Description

Cooling device for remote control model

The present invention relates to a heat dissipation device, and in particular to a heat dissipation device for a remote control model that can simultaneously dissipate heat from the motor and electronic transmission of the remote control model.

With the advancement of technology, the precision of remote control models is getting closer and closer to real products. For example, the current remote control helicopters can fly continuously in the air and perform different flying skills under the control of the controller through the motor and electronic transmission installed inside. However, the flight time of remote control helicopters is limited by the motor and electronic transmission. The reason is that the motor and electronic transmission will generate heat when they are running continuously, so the remote control helicopter must land to dissipate heat every 5 to 10 minutes of flight on average.

Generally speaking, to cool the motor and electronic transmission of a remote-controlled helicopter, the outer casing must be removed to expose the internal structure, and then a known heat sink is used. A fan is installed on one end of the heat sink, and an opening is provided on the other end. The heat sink is placed above the motor or electronic transmission and the airflow is blown out from the opening by the rotation of the fan. Since the heat sink has only one opening, the heat sink can only cool one of the motor or electronic transmission at the same time. After the heat sink is cooled, the heat sink will move to the other one for cooling. This will require twice the cooling time, which will affect the user's gaming experience. On the other hand, users can also choose to use two known heat sinks for cooling at the same time, but this will increase the user's additional economic cost and carrying cost.

Therefore, how to provide a heat sink that can improve heat dissipation efficiency and solve the problem of economic cost or carrying cost is one of the issues that the industry and researchers in the relevant fields need to solve urgently.

The main purpose of the invention is to provide a heat dissipation device for a remote control model, which can improve the heat dissipation efficiency and solve the problem of carrying cost.

Please refer to FIG. 1, a heat dissipation device of a remote control model provided by a preferred embodiment of the present invention mainly comprises: a body 1, a fan device 2 and a power supply device 3. Wherein: please refer to FIG. 2 and FIG. 3, the body 1 has a first shell 10, a second shell 20 and a connecting shell 30. The first shell 10 is a hollow tube in a generally cylindrical shape, with a first airflow space 11 inside, and a first airflow inlet 12 and a first airflow outlet 13 connected to the first airflow space 11 at both ends. Specifically, one axial end of the first shell 10 is connected to the connecting shell 30, and the first airflow inlet 12 is formed at one end of the first shell 10 connected to the connecting shell 30, so that the first airflow space 11 is connected to the inside of the connecting shell 30. The other axial end of the first shell 10 has the first airflow outlet 13, which is a predetermined distance away from the first airflow inlet 12. Among them, a first airflow direction L1 is defined as the direction from the first airflow inlet 12 to the first airflow outlet 13 (as shown in Figure 4). The first shell 10 has a plurality of guide plates 14. The guide plates 14 surround the inner wall surface of the first shell 10 and extend toward the center of the first shell 10. An airflow channel 140 is formed between any two of the guide plates 14, and the airflow channels 140 are connected to the first airflow outlet 13. In addition, the first housing 10 has a plurality of top plates 15, each of which is connected to one end of each of the guide plates 14 near the first airflow inlet 12. The width of the top plate 15 is greater than the width of the guide plate 14, which means that each of the top plates 15 is closer to the axis of the first housing 10 than each of the guide plates 14.

The second housing 20 is a generally flat hollow tube, one end of which is connected to the outer circumferential wall of the first housing 10, and the other end of which extends obliquely away from the first housing 10, so that the second housing 20 and the first housing 10 form an angle of less than 90 degrees. The second housing 20 has a second airflow space 21 inside, and has a second airflow inlet 22 and a second airflow outlet 23 connected to the second airflow space 21 at both ends. Specifically, the second airflow inlet 22 is provided at one end of the second housing 20 adjacent to the first housing 10, so that the first airflow space 11 of the first housing 10 is connected to the second airflow space 21 of the second housing 20. At least one of the airflow channels 140 of the first housing 10 is connected to the second airflow inlet 22. The second airflow outlet 23 is located at one end of the second housing 20 away from the first housing 10, and is connected to the second airflow space 21 of the second housing 20 and the outside. A second airflow direction L2 is defined as the direction from the second airflow inlet 22 toward the second airflow outlet 23 (as shown in FIG. 4). In this embodiment, the first airflow outlet 13 and the second airflow outlet 23 are not connected to each other, and the first airflow direction L1 and the second airflow direction L2 form an angle that is not equal to 0.

The connecting housing 30 is a square hollow tube, which is arranged above the first housing 10. The connecting housing 30 has a fan accommodating space 31 inside for accommodating the fan device 2. The fan accommodating space 31 is connected to the first airflow space 11 through the first airflow inlet 12 of the first housing 10.

The fan device 2 is detachably locked to the connecting housing 30. The fan device 2 has a plurality of fan blades 2a at one end adjacent to the first airflow inlet 12, which are driven to rotate, thereby generating an airflow that blows along the first airflow inlet 12 into the first airflow space 11 of the first housing 10. The fan device 2 is a known technology, and its details are not described here.

The power supply device 3 is electrically connected to the fan device 2 to provide the power required for the fan device 2 to operate. In this embodiment, the power supply device 3 is an external battery connected to the outer wall of the connection housing 30. In another embodiment, the power supply device can be replaced by an external power source separated from the main body or a built-in battery installed inside the fan device.

In this embodiment, the body 1 further has a switch 40, which is disposed on the connection housing 30 and electrically connected to the fan device 2 and the power supply device 3. The switch 40 can be operated to switch between an on state and a off state. When the switch 40 is switched to the on state, the switch 40 controls the fan device 2 to form an electrically connected state with the power supply device 3, so that the power supply device 3 can supply power to the fan device 2. When the switch 40 is switched to the off state, the switch 40 controls the fan device 2 to form an electrically disconnected state with the power supply device 3, so that the power supply device 3 stops supplying power to the fan device 2.

According to the above structural configuration, the actual operation and application of the heat dissipation device of the remote control model provided by the present invention is as follows: Please refer to FIG. 4. When a remote control model 4 is to be cooled, the user first disassembles the remote control model 4 to expose the two heat dissipation parts of the remote control model 4. In this embodiment, the two heat dissipation parts are a motor 5 and an electronic transmission 6. Then, the user can cover the first shell 10 of the main body 1 on the motor 5, so that the first shell 10 corresponds to the motor 5, and the second shell 20 corresponds to the electronic transmission 6. At this time, since the top end of the motor 5 is against the top-affecting plates 15 and is at a distance from the first air flow inlet 12 of the first housing 10, the air flow generated by the fan device 2 can pass through the first air flow inlet 12 into the first air flow space 11 and blow out toward the first air flow outlet 13 along the first air flow direction L1 to dissipate heat from the motor 5. In addition, due to the structure of the guide pieces 14, a plurality of tiny gaps (i.e., the airflow channels 140) are formed between the motor 5 and the inner wall surface of the first housing 10, whereby the airflow generated by the fan device 2 not only blows toward the motor 5 along the first airflow direction L1 to dissipate heat, but also at least a portion of the airflow can pass through the second airflow inlet 22 of the second housing 20 along the airflow channels 140 to enter the second airflow space 21, and blow out toward the second airflow outlet 23 along the second airflow direction L2 to dissipate heat for the electronic transmission 6, thereby achieving the effect of dissipating heat for the two heat dissipation components at the same time.

In summary, the remote control model heat dissipation device provided by the present invention can make the airflow generated by the fan device 2 blow out along the different first airflow directions L1 and the second airflow directions L2 through the first airflow outlet 13 of the first shell 10 and the second airflow outlet 23 of the second shell 20 in different directions, so as to blow to the two heat dissipation parts at the same time for synchronous heat dissipation. This can effectively improve the overall heat dissipation efficiency and solve the problem of economic cost and carrying cost of preparing multiple heat dissipation devices.

Anyone skilled in the art can modify and change the above embodiments without violating the technical principles and spirit of the present invention.
