Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation equipment for railway vehicles, and in particular to a silent microchannel radiator for railway vehicles. Background Technology

[0002] Microchannels, also known as microchannel heat exchangers, are heat exchangers with channel equivalent diameters ranging from 10 to 1000 μm. These heat exchangers contain dozens of tiny flow channels within flat tubes, which are connected to circular manifolds at both ends. Baffles are installed inside the manifolds to divide the heat exchanger flow channels into several pathways.

[0003] When the radiator is working, the fluid flowing through the microchannels may generate some noise. If the noise is too loud, it may cause discomfort to passengers in the railway vehicle.

[0004] Therefore, we propose a silent microchannel radiator for railway vehicles. Utility Model Content

[0005] The main objective of this invention is to provide a silent microchannel radiator for railway vehicles. It uses a silent fan to remove heat, and sound-insulating pads are installed in the outer shell, the first chamber, and the second chamber. First and second sound-insulating panels are alternately distributed within the first and second chambers, and multiple sound-absorbing holes are provided on the inner wall, effectively achieving both sound insulation and heat dissipation. The dustproof mesh design not only prevents dust from entering and affecting heat dissipation but also provides sound insulation, thereby improving the practicality of the device and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A silent microchannel radiator for railway vehicles includes a housing, one end of which is provided with a connecting frame, and the interior of the connecting frame is provided with a first chamber and a second chamber. Sound insulation pads are fixed to the inner walls of the housing, the first chamber and the second chamber.

[0008] The first chamber and the second chamber are equipped with a first sound insulation board and a second sound insulation board. The first sound insulation board and the second sound insulation board are equipped with multiple sets of equally spaced sound-absorbing holes. The inner walls of the first chamber and the second chamber are fixed with silent fans.

[0009] Furthermore, the top inner wall and bottom inner wall of both the first chamber and the second chamber are provided with mounting grooves for installing the first sound insulation board and the second sound insulation board.

[0010] Furthermore, both the first and second sound insulation panels have protrusions at their top and bottom ends.

[0011] Furthermore, the mounting slots are distributed at equal intervals and staggered, and the size of the mounting slots is adapted to the size of the boss.

[0012] Furthermore, a dustproof net is fixedly installed on the external side of the connecting frame away from the outer shell.

[0013] Furthermore, the inner walls at both ends of the outer shell are provided with support through holes, and microporous heat-conducting sheets are installed inside the support through holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects: heat is carried away by a silent fan, and sound insulation pads are provided in the outer shell, the first chamber and the second chamber. The first sound insulation board and the second sound insulation board are staggered in the first chamber and the second chamber, and multiple sound-absorbing holes are provided in the inner wall, so as to fully realize the sound insulation effect and heat dissipation effect. Through the design of the dustproof net, not only is it prevented from dust entering and affecting the heat dissipation effect, but it also plays a role in sound insulation, thereby improving the practicality of the device.
