Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a rectifier module. Background Art

[0002] High-temperature plasma is a substance with a flame-like high temperature produced by high-pressure ionized air. It can be used in various electrical appliances that need to be heated. However, since household voltage is generally 220V, which cannot meet the voltage required for ionized air, a transformer rectifier module is usually required to rectify the household 220V AC into high-voltage DC. Rectifier modules are often used in plasma stoves in kitchens, and kitchens are relatively humid environments. Waterproof and moisture-proof measures need to be taken for the rectifier circuit board of the rectifier module to prevent moisture from affecting the rectifier circuit board. A relatively closed environment will cause the heat generated by the rectifier circuit board during operation to be unable to be quickly discharged, thereby affecting the normal operation of the rectifier module. Utility Model Content

[0003] In view of this, the utility model provides a rectifier module, which is used to solve the problem in the prior art that heat of the rectifier module cannot be quickly discharged.

The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0023] See attached Figure 1 -Attached Figure 2 This embodiment discloses a rectifier module, which includes a containing box 20 and a rectifier circuit board 21; the rectifier circuit board 21 is fixed in the containing box 20, and a potting glue 23 is laid in the containing box 20.

[0024] Specifically, the potting glue 23 is a heat-conducting potting glue. By filling the potting glue 23 around the rectifier circuit board 21, the rectifier circuit board 21 is dustproof and waterproof insulated and supported to prevent the rectifier circuit board 21 from being affected by external moisture. The heat conductivity of the potting glue 23 allows the heat generated by the operation of the rectifier circuit board 21 to be dissipated to the housing box 20 through the potting glue 23. In actual application, the housing box 20 can be quickly cooled by air cooling, water cooling, etc., so as to achieve the purpose of heat dissipation of the rectifier module; the housing box 20 is a long strip structure, and the housing box 20 is provided with There is a receiving groove 200 with an opening on one side, and the receiving groove 200 is correspondingly opened as a long strip-shaped groove. The long strip-shaped receiving groove 200 allows the rectifier circuit board 21 to be designed as a long strip, avoiding the stacking of multiple rectifier circuit boards 21 in the receiving groove 200 to affect the filling of the potting glue 23 and the rapid dissipation of heat. At the same time, it also makes the long strip rectifier module have a wider range of application scenarios and can be used in small electrical appliances; in order to facilitate the rectifier circuit board 21 to be fixed in the receiving groove 200, symmetrical card slots 22 are provided on the opposite side walls of the receiving groove 200, and the two ends of the rectifier circuit board 21 are respectively connected with the two card slots 22.

[0025] In summary, during assembly, first, the rectifier circuit board 21 is installed on the card slot 22 in the receiving groove 200, and one end of the wire connected to the rectifier circuit board 21 is placed outside the receiving box 20 through the opening of the receiving groove 200, and then the potting glue 23 is filled into the receiving groove 200 through the potting process. After the potting glue 23 is cured, the rectifier module can be installed on the corresponding electrical appliance for use. Since the rectifier module seals the rectifier circuit board 21 with the potting glue 23, it plays a role of waterproof and moisture-proof. By filling the entire receiving groove 200 with the potting glue 23, it can also support and shockproof the rectifier circuit board 21. The thermal conductivity of the potting glue 23 itself allows the heat generated during the operation of the rectifier circuit board 21 to be quickly conducted to the receiving box 20 through the potting glue 23, and discharged through the receiving box 20, thereby avoiding the influence of heat accumulation in the receiving groove 200 for a long time on the rectifier circuit board 21.

[0026] See attached Figure 2 The card slot 22 is arranged close to the bottom wall of the accommodating slot 200, so that the electronic components laid on the front of the rectifier circuit board 21 have more accommodating space, which is convenient for the installation of the rectifier circuit board 21 and avoids the rectifier circuit board 21 from being bumped during assembly. At the same time, the potting glue 23 can effectively cover the rectifier circuit board 21 and its electronic components, ensuring the airtightness of the rectifier circuit board 21 and avoiding moisture.

[0027] In order to further improve the complete coverage of the rectifier circuit board 21 by the potting glue 23, the card slot 22 includes an inner slot 221 and an outer slot 222. The inner slot 221 and the outer slot 222 are spaced apart, and the outer slot 222 is arranged close to the opening of the receiving slot 200. By dividing the card slot 22 into two, the contact area between the card slot 22 and the rectifier circuit board 21 is reduced, so that there is a gap between the side end of the rectifier circuit board 21 and the inner wall of the receiving slot 200, so that the potting glue 23 can cover the side end of the rectifier circuit board 21.

[0028] See attached Figure 2 The top and bottom of the container box 20 are provided with heat dissipation fins 201, and the heat dissipation fins 201 extend along the length direction of the container box 20. By arranging the heat dissipation fins 201 on the container box 20, after the rectifier module is applied to the electrical appliance, the container box 20 can be cooled by a cooling fan, and the heat dissipation fins 201 can dissipate the heat faster.

[0029] In order to facilitate the assembly of the rectifier module to the corresponding electrical appliance, a plurality of connecting threaded holes 202 are provided on the top of the housing box 20. The number and positions of the connecting threaded holes 202 can be set according to the electrical appliance actually used.

[0030] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model.
