Description
Technical Field
[0001] The utility model belongs to the technical field of chargers, and relates to a charger with efficient and balanced heat dissipation. Background Art
[0002] In recent years, with the development and application of new energy technologies, chargers, as core components of new energy, have also encountered bottlenecks in heat dissipation improvement. Since chargers need to be convenient for users to carry and ensure good heat dissipation of electronic heating devices inside the chargers, using fans to assist in charger heat dissipation has become a trend in the industry's development.
[0003] However, the heat generated by traditional charger internal electronic devices fills the entire interior of the charger. Fan heat dissipation can only better disperse the heat around the inner side of the fan. For the space parts in the charger housing far from the fan, or the space parts far from the fan and located above the fan, the heat dissipation degree is relatively slow, resulting in the heat generated inside the charger not being dissipated in a timely, uniform, and efficient manner. The heat dissipation efficiency is low, the heat dissipation effect is not ideal, and it is easy to cause the internal electronic components to be burned out.
[0004] Therefore, how to use fans to achieve efficient and balanced heat dissipation of chargers and ensure the reliability and service life of charger use has become a very meaningful research topic. Summary of the Utility Model
[0005] The utility model provides a charger with efficient and balanced heat dissipation, aiming to solve the problems that the heat generated inside the existing charger cannot be dissipated in a timely, uniform, and efficient manner, with low heat dissipation efficiency, unsatisfactory heat dissipation effect, and easy burning of internal electronic components.
[0006] To achieve the above object, the utility model provides a charger with efficient and balanced heat dissipation, including a housing and an inner mold body of the charger. An inner mold body of the charger with an exhaust passage inside is erected inside the housing. A lower wind-blocking sheet is provided between the lower end face of the inner mold body of the charger and the inner side surface of the bottom of the housing, and an upper wind-blocking sheet is provided between the upper end face of the inner mold body of the charger and the inner side surface of the top of the housing. A fan is provided on one side inside the inner mold body of the charger, so that the air enters from one side of the housing, then connects to the exhaust passage and is discharged from the other side of the housing, forming a fast heat dissipation mode with a single exhaust path.
[0007] Preferably, the housing includes a lower housing, an upper housing, side panels, and side covers. Side panels and side covers are respectively provided on both sides of the lower housing. A detachable upper housing is provided on the lower housing. A number of air inlet through holes are provided on the side panels, and a number of air outlet through holes are provided on the side covers. The air outlet through holes are located on one side of the fan.
[0008] Preferably, there are two lower baffles, which are respectively arranged at both end parts of the inner mold body of the charger to block the exhaust air from flowing from the upper part of the upper shell; there are two upper baffles, which are respectively arranged at both end parts of the inner mold body of the charger to block the exhaust air from flowing from the lower part of the upper shell.
[0009] Preferably, a wire is connected to the inner mold body of the charger, and the end part of the wire is clamped and passed through the side panel.
[0010] Preferably, the two inner side surfaces of the casing are tightly attached and connected to the two outer side surfaces of the inner mold body of the charger. The inner mold body of the charger includes an inner mold bottom shell and an inner mold cover plate, and the inner mold cover plate is arranged on the inner mold bottom shell.
[0011] The beneficial effects of the present utility model compared with the prior art:
[0012] The present utility model provides a charger with efficient and balanced heat dissipation. By arranging the upper baffle and the lower baffle to partition the internal space of the casing, the heat inside the inner mold body of the charger will not flow back into the inner mold body of the charger after being blown out by the fan, avoiding the hot air circulation inside the casing, effectively blowing the heat out of the casing and dissipating it into the air, improving the utilization efficiency of the fan heat dissipation, enabling the exhaust air channel inside the entire inner mold body of the charger to be timely and evenly cooled, with good heat dissipation effect, and further reducing the temperature of the electronic components.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the description of this application in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.
[0023] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0024] To achieve the above object, an embodiment of the present utility model provides a charger with efficient and balanced heat dissipation. Refer to Figures 1-6 As shown, it includes a housing 1 and an inner mold body 2 of the charger. The inner mold body 2 of the charger with an exhaust air channel 3 inside is erected in the housing 1. A wind-blocking lower baffle 4 is provided between the lower end surface of the inner mold body 2 of the charger and the inner side surface of the bottom of the housing 1. A wind-blocking upper baffle 5 is provided between the upper end surface of the inner mold body 2 of the charger and the inner side surface of the top of the housing 1. A fan 6 is provided on one side inside the inner mold body 2 of the charger, so that the air enters from one side of the housing 1, then connects to the exhaust air channel 3 and is discharged from the other side of the housing 1, forming a fast heat dissipation mode with a single exhaust air path.
[0025] Regarding the heat reflux defect of the existing charger, where some of the hot air is reversed back into the top and bottom of the inner mold body 2 of the charger before being exhausted by the exhaust fan, this embodiment proposes a constructive design. The inner mold body 2 of the charger is redesigned into a shape with the function of an exhaust channel 3 to fit the casing 1, and a lower baffle 4 and an upper baffle 5 are respectively provided on the inner sides of the bottom and top of the casing 1. In this way, the heat reflux defect is effectively blocked, ensuring that the air enters from one side of the casing 1, then connects to the exhaust channel 3 and exits from the other side of the casing 1, forming a fast heat dissipation mode with a single exhaust path, which has the advantages of timely, balanced, and efficient heat dissipation.
[0026] Furthermore, the casing 1 includes a lower casing 7, an upper casing 8, side panels 9, and side covers 10. Side panels 9 and side covers 10 are respectively provided on both sides of the lower casing 7. The lower casing 7 is provided with a detachable upper casing 8. A number of air inlet through holes 11 are provided on the side panels 9, and a number of air outlet through holes 12 are provided on the side covers 10. The air outlet through holes 12 are located on one side of the fan 6. In addition to protecting the inner mold body 2 of the charger, other components are also connected and arranged inside and outside the casing 1. For example, the upper casing 8 can be provided with hanging hooks, and fasteners can be arranged inside the upper casing 8. The lower casing 7 is used to lift the inner mold body 2 of the charger by setting rivets, so that the heat dissipation on both sides of the casing 1 corresponds to both sides of the inner mold body 2 of the charger, guiding and accelerating heat dissipation. Among them, the lower casing 7 is fixedly welded to the lower baffle 4, and the upper casing 8 is fixedly welded to the upper baffle 5.
[0027] Furthermore, there are 2 lower baffles 4, which are respectively arranged at both ends of the two sides of the inner mold body 2 of the charger to block the exhaust air from flowing from the upper part of the upper casing 8; there are 2 upper baffles 5, which are respectively arranged at both ends of the two sides of the inner mold body 2 of the charger to block the exhaust air from flowing from the lower part of the upper casing 8. In this way, whether it is the exhaust air on one side of the fan 6 or the intake air on the other side, it will be correspondingly blocked by the upper baffles 5 at both ends of the top and the lower baffles 4 at both ends of the bottom, directly exhausting and dissipating heat from the electronic components inside the inner mold body 2 of the charger, achieving balanced heat dissipation.
[0028] Furthermore, a wire 13 is connected to the inner mold body 2 of the charger, and the end of the wire 13 is clamped and passed through the side panel 9.
[0029] Furthermore, the two inner sides of the casing 1 and the two outer sides of the inner mold body 2 of the charger are tightly and firmly connected in a fitting manner, and hot air will not reflux from here. The inner mold body 2 of the charger includes an inner mold bottom shell 14 and an inner mold cover 15. The inner mold cover 15 is provided on the inner mold bottom shell 14.
[0030] It should be noted that the inner mold body 2 of the charger is the layout of the internal electronic components of the existing charger, such as including a circuit board, a radiator, a filter, and a charging interface, etc., which will not be elaborated here.
[0031] In summary, the present utility model provides a charger with efficient and balanced heat dissipation. By arranging the upper baffle 5 and the lower baffle 4 to partition the internal space of the casing 1, the heat inside the inner mold body 2 of the charger will not flow back into the inner mold body 2 of the charger after being blown out by the fan 6, avoiding the hot air circulation inside the casing 1, effectively blowing the heat out of the casing 1 and dissipating it into the air, improving the utilization efficiency of the heat dissipation of the fan 6, enabling the exhaust passage 3 inside the entire inner mold body 2 of the charger to be timely and evenly cooled, with good heat dissipation effect, and further reducing the temperature of the electronic components.
