Description

Technical Field

[0001] The utility model specifically relates to the technical field of high-stability heat exchangers, and specifically is a novel high-stability heat exchanger for bullet trains. Background Technique

[0002] A heat exchanger is an energy-saving device that realizes heat transfer between materials among two or more fluids at different temperatures. It enables heat to be transferred from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the specified index of the process, to meet the needs of process conditions. At the same time, it is also one of the main devices for improving energy utilization efficiency.

[0003] When a bullet train is running, due to the small space inside the bullet train carriage, when it is full, the temperature inside the carriage will rise. In this case, it is necessary to exchange the air inside the carriage to provide a comfortable environment for the passengers inside the carriage. However, currently, traditional central air conditioners are generally used to adjust the temperature inside the bullet train carriage. Due to different personal conditions of the people inside the carriage, in the same environment, some people will feel hot while some people will feel cold. Therefore, when adjusting the temperature inside the carriage, it cannot effectively meet the needs of everyone. Thus, a novel heat exchanger is required;

[0004] Moreover, when the existing traditional heat exchanger is in use, the vibration generated when manually operating the bullet train pneumatically or braking causes the heat exchanger to shake with the bullet train. After long-term use, it may affect the working efficiency of the heat exchanger.

[0005] After retrieval, Chinese Patent Application No. CN202321007953.1 discloses a high-stability bullet train heat exchanger, including a heat exchanger main body and a base for installation. A plurality of installation holes are provided at the edge of the base. A plurality of shock-absorbing strips are installed in the middle of the front end face of the base. A plurality of installation parts are provided at the edge of the heat exchanger main body, and through holes are provided through the installation parts. A plurality of positioning blocks corresponding to the installation parts one by one are provided at the edge of the front end face of the base, and positioning rods are provided on the front end faces of the positioning blocks. Shock-absorbing layers are provided on the outer side walls of the positioning rods. After the positioning rods are inserted into the through holes on the installation parts, they are fixedly connected through fixing nuts;

[0006] When the above-mentioned structure fixes the heat exchanger, by installing the heat exchanger main body on the positioning rods, when the bullet train meets another train, it may shake. In this case, during use, although the heat exchanger main body can achieve a shock-absorbing effect through the shock-absorbing layer and shock-absorbing strips, under the action of inertia, the heat exchanger main body will shake more than the bullet train. As a result, the shock-absorbing layer and shock-absorbing strips cannot effectively shock-absorb the heat exchanger main body up and down, and may even cause the heat exchanger main body to collide with the vehicle body;

[0007] In view of the above situation, we provide a new type of high-stability heat exchanger for bullet trains. In this device, the heat exchanger assembly is fixedly installed on the side plate of the housing with an air inlet through a mounting frame. In this way, the air entering through the air inlet passes through the heat exchanger assembly and is then effectively discharged through the air outlet opened on the front side plate of the housing. Adjacent two heat exchanger assemblies are effectively connected through a liquid inlet and a liquid outlet, so that the effect of coolant circulating cooling can be effectively achieved. A cross beam is arranged between adjacent two heat exchanger assemblies in the housing, and the heat exchanger assemblies are effectively separated and fixed through the cross beam, effectively avoiding the situation that when multiple heat exchanger assemblies are affected by inertia at the same time, damage is caused to the mounting frame or the inside of the housing; greatly improving the stability of the heat exchanger assembly during use.

[0011] Adjacent two heat exchanger assemblies are communicated through a liquid inlet and a liquid outlet; one side of the heat exchanger assembly is fixedly installed with a mounting frame; the mounting frame is fixedly installed with the fixing frame.

[0012] As a further technical solution of the present invention, the heat exchanger assembly and the mounting frame are installed inside the bullet train mounting shell.

[0013] As a further technical solution of the present invention, the bullet train mounting shell includes a housing; the inside of the housing is provided with a cavity; and a cross beam is arranged between adjacent two heat exchanger assemblies inside the cavity.

Through the adjustment of natural wind, the different needs of the people inside the carriage are effectively met;

[0019] In the present utility model, when installing the heat exchanger assembly, the housing is fixedly installed through the mounting frame to realize the fixed support of the heat exchanger assembly.
