Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a heat dissipation device with a turbulence effect. Background Technology

[0002] The radiator is a crucial component of the engine cooling system. Its function is to remove heat from the coolant flowing through the engine, allowing the cooled medium to flow back to the engine for repeated cooling. As engines are upgraded, the requirements for radiator size and heat dissipation capacity are increasing. In some harsh and complex environments, even higher requirements are placed, such as in paper mills, wood processing plants, and agricultural harvesting grounds. These environments often have a lot of fibrous material, which is easily sucked into the radiator core by the vehicle's cooling system fan. If a conventional radiator has a window in the middle, this fibrous material can easily get stuck and quickly block the core, causing the machine to overheat.

[0003] The commonly used method is to remove the radiator opening and use light strips; see [link / reference]. Figure 4 and 5 Because the window structure has been eliminated, the cooling air cannot effectively form turbulence when it blows over the core, resulting in a tiered effect of cooling air and greatly reducing heat dissipation efficiency. In addition, the limited space available in the vehicle makes it impossible to effectively increase the product volume to increase heat dissipation. Under heavy workloads, the amount of heat dissipated by the radiator is only slightly reduced, which can easily cause the machine to overheat.

[0004] Therefore, in order to solve the above problems, this utility model proposes a heat dissipation device with turbulence effect that can avoid the hierarchical effect and improve heat dissipation efficiency. Utility Model Content

[0005] To address the problems existing in the use of the aforementioned heat dissipation devices, this invention provides a heat dissipation device with a turbulence effect.

[0006] According to one objective of this utility model, this utility model provides a heat dissipation device with a turbulence effect, including a main plate, heat dissipation water pipes and heat dissipation strips. The heat dissipation water pipes and the heat dissipation strips are arranged alternately on the main plate along the installation direction. The heat dissipation strips are generally wavy, and the heat dissipation strips are provided with wave peaks and troughs arranged sequentially along the installation direction. The heat dissipation strips form a guide section between the wave peaks and the wave troughs. Adjacent guide sections in the installation direction form a cold air channel. The two ends of the cold air channel in the length direction are an air inlet and an air outlet, respectively.

[0007] The flow guide is provided with several interference flow zones arranged sequentially along the line connecting adjacent wave crests and troughs. The interference flow zones are depressions or protrusions extending perpendicular to the flow guide. The interference flow zones are arranged along the length of the cold air channel. The two ends of the interference flow zones along the length of the cold air channel are respectively connected to the air inlet and the air outlet. The cross-sectional dimensions of two consecutive parts of the interference flow zones along the length of the cold air channel are different.

[0008] Preferably, the two continuous portions of the turbulence zone in the length direction have different dimensions in the direction connecting the crest and the trough, as well as in the direction perpendicular to the guide portion.

[0009] Preferably, two adjacent turbulence zones along the line connecting the crest and the trough have different cross-sectional dimensions at the same portion along the length of the cold air channel.

[0010] Preferably, the cross-sectional shape of the air inlet is different from that of the air outlet.

[0011] Preferably, the surface of the turbulence zone is arc-shaped.

[0012] Preferably, the heat dissipation device further includes a water chamber, the main plate and the water chamber are connected by an assembly, and the water chamber is connected to the heat dissipation water pipe.

[0013] Preferably, the heat dissipation pipes are brazed to connect the heat dissipation strip and the main plate, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This heat dissipation device with turbulence effect increases the heat dissipation area by setting turbulence zones on the wavy heat dissipation strip, thereby achieving a greater heat exchange capacity.

[0016] This heat dissipation device with a turbulence effect limits the cross-sectional dimensions of the turbulence zone, causing the cold air entering through the air inlet to travel a certain distance along the length of the cold air channel before its direction of travel is disrupted, thus achieving a turbulence effect. Ultimately, the cooling air temperature passing through the core is basically the same, ensuring that the cooling air in contact with the high-temperature heat dissipation strip is always at the lowest temperature. This maximizes the heat exchange efficiency to meet usage requirements and avoids the stratification effect that occurs when the air is close to the surface on a regular plane. This prevents the cooling air in contact with the heat dissipation strip from being heated and remaining in contact with the heat dissipation strip for an extended period of time, thus hindering the contact of new low-temperature cooling air with the high-temperature heat dissipation strip to remove heat.

[0023] The following description is intended to provide a detailed account of the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a heat dissipation device with a turbulence effect, comprising: a main plate 100, a heat dissipation water pipe 200, a heat dissipation strip 300 and a water chamber. The heat dissipation water pipe 200 and the heat dissipation strip 300 are alternately arranged on the main plate 100 along the installation direction. The heat dissipation strip 300 is a wave-shaped heat dissipation strip 300. The heat dissipation strip 300 is provided with wave crests 300a and wave troughs 300b arranged sequentially along the installation direction. The heat dissipation strip 300 forms a guide portion 301 between the wave crests 300a and the wave troughs 300b. Adjacent guide portions 301 in the installation direction form a cold air channel a. The two ends of the cold air channel a in the length direction are an air inlet a1 and an air outlet a2, respectively.

[0025] The flow guide 301 is provided with several interference flow zones 3011 arranged sequentially along the line connecting adjacent wave crests 300a and wave troughs 300b. The interference flow zone 3011 is a depression or protrusion extending in a direction perpendicular to the flow guide 301. The interference flow zone 3011 is arranged along the length direction of the cold air channel a. The two ends of the interference flow zone 3011 along the length direction are respectively connected to the air inlet a1 and the air outlet a2. The cross-sectional dimensions of the two consecutive parts of the interference flow zone 3011 along the length direction of the cold air channel a are different.

[0026] By setting a turbulence zone 3011 on the wavy heat dissipation strip 300, the heat dissipation area is increased, thereby achieving a greater heat exchange capacity. By limiting the cross-sectional size of the turbulence zone 3011, the cold air entering through the air inlet a1 is disrupted after traveling a certain distance along the length of the cold air channel a, achieving a turbulence effect. Ultimately, the cooling air temperature passing through the core is basically the same, ensuring that the cooling air in contact with the high-temperature heat dissipation strip 300 is always at the lowest temperature, thereby achieving maximum heat exchange efficiency to meet usage requirements. This avoids the air from being close to the surface on a regular plane, resulting in a tiered effect, which would cause the cooling air in contact with the heat dissipation strip 300 for a long time after being heated, hindering the contact of new low-temperature cooling air with the high-temperature heat dissipation strip 300 to remove heat.

[0027] Furthermore, the surface of the turbulence zone 3011 is arc-shaped to ensure rapid airflow and improve heat exchange efficiency.

[0028] To enhance the turbulence effect of the turbulence zone 3011 on the airflow within the cold air channel a, the two continuous portions of the turbulence zone 3011 in the length direction have different dimensions in the direction connecting the peak 300a and the trough 300b, as well as in the direction perpendicular to the guide portion 301.

[0029] Furthermore, the cross-sectional dimensions of two adjacent turbulence zones 3011 along the line connecting the wave crest 300a and the wave trough 300b are different in the same part along the length of the cold air channel a.

[0030] Furthermore, the cross-sectional shape of the air inlet a1 is different from that of the air outlet a2.

[0031] Furthermore, the main plate 100 and the water chamber are connected by an assembly, and the water chamber is connected to the heat dissipation water pipe 200. By connecting the main plate 100 and the water chamber by an assembly, it is convenient to install and maintain the whole device, which is suitable for large-scale production.

[0032] Furthermore, the heat dissipation pipe 200 is brazed to connect the heat dissipation strip 300 and the main plate 100. Using brazing to connect the main plate 100, heat dissipation strip 300, and heat dissipation pipe 200 of the radiator has advantages such as high connection strength, small heat-affected zone, good appearance and sealing, minimal deformation, adaptability to complex structures, high efficiency and economy, good corrosion resistance, and superior heat dissipation performance.

[0033] In summary, this heat dissipation device with turbulence effect increases the heat dissipation area and improves heat dissipation efficiency to meet the needs of use without increasing the product volume in a limited space.

[0034] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
