Description

Technical Field

[0001] This utility model relates to the field of commercial kitchen equipment technology, and in particular to a duct heat dissipation device and a commercial electromagnetic clay pot stove. Background Technology

[0002] As a core cooking equipment in the catering industry, the heat dissipation performance of commercial induction cookers directly affects the stability and energy efficiency of the equipment. Currently, under high-intensity operation, insufficient heat dissipation system efficiency often leads to abnormally high temperatures in critical internal components. This not only accelerates equipment aging and shortens its lifespan but may also pose safety hazards. Fundamentally, traditional heat dissipation ducts have design flaws in airflow organization and heat conduction, failing to effectively establish heat exchange circulation channels. This causes heat to stagnate within the cavity, ultimately limiting the improvement of overall heat dissipation efficiency.

[0003] The structural contradictions in the heat dissipation systems of existing commercial induction cooktops mainly manifest in localized heat accumulation caused by unreasonable airflow path planning, and heat dissipation lag caused by the mismatch between airflow pathways and heating element layout. Furthermore, redundant piping not only increases airflow resistance but also makes maintenance and cleaning difficult, further weakening the thermal management effect in actual use. These system defects collectively lead to the risk of thermal runaway when the equipment operates at continuous high power, severely restricting the reliability and operational efficiency of commercial kitchen appliances. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is the defects and deficiencies mentioned in the background art. It optimizes the heat transfer channel of commercial electromagnetic clay pot stove to solve the problems of heat accumulation and low heat dissipation efficiency of traditional equipment.

[0005] To address the above problems, the present invention proposes the following technical solutions:

[0006] A heat dissipation device includes a housing, a mounting frame, an electromagnetic core module, and an exhaust device; the housing is provided with a heat dissipation cavity, and the heat dissipation cavity is provided with an upper opening; the mounting frame is disposed on the upper opening of the heat dissipation cavity;

[0007] The electromagnetic core module is at least partially disposed within the heat dissipation cavity, and the electromagnetic core module is fixedly mounted on the mounting frame; the heat dissipation cavity is provided with a first air inlet and a first air outlet, and the exhaust device is disposed on the first air outlet.

[0008] A further technical solution is that the first air inlet is located at the bottom of the heat dissipation cavity, and the first air outlet is located at the rear side of the heat dissipation cavity.

[0009] A further technical solution is that the number of the first air inlets is multiple, and the multiple first air inlets are spaced apart at the bottom of the heat dissipation cavity;

[0010] There are multiple first air outlets, which are spaced apart on the rear side of the heat dissipation cavity.

[0011] A further technical solution is that the housing of the electromagnetic core module is provided with a second air inlet and a second air outlet, and the second air inlet and the second air outlet are connected to the heat dissipation cavity.

[0012] A further technical solution is that the second air inlet is located at the bottom of the electromagnetic core module, and the second air outlet is located on the side of the electromagnetic core module.

[0013] A further technical solution is that the number of the second air inlets is multiple, and the multiple second air inlets are spaced apart at the bottom of the electromagnetic core module;

[0015] A further technical solution is that the number of electromagnetic core modules is multiple, and the multiple electromagnetic core modules are spaced apart on the mounting frame.

[0016] A further technical solution is that the mounting frame is provided with multiple mounting ports, and multiple electromagnetic core modules are installed one-to-one in the multiple mounting ports.

[0019] Compared with the prior art, the technical effects achieved by the embodiments of this utility model include:

[0020] The air duct heat dissipation device provided by this utility model semi-embeds the heating component (electromagnetic core module) into a heat dissipation cavity with an upper opening, forming a three-dimensional assembly structure with the mounting frame. This allows the heat generated by the electromagnetic core to be directly introduced into the enclosed heat dissipation space. Combined with the axial airflow channel formed by the first air inlet and the first air outlet, and the active exhaust device configured at the air outlet, a unidirectional heat conduction path is formed from bottom air intake to top air exhaust. This utility model effectively solves the problem of heat accumulation under continuous high-load conditions in electromagnetic cooking equipment by constructing a directional airflow circulation system, and fundamentally avoids the disordered heat diffusion phenomenon present in traditional equipment, significantly improving heat dissipation efficiency.

[0021] The commercial induction cooker provided by this utility model, based on the aforementioned air duct heat dissipation device, features a nested layout of the electromagnetic core and heat dissipation cavity that shortens the conduction distance between the heat source and the heat dissipation channel, ensuring that heat is quickly removed from sensitive electronic components. The axially continuous air intake and exhaust system, combined with the active exhaust device, creates a stable negative pressure environment, enabling precise control of airflow speed and volume. The modular installation frame design ensures the integrity of the internal airflow path and provides convenient disassembly interfaces for daily maintenance.

[0031] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0032] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0033] See Figure 1-3 This utility model provides a duct cooling device to solve the problems of heat accumulation and low heat dissipation efficiency in traditional electromagnetic cooking equipment. As shown in the figure, the duct cooling device provided in this embodiment includes a housing 10, a mounting frame 20, an electromagnetic core module 30, and an exhaust device (not shown). The housing 10 is provided with a heat dissipation cavity 11, and the heat dissipation cavity 11 has an upper opening 12. The mounting frame 20 is disposed on the upper opening 12 of the heat dissipation cavity 11.

[0034] The electromagnetic core module 30 is at least partially disposed within the heat dissipation cavity 11, and the electromagnetic core module 30 is fixedly mounted on the mounting frame 20; the heat dissipation cavity 11 is provided with a first air inlet 13 and a first air outlet 14, and the exhaust device is disposed on the first air outlet 14.

[0035] In a specific embodiment, the exhaust device is a fan.

[0036] In this embodiment, the heating element (electromagnetic core module 30) is semi-embedded in a heat dissipation cavity 11 with an upper opening 12, forming a three-dimensional assembly structure with the mounting frame 20. This allows the heat generated by the electromagnetic core to be directly introduced into the enclosed heat dissipation space. Combined with the axial airflow channel formed by the first air inlet 13 and the first air outlet 14, and the active exhaust device configured at the air outlet, a unidirectional heat conduction path is formed from bottom air intake to top air exhaust. This embodiment effectively solves the problem of heat accumulation under continuous high-load conditions in electromagnetic cooking equipment by constructing a directional airflow circulation system, and fundamentally avoids the disordered heat diffusion phenomenon present in traditional equipment, significantly improving heat dissipation efficiency.

[0037] In a specific embodiment, the first air inlet 13 is located at the bottom of the heat dissipation cavity 11, and the first air outlet 14 is located at the rear side of the heat dissipation cavity 11. By placing the first air inlet 13 at the bottom 11 of the heat dissipation cavity and the first air outlet 14 at the rear, a directional heat convection path from bottom to top is formed. This embodiment utilizes the natural rising characteristic of hot air, combined with the forced suction of the rear exhaust device, to significantly improve airflow organization efficiency, avoid turbulence interference caused by traditional lateral air intake, and achieve rapid heat dissipation.

[0038] In a specific embodiment, the number of the first air inlets 13 is multiple (e.g., 8, 15, 30, etc.), and the multiple first air inlets 13 are spaced apart at the bottom of the heat dissipation cavity;

[0039] The number of the first air outlets 14 is multiple (e.g., 8, 15, 30, etc.), and the multiple first air outlets 14 are spaced apart on the rear side of the heat dissipation cavity.

[0040] In this embodiment, multiple first air inlets 13 are arranged at intervals at the bottom of the cavity, and together with multiple first air outlets 14 on the rear side, a distributed airflow network is formed. The number of outlets can be set according to actual heat dissipation requirements. By increasing the air inlet cross-sectional area and the diversion and exhaust paths, the air pressure distribution in the cavity is balanced, eliminating local heat dissipation dead zones, which is especially suitable for comprehensive heat dissipation of multiple heat source areas in high-power scenarios.

[0041] In a specific embodiment, the housing of the electromagnetic core module 30 is provided with a second air inlet 31 and a second air outlet 32, and the second air inlet 31 and the second air outlet 32 ​​are connected to the heat dissipation cavity 11.

[0042] In this embodiment, a second air inlet 31 and a second air outlet 32 ​​are added to the housing of the electromagnetic mechanism module 30 and connected to the main heat dissipation cavity, forming a dual-layer heat dissipation architecture with internal and external coordination. The internal air duct directly acts on the core heat-generating area of ​​the mechanism, while the external cavity air duct is responsible for overall heat exchange. The dual-layer design can shorten the heat conduction path and solve the problem of internal heat accumulation. Understandably, a fan can be installed inside the electromagnetic mechanism module 30 to exhaust the hot air from the electromagnetic mechanism module 30 into the heat dissipation cavity 11, and then exhaust the hot air out through the fan on the air outlet of the heat dissipation cavity 11.

[0043] In a specific embodiment, the second air inlet 31 is located at the bottom of the electromagnetic core module 30, and the second air outlet 32 ​​is located on the side of the electromagnetic core module 30.

[0044] In this embodiment, the second air inlet 31 is located at the bottom of the electromagnetic core module 30, and the second air outlet 32 ​​is located on the side of the electromagnetic core module 30, forming a longitudinal airflow channel that runs through the interior of the electromagnetic core module. This helps to utilize the cold air at the bottom to directly drive the heat source substrate, and combined with the lateral exhaust to guide the heat to escape laterally, effectively blocking the upward conduction of heat to the microcrystalline glass panel 40, and avoiding energy loss caused by overheating of the cooking surface.

[0045] In a specific embodiment, the number of second air inlets 31 is multiple (e.g., 8, 15, 30, etc.), and the multiple second air inlets 31 are spaced apart at the bottom of the electromagnetic core module 30; at least a portion of the first air inlets 13 and at least a portion of the second air inlets 31 are aligned with each other.

[0046] In this embodiment, the first air inlet 13 and the second air inlet 31 are partially aligned to connect the main air duct of the cavity with the sub-air duct of the mechanism. By reducing the number of airflow turning points and the points of sudden changes in air resistance, the system pressure loss is reduced, while ensuring that cold air is accurately injected into the dense area of ​​heat-generating components in the electromagnetic mechanism module 30, thus improving the targeted heat dissipation.

[0047] The electromagnetic mechanism module 30 is a plurality of modules, which are spaced apart on the mounting frame 20. The mounting frame 20 has a plurality of mounting ports 21, and the plurality of electromagnetic mechanism modules 30 are installed one-to-one in the plurality of mounting ports 21.

[0048] This embodiment utilizes multiple electromagnetic core modules 30 spaced apart on the mounting frame 30, combined with the modular design of the mounting port 21, to construct an independent heat dissipation unit. The airflow buffer zone reserved between each module can avoid the thermal field superposition effect. Combined with the parallel heat dissipation logic of the whole machine air duct system, it can achieve temperature balance control when multiple heat sources work in parallel, breaking through the capability bottleneck of the traditional series heat dissipation mode.

[0049] In a specific embodiment, the electromagnetic mechanism module 30 includes a plurality of electromagnetic heating units 33, which are evenly spaced on the upper side of the electromagnetic mechanism module 30; the air duct heat dissipation device also includes a microcrystalline glass panel 40, which covers the upper side of the electromagnetic mechanism module 30.

[0050] In a specific embodiment, each electromagnetic core module 30 includes two independently controlled electromagnetic heating units 33 to improve cooking flexibility and efficiency. The electromagnetic heating units 33 are evenly distributed on the upper side of the core, forming a sealed heat radiation interface with the microcrystalline glass panel 40. This solution reduces localized high-temperature points by uniformly distributing heat flow, while utilizing the high thermal conductivity and temperature resistance of the microcrystalline glass to ensure efficient heat transfer to the cookware. Excess heat is discharged through the upper and lower air ducts, achieving a dual optimization of cooking efficiency and heat dissipation performance.

[0051] This embodiment also provides a commercial electromagnetic clay pot stove, including the air duct heat dissipation device described above.

[0052] The commercial electromagnetic clay pot stove provided in this embodiment, based on the air duct heat dissipation device described above, allows cold air to enter from the bottom of the equipment, be heated by the core module, and then be discharged from the air outlets on the left and right sides of the module. At the same time, the rear fan operates to draw the hot air out of the equipment, forming a continuous airflow circulation, which effectively reduces the internal temperature of the equipment and ensures stable operation of the equipment.
