Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a heat flow radiator structure. Background Technology

[0002] A radiator is a device used to dissipate heat and is widely used in electronic equipment, automobiles, industrial machinery and other fields to prevent equipment from overheating and maintain its normal operation.

[0003] The conventional radiators of existing diesel vehicles are mostly vertically installed behind the air intake grille at the front of the car. They use vertical fins to conduct heat and dissipate the coolant of the diesel engine. However, with this radiator structure, as the driving time of the diesel vehicle increases, the temperature of the coolant continues to rise. The lack of heat flow guidance for the coolant reduces the heat dissipation efficiency and affects the efficient cooling of the engine.

[0004] Therefore, it is necessary to provide a new heat flow-oriented radiator structure to solve the above-mentioned technical problems. Utility Model Content

[0013] Compared with related technologies, the heat flow-oriented radiator structure provided by this utility model has the following beneficial effects:

[0014] 1. This utility model provides a heat flow guiding radiator structure.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a heat flow-oriented radiator structure, which includes:

[0024] A concave shell 1 has an inlet pipe 2 fixedly installed in the middle of its concave side. Four sets of partition plates 3 are installed on the outer side wall of the inlet pipe 2, dividing the concave shell 1 into four independent cooling chambers 101. The inlet pipe 2 has an inlet hole 201 at one end facing the concave shell 1, which connects the four cooling chambers 101. A sealing plate 4 is installed on the back side of the concave shell 1. Several metal plates 5 are evenly installed on one end of the sealing plate 4 facing the cooling chambers 101. The metal plates 5 are distributed in a stepped manner from the center of the sealing plate 4 to the periphery, and the four independent cooling chambers 101 are evenly separated. Each of the metal plates 5 has a guide hole 501. A return pipe 6 is installed on the four edges of the other end of the sealing plate 4. One end of the return pipe 6 is connected to the corresponding cooling chamber 101, and the other end of the return pipe 6 is fixedly connected to a return tank 7. Several heat dissipation fins 11 are evenly embedded on the front side of the concave shell 1.

[0025] It should be noted that during use, the inlet pipe 2 is connected to the hot liquid of the coolant circulation system of the diesel vehicle, and the return pipe 6 is connected back to the coolant circulation system. This allows the hot coolant after heat exchange to be introduced from the inlet hole 201 into the corresponding cooling chamber 101. Then, under the guidance of the guide holes 501 opened in the stepped metal plate 5, the coolant flows outward from the middle of the concave shell 1. During the flow, the heat dissipation fins 11 on the front side of the concave shell 1 are used for heat conduction and dissipation.

[0026] It is worth noting that: after the front air intake grille of the diesel vehicle is installed on the concave housing 1, when the car is moving, the airflow impacts the concave housing 1 and spreads from the center to the surroundings. This utilizes the natural wind airflow to impact the heat dissipation fins 11 for cooling. This reduces wind resistance and improves the ventilation of the heat dissipation fins 11, thereby improving heat dissipation.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 4 The heat dissipation fins 11 are streamlined in shape, with smaller front and larger back, and are distributed in a denser middle and sparser around the perimeter along the front slope of the concave shell 1.

[0028] It should be noted that this reduces wind resistance while allowing the heat dissipation fins 11 to dissipate heat along the direction of coolant flow.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 4 The other end of the sealing plate 4 has a number of heat dissipation fins 41 evenly distributed, and a cooling fan 42 is symmetrically embedded on the number of heat dissipation fins 41.

[0030] It should be noted that when the diesel vehicle starts, the cooling fan 42 starts simultaneously, and the cooling fins 41 further dissipate heat from the sealing plate 4, thereby improving heat dissipation.

[0031] In this embodiment, a mounting frame 43 is fixedly installed on the sealing plate 4. The mounting frame 43 has a mounting groove and a mounting threaded hole, which facilitates the installation of the entire radiator at the front of the diesel vehicle using the mounting frame 43.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 4 The outer wall of the return tank 7 is uniformly fitted with several heat dissipation fins 71, and the return tank 7 is connected to an oil outlet pipe 72.

[0033] It should be noted that after the coolant is cooled by passing through the cooling chamber 101, it returns to the return tank 7. The return tank 7 further dissipates heat using the heat dissipation fins 71, and then the coolant is guided back to the coolant circulation system through the oil outlet pipe 72 to complete the heat dissipation.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 4 The sealing plate 4 is detachably connected to the concave housing 1 by screws, and a rubber sealing ring 8 is attached to the sealing plate 4;

[0035] The rubber sealing ring 8 has a threaded through hole.

[0036] It should be noted that the sealing plate 4 and the concave housing 1 are installed and sealed by setting a rubber sealing ring 8 to prevent coolant leakage.

[0037] The working principle of the heat flow guiding radiator structure provided by this utility model is as follows:

[0038] In use, the inlet pipe 2 is connected to the hot liquid of the diesel vehicle's coolant circulation system, and the outlet pipe 72 of the return tank 7 is connected back to the coolant circulation system. Then, the hot coolant after heat exchange is introduced into the corresponding cooling chamber 101 through the inlet hole 201. Under the guidance of the guide holes 501 opened in the stepped metal plate 5, it flows outward from the center of the concave shell 1. During the flow, the heat dissipation fins 11 on the front side of the concave shell 1 are used for heat conduction and heat dissipation (the heat dissipation fins 11 dissipate heat by installing the concave shell 1 on the front air intake grille of the diesel vehicle. When the car is moving, when the airflow impacts the concave shell 1, the airflow spreads from the center to the surroundings, thereby using the natural airflow to impact the heat dissipation fins 11 for blowing and heat dissipation. This reduces wind resistance and improves the ventilation of the heat dissipation fins 11, thereby improving heat dissipation). The cooled coolant is introduced into the return tank 7 through the return pipe 6. At the same time, the cooling fan 42 is turned on to further dissipate heat from the sealing plate 4 using the second heat dissipation fin 41, thereby improving heat dissipation.

[0039] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
