

Description

technical field [0001] The invention relates to the technical field of automobile radiators, in particular to an automobile radiator with a water chamber rectifying baffle. Background technique [0002] The main performance index of automobile radiator is its heat dissipation performance and gas side pressure loss. Under certain conditions, the flow resistance of the coolant inside the radiator is also one of its important performance indicators. In addition, the structural fatigue resistance of the radiator, that is, durability is also one of its key performance indicators. [0003] Such as figure 1 Shown is an existing car radiator structure, which mainly includes a water inlet chamber 14, a cooling pipeline 13, an outlet water chamber 15, and a fan 16 and the like. Due to the space limitation of the whole vehicle structure, the coolant inlet 11 and the coolant outlet 12 of the radiator are set on the same side of the radiator ( figure 1 center right).

AI Technical Summary

Problems solved by technology

Since the number of cooling pipelines on the left side of the coolant inlet 11 is more than that on the right side, the flow rate in most of the cooling pipelines of the entire radiator is very small, and the flow rate in a small part is very large. Eliminates the uneven flow of coolant in the cooling pipes in different areas

Considering that the fan 16 is arranged in figure 1 On the left side of the middle coolant inlet 11 (coolant low flow area), this part of the coolant cannot be sufficiently cooled and cannot dissipate heat, which further aggravates the unevenness of the heat dissipation effect on both sides of the radiator, resulting in the overall heat dissipation of the radiator. Decreased cooling performance, unable to meet heat dissipation function requirements

[0005] At the same time, due to the difference in heat dissipation between the left and right sides of the radiator, a large temperature difference is formed on both sides of the radiator. figure 1 The temperature of each cooling pipeline on the left side of the center is significantly lower than figure 1 The temperature of the cooling pipeline on the right side of the center, under the action of thermal expansion and contraction, the radiator has to bear a large thermal stress difference, which has an adverse effect on the structural stability of the radiator, and it is easy to cause the cooling pipeline to open welding Phenomenon, in practice, the leakage of the radiator is more prominent

[0006] In addition, due to the uneven flow of coolant in the cooling pipeline of the radiator, the flow resistance of the coolant is also relatively large, which intensifies the negative effect on the heat dissipation effect.
