Heat dissipation structure of annular wire coil

Abstract

The utility model provides a heat dissipation structure of an annular wire coil, and relates to the induction cooker technology, in particular to the heat dissipation structure of the annular wire coil, which comprises an annular support structure and two closed structures arranged in pairs, and the two closed structures are respectively arranged on two sides of the support structure. The closed structure and the supporting structure are mutually spliced to jointly form an annular air duct; two through openings are formed in the outer side wall of one closed structure, and a fan communicated with the other through opening is installed in the other through opening. The fan introduces outside cold air into the annular air duct through the through opening, and meanwhile, the annular air duct guides heat accumulated between the two closed structures to the other through opening to be discharged; through the annular air duct structure, heat can be quickly discharged from the closed structure, so that the heat dissipation efficiency of the annular wire coil is improved; therefore, the problem that the working performance of the annular wire coil is affected by rapid temperature rise caused by heat accumulation in the machine shell is avoided, and the problem that the annular wire coil is burnt out possibly due to overheating is also prevented.

Description

Technical Field

[0001] This utility model relates to the field of induction cooker technology, and more specifically, to a heat dissipation structure of a ring-shaped coil. Background Technology

[0002] Currently, most common heating plates are used in conjunction with induction cookers, microwave ovens, or integrated hot pot and grill tables. The heating plate needs to be installed inside the casing and cannot be used independently.

[0003] When the electromagnetic coil is working, it generates an alternating magnetic field. When the pot, made of magnetically conductive material, is placed in this alternating magnetic field, the bottom surface of the pot cuts the alternating magnetic lines of force, generating alternating eddy currents at the bottom of the pot. These eddy currents cause the metal atoms at the bottom of the pot to move at high speed and randomly, thereby generating heat energy and heating the pot, thus heating the food inside. The resistance and magnetic reluctance of the electromagnetic coil and magnetic strip are significantly different at room temperature and high temperature. As the temperature rises, the resistance and magnetic reluctance increase, and the losses in the electromagnetic coil and magnetic strip gradually increase, which also causes the temperature of the electromagnetic coil and magnetic strip to rise. If the electromagnetic coil cannot effectively dissipate heat and cool down, the thermal efficiency of the electromagnetic coil will decrease with the rise in temperature, and there is even a risk of burning out the electromagnetic coil.

[0004] Therefore, when appliances operate at high power, the temperature of the internal coil rises rapidly. At the same time, the control board below the coil radiates a lot of heat. Due to the large diameter of the coil and the high heat generation, relying solely on natural heat dissipation or using a fan to blow directly onto the coil is not very effective in cooling the heating plate. Although it can ensure normal operation, the heating plate is still prone to burning out. In particular, when high-power commercial stoves operate under high load for a long time, if ventilation is not timely, the temperature inside the casing will rise sharply, seriously affecting the working efficiency of the heating plate and potentially causing the heating plate to burn out. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation structure for a ring-shaped coil, which addresses the shortcomings of existing technologies and solves the problems mentioned in the background.

[0006] The technical solution of this utility model is implemented as follows:

[0007] This utility model provides a heat dissipation structure for a ring-shaped coil, including a ring-shaped support structure and two paired closed structures, which are respectively installed on both sides of the support structure; the two closed structures and the support structure are spliced ​​together to form a ring-shaped air duct; two openings are opened on the outer wall of one of the closed structures, and a fan connected to it is installed in one of the openings.

[0008] In some technical solutions of this utility model, the closed structure includes two splicing plates, which are semi-circular in shape. A first splicing structure is provided at the splicing point of the two splicing plates, and a matching groove is opened on the side wall of each splicing plate.

[0009] In some technical solutions of this utility model, the first splicing structure includes a card plate and two limit blocks arranged in pairs. The two limit blocks are respectively disposed on the outer side wall of one of the splicing plates, and the card plate is disposed on the outer side wall of the other splicing plate. When the two splicing plates are spliced ​​together, the card plate is partially embedded between the two limit blocks.

[0010] In some technical solutions of this utility model, the support structure includes two splicing frames arranged in pairs. The splicing frames are semi-circular, and the splicing points of the two splicing frames are detachably connected.

[0011] In some technical solutions of this utility model, multiple bosses are arranged around the inner bottom wall of the settling tank, and through holes adapted to the bosses are opened on the side wall of the splicing frame.

[0012] In some technical solutions of this utility model, a number of locking plates are arranged around the sink trough, and locking chambers adapted to the locking plates are opened on the side wall of the splicing frame.

[0014] In some technical solutions of this utility model, an installation groove is opened on the side wall of the support structure away from the limiting protrusion.

[0015] Compared with the prior art, this utility model has at least the following advantages or beneficial effects: the opening introduces cold air from the outside into the annular air duct, and the annular air duct guides the heat accumulated between the two closed structures out through another opening. The annular air duct formed by the above structure can accelerate the heat dissipation between the two closed structures and accelerate the heat dissipation effect of the annular coil; it avoids the accumulation of heat in the casing, which would cause the temperature inside the casing to rise sharply, affecting the working efficiency of the annular coil and preventing the annular coil from being burned out.

[0025] Example

[0026] This utility model provides a heat dissipation structure for a ring-shaped coil, such as... Figures 1-6As shown, the device includes a ring-shaped support structure 3 and two paired closed structures 1, which are ring-shaped and match the support structure 3. The two closed structures 1 are installed on both sides of the support structure 3. The two closed structures 1 and the support structure 3 are joined together to form a ring-shaped air duct. Two openings 11 are opened on the outer wall of one of the closed structures 1, and a fan 4 is installed in one of the openings 11. When the fan 4 is started, the opening 11 without the fan 4 introduces cold air from the outside into the ring-shaped air duct. The ring-shaped air duct guides the heat accumulated between the two closed structures 1 out through the other opening 11. The ring-shaped air duct formed by the above structure can accelerate the heat dissipation between the two closed structures 1, thus accelerating the heat dissipation effect of the ring coil; it also prevents heat from accumulating inside the casing, causing a sharp rise in the temperature inside the casing, affecting the working efficiency of the ring coil, and preventing the ring coil from burning out.

[0027] In some technical solutions of this utility model, the closed structure 1 includes two splicing plates 2, which are semi-circular in shape. The two splicing plates 2 are joined to form a ring-shaped structure, and the cross-section of the splicing plate 2 is "U"-shaped. A first splicing structure is provided at the joint of the two splicing plates 2, which facilitates rapid assembly of the two splicing plates 2 and accelerates assembly efficiency. A matching groove is formed on the side wall of each splicing plate 2, and the groove is the "U"-shaped area of ​​the splicing plate 2.

[0028] In some technical solutions of this utility model, the first splicing structure includes a retaining plate and two paired limiting blocks 13. The two limiting blocks 13 are respectively disposed on the outer wall of one of the splicing plates 2. Each limiting block 13 is rectangular and integrally formed with the outer wall of the splicing plate 2. A retaining plate 12 is disposed on the outer wall of the other splicing plate 2 and integrally formed with the outer wall of the splicing plate 2. The distance between the two limiting blocks 13 is equal to the length of the retaining plate 12. When the two splicing plates 2 are spliced ​​together, the retaining plate 12 is partially embedded between the two limiting blocks 13, resulting in a relatively large static friction between them.

[0029] In some technical solutions of this utility model, the support structure 3 includes two splicing frames 16 arranged in pairs. The splicing frames 16 are semi-circular. After the two splicing frames 16 are spliced ​​together, they form a ring-shaped structure. The splicing frames 16 are integrally formed by injection molding. The splicing points of the two splicing frames 16 are detachably connected. When the two splicing frames 16 are spliced ​​together, the ends of the splicing frames overlap and are fastened with screws.

[0030] In some technical solutions of this utility model, multiple bosses 7 are arranged around the inner side of the sink, and through holes adapted to the bosses 7 are opened on the side wall of the splicing frame 16. The above structure can position the closed structure 1 on the supporting structure 3 and prevent the closed structure 1 from shaking or misaligning on the supporting structure 3, thus affecting the airtightness of the annular air duct.

[0031] In some technical solutions of this utility model, a plurality of locking plates 8 are arranged around the inner bottom wall of the settling tank, and locking chambers 9 adapted to the locking plates 8 are opened on the side wall of the splicing frame 16. The locking plates 8 are configured as snap-fit ​​structures with barbs, and the locking plates 8 have a notch in the middle. During installation, the two ends of the locking plates 8 are pressed closer to each other by the inner wall of the locking chamber 9, while applying a counter-pushing force to the inner wall of the locking chamber 9, making the two contacts more tightly. The above structure can increase the connection strength between the closed structure 1 and the supporting structure 3.

[0032] In some technical solutions of this utility model, a plurality of limiting protrusions 10 are arranged around the side wall of the support structure 3, and any two adjacent limiting protrusions 10 have a limiting gap. The coil can be embedded in the limiting gap through the limiting protrusions 10, so that the coil does not misalign on the support structure 3, and a regular disc-shaped coil structure can be wound on the annular support structure 3 through the limiting protrusions 10.

[0033] In some technical solutions of this utility model, an installation groove 15 is formed on the side wall of the support structure 3 away from the limiting protrusion 10. The installation groove 15 facilitates the embedding of the magnetic pole strip, provides an installation position for the magnetic pole strip, makes the above structure more compact, and improves space utilization.

[0034] Four mounting holes are provided on the side wall of one of the closed structures 1. Guide rods 5 are installed in each mounting hole. Limiting springs 6 are provided on the guide rods 5. When the annular coil heat dissipation structure is installed in the housing, the limiting springs 6 can push the annular coil heat dissipation structure to fit into the surface to be heated, so that there is no gap at the fit point, and the separation of the two is avoided, which would affect the heating effect of the annular coil on the surface to be heated.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
