Description

Technical Field

[0001] The utility model relates to the technical field of switching power supplies, in particular to a fast-cooling switching power supply. Background Art

[0002] Switching mode power supply, also known as switching power supply, switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage level into the voltage or current required by the user through different forms of architecture. The input of the switching power supply is mostly AC power (such as mains) or DC power, and the output is mostly equipment that requires DC power, such as personal computers, and the switching power supply performs voltage and current conversion between the two.

[0003] The existing patent technology CN202121550779.6 proposes that existing switching power supplies are equipped with a heat dissipation structure to dissipate heat to prevent heat accumulation from causing excessive temperature and affecting the normal operation of the circuit or even damaging the circuit. However, the heat dissipation effect of the power device of the existing switching power supply needs to be further improved, and based on this, a switching power supply is proposed.

[0004] The switching power supply can press the power device against the inner wall of the shell through the pressing piece to achieve good thermal contact, so that the power device has a good heat dissipation effect, thereby improving the stability, reliability and efficiency of the circuit operation. However, the heat dissipation performance of the switching power supply mainly depends on the heat conduction of the shell to conduct the heat generated during the operation of the power supply to the outside to achieve heat dissipation performance. However, after the heat is conducted out, the contact area between the shell and the outside air is small, and the actual heat dissipation effect that can be achieved is relatively general. In addition, in the face of high-power working conditions, it is difficult to meet the heat dissipation requirements of the power supply. For this reason, we designed a fast cooling switching power supply to solve the above problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a switching power supply with rapid temperature reduction, which solves the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a fast cooling switching power supply, including an outer shell and a switching power supply body, the switching power supply body is sleeved in the outer shell, the inner side of the outer shell is sleeved with a heat conduction plate located above the switching power supply body, and the top of the outer shell is fixedly connected with two groups of symmetrically distributed fixing plates, the fixing plates and the heat conduction plates are connected with evenly distributed springs, the heat conduction plates are provided with evenly distributed heat sinks, the rear of the outer shell is fixedly installed with a guide cabin corresponding to the position of the switching power supply body, the outside of the guide cabin is equipped with a cold air unit, and the guide cabin is provided with evenly distributed injection ports.

[0007] Furthermore, the inner side of the outer shell is fixedly connected with evenly distributed limit seats, and the switching power supply body is sleeved on the inner side of the limit seats.

[0008] Furthermore, a gap is provided between the limiting seat and the outer shell, and the limiting seats are symmetrically distributed on both sides of the fixing plate.

[0009] Furthermore, a pull rod is movably mounted on the middle portion of the fixed plate, and a bottom end of the pull rod is fixedly connected to the top of the heat conducting plate.

[0010] Furthermore, evenly distributed fixing piles are connected to the bottom of the heat conducting plate, and positioning grooves matching the fixing piles are formed on the switching power supply body.

[0011] Furthermore, a cavity is provided in the flow guide cabin, and the cavity inside the flow guide cabin is connected to the cold air unit through a connecting pipe.

[0012] Furthermore, the distribution area of ​​the injection ports corresponds to the assembly positions of the switching power supply body and the heat conducting plate, and a terminal is provided on the outer side of the switching power supply body.

[0013] The utility model provides a fast cooling switching power supply, which has the following beneficial effects:

[0014] 1. The fast cooling switching power supply uses a heat conducting plate and a heat sink as well as a fixing pile and a positioning groove in coordination, so that after the switching power supply body of the fast cooling switching power supply is mounted on the inner side of the outer shell, the heat conducting plate can squeeze and limit the upper part of the switching power supply body under the action of the spring force. In the limited state, the fixing pile at the bottom of the heat conducting plate is embedded in the positioning groove on the switching power supply body, thereby ensuring the stability of the switching power supply body in the outer shell. At the same time, the heat generated during the operation of the switching power supply body can be introduced into the heat sink through the heat conducting plate, and the contact area with the air is expanded through the heat sink, thereby achieving a better heat dissipation effect.

[0015] 2. The fast cooling switching power supply, through the coordinated use of the cooling unit and the connecting pipe and the guide cabin and the injection port, enables the cooling unit to work and prepare cold air when the switching power supply body of the fast cooling switching power supply performs high-power work. The cold air is input into the guide cabin through the connecting pipe, and is ejected through the injection port opened on the guide cabin to act on the switching power supply body inside the outer shell. The cold air flows through the gap between the limit seat and the outer shell to achieve a comprehensive effect on the outside of the switching power supply body, so that the switching power supply body can achieve rapid cooling in a short time.

[0026] See also Figures 2 to 6 A pull rod 12 is movably mounted in the middle of the fixed plate 4.
