Abstract

Technical Field

Background Art
[0002] A cross-flow fan, also known as a transverse-flow fan, is a type of fan designed to generate a wide and uniform air flow. Through its design, a cross-flow fan can generate a strong air flow. When used in conjunction with a heating plate, it can quickly disperse the heat generated by the heating plate into the air, thereby improving the overall heating efficiency. The existing heating modules used in cross-flow fans are generally conventional heating wires, and most conventional heating wires are made of metal alloys, with relatively low heating efficiency. Moreover, most conventional heating wires need to be installed in a fixed form, which is inconvenient to use. Therefore, we have improved the heating module of the cross-flow fan and proposed a new heating plate solution.

Detailed Embodiment
[0016] The embodiments of the utility model are described in detail below. The illustrated embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout.
[0017] In the utility model, unless otherwise clearly defined and limited, terms such as "assembled", "connected", and "joined" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected or connected through an intermediate medium, and it can be connected through the inside of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.
[0018] The technical solution and its beneficial effects of the utility model will be made clearer and more definite by further describing the specific embodiments of the utility model in conjunction with the drawings of the specification. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model and should not be construed as a limitation to the utility model.
[0019] The preferred embodiment provided by the utility model: As Figure 1 And Figure 3As shown in the figure, a rare earth heating plate structure of a fan includes a first insulating layer 1, a conductive heating layer 2, a second insulating layer 3, a mesh cover fixing plate 4 and a wiring board 5; the wiring board 5 is installed on the mesh cover fixing plate 4, and the wiring board 5 is connected to the conductive heating layer 2 to supply current to the conductive heating layer 2 to generate heat. The mesh cover fixing plate 4 is installed with a thermostat 6, and the wiring board 5 is connected to the thermostat 6. The mesh cover fixing plate 4 serves as a base for the first insulating layer 1 to be painted and cured, the conductive heating layer 2 is painted and cured on the first insulating layer 1, and the second insulating layer 3 is painted and cured on the conductive heating layer 2, so that the conductive heating layer 2 is located between the first insulating layer 1 and the second insulating layer 3;
[0020] The first insulating layer 1 is a blue paste insulating layer, the second insulating layer 3 is a carbon paste insulating layer, the conductive heating layer 2 includes a silver paste layer 21 and a heating screen printing coating 22, the heating screen printing coating 22 is connected to the silver paste layer 21, the silver paste layer 21 is connected to the wiring board 5, and the heating screen printing coating 22 is connected to the wiring board 5 through the silver paste layer 21 to introduce current, and the silver paste layer conducts electricity without generating heat.
[0021] Furthermore, the heating screen printing coating 22 is divided into several sections to match the shape of the mesh cover fixing plate 4; the silver paste layers 21 are respectively arranged at both ends of the heating screen printing coating 22, and each section of the heating screen printing coating 22 is connected to the silver paste layer 21, so that the silver paste layer 21 and the heating screen printing coating 22 form a loop, and the positive and negative poles of the wiring board 5 are connected to the silver paste layer 21 to supply current. The silver paste layer 21 serves as a conductive function, and the heating screen printing coating 22 is made of a high-resistance metal material. The heat generated by the heating screen printing coating is concentrated in the central area of the mesh cover fixing plate 4. The blue paste material uses the dielectric paste of 07H-1114 from Shenzhen Saiya Electronic Paste Co., Ltd., the silver paste layer 21 uses 01H-0705; the heating screen printing coating 22 is a thick film heating element made of rare earth elements. This heating element is composed of rare earth elements (such as cerium, lanthanum, praseodymium, etc.) and conductive powders (such as zirconia, niobium oxide, etc.). Rare earth elements have excellent electromagnetic properties and stable chemical properties, while conductive powders provide good electrical conductivity and thermal stability.
[0022] In this structure, the heating plate adopts a plate-like structure, which increases the contact surface and can be adapted to the cross-flow fan with a broad and uniform air flow. The mesh cover fixing plate 4 serves as a base for facilitating the coating of each layer on it. The mesh cover fixing plate 4 is provided with air ducts for the air flow to pass through. The mesh cover fixing plate 4 cooperates with the fan to make the air flow pass through the air ducts, so as to form a hot air flow and blow it out. The heating screen printing coating 22 serves as the heating part, and is equipped with a thermostat 6 to monitor the heating temperature in real time to control the on-off of the current of the conductive heating layer 2 through the wiring board 5. Conventional heating wires are usually made of metals, such as nickel-chromium alloys. This material has a high resistivity and can generate a large amount of heat when electrified. However, due to the relatively thin size of the heating wire, the heat is easily concentrated in a small area when the heating wire is heated. Therefore, it is not suitable for large-area uniform heating and is more suitable for small-area local heating. This heating plate solution adopts a rare-earth heating method, using rare-earth elements to form a conductive heating layer. These elements have good thermal stability and a high melting point, can work stably in a high-temperature environment, and can withstand repeated thermal cycles without significant degradation. In addition, the design of the rare-earth heating plate can make the heat distribution uniform and improve the heating efficiency. The structural design of the rare-earth heating plate enables them to cover a large area and is suitable for large-area uniform heating.
