[0004] A 2cm gap is left between the heat sink and the sides on both sides where oil inlet and outlet pipes are provided.

[0005] The bottom of the heat sink is evenly provided with multiple oil grooves.

[0006] The two rows of heat pipes on both sides of the cold water tank extend out of the heat sink and reach the level of the tank opening. The two rows of heat pipes on both sides are vertically equipped with partitions on the opposite sides. The two ends of the partitions are respectively flush with the heat sinks on both sides. An ice block groove is formed between the two partitions and the side walls of the cold water tank, and ice blocks are placed in the ice block groove.

[0008] The beneficial effects of this utility model are as follows: This device uses heat pipes as the heat transfer element, and the heat transfer efficiency of heat pipes is higher than that of direct metal contact heat exchange. At the same time, this device uses a cold water tank filled with ice blocks, and then pours in ice water to submerge the ice blocks. This design reduces the trouble of connecting the inlet and outlet water pipes of the cold water tank for water changes or connecting the fan to electricity, and also allows the oil in the heat dissipation tank to be cooled quickly even in summer when the outside temperature is high. This device only needs to be connected to the aircraft and aviation hydraulic oil pump truck, without the need for other power or water supply connections, making it easy to operate.

[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments: See Figure 1-3 .

[0012] Heat pipes are a common existing technology, and their internal structure will not be described in detail in this case.

[0013] This utility model discloses a heat dissipation component for an aircraft hydraulic oil pump truck, including a heat dissipation tank 1, heat dissipation fins 2, and heat dissipation pipes 3. The main body of the heat dissipation tank is a rectangular parallelepiped structure, and the heat dissipation tank is a six-sided completely enclosed structure. An oil inlet pipe 4 is provided on one side of the upper part of the heat dissipation tank, and an oil outlet pipe 5 is provided on the lower part of the other side of the heat dissipation tank. A cold water tank 6, integrally formed with the heat dissipation tank, is provided above the heat dissipation tank. A completely penetrating opening is provided above the cold water tank, and a matching end cap 7 is provided at the opening. Multiple rows of heat dissipation fins 2 are evenly and vertically arranged inside the heat dissipation tank. The heat dissipation fins and the lines connecting the oil inlet pipe and the oil outlet pipe are parallel, and the upper part of the heat dissipation fins extends into the cold water tank. Multiple heat dissipation pipes 3 are vertically and evenly embedded in the heat dissipation fins. Cold water is injected into the cold water tank. The oil flowing through the heat dissipation tank absorbs heat through the heat dissipation fins 2 and the heat dissipation pipes 3. The evaporating liquid in the heat dissipation pipes 3 absorbs heat and evaporates in the heat dissipation tank 1, and releases heat and condenses in the cold water tank, so that heat is transferred rapidly.

[0014] A 2cm gap is left between the heat sink and the sides on both sides where oil inlet and outlet pipes are provided.

[0015] The bottom of the heat sink has multiple oil channels 8 evenly distributed. The gaps between the heat sink and its sides, as well as the multiple oil channels, can enhance the connection between the separated areas of the heat sink 2.

[0016] Two rows of heat pipes extend from the heat sink on both sides of the cold water tank, reaching the same level as the tank opening. Vertical partitions 9 are installed on the opposite sides of the two rows of heat pipes, with their ends flush with the heat sinks on both sides. An ice trough 10 is formed between the two partitions and the side walls of the cold water tank, and ice is placed in the ice trough. The ice keeps the water temperature very low, and the multiple heat pipes on both sides, as well as the heat sinks 2 directly contacting the ice below the ice trough 10, maximize contact with the ice water, thereby greatly accelerating heat exchange.

[0017] A cooling component for an aircraft hydraulic oil pump truck, characterized in that: a drain outlet 11 is provided on one side of the bottom of the cold water tank, and a matching cover 12 is provided for the drain outlet.

[0018] Specific assembly operations First, place matching ice blocks in the ice tank 10 of this device, and then fill the cold water tank 6 with cold water. The oil inlet pipe 4 and oil outlet pipe 5 on both sides are connected to the aviation hydraulic oil pump truck and the aircraft, respectively. First, the oil is introduced into the heat dissipation tank 1 through the aviation hydraulic oil pump truck. After the heat dissipation tank 1 is full of oil, the valve of the aircraft receiving pipe is opened. While the oil is being rapidly supplied, the heat dissipation tank 1 is always filled with low-temperature oil and the rapidly entering higher-temperature oil, which mixes and cools the tank quickly.

[0019] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
