Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a series-plate convection radiator for railway passenger cars. Background Art

[0002] In my country, passenger cars and passenger trains are the main means of transportation. When the weather is cold, radiators are needed to heat the interior of the carriages to compensate for the lost heat. Most modern vehicles and trains use electricity as the main heating energy source, usually using electric series-type convection radiators or pre-installed electric heating structures for heating. Series-type convection radiators are widely used in railway transportation because of their superior cost performance and relatively easy maintenance.

[0003] After searching, a Chinese patent with publication number CN218583265U discloses a railway passenger car fin-type convection radiator, including a fixing frame, the side walls of the supporting legs at the bottom ends of both sides of the fixing frame are threadedly connected to a grid, the grid is connected and fixed to the side walls of the supporting legs of the fixing frame through a threaded fixing plate, a protective net for protecting passengers and the radiator is arranged inside the grid, a docking plate for splicing with the other half of the grid is fixedly connected to the top of the grid, and threaded fixings are threadedly connected to the center of both sides of the two sets of docking plates.

[0004] The device assists in heat dissipation by adding a protective net, and because it has a large contact area with the outside air, it has an excellent heat dissipation effect, keeping the heat transferred by convection through the protective net body at a relatively low temperature acceptable to the human body, which not only protects passengers from burns but also increases heating efficiency.

[0005] However, the device still has the following problems: a grid and a protective net are arranged on the outside of the multi-tube string-fin radiator, so that the multi-tube string-fin radiator increases the temperature of the protective net through radiation heat transfer, and then improves the heating efficiency through the larger contact area between the protective net and the air. However, in actual use, due to the slow air flow rate in the car, it is not conducive to the string-fin radiator to increase the air temperature in the car. The setting of the protective net further hinders the air flow, making it difficult to effectively improve the heating efficiency. Utility Model Content
