Description

Technical Field

[0001] The utility model belongs to the field of new energy cooling modules, and in particular relates to an air outlet regulating device for an air inlet bin of a high-temperature environment bin of a new energy cooling module. Background Art

[0002] In the existing technology, new energy vehicles (such as hydrogen fuel cell vehicles) need to use cooling modules to dissipate heat during operation. The radiator in the cooling module determines the heat dissipation performance. In order to measure the heat dissipation performance of the radiator assembly under different operating conditions, automotive standards require testing the heat dissipation performance of the radiator when the ambient temperature reaches 40℃~45℃. By creating a high-temperature environmental chamber to provide the radiator with an ambient temperature of 40℃~45℃, the radiator is placed in the air inlet chamber of the high-temperature environmental chamber. The air inlet chamber can return the hot air from the radiator's outlet side to the air inlet chamber through a return fan. The problem is that in order to adjust the amount of cold air entering the air inlet chamber, there is an urgent need for an air outlet adjustment device for the air inlet chamber. Utility Model Content

[0003] The purpose of this utility model is to provide an air inlet adjustment device for the air inlet bin of a high-temperature environment bin of a new energy cooling module, which can adjust the amount of cold air entering the air inlet bin. The air volume of both hot air and cold air can be adjusted to adjust the ambient temperature of the air inlet bin.

[0004] The purpose of the utility model is achieved as follows: an air outlet adjustment device for an air inlet bin of a high-temperature environment bin of a new energy cooling module comprises an air inlet bin, a plurality of openable inspection doors are provided on the side walls of the air inlet bin, each of the inspection doors is hinged to the air inlet bin through at least two door leaves spaced up and down, a plurality of mounting holes are provided on the inspection door, a ventilation screen is filled and fixed in each mounting hole, and a shielding plate that can slide back and forth is provided on the inspection door corresponding to each ventilation screen.

[0005] When the utility model is in operation, the position of the shielding plate can be adjusted by sliding back and forth to block the corresponding ventilation screen, thereby adjusting the number of ventilation screens that can let in cold air and adjusting the amount of cold air entering the air inlet. Compared with the existing technology, the utility model has the following advantages: the amount of cold air entering the air inlet can be adjusted, and the air volume of both hot and cold air can be adjusted to adjust the ambient temperature of the air inlet; and the air inlet can be easily entered for maintenance work by opening the maintenance door.

[0006] As a further improvement of the present invention, at least two inspection doors are provided, and the at least two inspection doors are symmetrically arranged on both sides. Latch pins are installed on the inspection doors, and latch seats are provided on the side walls of the air inlet bin corresponding to the latch pins. The latch pins are inserted into the latch seats to lock the position of the inspection doors.

[0007] As a further improvement to the present invention, the ventilation screens, access door, and shielding plate are all rectangular. A transverse guide rail with a T-shaped cross section is provided on the outside of the access door, corresponding to the upper and lower sides of each ventilation screen. Two T-shaped slots are provided on the underside of the shielding plate, corresponding to the two guide rails. The guide rails fit into the corresponding slots. The shielding plate moves back and forth along the guide rails to adjust the area of ​​the ventilation screens blocked, thereby adjusting the air intake area.

[0008] As a further improvement of the present invention, four rectangular sealing strips are provided on the access door at the periphery of each ventilation screen, which enhance the sealing performance between the shielding plate and the ventilation screen.

[0009] In order to prevent the shielding plate from sliding off the guide rail, both ends of the guide rail are provided with upwardly protruding limit blocks.

The coolant enters the radiator and is then discharged through the heat pipe. The air passes through the air inlet side of the heat dissipation belt on one side of the radiator and is discharged from the air outlet side. The exhaust side of the heat dissipation belt is close to the heat dissipation holes, and the air inlet side of the heat dissipation belt is far away from the heat dissipation holes. The air and coolant exchange heat to complete the heat dissipation. The heat exhaust fan on the radiator body sucks the hot air into the heat recovery bin. The heat recovery bin and the air inlet bin are both rectangular and share a side wall. The return fan sucks the hot air in the heat recovery bin into the air inlet bin, and the cold air enters the air inlet bin through the ventilation screen and mixes with the hot air. The temperature sensor on the front side of the radiator measures the inlet temperature. The temperature sensor and the return fan are connected to the controller. The temperature sensor transmits the inlet temperature signal to the controller. The controller controls the speed of the return fan to adjust the amount of hot air entering the air inlet bin, thereby adjusting the temperature environment of the air inlet bin where the radiator is located to ensure that the temperature on the inlet side of the radiator's heat dissipation belt is 40-45°C.
