Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically to a power adapter housing with high-efficiency heat dissipation. Background Technology

[0002] With the continuous increase in the power density of electronic devices, the heat generation problem of internal circuit components in power adapters, as core components of energy conversion, is becoming increasingly prominent. Traditional power adapter housings typically employ a closed structure, relying on natural heat dissipation or simple heat sinks for passive cooling. However, due to the limited internal space and poor airflow, heat easily accumulates within the cavity, leading to excessively high temperatures in core components, resulting in performance degradation, shortened lifespan, or even failure. Furthermore, some designs attempt to enhance heat dissipation by adding ventilation holes to the housing or directly using external cooling fans, but these solutions have significant drawbacks: open structures allow dust and impurities to enter the housing, adhering to the circuit board surface and posing a short-circuit risk; while fans directly exposed near the circuit board, although accelerating airflow, struggle to guide airflow efficiently for heat exchange, exacerbating dust accumulation. Therefore, achieving a balance between efficient heat dissipation and dust protection within a limited space has become a technical challenge in power adapter structural design. Existing technologies urgently require an innovative solution that can rapidly dissipate heat through active cooling while preventing dust intrusion through physical isolation, to meet the stringent requirements of high-power, long-life electronic devices for power adapters.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See Figures 1 to 6 As shown, the structure of this utility model is as follows: a power adapter housing with high-efficiency heat dissipation, including an upper shell 1 and a lower shell 2 that are interlocked. A heat dissipation plate 3 is provided between the upper shell 1 and the lower shell 2. Heat dissipation fins 301 are provided on the heat dissipation plate 3. A cooling fan 4 is installed at one end of the heat dissipation fins 301. An air inlet 101 is provided on the upper shell 1 at the position corresponding to the air inlet of the cooling fan 4. A heat dissipation hole 102 is provided on the upper shell 1 at the position away from the air outlet of the cooling fan 4. Specifically, the upper shell 1 and the lower shell 2 are interlocked to form a closed main body, the interior of which... The circuit board is divided into an independent circuit chamber and a heat dissipation chamber by the heat sink 3. The heat generated by the circuit board is conducted to the heat dissipation fins 301 through the heat sink 3. After the cooling fan 4 is started, the external cold air is drawn into the heat dissipation chamber through the air inlet 101 and flows through the heat dissipation fins 301 to accelerate heat exchange. The hot air is finally discharged from the heat dissipation hole 102, which achieves dual optimization of efficient heat dissipation and dust protection. It not only uses the sealed circuit chamber to completely isolate dust intrusion and reduce the risk of short circuit, but also actively guides the heat dissipation chamber to quickly dissipate heat and ensure the stable operation of the components.

[0023] like Figure 1 , Figure 2 As shown, a dustproof net 5 is provided on the air inlet 101. The dustproof net 5 filters dust, hair and other particulate matter in the air through fine mesh to prevent them from entering the equipment.

[0024] like Figure 5 As shown, a groove 103 is provided on the upper shell 1 at the position corresponding to the dustproof net 5, which is used to accommodate the dustproof net 5 and to position the dustproof net 5.

[0025] like Figure 4 As shown, the dustproof net 5 is provided with a magnetic strip 501, and a magnetic strip 104 is installed in the groove 103 at the position corresponding to the magnetic strip 501. The dustproof net 5 is attracted together by the magnetic strip 501 and the magnetic strip 104 fixedly set in the groove 103, so that the dustproof net 5 can be removed for cleaning more conveniently.

[0026] like Figure 6 As shown, the inner wall of the lower shell 2 is provided with a step 6, and a threaded hole 601 is provided on the step 6. A mounting hole 302 is provided on the heat sink 3 at the position corresponding to the threaded hole 601. Specifically, the heat sink 3 is clipped on the step 6, and the heat sink 3 is firmly fixed on the step 6 by passing a screw through the mounting hole 302 and threading it with the threaded hole 601, so as to ensure that the heat sink 3 is installed stably.

[0027] like Figure 3 As shown, the bottom of the heat sink 3 is provided with an insulating thermal conductor 303. The insulating thermal conductor 303, such as a thermally conductive silicone pad or a thermally conductive potting compound, fills the micro gap between the electronic components and the heat sink 3, significantly increasing the effective contact area and reducing the interface thermal resistance. At the same time, its excellent electrical insulation can prevent current leakage or short circuit risks.

[0028] In practical use, when the power adapter is powered on, the electronic components on the internal circuit board, such as transformers and power transistors, begin to generate heat. This heat is conducted to the heat sink 3, making it the main area of ​​concentrated heat. After absorbing heat, the multiple heat dissipation fins 301 distributed on the surface of the heat sink 3, through the high thermal conductivity of the metal material, evenly diffuse the heat to the entire fin structure. The three-dimensional arrangement of the fins expands the original planar heat dissipation area into a multi-layered three-dimensional heat dissipation surface. At the same time, the cooling fan 4 generates directional airflow, drawing in ambient temperature air from the air inlet 101 on the upper shell 1. The airflow direction is consistent with the fin orientation. The parallel airflow forms a channel that runs through the gaps between the fins. When the high-speed airflow passes through the gaps between the densely arranged heat dissipation fins 301, it directly washes the surface of the fins. Forced convection heat exchange occurs between the air and the high-temperature fins. The heat stored in the fins is quickly transferred to the flowing air, forming an efficient heat exchange process. At this time, the cooling efficiency of the heat dissipation plate 3 is several times higher than that of simple natural heat dissipation. The high-temperature air that has absorbed heat is driven by the fan and discharged from the heat dissipation hole 102 along the preset airflow channel. The staggered layout of the air inlet hole 101 and the heat dissipation hole 102 forms a unidirectional airflow path, which avoids the hot air backflow and at the same time continuously introduces new cold air to maintain the heat dissipation efficiency.

[0029] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
