Embodiment Construction

[0026] Please refer to figure 1 As shown, it is the shape of the diamond-shaped mesh electric heating air duct device along the direction of air flow. The width of the metal triangular wave heating belt 5 moves along the direction of air flow. When the mesh electric heating air duct is installed, the airflow flow resistance is generated, and the disturbance to the uniform flow field is reduced at the same time. The width of the metal triangular wave heating belt 5 can be adjusted. The width of the metal triangular wave heating belt 5 can be adjusted according to the heating power design. It can also be designed to adjust the flow direction along the air flow. The diamond-shaped circulation area formed by the upper and lower metal triangle wave heating belts can change the circulation heat exchange area. Control heating power.

[0027] The load-bearing structure of the diamond-shaped mesh electric heating air duct device is welded by metal plate materials. It is the supporting...

Abstract

The invention discloses an electric heating device for a large-section air channel uniform flow field. The electric heating device comprises an air channel lined mica plate, air channel bearing metal plates, high-temperature-resistant ceramic isolation fasteners, metal triangular wave heating tapes, heating tape connecting assemblies and a connecting assembly insulating glue wood plate, wherein the metal triangular wave heating tapes are connected and positioned in a rhombus form with upper troughs opposite to lower peaks through the high-temperature-resistant ceramic isolation fasteners; on the heating tape connecting assemblies on the left and right sides, the metal triangular wave heating tapes are electrically connected in series and in parallel through connecting assembly adapting and fixing bolts according to a certain design; a control loop is constructed by an electric power regulator, a temperature controller and a temperature sensor in order to control the heating temperature of the air flow field uniformly and accurately. In the electric heating device for the large-section air channel uniform flow field, the widths of the heating metal tapes can be designed according to heating power along the air flow direction, thereby fulfilling the aim of controlling the heat exchange area and obtaining a high-quality and uniform temperature air flow field.

Description

Technical field: [0001] The invention relates to an electric heating device, in particular to an electric heating device with a uniform flow field in a large cross-section air duct. Background technique: [0002] In the field of heating the flow field of the uniform air flow in the large cross-section air duct, at present, there is no means of heating the flow field with little disturbance, fast, uniform and accurate. With the development of science and technology, it is necessary to heat the uniform air flow field of the large cross-section air duct to facilitate the study of various characteristics of the test device in the uniform air flow field of the large cross-section air duct under different temperature flow fields. Therefore, there is a need for a heating device that can uniformly and accurately heat the air flow field of a large cross-section air duct without destroying the uniformity of the air flow field. Invention content: [0003] The invention provides an a...
