Description

Outdoor projection equipment

Technical Field

The patent relates to the field of projection equipment, in particular to outdoor projection equipment.

Background

The heat abstractor structure of present outdoor projector equipment is complicated, bulky or the radiating efficiency is low, to outdoor projection equipment, the volume is too big portable and installation of being not convenient for, and the radiating effect is poor to lead to equipment life to shorten greatly. The utility model discloses an application number is 201921844709.4 china utility model discloses an outdoor projector with circulation heat radiation structure has been described, this kind of outdoor projector includes the projecting apparatus body, a housing, the slope recess, the slope bulge, the thermovent, heat dissipation side pipe, copper pipe and heat dissipation panel assembly, the projecting apparatus body is installed in the inner chamber of casing, and the upper cover plate cooperation through the projecting apparatus body goes up four group's screws and the fixed of casing, secondly the slope recess of seting up in the notch bottom of casing is used for cooperating the slope bulge to use, this internal temperature of projecting apparatus enters into the notch of slope recess through the thermovent of seting up on the slope bulge, and through heat dissipation side pipe transmission to steering tube and copper pipe department, and the heat dissipation panel assembly that copper pipe is connected is used for giving off the temperature, realize through the heat dissipation orifice plate.

This technique has the following disadvantages: the heat radiation structure is complicated, the sealing performance of the shell is reduced by the inclined grooves, the position connection of heat radiation components is not compact, the heat radiation performance is poor, and the shell space is occupied.

Disclosure of Invention

In order to solve the deficiency of the prior art, the patent adopts the technical scheme that: the utility model provides an outdoor projection equipment, has included fin, ray apparatus module, and ray apparatus module is on projection equipment's inner frame, and the vertical row of fin is in the side of ray apparatus module bottom. The radiating fins are closely connected with the main heating component optical-mechanical module, so that the contact area of the radiating fins and the optical-mechanical module is increased, and the radiating efficiency is improved.

Detailed description of the preferred embodiments

See fig. 1, 2, 3. The utility model provides an outdoor projection equipment, has included fin 1, ray apparatus module 2 is in on projection equipment's the inner frame 3, the vertical emission of fin 1 is in the side 4 of ray apparatus module 2 bottom.

The heat sink 1 is provided with a plurality of heat dissipation holes 5. The radiating fin 1 is a copper block.

The ray apparatus module 2 bottom has 3 sides 4, fin 1 is 3.

The cooling fin 1 is cuboid and is closely connected with 3 side faces of the bottom of the optical machine module 2 in the vertical direction.

See fig. 1, 4, 5, 6. The outdoor projection equipment further comprises a shell 6, wherein a heat dissipation opening 7 is formed in the bottom of the shell 6, and the heat dissipation opening 7 is close to the heat dissipation fin 1.

The heat dissipation device also comprises a fan 8, and the fan 8 is arranged at the position corresponding to the heat dissipation port 7 on the shell 6.

The radiator structure further comprises a radiator 9, two radiators 9 are arranged on the inner frame 3, the two radiators 9 are arranged adjacently, one radiator 9 is arranged right below the radiating fin 1, and the other radiator 9 is arranged right below the main board 11.

The radiator 9 is composed of a plurality of aluminum sheets 10 in an arrangement.

See fig. 1. Still include mainboard 11, DLP board 12, mainboard 11 with DLP board 12 sets up on the support frame 13 on the inner frame 3 be provided with radiator 9 under the mainboard 11 be provided with fan 8 on the support frame 13.

This patent cooling system's theory of operation: the heat that ray apparatus module 2 during operation produced is passed to three fin 1 that adopt the copper billet preparation, because copper billet heat transfer rate is fast, can pass to radiator 9 to the heat fast, through with the heat is discharged rapidly to the fan 8 that radiator 9 is relative, wherein fan 8 under ray apparatus module 2 inhales the outer cold air of casing through thermovent 7 on the shell 6, and the fan 8 under mainboard 11 passes through thermovent 7 on the shell 6 with the heat that equipment produced and discharges outward to the casing, and two fans play the effect of convection current and wind path, through such a circulation system, can high-efficiently discharge heat fast. Meanwhile, the radiating fins 1 are provided with a plurality of radiating holes 5, so that the effect of rapid radiating can be achieved. In addition, the heat generated from the main board 11 and the DLP board 12 is also discharged through the above circulation system.
