Problems solved by technology

[0004] Regardless of whether it is water heating or electric heating, the heat dissipation terminal needs to be installed in the carriage. Due to the limited space in the train carriage, if two sets of heat dissipation equipment are used, it will inevitably occupy a large space in the carriage, seriously affecting the comfort of passenger trains, and cost higher

Embodiment 1

[0022] Such as figure 1 As shown, the water and electricity dual-purpose heating radiator of the present invention includes a heat sink 1 and an electric heating body 2, and the center of the heat sink 1 is a pipeline 3 for passing through a heat-conducting liquid (hot water or steam) for feeding The hot water and steam heated by the surrounding environment flow in the pipeline 3. One end of the pipeline 3 is the inlet of hot water or steam, and the other end is the outlet. The inlet of the pipeline 3 is connected with the boiler at the end of each carriage, and the boiler boils the The water is sent into the pipeline 3 afterward. A plurality of heat dissipation fins 4 are arranged on the periphery of the pipe 3, and the heat dissipation fins 4 are arranged radially on the periphery of the pipe 3, which effectively increases the heat dissipation area of ​​the entire heat dissipation body 1 and improves heat dissipation efficiency. The pipe 3 and the cooling fins 4 are made of...

Embodiment 2

[0030] Such as figure 2 As shown, in this embodiment, after the radiating body 1 and the cover plate 6 are assembled together, the peripheral shape of the cross-section is square as a whole, the accommodating chamber 5 is arranged at the bottom position of the pipeline 3, and the cover plate 6 and the bottom of the tube wall of the radiating body 1 The installation surfaces of the products are all L-shaped, and different installation structures are used according to different installation occasions.

[0031] Other structures are the same as those described in Embodiment 1, and will not be further described in detail here.

Embodiment 3

[0033] Such as image 3 As shown, in this embodiment, after the radiator 1 and the cover plate 6 are assembled together, the peripheral shape of its section is circular as a whole. 1. The installation surfaces at the bottom of the pipe wall are all flat.

Abstract

The invention relates to a heating radiator available in both water heating and electric heating. The heating radiator comprises a radiator body and an electric heating body, wherein a pipeline allowing heat conducting liquid to pass through is arranged at the center of the radiator body, a plurality of cooling fins are arranged on the periphery of the pipeline, a containing cavity is formed in the radiator body, and the electric heating body is mounted in the containing cavity and is fixed on the radiator body through a cover plate. The heating radiator has the advantages of an electric heating system as well as a water heating system, the overall structure is simple, cost is low, the electric heating body is fixed by means of the wall of the pipeline, the cover plate is used for installation and fixation of the electric body as well as heat dissipation, installation and maintenance can be achieved conveniently, occupied space is small, the shape of the heating radiator can be changed freely according to the installation position in a carriage, and universality is high.

Description

technical field [0001] The invention relates to a heating device, in particular to a hydropower dual-purpose heating radiator used on rail vehicles, and belongs to the technical field of rail vehicle heating. Background technique [0002] There is a boiler at one end of the carriages of domestic passenger trains, which uses coal to heat the water in the boiler to provide passengers with train heating in winter. Boiler plumbing costs are low, heating is uniform, and comfort is good, but the train needs to be refueled at the departure station, and during the train, staff are required to add coal, ignite, and remove slag, which not only increases the labor intensity of the staff , Also pollute the environment of train simultaneously, and boiler heating starts and stops slowly. In order to improve this situation, on the current high-speed trains such as EMUs, electric heating is used to provide passengers with train heating in winter. The electric heating device is connected to...
