[0016] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0017] Example 1:

[0018] like Figure 1-3 As shown:

[0019] Chinese utility model patent application number 202323477357.2 discloses a plate-fin radiator for mining cars. This patent uses a fan to blow air onto the fins of the radiator to improve the heat exchange rate. However, the air outlet of the fan in this patent is far from the fin assembly and does not completely cover the air inlet surface of the fins. Therefore, it cannot effectively blow air into the dense fins, resulting in significant air loss and low working efficiency.

[0020] To address the problem of low heat dissipation efficiency of finned airflow in existing technologies, this utility model provides a plate-finned cooler for small wheel loaders, comprising a cooler body 1, several air inlet channels 2, and an air supply device; the cooler body 1 includes several stacked cold channels 11; both ends of the air inlet channels 2 are respectively provided with connected air outlets and air inlets; the several cold channels 11 correspond one-to-one with the several air inlet channels 2; the air outlet of the air inlet channel 2 is sealed and inserted into the air inlet of the corresponding cold channel 11; the air inlet of the air inlet channel 2 is sealed and connected to the air outlet of the air supply device.

[0021] When the finned cooler for a small wheel loader provided by this utility model is in operation, the air supply device blows air into the air inlet channel 2, and then into the air inlet of the cold channel 11. The air flows through the fins in the cold channel 11 for heat exchange, and finally blows out from the air outlet of the cold channel 11. In the prior art, blowing air directly onto the air inlet surface of the multi-layered cold channel 11 will generate large turbulence, resulting in low air intake efficiency and significant air loss in the cold channel 11. This utility model sets up an air inlet channel 2 corresponding to each layer of the cold channel 11, which can directly send the air into the cold channel 11, ensuring that the influence of the airflow velocity is minimized, and the sealed connection can almost eliminate air loss. To ensure the airtightness of the connection between the cold channel 11, the air inlet channel 2, and the air supply device, a clamping structure or sealant can be set at the connection. If long-term use is required, the cold channel 11, the air inlet channel 2, and the air supply device can be welded together for fixation.

[0022] The present invention provides a plate-fin cooler for a small wheel loader, which sets up multiple air inlet channels 2 corresponding to the multi-layer cold channels 11 of the cooler body 1, so that the multi-layer cold channels 11 are directly connected to the air supply device, thereby reducing air loss and effectively improving heat dissipation efficiency.

[0023] To further improve heat dissipation efficiency without significantly reducing the intake air volume, the gas flow rate blown into the cold channel 11 needs to be increased. To increase the gas flow rate, the gas needs to be pressurized. In a preferred embodiment, the air supply device includes a fan 3 and an air supply hood 4; the two sides of the air supply hood 4 correspond to the air inlet channel 2 and the fan 3, respectively; one side of the air supply hood 4 has several vertically arranged air outlets; each air outlet of the air supply hood 4 corresponds one-to-one with one of the air inlet channels 2; the air outlets of the air supply hood 4 are sealed and connected to the air inlets of the air inlet channels 2; the other side of the air supply hood 4 has an air inlet covering the air supply end of the fan 3; the air outlets of the air supply hood 4 are connected to the air inlets of the air supply hood 4; the cross-sectional area of ​​the air supply hood 4 gradually decreases in the air supply direction.

[0024] When the fan 3 is working and supplying air, the air inlet of the air supply shroud 4 is covered to cover the air supply end of the fan 3, which can prevent the supplied air from overflowing to the outside and causing air volume loss. During the air flow inside the air supply shroud 4, the gas pressure can be increased by gradually narrowing the inside of the air supply shroud 4, thereby increasing the gas flow rate and allowing the gas to enter the cold channel 11 through the air inlet channel 2 at a faster speed, thereby improving the heat exchange efficiency and achieving the effect of improving heat dissipation efficiency.

[0025] The present invention provides a plate-fin cooler for a small wheel loader, which gradually increases the internal gas pressure by setting the cross-sectional area of ​​the air shroud 4 to a gradually decreasing structure, thereby increasing the gas flow rate and improving the heat dissipation efficiency.

[0026] Because the inlet of the cold channel 11 of the plate-fin cooler is generally wide and has 5 sets of wavy fins inside, if the pressurized and accelerated gas is directly sent into the cold channel 11 through the air inlet channel 2, turbulence is very likely to occur, resulting in irregular gas flow and thus reducing the flow rate. To increase the stability of the gas entering the cold channel 11, in a preferred embodiment, the air inlet channel 2 includes several horizontally arranged insertion channels 22; each of the insertion channels 22 has an air outlet and an air inlet connected to each other; the cold channel 11 includes fins 5, end caps 6 on both sides of the fins 5, and partitions 7 on the upper and lower sides of the fins 5; the end caps 6 on both sides of the fins 5 and the partitions 7 on the upper and lower sides of the fins 5 extend towards the air inlet channel 2 by a set distance and together form the air inlet of the cold channel 11; the air inlet of the cold channel 11 is provided with several baffles 21 inside; the baffles 21 are arranged vertically, and the upper and lower sides of the baffles 21 are connected to the air inlet of the cold channel 11; the several baffles 21 divide the air inlet of the cold channel 11 into several insertion interfaces; the several insertion interfaces correspond one-to-one with the several insertion channels 22; the air outlet of the insertion channel 22 is sealed and inserted into the insertion interface; the air inlet of the insertion channel 22 is sealed and connected to the air outlet of the air supply device.

[0027] The present invention provides a plate-fin cooler for a small wheel loader, which divides the air inlet channel 2 into multiple independent plug-in channels 22 to divert the blown gas, thereby preventing the gas from convection and causing a decrease in flow velocity after entering the cold channel 11. At the same time, the baffle 21 can play a guiding role, further improving the stability of the gas.

[0028] To further increase the gas flow rate entering the cold aisle 11, in a preferred embodiment, a turbulence protrusion 24 is provided at the bottom of the inner wall of the insertion channel 22; the turbulence protrusion 24 is arched in the air supply direction; and a guide groove 25 is formed on the arched surface of the turbulence protrusion 24 along the air supply direction. The turbulence protrusion 24 can reduce the internal cross-section of the insertion channel 22, compressing the gas as it passes through, thereby increasing the flow rate. In addition, the turbulence protrusion 24 can change the distribution of the gas flow field, making the gas distribution more uniform within the insertion channel 22, avoiding airflow deflection and fluctuation, thereby increasing the stability of the gas flow. The guide groove 25 can guide the gas flow, further improving the stability of the gas flow.

[0029] The present invention provides a plate-fin cooler for a small wheel loader. By setting an arched turbulence protrusion 24, the flowing gas can be compressed, thereby increasing the flow velocity. It also makes the gas more evenly distributed in the insertion channel 22, increasing the stability of the gas flow.
