Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to an active heat dissipation type range hood power supply. Background Technology

[0002] Range hoods are electrical appliances used in home kitchens to effectively remove cooking fumes. They not only fulfill their functional purpose but also complement the aesthetics of modern kitchens. They are primarily used in hotels, restaurants, eateries, schools, government offices, and factories. Currently, most electrical appliances require switching power supplies to control their stable voltage output. Furthermore, with the development and innovation of power electronics technology, switching power supply technology is constantly evolving, resulting in switching power supplies that are widely used in various large electrical devices due to their small size, lightweight design, and high efficiency.

[0003] However, switching power supplies often generate a significant amount of heat during operation. If this heat cannot be dissipated in time, it will greatly affect the efficiency of the switching power supply and even accelerate its lifespan. Currently, most switching power supplies use materials with good heat dissipation properties for the casing or employ air cooling. The former's heat dissipation efficiency is not high enough, and air cooling requires ventilation holes, allowing cooking fumes to enter the power supply. Once inside, the fumes cool and adhere to the electronic components, greatly hindering their heat dissipation and causing them to overheat and be damaged. Therefore, it is necessary to improve the existing power supplies used in range hoods. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide an active heat dissipation range hood power supply, which can effectively solve the problems of low heat dissipation efficiency of existing range hood power supplies, easy entry of oil fumes into the power supply, affecting the heat dissipation of electronic components, and causing them to overheat and be damaged.

[0006] An active cooling range hood power supply includes a housing, a control module, a radiator, and a liquid cooling pipe. The housing has a accommodating cavity, the bottom of which has a first mounting area and a second mounting area. The second mounting area is located beside the first mounting area, and a through hole is provided on the inner side of the accommodating cavity. The control module is disposed in the first mounting area. The radiator is disposed in the second mounting area. The liquid cooling pipe includes a liquid cooling section, a liquid inlet, and a liquid outlet. The liquid cooling pipe is disposed at the bottom of the accommodating cavity. The liquid cooling section surrounds the edge of the first mounting area and is in close contact with the control module. Both the liquid inlet and the liquid outlet extend outward from the housing through the through hole.

[0007] As a preferred embodiment, both the outer surface of the outer shell and the inner surface of the accommodating cavity are coated with a first graphene layer.

[0008] As a preferred embodiment, the radiator is provided with multiple heat dissipation fins.

[0009] As a preferred embodiment, the surface of the heat sink is coated with a second graphene layer.

[0010] As a preferred embodiment, the liquid cooling pipe has a square cross-section.

[0011] As a preferred embodiment, the peripheral surfaces of the liquid cooling pipe are coated with a third graphene layer.

[0012] As a preferred embodiment, the housing includes a shell and a cover, the shell having the aforementioned receiving cavity, and the cover being disposed on the shell and completely covering the receiving cavity.

[0013] As a preferred embodiment, a first seal is formed at the mating point of the cover and the shell by applying adhesive.

[0014] As a preferred embodiment, a second seal is formed at the junction of the through hole and the liquid cooling pipe by applying adhesive.

[0015] As a preferred embodiment, there are two second installation areas, with each second installation area located on one side of the first installation area.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0031] Please refer to Figures 1 to 2 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a housing 10, a control module 20, a heat sink 30, and a liquid cooling pipe 40.

[0032] The outer casing 10 has a receiving cavity 11, the bottom of which has a first mounting area 12 and a second mounting area 13.

In addition, the outer casing 10 includes a shell 101 and a cover 102. The shell 101 has the aforementioned receiving cavity 11. The cover 102 is disposed on the shell 101 and completely covers the receiving cavity 11. A first sealing element 51 is formed at the mating point of the cover 102 and the shell 101 by applying adhesive. There are two second mounting areas 13, which are located on both sides of the first mounting area 12.

[0033] The control module 20 is located within the first installation area 12.

[0034] The heat sink 30 is disposed in the second mounting area 13; in this embodiment, the surface of the heat sink 30 is coated with a second graphene layer (not shown in the figure), and the heat sink 30 is provided with a plurality of heat dissipation fins 31.

[0035] The liquid cooling pipe 40 includes a liquid cooling section 41, an inlet 42, and an outlet 43. The liquid cooling pipe 40 is disposed at the bottom of the accommodating cavity 11. The liquid cooling section 41 surrounds the edge of the first mounting area 12 and is in contact with the control module 20.
