All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As shown in fig. 1 and 2, an embodiment of the present invention discloses a heat dissipation structure, which includes a housing 100. The present invention is mainly applied to a dental electric motor, and the following embodiments will be described by taking the dental electric motor as an example. Of course, the utility model discloses also can be applied to other scenes, technical field such as computer equipment, air conditioner. Any application field provided by the embodiment is within the protection scope of the present application.

Wherein, casing 100 comprises backplate 101, panel, roof, bottom plate and curb plate, and backplate 101, panel, roof, bottom plate and curb plate enclose to establish and form the cavity, and wherein panel, roof, bottom plate and curb plate injection moulding structure as an organic whole, backplate 101 can be dismantled with above-mentioned integrative injection moulding structure and be connected to heating element in convenient installation casing 100. An air inlet and an air outlet 102 are arranged on the outer surface of the casing 100, and air flow enters from the air inlet and is discharged from the air outlet 102, so that the air flow in the casing 100 circulates to the outside of the casing 100, and heat exchange is performed between the air and a heating element in the casing 100, and heat of the heating element is taken away. It should be noted that the outer surface refers to a back surface, a side surface, a top surface or a bottom surface, and in order to ensure that the airflow enters from the air inlet and can flow through all the heating elements when being discharged from the air outlet 102, the air inlet and the air outlet 102 need to be arranged on different surfaces.

The interior of the housing 100 is divided into a plurality of mounting areas for mounting components such as a circuit module, a peristaltic pump driver, and an air pump, respectively. This embodiment is through separating the inside of casing 100 for a plurality of installation areas to the different subassemblies of installation for dental electric motor's inside overall arrangement is more reasonable, more does benefit to the heat that heating element was taken away in the air flow.

The connecting position of two adjacent installation areas can be provided with a communication hole, so that the installation areas are mutually communicated, the installation areas can be sequentially communicated through the communication hole, and of course, the installation areas can be mutually communicated through the communication hole. And the air inlet, the communication holes of each mounting area and the air outlet 102 form a complete heat dissipation path. It should be noted that, the sequential connection means that the air flow enters the housing 100 from the air inlet, sequentially passes through the communication holes of the installation areas, and is discharged from the air outlet 102 to form a heat dissipation path; the mutual communication means that the air flow enters the housing 100 from the air inlet, passes through the communication holes of each installation area, and is discharged from the air outlet 102 to form a plurality of heat dissipation paths.

When air current enters from the air inlet, the air current flows through the communicating holes of each mounting area in sequence, exchanges heat with each internal component and then is discharged from the air outlet 102, so that the heat dissipation of the internal components of the dental electric motor is realized, and the temperature of the internal components is reduced.

Further, since the density of the hot airflow is relatively low, the hot airflow will converge in the upper space, and therefore, the position of the air outlet 102 is higher than that of the air inlet in the direction along the height of the casing 100, so as to ensure that the airflow enters from the air inlet and is discharged from the air outlet 102, and in order to prevent the hot airflow discharged from the air outlet 102 from being sucked by the air inlet, the air outlet 102 and the air inlet need to be disposed on different surfaces of the casing 100.

Further, as shown in fig. 2, in a specific embodiment, there are at least three installation areas, it should be noted that the installation areas may also be four or more than five, and the number of the specific installation areas needs to be determined by those skilled in the art according to a specific application scenario. As will be understood by those skilled in the art, the main heat dissipation components of the dental electric motor are a circuit module, a peristaltic pump driver and an air pump, so that the cavity of the housing 100 is divided into three mounting areas to achieve a good heat dissipation effect.

For convenience of understanding, as shown in fig. 3, three mounting regions are defined as a first mounting region 201, a second mounting region 202 and a third mounting region 203, respectively, and it should be noted that the first mounting region 201 is used for mounting a circuit module, the second mounting region 202 is used for mounting a peristaltic pump driver, and the third mounting region 203 is used for mounting an air pump. Wherein, since the weight of the circuit module is lighter than that of the peristaltic pump and the air pump, the first mounting region 201 is disposed on the top of the second mounting region 202 and the third mounting region 203 to lower the center of gravity of the dental electric motor in consideration of the stability of the dental electric motor.

It should be noted that, because the hot air flow density is low and is easy to converge in the first mounting region 201 at the top, in order to exhaust the hot air flow out of the casing 100 as soon as possible, the air outlet 102 is disposed at a position opposite to the first mounting region 201.

It should be noted that the first end is an end of the air outlet 102 located in the cavity of the housing 100, and the second end is an end of the air outlet 102 located outside the housing 100. The air outlet 102 is inclined from the first end to the second end toward the bottom of the casing 100, so that the hot air flows to the lower part of the casing 100 and is discharged, the hot air flows to the ground, and discomfort caused by the hot air flowing to doctors and patients is avoided. Furthermore, the inclined arrangement of the air outlet 102 can prevent condensed water formed on the back plate 101 or water poured on the back plate 101 from flowing into the cavity of the housing 100 through the air outlet 102, so as to cause damages such as corrosion and short circuit to internal components.

Further, in one embodiment, the air inlets have at least two air inlets, which are defined as the first air inlet portion 103 and the second air inlet portion 104 for convenience of understanding. The first air inlet portion 103 and the second air inlet portion 104 are disposed on two sides of the housing 100, and the first air inlet portion 103 located on one side of the housing 100 is communicated with the second installation area 202, and the second air inlet portion 104 located on the other side of the housing 100 is communicated with the third installation area 203.
