Referring to fig. 1 to 6, the high-efficiency heat dissipation module lamp provided in this embodiment mainly includes a main body device 10, a light emitting device 20, and a heat dissipation device 30.

Specifically, the heat dissipation back plate 24 is connected to the second step 14 of the lamp housing 11, through holes for screws to pass through are further formed in the heat dissipation back plate 24 and the light source assembly plate 23, when the heat dissipation back plate is fixed, the heat dissipation back plate 24 is firstly placed on the second step 14, in order to ensure waterproof sealing performance, a sealing gasket or an O-shaped sealing ring is usually placed between the joint of the heat dissipation back plate 24 and the second step 14, the light source assembly plate 23 is then placed on the heat dissipation back plate 24 and is screwed and fixed on the second step 14 of the lamp housing 11 by screws, and at this time, one surface of the light source assembly plate 23 is tightly attached to one surface of the heat dissipation back plate 24. Preferably, a heat-conducting glue with good heat-conducting property is smeared on the contact surface of the light source group plate 23 and the heat dissipation back plate 24, so as to ensure close contact, no gap and uniform heat transfer between the contact surfaces of the light source group plate 23 and the heat dissipation back plate 24.
In this embodiment, the heat dissipating device 30 includes a rear cover 32, the rear cover 32 is hermetically fixed at the end of the lamp housing 11 and forms a cavity with the heat dissipating back plate 24, in order to ensure the sealing performance, a sealing gasket or an O-ring is usually disposed between the rear cover 32 and the contact surface of the lamp housing 11, a fluid inlet 15 and a fluid outlet 16 are disposed on the cavity, the cavity is further provided with a fluid channel communicating the fluid inlet 15 and the fluid outlet 16, the fluid channel is a channel capable of enabling a fluid to freely and smoothly flow, one end of the fluid channel is communicated with the fluid inlet 15, the other end of the fluid channel is communicated with the fluid outlet 16, the fluid channel is disposed to enable the fluid to flow more uniformly and smoothly, and the fluid channel covers the surface of the heat dissipating back plate 24 exposed to the cavity and can guide the fluid. When the lamp works, fluid for heat dissipation can enter the cavity from the fluid inlet 15, flow through the fluid channel, and then flow out of the cavity from the fluid outlet 16, and the fluid channel can make the flowing fluid fully contact with the heat dissipation back plate 24. In practical operation, a large amount of heat is generated during the operation of the light emitting sources on the light source group plate 23, most of the heat is concentrated on the light source group plate 23, because the light source group plate 23 and the heat dissipation back plate 24 are tightly attached together, the heat is further diffused to the heat dissipation back plate 24, meanwhile, the fluid with the heat dissipation function flows in from the fluid inlet 15 and fills the fluid channel in the cavity, the fluid is fully contacted with the heat dissipation back plate 24 through the fluid channel, because the temperature of the fluid is lower than that of the heat dissipation back plate 24, the heat is spontaneously conducted from the heat dissipation back plate 24 to the flowing fluid, and the flowing fluid continuously takes away the heat from the heat dissipation back plate 24 of the cavity and flows out from the fluid outlet 16, so that the temperature of the light emitting sources on the light source group plate 23 is kept in a stable range. The design fully takes away heat in the lamp, fluid flowing in the fluid channel enables heat dissipation to be more sufficient, the lamp is in a normal working state for a long time, and the service life of the lamp is prolonged.
Further, a fluid rectifier 31 is arranged in the fluid channel, the fluid rectifier 31 is provided with a rectifying input end and a rectifying output end, the rectifying input end faces the fluid inlet 15, a gap is arranged between the rectifying input end and the fluid inlet 15, the rectifying output end faces the fluid outlet 16, and the rectifying input end and the rectifying output end are both provided with a plurality of rectifying holes which are arranged in an array. Wherein the rectifying hole is used for adjusting the fluid flow of the cross section perpendicular to the fluid flow direction in the fluid channel. Specifically, the flow rate of the fluid in the cross section perpendicular to the fluid flowing direction in the fluid channel can be adjusted by adjusting the number and size of the rectifying holes arranged at the rectifying input end and the rectifying output end, so that the fluid is uniformly distributed, the fluid resistance of the fluid in the fluid channel is basically consistent, and the heat on the heat dissipation back plate 24 can be uniformly carried away. At the start of operation, the fluid is preferably introduced at a high flow rate to fill the fluid channels as much as possible so that the fluid is in sufficient contact with the heat sink back plate 24. The rectifying holes of the rectifying input and the rectifying output enable the fluid to uniformly pass through various cross sections in the flow direction. Therefore, the fluid can uniformly flow into the fluid channel from the rectifying holes of the rectifying input end, the fluid filling the whole fluid channel is fully and uniformly contacted with the heat dissipation back plate 24, and the heat on the heat dissipation back plate 24 is absorbed. In general, the fluid rectifier 31 with the rectifying holes plays a role in speed and current regulation, so that the fluid on the fluid channel in the cavity can sufficiently absorb the heat of the heat dissipation back plate 24, and the heat dissipation efficiency of the lamp is further improved.
Further, referring to fig. 6 and 8, a plurality of fins are disposed on a side of the heat dissipation back plate 24 facing the back cover 32, the fins are arranged in a comb shape, the fins are inserted into the fluid rectifier 31 and located in the fluid channel, a fluid flow channel for flowing the fluid is disposed between adjacent fins, the direction of the fluid flow channel for flowing the fluid can refer to the direction of the arrow shown in fig. 8, specifically, the fluid enters from the fluid inlet 15, is uniformly distributed into the fluid flow channel through the flow-adjusting holes on the flow-adjusting input end of the fluid rectifier 31, uniformly flows through the fins in the fluid channel, is collected from the fluid flow channel to the flow-adjusting output end of the fluid rectifier 31, flows out from the flow-adjusting holes on the flow-adjusting output end to the fluid outlet 16, and finally flows out of the. In practical production, the number and height of the radiating fins can be adjusted according to the power of the lamp. The addition of the radiating fins increases the surface area of the radiating back plate 24 exposed on the fluid channel in the cavity, the radiating fins arranged in an array can ensure that fluid uniformly passing through the fluid channel can fully and uniformly contact the radiating fins, the surface area of the radiating back plate 24 contacting with the fluid during working is further increased, the speed of heat conduction from the radiating back plate 24 to the fluid can be accelerated, and the radiating problem of the lamp can be more effectively and fully improved. In this embodiment, the heat dissipation back plate 24 may be made of a material with good thermal conductivity, such as aluminum or copper among metal materials.
In this embodiment, referring to fig. 5 and 6, the fluid inlet 15 and the fluid outlet 16 are disposed on the lamp housing 11, specifically, the centerline of the fluid inlet 15 is collinear with the centerline of the fluid outlet 16 and parallel to the fluid flow path, the fluid rectifier 31 is annular, and the centerline of the rectifying hole is parallel to the fluid flow path, so that the fluid flowing through the fluid channel and the heat sink is smooth, and the fluid flowing from the fluid inlet 15 can be uniformly distributed to the rectifying holes of the annular fluid rectifier 31. As can be seen from fig. 8, the straight distance between the fluid inlet 15 and the fluid outlet 16 is shortest, the flow path of the fluid is also shortest, the fluid resistance of the fluid on the corresponding fluid flow path of the section is smallest, and in order to make the fluid pass more uniformly, in combination with fig. 6, it is required to reduce the diameter and density of the rectifying holes of which the rectifying input end faces the fluid inlet 15 and the rectifying output end faces the fluid outlet 16, and increase the diameter and density of the rectifying holes of which the rectifying input end is not directly opposite and far away from the fluid inlet 15 and the rectifying output end is not directly opposite and far away from the fluid outlet 16, and this design adjustment can adjust the fluid resistance on different fluid paths of the fluid. In the present embodiment, R represents the fluid resistance, the path length of the fluid flow path is represented by L, as shown in fig. 9, a circle can be regarded as the fluid rectifier 31, R represents the radius of the fluid rectifier 31, the flow direction of the fluid flow path represented by an arrow increases with the increase of the angle θ, L is in positive correlation with θ, the specific calculation formula is that L (θ) is 2R (θ + cos θ), the change curve graph shown in fig. 10 is drawn by the data calculated by the calculation formula, and L linearly increases from 1 to 1.4 at 0 to 30 °; increasing L linearly from 1.4 to 1.5 at 30-45 ℃; increasing L linearly from 1.5 to 1.55 at 45-60 ℃; increasing L linearly from 1.55 to 1.57 at 60-75 ℃; and at 75-90 degrees, L is basically maintained at 1.57 without too large fluctuation. Here, the cross-sectional area of the fluid flow path is represented by a, and the calculation formula of the fluid resistance R is R ═ KL/a, where K is a constant, and both the cross-sectional area a and the path length L of the fluid flow path are related to the fluid resistance. Of course, in practice, the positions of the fluid inlet 15 and the fluid outlet 16 are not limited to the lamp housing 11 in this embodiment, but other embodiments are possible, such as the rear cover 32, and the center line of the fluid inlet 15 and the center line of the fluid outlet 16 are not necessarily arranged in a line.

The first isolation boss 33 and the second isolation boss 34 which are symmetrically arranged form a gap between the rectification input end and the fluid inlet 15 with the lamp housing 11, so that fluid can uniformly flow through the rectification holes of the rectification input end when passing through, and the rectification purpose is achieved.
In a specific embodiment, the fluid in the fluid channel is air and/or water, and the fluid can be any fluid having the ability to carry heat, such as water, air, oil, etc. In particular, when the fluid is air, the fluid inlet 15 is circumscribed by a device capable of providing a flow of air, such as an electric fan, blower, or the like.
