Description

Technical Field

[0001] The utility model relates to the technical field of high-power ballasts, and particularly relates to a ballast heat dissipation shell. Background Art

[0002] A high-pressure sodium lamp ballast, as an important accessory for lighting equipment, is mainly applied in environments that require high-intensity lighting. It can help stabilize the current, protect the bulb, ensure the normal operation of the high-pressure sodium lamp, and thus provide stable and efficient lighting effects. At the same time, in order to ensure the stability of the ballast, several heat dissipation fins are generally arranged on the ballast shell to increase the heat dissipation effect of the ballast by increasing the surface area of the ballast shell, or an external fan is added to assist the fins in heat dissipation. For example, a protective shell of an electronic ballast disclosed in a Chinese utility model patent with the patent publication number CN219499581U. This protective shell vertically arranges two groups of heat dissipation fins on the original ballast shell and uses a heat dissipation fan to accelerate the air flow around the heat dissipation fins, thereby improving the heat dissipation efficiency of the heat dissipation fins and realizing the high-efficiency heat dissipation function of the heat dissipation fins, so as to achieve the high-efficiency heat dissipation function of the protective shell;

[0003] When the above-mentioned protective shell of the electronic ballast is specifically used, although it drives the air flow around the heat dissipation fins through an external fan, the direction of the fan is perpendicular to the parallel interval of the fin group, and the air blown by the fan can only contact the nearest fin, and the air flow within the parallel interval of the fin group is still disordered, so that the heat dissipation effect of the fins cannot be effectively exerted, that is, the heat dissipation effect is not good. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above technical deficiencies, and propose a ballast heat dissipation shell to solve the technical problem of poor heat dissipation effect in the prior art.

[0005] To achieve the above technical purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a ballast heat dissipation shell, which includes a shell, inner fins, a drainage platform, a fan and a flow stabilizing plate. The inner fins are evenly distributed along the outer circumference of the shell. The drainage platform is arranged at the end side of the shell. The drainage platform has a taper, and the thick end of the drainage platform is adapted to the shell. The fan is arranged on the end side of the drainage platform far from the shell and is used for exhausting air outwards; the flow stabilizing plate covers above several of the inner fins, and the flow stabilizing plate is used to form a steady flow channel among several of the inner fins.

[0007] In some embodiments, the shell is in a cuboid shape, the inner fins are divided into four groups, and the four groups of inner fins are evenly distributed on four opposite faces of the shell, and several of the inner fins are parallel to each other.

[0008] In some embodiments, drainage sheets are evenly distributed on the outside of the drainage table. The drainage sheets are divided into four groups, and the drainage sheets located at the thick end of the drainage table in each group are connected to the adjacent inner fins.

[0009] In some embodiments, a drainage plate covers the top of each group of the drainage sheets. The drainage plate is used to form a drainage channel between several drainage sheets, and the drainage channel communicates with the steady flow channel.

[0010] In some embodiments, the drainage channel narrows from the thick end to the narrow end of the drainage table.

[0011] In some embodiments, an installation groove is formed in the center of the narrow end of the drainage table. The fan is fixedly installed in the installation groove, and a steady flow ring is sleeved outside the fan. The end side of the steady flow ring is fixedly connected to one side of the adjacent drainage plate.

[0012] In some embodiments, a protective net is provided on the end side of the steady flow ring facing away from the drainage plate.

[0013] In some embodiments, a number of outer fin rings are evenly arranged around the outside of the four groups of steady flow plates.

[0014] In some embodiments, chamfers are provided at the intersection of each two side walls of the housing, and support rods are vertically arranged on each chamfer of the outer shell. The other ends of the support rods in the same group are fixedly provided with support strips.

[0015] In some embodiments, an installation bin is slidably arranged in the outer shell.

A sealing plate is provided at the end side of the outer shell, and an elastic plug plate is provided on one side of the sealing plate close to the installation bin. The elastic plug plate abuts against the end side of the installation bin close to it.

[0016] Compared with the prior art, a ballast heat dissipation housing provided by the present utility model realizes the purpose of improving the heat dissipation effect by arranging a housing, inner fins, a drainage table, a fan and steady flow plates. During specific operation, the fan is started to drive the air flow. The air flow enters from the end side of the steady flow channel formed by the inner fins and the steady flow plates away from the drainage table. With the driving of the fan, the air flow flows through the drainage table and flows from the thick end to the thin end of the drainage table until it reaches one side of the fan, and finally is discharged through the fan.

[0026] Among them, the housing 100 is in a cuboid shape. The inner fins 200 are divided into four groups and are distributed on four opposite faces of the housing 100, and a plurality of inner fins 200 are all parallelly distributed;

[0027] In this embodiment, when the fan 400 is started, the air flow is driven by the fan 400. The air flow enters from the end side of the stable flow channel formed by the inner fins 200 and the flow stabilizer plate 500 away from the drainage platform 300.

[0030] In this embodiment, when the fan 400 exhausts air outwards, it drives the air to enter the drainage channel 330 through the stable flow channel 510, and the drainage channel 330 gradually narrows, increasing the flow rate and further ensuring the heat dissipation effect.

[0031] In one of the embodiments, please refer to Figures 3 - 4, an installation groove 340 is formed in the center of the narrow end of the drainage table 310. The fan 400 is fixedly installed in the installation groove 340, and a flow stabilizer ring 410 is sleeved outside the fan 400.

At the same time, the symmetrically arranged support bars 130 also facilitate the installation or placement of the device.

[0036] In one of the embodiments, please refer to Figure 4 , an installation bin 700 is slidably provided in the housing 100. The outer sides of the installation bin 700 are in contact with the inner wall of the housing 100, and a silicone grease pad 710 is provided on the outer side of the installation bin 700.

The fan 400 drives the air flow. The air flow enters from the end side of the steady flow channel 510 formed by the inner fins 200 and the steady flow plate 500 that is far away from the drainage table 300. And the drainage channel 330 gradually narrows to increase the flow rate, further ensuring the heat dissipation effect. Then, it flows through the drainage table 300, flows from the cone bottom to the cone top of the drainage table 300 until it is discharged through the fan 400. When the air flow flows through the above-mentioned components, it can quickly and stably take away the heat on them, thus ensuring a good heat dissipation effect.
