Description

Technical Field

[0001] The utility model relates to a cooler and belongs to the technical field of cooling devices. Background Art

[0002] The design of oil cooler is based on the principle of heat exchange. Its main function is to remove heat from oil through heat transfer to maintain the normal operating temperature range of oil. In applications such as internal combustion engines, hydraulic systems and transmissions, the presence of oil cooler is essential, which can effectively improve the efficiency and performance of the system.

[0003] However, for the consideration of exhaust, water and oil drainage, the exhaust port and oil inlet and outlet of the existing cooler are arranged on one side of the fin structure, and the drain port and oil drain port are arranged on one side of the fin structure, so that when the oil inlet and outlet are installed upward, the exhaust port faces upward, and the drain port and oil drain port face downward, which is convenient for removing residual gas, cooling water and oil in the cooling pipeline. However, this arrangement means that the cooler can only be installed with the oil inlet and outlet facing upward. When it is installed sideways, due to the influence of the internal cooling water pipe, the residual oil cannot be completely discharged. Utility Model Content

[0024] Please refer to Figures 1 to 3A cooler shown in an embodiment of the present application comprises a tube body 10, a fin structure 30 arranged in the tube body 10, and end caps 20 arranged at both ends of the tube body 10. A first cooling pipeline and a second cooling pipeline are formed in the fin structure 30. An oil inlet 11 and an oil outlet 12 are respectively arranged at both ends of the tube body 10 in the radial direction, which are connected to both ends of the first cooling pipeline. The projections of the oil inlet 11 and the oil outlet 12 in the axial direction of the tube body 10 overlap. The width direction of the fin structure 30 is extended in an acute angle with the axial direction of the oil inlet 11. Three oil outlets 13 connected to the first cooling pipeline are symmetrically arranged in the radial direction on the tube body 10. The three oil outlets 13 and the oil inlet 11 are arranged at equal intervals along the circumference of the tube body 10. Among them, the first cooling pipeline is used to transport oil, and the second cooling pipeline is used to transport cooling water. The first cooling pipeline and the second cooling pipeline are alternately formed in the fin structure 30, and the oil is cooled by cooling water. The fin structure 30 is a prior art and will not be described in detail here.

[0025] A water inlet 22 and a water outlet 21 connected to the two ends of the second cooling pipeline are arranged on the end cover 20 along the axial direction of the tube body 10, and four drain and exhaust ports 23 connected to the second cooling pipeline are arranged on the end cover 20 along the radial direction of the tube body 10. The four drain and exhaust ports 23 are evenly spaced along the circumference of the end cover 20, and the axial directions of two of the drain and exhaust ports 23 are collinear with the axial direction of the oil inlet 11.

[0026] It should be noted that the drainage and exhaust ports 23 are dual-purpose outlets. Due to the different densities of the gas and cooling water, when the fin structure 30 is in an inclined state, the gas will move upward and the cooling water will move downward, that is, the gas is concentrated at the higher end of the fin structure 30, while the cooling water is concentrated at the lower end of the fin structure 30. Therefore, the drainage port has different functions depending on its orientation. The drainage port acts as an exhaust port for removing gas, and the drainage port facing downward serves as a drainage port for removing cooling water.

[0027] Please refer to Figure 3 In this embodiment, the width direction of the fin structure 30 is arranged to extend in a direction with an angle of 45° with the axial direction of the oil inlet 11. In this way, the angle between the fin structure 30 and each oil discharge port 13 and each water discharge and exhaust port 23 is 45°, so that when the oil inlet 11 of the cooler is installed upward, leftward or rightward, each downward oil discharge port 13, upward exhaust port and downward drain port can have similar oil discharge, exhaust and water discharge effects, ensuring the applicability of the cooler.

[0028] In this embodiment, the water inlet 22 and the water outlet 21 are arranged on the end cover 20 at intervals along the axial direction of the tube body 10, and the water outlet 21 is arranged on the side close to the oil outlet 12. In the actual installation process, the position of the oil inlet 11 is limited, so the water inlet 22 and the water outlet 21 are arranged along the axial direction of the tube body 10 for easy installation.

[0029] In this embodiment, a switch valve is provided on the oil drain port 13 and the water and air outlet 23. The switch valve controls the oil drain port 13 and the water and air outlet 23 to be opened or closed, so as to control the corresponding oil drain port 13 and the water and air outlet 23 to discharge oil, water and air according to the actual installation state.

[0030] In this embodiment, connecting flanges are provided at both ends of the tube body 10, and corresponding connecting parts are provided on the end cover 20. The end cover 20 and the connecting flanges are connected by bolts to facilitate disassembly and installation.

[0031] In this embodiment, a sealing structure is provided between the end cover 20 and the connecting flange, which can enhance the sealing effect between the end cover 20 and the connecting flange and prevent external factors from interfering with the cooling effect in the tube body 10 .

[0032] In this embodiment, the sealing structure is an O-shaped sealing ring. Of course, the sealing structure can also be other forms of sealing rings, such as a U-shaped sealing ring, a V-shaped sealing ring, etc.

[0033] The beneficial effect of the utility model is that the present application arranges the fin structure and the oil inlet at an acute angle, and simultaneously arranges three oil drain ports connected to the first cooling pipeline, so that the oil drain ports and the oil inlet are arranged at equal intervals along the circumference of the tube body, and four drain and exhaust ports are arranged on the end cover corresponding to the setting direction of the oil drain ports and the oil inlet, so that the cooler can be installed upward and laterally along the oil inlet, and the oil drain ports connected below the fin structure can be downward for draining residual oil, and the drain and exhaust ports above the fin structure can be upward for exhaust, and the drain and exhaust ports below the fin structure can be downward for draining cooling water, which increases the installation method of the cooler while ensuring the drainage, exhaust and oil drainage effects, and has a wider applicability.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
