Description

Technical Field

[0001] This utility model relates to the field of switching power supply technology, and in particular to a multi-protection switching power supply module. Background Technology

[0002] In today's rapidly evolving electronic devices, switching power supply modules, as a crucial component of various electronic devices, are of paramount importance in terms of performance and stability. However, existing switching power supply modules still face numerous challenges in practical applications.

[0003] Traditional switching power supply modules typically employ a single air-cooling method, which may be sufficient for heat dissipation during low-power operation. However, with the continuous increase in the power of electronic devices and the extension of operating time, simple air cooling is no longer effective in dissipating the large amount of heat generated by the module. Excessive temperature not only affects the performance of the power supply module, leading to unstable output, but also significantly shortens its lifespan and increases the risk of equipment failure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-protection switching power supply module.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-protection switching power supply module includes an upper housing and a lower housing, and a PCB fixedly installed in the lower housing. The upper housing has an upper heat dissipation vent and an opening, and several mounting tubes are vertically arranged on the lower top surface of the upper housing. A heat absorption tube is arranged on the upper surface of the PCB and is fixed to the PCB by several clips. The module also includes a housing installed in the upper housing, with the housing corresponding to the opening. A liquid filling tube is arranged on the housing and communicates with the interior of the housing. A tube cap is threaded at the end of the liquid filling tube. The module also includes a liquid pump installed inside the upper housing. The liquid pump inlet is connected to the housing through a connecting tube, and the liquid outlet of the connecting tube is connected to a liquid injection tube. The module also includes a cooling fan arranged on several mounting tubes. A gap is provided between the cooling fan and the top of the upper housing. A heat dissipation tube is arranged in the gap between the cooling fan and the upper housing, and one end of the heat dissipation tube is connected to the housing.

[0007] Preferably, a lower heat dissipation vent is provided at the bottom of the lower housing.

[0008] Preferably, a first connecting hose and a second connecting hose are respectively provided at both ends of the heat absorption tube.

[0011] Preferably, the heat absorption tubes are evenly distributed around the electronic components on the PCB, and the clips are fixed to the PCB with hot melt adhesive.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model adopts a combination of liquid cooling and air cooling. It absorbs heat from the PCB through heat absorption tubes and dissipates heat quickly through coolant circulation and cooling fan action, effectively reducing the operating temperature of the switching power supply module, ensuring stable operation under high load, and extending its service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A multi-protection switching power supply module includes an upper housing 1, a lower housing 2, and a PCB 3 fixedly disposed within the lower housing 2. The upper housing 1 is provided with an upper heat dissipation vent 101 and an opening 102. Several mounting tubes 103 are vertically disposed on the lower top surface of the upper housing 1. A heat absorption tube 10 is disposed on the upper surface of the PCB 3 and is fixed to the PCB 3 by several clips 11. The module also includes a housing 4 disposed within the upper housing 1, the housing 4 corresponding to the opening 102, and a liquid filling tube 4 disposed on the housing 4. 01. The liquid filling pipe 401 is connected to the interior of the housing 4, and a pipe cap 402 is threaded at the end of the liquid filling pipe 401; it also includes a liquid pump 6 installed inside the upper housing 1, the liquid pump 6 inlet is connected to the housing 4 through a connecting pipe 5, and the liquid outlet of the connecting pipe 5 is connected to a liquid injection pipe 7; it also includes a cooling fan 9 installed on several mounting pipes 103, a gap is provided between the cooling fan 9 and the top of the upper housing 1, a heat dissipation pipe 8 is provided in the gap between the cooling fan 9 and the upper housing 1, and one end of the heat dissipation pipe 8 is connected to the housing 4.

[0025] In this embodiment, the air between the upper housing 1 and the lower housing 2 is drawn out by the cooling fan 9 to achieve air convection for heat dissipation. When air convection cannot meet the heat dissipation requirements, coolant is injected into the housing 4 through the liquid filling pipe 401. The coolant flows into the heat absorption pipe 10 under the action of gravity, or the coolant in the housing 4 is pumped into the heat absorption pipe 10 by the liquid pump 6. The liquid pump 6 can be directly connected to the PCB3 for power supply. When using liquid cooling, the coolant is circulated by the liquid pump 6. When the coolant flows through the heat absorption pipe 10, it can carry away the heat on the PCB3. When the high-temperature coolant passes through the heat dissipation pipe 8, the temperature of the coolant in the heat dissipation fan 9 can be reduced due to the action of the cooling fan 9, thereby achieving continuous cooling.

[0026] In this utility model, a lower heat dissipation vent 201 is provided at the bottom of the lower housing 2.

[0027] In this embodiment, by setting the lower heat dissipation vent 201, the air pressure in the space between the upper housing 1 and the lower housing 2 can be balanced when the cooling fan 9 is working.

[0028] In this utility model, a first connecting hose 12 and a second connecting hose 13 are respectively provided at both ends of the heat absorption tube 10. The heat absorption tube 10 is made of a rigid material with good thermal conductivity, and the first connecting hose 12 and the second connecting hose 13 are rubber hoses.

[0029] In this embodiment, the first connecting hose 12 and the second connecting hose 13 are used to facilitate the disassembly and installation of the upper housing 1 and the lower housing 2, making the installation relatively convenient.

[0030] In this invention, the other end of the heat dissipation pipe 8 is matched with the second connecting hose 13, and the heat dissipation pipe 8 is made of a hard material with good thermal conductivity.

[0031] In this embodiment, the heat pipe 8 is made of a material with good thermal conductivity, which can improve the heat absorption effect of the heat pipe 8.

[0032] In this invention, the injection tube 7 is matched with the first connecting hose 12, and the injection tube 7 is made of a hard material with poor thermal conductivity.

[0033] In this embodiment, the injection pipe 7 is made of a material with poor thermal conductivity, which can reduce the impact of external temperature on the coolant when discharging coolant.

[0034] In this invention, the heat absorption tubes 10 are evenly distributed around the electronic components of the PCB3, and the clips 11 are fixed to the PCB3 with hot melt adhesive.

[0035] In this embodiment, by evenly distributing the heat absorption tubes 10 around the electronic components, the heat generated by the electronic components can be absorbed to the maximum extent. The buckle 11 is fixed to the PCB3 with hot melt adhesive, which can facilitate later maintenance and will not damage the PCB3.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
