If an air supply system is arranged near the reflector, the structure of the existing heat dissipation device is often simpler, cooling air flow blown out by the air supply system is often guided to the upper part of the reflector along the outer side of the lampshade, so that partial heat of a lamp body inside the reflector is concentrated, and an electric conductor and a power supply part inside the reflector are easily burnt out under the state of high temperature often, so that the light effect is poor, and the service life of a light source is shortened.
Patent document No. CN 202973023 discloses a light source heat dissipation cooling structure for stage lighting, which mainly includes a reflector and an air supply device disposed outside the reflector, an air outlet of the air supply device is located above an open end of the reflector, a wind blocking sheet is disposed at a position of the air outlet, one end of the wind blocking sheet is connected with the air outlet, and the other end extends toward the light source. The guide cooling airflow with the function of the wind-shielding sheet in the radiator is blown to the inside of the reflector, and meanwhile, most of the cooling airflow which is directly blown to the light source bulb body is blocked, so that the luminous efficiency is improved. However, the wind shield is of a straight piece type, the flow guide effect is not good, and the cooling effect of the bottom position of the reflector cannot be ensured due to the local position of the intelligent direct-blowing lamp housing of the cooling air flow; and still be equipped with the connecting plate of windshield above the open end of reflector, this connecting plate can hinder the shining of light, influences the light effect.
Therefore, it is necessary to develop a heat dissipation system with a reasonable air path design and capable of adapting to different states of the lamp.
Disclosure of Invention
The invention aims to provide a heat dissipation system with a self-adaptive suspension type air path, which has stable air path design and has the function of guiding the flow of cooling air flow to blow from the top to the bottom of a reflector; the lamp rotates to any angle, the wind path and the wind pressure cannot be influenced, and the effect of overall heat dissipation in the reflector is achieved.
In order to achieve the purpose, the invention adopts the following technical scheme:
the heat dissipation system is provided with a suspension air path and is arranged near the opening end of the reflector; the fan comprises a bracket, wherein at least a first turbofan for blowing air and a first cross flow fan for air draft are arranged on the bracket; the first turbofan is provided with a first air outlet, the first cross flow fan is provided with a first air suction opening, and the first air outlet and the first air suction opening are both positioned near the opening end of the reflector; in particular: the first air outlet is connected with a first arc-shaped air duct; the first arc-shaped air duct comprises a first upper baffle, a first lower baffle, a first side baffle, a first connecting piece and a first arc-shaped air guide piece; the first connecting piece is vertically arranged between the first upper baffle and the first lower baffle; the first arc-shaped air guide component is inserted on the first connecting piece and can vertically float up and down along the first connecting piece; the curvature of the convex upper cambered surface of the first arc-shaped air guide piece is greater than that of the concave lower cambered surface of the first arc-shaped air guide piece; the concave lower cambered surface of the first arc-shaped air guide piece faces the first lower baffle.
The working principle of the heat dissipation system is as follows: the first turbofan sends out external cooling airflow through the first air outlet and the first arc-shaped air channel; because the first arc-shaped air guide piece can float up and down relative to the first connecting piece, cooling air flow is blown out horizontally from the first air outlet, and the first arc-shaped air guide piece is blown up by transverse wind power and floats between the first upper baffle and the first lower baffle. Because the curvature of the upper cambered surface of the arc-shaped air guide piece is larger than that of the lower cambered surface, the flow speed of the air flow of the upper cambered surface is higher than that of the air flow of the lower cambered surface on the whole according to Bernoulli's law, namely the static pressure of the air flow acting on the upper cambered surface of the arc-shaped air guide piece is smaller than that acting on the lower cambered surface on the whole. Due to the existence of the pressure difference between the upper cambered surface and the lower cambered surface, the arc-shaped air guide piece is finally subjected to upward resultant force, namely lift force, so that the arc-shaped air guide piece is always in a suspension state. According to the difference of the wind speed and the pressure of the cooling air flow and the change of the attack angle of the first arc-shaped air guide piece, the floating position of the first arc-shaped air guide piece in the vertical direction is different. When the wind power and the wind speed of the airflow blown out by the first turbofan are high, the upper cambered surface of the first arc-shaped air guide piece is attached to the inner side of the first upper baffle, most of the cooling airflow sent out through the first arc-shaped air channel is blown out from the lower part of the first arc-shaped air guide piece and is intensively blown to the bottom of the reflecting cover; when the wind power and the wind speed of the airflow blown out by the first turbofan are low, the first arc-shaped air guide part floats between the first upper baffle and the first lower baffle, the cooling airflow is blown out from the upper part of the first arc-shaped air guide part and also blown out from the lower part of the first arc-shaped air guide part, and the diffusion range of the cooling airflow is wider.

The heat dissipation system comprises a bracket 2 arranged at the periphery of a reflector 1, a first turbofan 3 and a second turbofan 6 for air supply, a first cross flow fan 4 and a second cross flow fan 7 for air extraction are arranged on the bracket 2. The first turbofan 3 and the second turbofan 6 are oppositely arranged at two sides of the reflector 1; the first cross flow fan 4 and the second cross flow fan 7 are also oppositely disposed at both sides of the reflector 1 and respectively located between the first turbo fan 3 and the second turbo fan 6.
The first turbofan 3 is provided with a first air outlet 31, and the first air outlet 31 is connected with a first arc-shaped air duct 5; the second turbofan 6 is provided with a second air outlet 61, and the second air outlet 61 is connected with a second arc-shaped air duct 8; the openings of the first arc-shaped air duct 5 and the second arc-shaped air duct 8 are both towards the inside of the reflector 1. An upper cover 9 is further arranged above the opening end of the reflecting cover 1, a first vent 91 and a second vent 92 are arranged on the upper cover 9, the first vent 91 is communicated with the first air suction opening 41 through a pipeline, and the second vent 92 is communicated with the second air suction opening 71 through a pipeline. As shown in fig. 3, 5 and 6, the reflector 1 has a first groove 11 and a second groove 12 on the edge of the open end. The first arc-shaped air duct 5 is arranged on the first groove 11, and the second arc-shaped air duct 8 is arranged on the second groove 12. The first and second suction ports 41 and 71 are located at a higher level than the first and second outlet ports 31 and 61.
As shown in fig. 3, the first arc wind tunnel 5 includes a first upper baffle 51, a first lower baffle 52, a first side baffle 53, a first connecting member 54, and a first arc wind guide 55. The first connector 54 is vertically installed between the first upper barrier 51 and the first lower barrier 52; the first arc-shaped air guide member 55 is inserted into the first connecting member 54 and can vertically float up and down along the first connecting member 54. The curvature of the convex upper cambered surface of the first arc-shaped air guide piece 55 is greater than that of the concave lower cambered surface of the first arc-shaped air guide piece, the concave lower cambered surface of the first arc-shaped air guide piece faces the first lower baffle plate 52, and the tail part of the first arc-shaped air guide piece 55 extends into the reflecting shade 1.
As shown in fig. 5, the second arc wind tunnel 8 includes a second upper baffle 81, a second lower baffle 82, a second side baffle 83, a second connecting member 84, and a second arc wind guide 85. The second connecting member 85 is vertically installed between the second upper barrier 81 and the second lower barrier 82; the second arc-shaped air guide member 85 is inserted on the second connecting member 84 and can vertically float up and down along the second connecting member 85. The curvature of the convex upper arc surface of the second arc-shaped air guide 85 is greater than that of the concave lower arc surface, the concave lower arc surface faces the second lower baffle 82, and the tail of the second arc-shaped air guide 85 extends into the reflecting shade 1.
The first arc-shaped air guide member 55 and the second arc-shaped air guide member 85 have the same shape, and the first arc-shaped air guide member 55 will be described in detail as an example. As shown in fig. 7, the first curved wind deflector 55 is airfoil-shaped and includes a thicker first curved front end 551 and a thinner first curved rear end 552. The first arc-shaped front end 551 is close to the first air outlet 31, and the first arc-shaped rear end 552 extends above the open end of the reflector 1 and is bent toward the bottom of the reflector 1.

The principle of the heat dissipation system with the suspension air path in the embodiment is as follows: since the curvature of the upper arc surface of the first arc air guide 55 and the second arc air guide 85 is greater than the curvature of the lower arc surface, when the first turbofan 3 and the second turbofan 6 blow the horizontal cooling airflow, the first arc air guide 55 and the second arc air guide 85 finally receive an upward resultant force, that is, a lift force, due to the existence of the pressure difference between the upper arc surface and the lower arc surface, and thus the first arc air guide 55 and the second arc air guide 85 are always in a suspended state. The first turbofan 3 and the second turbofan 6 are independently operated, i.e. the wind power and the wind speed generated by the two may be different. Therefore, the levitation heights of the first arc-shaped wind guide 55 and the second arc-shaped wind guide 85 may be different. The first arc-shaped air duct 5 and the second arc-shaped air duct 8 both have the effect of guiding the cooling air flow to blow towards the bottom of the reflector 1. When the first arc-shaped air guide 55 and the second arc-shaped air guide 85 have different suspension heights, such as the wind force blown by the first turbofan 5 is large, the first arc-shaped air guide 55 can be completely attached to the inner side of the first upper baffle 51, and the cooling air flow blown out by the first arc-shaped air duct 5 is basically concentrated towards the bottom of the reflector 1; the wind force blown by the second turbofan 6 is small, the second arc-shaped air guide 85 is in a state of being suspended between the second upper baffle 81 and the second lower baffle 82, the cooling air flow blown by the second arc-shaped air duct 8 can be blown out from the upper side of the second arc-shaped air guide 85 and can also be blown out from the lower side of the second arc-shaped air guide 85, the cooling air flow tends to diffuse towards the middle part and the horizontal direction in the reflecting cover 1, and the cooling range is wider. Therefore, the purposes of omnibearing heat exchange inside the reflector 1 and better heat dissipation effect of the part with concentrated bottom heat inside the reflector 1 are achieved; and the guide of the arc-shaped air duct can avoid the change of the wind pressure and the wind direction caused by the rotation of the stage lamp.
