[0002] Unmanned aerial vehicles (UAVs) are unmanned vertical takeoff and landing (VTOL) aircraft that are remotely controlled by ground radio and / or autonomously controlled. Structurally, they belong to the category of rotorcraft, and functionally, they are VTOL aircraft. Tandem UAVs possess unique flight performance and application value. They utilize aviation piston diesel engines and a tandem twin-rotor structure, making them suitable for heavy transport and delivery, emergency response, and other missions in complex environments such as mountainous forests and oceans. They also help reduce secondary disasters. Therefore, the radiator is a crucial component of UAVs. Currently, there are no radiator systems specifically designed for tandem UAVs; conventional automotive radiators are still used. However, automotive radiators are connected to the vehicle frame via a base mount, which, due to its unilateral connection and fixation, is unsuitable for use in tandem UAVs.

[0003] This utility model, through its technical feature of integrally fixing the tandem unmanned helicopter with its double-end annular surface and middle bottom surface, effectively explores and studies the technical problem of using ordinary car radiators and connecting them to the car frame through bottom supports.

[0069] In this embodiment, the radiator device body is configured to further include a first main pipe connector 6 and a second main pipe connector 7.

[0070] In this embodiment, a first accessory device is also included and disposed on the radiator device body. The first accessory device is configured to include a first secondary pipe connector 8, a second secondary pipe connector 9, and a plug 91.

[0071] The second embodiment of this utility model is based on the first embodiment.

[0072] This utility model has the following features:

[0073] 1. Due to the design of the radiator device body, connecting component 4 and connecting plate 5, the heat exchange parts of the tandem unmanned helicopter are cooled through the radiator device body. The connecting component 4 enables all-round fixed connection of the left water chamber 1 and the right water chamber 2. The connecting plate 5 enables bottom support and fixation of the radiator core 3. It achieves a double-end annular surface and middle bottom surface overall fixed connection with the tandem unmanned helicopter, which solves the technical problem of using ordinary car radiators and connecting them to the car frame through bottom support.

[0074] 2. By designing the left water chamber 1, the right water chamber 2, the radiator core 3, the first main pipe connector 6, and the second main pipe connector 7, a plate-type radiator is realized.

[0075] 3. Due to the design of the first auxiliary pipe joint 8, the second auxiliary pipe joint 9, and the plug 91, the coolant filling port setting is realized.

[0076] 4. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this utility model, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0077] 5. Due to the design of the technical features of this utility model, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this utility model are at least 1.7 times that of existing performance indicators, and it has been evaluated that it has great market value.

[0078] Other technical features, such as the radiator device body, connecting component 4, and connecting plate 5, which are integrally fixedly connected to the tandem unmanned helicopter with double-end annular surfaces and middle bottom surfaces, are also embodiments of this utility model. Furthermore, the technical features of the above embodiments can be combined arbitrarily. In order to meet the requirements of the Patent Law, the Patent Implementation Regulations, and the Examination Guidelines, all possible combinations of the technical features in the above embodiments will no longer be described.

[0079] Therefore, in the field of radiator device technology for tandem unmanned helicopters, any technical content that includes a radiator device body having a left water chamber 1, a right water chamber 2 and a radiator core 3, a connecting component 4 disposed on the left water chamber 1 and the right water chamber 2, and a connecting plate 5 disposed on the radiator core 3 is within the protection scope of this utility model.
