Description

Improved cooling structure

technical field

The utility model relates to an improved heat dissipation structure, especially to prevent finger insertion from causing injury, and avoid dust from entering and affecting the work of products installed or used on the bottom plane, such as power supplies, electromechanical boxes, and CNCs. The main machine, air conditioner, uninterruptible power system and other large equipment can play a role.

Background technique

Generally, most of the existing cooling devices are installed on the top or side of the machine, as shown in Figure 1, the power supply is formed by connecting a cover 1 and a lower cover 2, the cover 1 A hollow hole 11 can be opened on the top plate, so that a heat dissipation fan 3 can be installed to form a circulating air flow to the circuit board to assist heat dissipation. However, the existing heat dissipation fan 3 is installed on the top plate of the cover body 1, so that dust is easy to accumulate In the power supply, it is not easy to discharge, and it is easy to reduce the heat dissipation efficiency for a long time, and the hollow hole 11 is provided on the top plate of the cover body 1, which is easy to insert fingers and cause injury. In view of this, how to get rid of the above defects is: The technical difficulties that the utility model designer of this case wants to solve; therefore, based on years of experience in related product design, the utility model designer of this case feels the inconvenience of the above-mentioned traditional products. After years of painstaking research, trial production and improvement, finally Many shortcomings of the existing cooling device can be eliminated, and the project has been successfully developed.

Contents of the invention

The main purpose of this utility model is to provide an improved heat dissipation structure to overcome the above defects.

In order to achieve the above purpose, the utility model has an improved heat dissipation structure, which includes a fan placed at the bottom of the casing, connected to the power supply provided by the circuit board module, and a vent is provided at the bottom of the casing, and a safety device ( Such as hollow coils, filter screens, etc.), several tripods are set on both sides of the bottom of the shell, and the tripods can be screw-locked tripods, and a gap is set on the tripods to facilitate locking, so as to prevent fingers from being inserted and cause injuries. Avoid the entry of dust, which will affect the performance of large-scale equipment such as power supplies, electromechanical boxes, CNC machine tools, air conditioners, and uninterruptible power systems that are installed or used on the bottom plane.

Compared with the prior art, the utility model has the beneficial effect that the fan is placed at the bottom of the shell to prevent fingers from being inserted and causing injury;

Secondly, there are several tripods on both sides of the bottom of the casing to prevent dust from entering and affecting the performance of the power supply.

Detailed ways

The above-mentioned and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

Please refer to Fig. 2 and shown in Fig. 3, the utility model is provided with an air vent 100 by the bottom of a housing 10, and several perforations 101 are arranged at the bottom of the housing 10, and a hollow coil 20 is locked outside the air vent 100, and the housing 10 Combined with a top cover 30, wherein the side of the top cover 30 is provided with a number guide hole 301, and the side of the casing 10 is also provided with a number guide hole 301 in conjunction with the top cover 30, a circuit board module 40 is fixedly connected to the top cover 30, and the circuit board The surface of the module 40 is provided with necessary electronic components for power supply control, and at least one surface is coupled to a connection seat 50 , and a seat hole 501 is defined in the upper cover 30 for its accommodating or protruding.

Wherein, several tripods 15 are arranged on both sides of the bottom of the casing 10, and the tripod 15 and the casing 10 are locked by screws 151, and a gap 150 is set on the tripod 15 to facilitate locking the body. One end of the tripod 15 is connected to the bottom of the casing 10 Parallel, and a slope 152 is bent at the center of both ends, which can raise the casing 10 and keep a gap between the fan 60 and the body, so as to prevent the finger from being inserted, causing injury, and preventing dust from entering, which will affect the installation or use at the bottom. Two-dimensional products such as power supplies, electromechanical boxes, CNC machine tools, air conditioners, uninterruptible power systems and other large equipment can play a role.

To sum up, this utility model has indeed achieved the desired enhanced effect under the breakthrough of the previous technical structure, and has met the application requirements for a new model patent, and a new model application is filed according to law.

The above description is only illustrative, rather than restrictive, of the present invention. Those of ordinary skill in the art understand that many modifications and changes can be made without departing from the spirit and scope defined by the following appended claims. Or equivalent, but all will fall within the protection domain of the present utility model.
