Description

Technical Field

[0001] The present invention relates to the field of radiator equipment, and particularly to a long-wing column type cast iron radiator that is convenient for cleaning. Background Art

[0002] Cast iron radiators have been widely used for a long time. They have a simple structure, are corrosion-resistant, have a long service life, and a low cost. However, they have a large metal consumption, a low pressure-bearing capacity, and heavy labor in manufacturing, installation, and transportation. The commonly used cast iron radiators have two forms: column type and wing type. The wing type radiators are divided into long-wing type and round-wing type. The disadvantage of sand adhesion on the inner wall of the cast iron radiator affects its use and popularization, and the market share has gradually declined. In recent years, manufacturers have carried out technological reforms, greatly improving the pressure-bearing capacity, inner wall smoothness, and appearance of the cast iron radiator. Although the existing cast iron radiators are corrosion-resistant and have a long life, in actual application, the heat dissipation of the cast iron radiator is relatively average, the heat conduction performance is poor when hot water or steam passes through, and the efficiency is low. Moreover, the existing cast iron radiators lack stability during use. Among them, a stable and efficient cast iron radiator with the application number "CN202121971604.2", this utility model of a stable and efficient cast iron radiator is provided with a first water conduit, a second water conduit, a heat conduction plate, and a curved heat dissipation pipe, improving the heat conduction and heat dissipation effect, enhancing the heat exchange efficiency, and reducing the force-induced shaking inside the radiator body during use, improving the stability during use. However, there is still room for improvement in the use of this cast iron radiator: since the radiator is exposed to the outside for a long time, dust in the air easily adheres to its surface. During installation, it is usually close to the wall, making the surface on one side of the wall unable to be cleaned, thus reducing the heat dissipation effect. Moreover, the existing radiator dissipates heat by its own heat radiation, making it impossible to adjust the heat dissipation direction. Summary of the Invention

[0003] The purpose of the present invention is to provide a long-wing column type cast iron radiator that is convenient for cleaning, so as to solve the problems raised in the above background art, that is, since the radiator is exposed to the outside for a long time, dust in the air easily adheres to its surface.

The lifting block moves up and down to drive the cleaning roller brush installed on the surface of the horizontal plate to rotate and move up and down along the cooling fins of the cast iron radiator, so that the cast iron radiator is cleaned by the cleaning roller brush, so as to remove the dust on the surface and ensure the heat dissipation; (2) Through the air supply assembly, a funnel-shaped cover body is installed on the back of the protective cover, and an installation opening is opened in the middle of the funnel-shaped cover body. A mounting plate is installed inside the installation opening, and a protective net is installed on the surface of the mounting plate. The driving motor installed in the middle of the protective net rotates to drive the fan to rotate, and the fan drives the external air flow into the protective cover, so that the air flow is accelerated to take away the heat through the cast iron radiator and form a hot air flow blowing into the room, thereby increasing the heat transfer speed. Feet are installed at the four corners of the installation opening, and the mounting plate is connected to the foot pieces by mounting bolts around the four sides, so that the mounting plate and the funnel-shaped cover body can be detachably connected, which is convenient for the subsequent disassembly and cleaning of the fan.

The louver is hingedly connected to the swing arm through the connecting piece. By turning the adjustment knob, one of the louvers is driven to rotate, thereby driving the other louvers to turn and adjust together through the swing arm, so that the direction of the airflow is changed through the louver, which is convenient for controlling the direction of the airflow and preventing the hot air from blowing in one direction; (4) The protective cover is composed of two parts, namely the first cover body and the second cover body. There are connecting strips at the inner edges of the tops of the first cover body and the second cover body. The first cover body and the second cover body are connected together by fixing screws on the surface of the connecting strip, making the first cover body and the second cover body detachable, which is convenient for installation on the outside of the cast iron radiator. The protective cover can prevent dust from falling on the surface of the cast iron radiator.
