Description

Technical Field

[0001] The utility model relates to the field of semiconductors, in particular to a non-heating conductor closed heating flat plate structure. Background Art

[0002] With the development of modern society, products are becoming increasingly diverse, and heating plate technology is widely used in their production. Heating plates are devices that convert electrical energy into thermal energy and are widely used across various industries. Currently, heating plates are common in the chip, chemical, pharmaceutical, and food industries, and are often used for heating, welding, drying, and other applications.

[0003] Common heating plates mostly use heating conductors / heating elements, such as those based on resistance heating and heat transfer. Heating elements are typically distributed throughout the heating plate, and the surface is typically covered with a material with high thermal conductivity, such as stainless steel or aluminum alloy. The heating elements convert electrical energy into heat energy, which is then transferred to the object being heated via the thermally conductive material.

[0004] Heating plates using heating conductors / heating elements are also widely used in industry. They can meet the heating needs of most products. However, heating plates also have the following disadvantages:

[0005] 1. The heating rate is slow. Due to the slow heating rate of the heating plate, users generally keep the heating plate on to cope with product production, which will cause energy waste for users. Due to the distribution of heating conductors within the heating plate and power limitations, for products that require segmented heating, users may need to prepare multiple heating plates for heating, which have no contact with the heat conduction layer.

[0006] 2. The heating plate has insufficient heating uniformity. The uneven distribution of heating elements inside the heating plate will result in poor heating of the product.

[0007] 3. The heating efficiency of the heating plate is low. Only 30%-70% of the general energy consumption of the heating plate is converted into working heat energy.

[0008] 4. It cannot be used in flammable, explosive and corrosive environments.

[0009] 3. Inductive heating is difficult to temperature control and requires professional tools to control its temperature. Utility Model Content

[0010] The Summary of the Utility Model introduces a series of simplified concepts, which are simplifications of existing technologies in the field and are further described in detail in the Detailed Description of the Utility Model. The Summary of the Utility Model of this utility model is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0011] The technical problem to be solved by the utility model is to provide a device with a fast heating rate, a large heating range, high heating efficiency, uniform heating, and applicable to various materials and capable of realizing segmented heating.

[0012] In order to solve the above technical problems, the utility model provides a non-heating conductor enclosed heating flat plate structure, comprising:

[0013] an anti-scratch and anti-wear layer 2 formed on the bottom surface of the heat conducting layer 3;

[0014] a heat conducting layer 3 formed on the top surface of the closed shell 1;

[0015] a temperature-resistant insulating layer 4 formed on the bottom surface of the heat-conducting layer 3;

[0016] A plurality of non-contact electrothermal conversion units 5 are evenly distributed below the heat conducting layer 3 , and are used to convert electrical energy into thermal energy to heat the heat conducting layer 2 , without contact with the heat conducting layer 3 .

[0017] Preferably, the non-heating conductor enclosed heating flat plate structure is further improved to include:

[0018] The liquid detection sensor 6 is arranged at the bottom of the closed shell 1, and cuts off the input power when it detects water leakage.

[0019] Preferably, the non-heating conductor enclosed heating flat plate structure is further improved to include:

[0020] The temperature sensor 7 is formed on the anti-scratch and anti-wear layer 2 and is used to measure the real-time temperature of the anti-scratch and anti-wear layer 2 .

[0021] Preferably, the non-heating conductor enclosed heating flat plate structure is further improved, and the temperature sensor 7 is a thermocouple.

[0022] Preferably, the non-heating conductor enclosed heating flat plate structure is further improved to include:

[0023] Analog converter, which converts the temperature sensor signal from analog to digital and sends it to the external PLC;

[0024] The external PLC controls the heating power of the non-contact electrothermal conversion unit 5 to achieve real-time monitoring of the temperature of the heating plate.

[0025] Preferably, the non-heating conductor enclosed heating flat plate structure is further improved, and the anti-scratch and anti-wear layer 2 is a metal chromium layer.

[0026] Preferably, the non-heating conductor enclosed heating flat plate structure is further improved, and the heat conducting layer 3 is an oxygen-free copper layer.

[0027] Preferably, the non-heating conductor enclosed heating flat plate structure is further improved, and the non-contact electrothermal conversion unit 5 is an inductor.

[0028] Preferably, the non-heating conductor enclosed heating flat plate structure is further improved, and the inductor is a hollow structure with cooling water flowing into the interior.

[0029] Preferably, the non-heating conductor closed heating flat plate structure is further improved, and a sealing member 8 is arranged at a position where the non-contact electrothermal conversion unit 5 passes through the closed shell 1 .

[0030] To avoid the drawbacks of heating conductors / heating elements with flat heating plates, non-contact electrothermal conversion is an alternative. Non-contact electrothermal conversion is a method of converting electrical energy into thermal energy without requiring direct contact between the heating element and the object being heated. This conversion is typically based on electromagnetic induction or radiation. Common non-contact electrothermal conversion technologies include electromagnetic induction heating, radio frequency (RF) heating, microwave heating, infrared (IR) heating, solar thermal conversion, electrothermal film heating, and inductively coupled power transfer (ICPT).

[0031] Induction heating is a form of electromagnetic induction heating. It primarily uses electromagnetic induction to generate current in the object being heated, relying on eddy current energy to heat the object. The inductor coil is connected to a power source, which provides an alternating current to the coil. This current flows through the coil, generating an alternating magnetic field on the surface of the heated object, causing eddy currents to generate heat. Induction heating is also common in industry, but it also has the following disadvantages:

[0032] 1. Only suitable for heating metal products. Inductive heating mainly uses the principle of electromagnetic induction. Therefore, it is only suitable for heating metals.

[0033] 2. Inductive heating cannot be used in flammable, explosive or corrosive environments. Electric sparks may cause the inductive coil to short-circuit.

[0034] 3. Inductive heating is difficult to temperature control and requires professional tools to control its temperature.

[0035] Therefore, induction heating cannot be simply and directly applied to the heating plate. The utility model designs a closed shell 1, an anti-scratch and anti-wear layer 2, a heat conductive layer 3 and a temperature-resistant insulating layer 4 in conjunction with inductance to realize a non-heating conductor closed heating plate.

[0036] In a preferred embodiment of the present invention, a temperature sensor measures the real-time temperature and converts this signal into an analog signal, which is then fed into an analog converter. The analog converter converts the analog value into a digital value and transmits it to a PLC, which controls the heating power of the inductor, thereby enabling real-time monitoring of the heating plate temperature. Furthermore, a liquid detection sensor is built into the heating plate. If the inductor coil leaks, the heating plate immediately shuts off power and stops operating, ensuring safe operation.

[0037] The utility model has the following technical effects:

[0038] 1. The heating rate is fast. The heating solution of this utility model no longer requires a constantly open heating plate to heat the product, which greatly reduces energy waste for users.

[0039] 2. The heating range is large, and the heating solution of the utility model can be applied to products with different temperature requirements.

[0040] 3. The heating solution of the present invention can support segmented heating.

[0041] 4. The heating scheme of the utility model has high heating efficiency, and generally 95% of the electrical energy is converted into thermal energy.

[0042] 5. Compared with heating by a heating plate, the heating scheme of the present invention can heat up more evenly.

[0043] 6. The heating solution of this utility model is suitable for heating products made of various materials (such as rubber, liquid, etc.).

[0044] 7. The heating scheme of this utility model is suitable for flammable, explosive and corrosive environments. BRIEF DESCRIPTION OF THE DRAWINGS
