Description

Technical Field

[0001] The utility model belongs to the field of new energy vehicle battery management, and specifically relates to a novel heating radiator for a carriage. Background Art

[0002] Buses are an important means of transportation in my country, and interior temperature is a key factor affecting passenger comfort. To maintain a comfortable temperature in bus cabins even in cold weather, in addition to improving the insulation (cold-proofing) of the bus body, it is also necessary to install heat-generating heating devices to compensate for heat loss within the bus.

[0003] The working principle of the heating device is to connect to the engine or heater, connect the hot water heated by the engine or heater to the radiator core, and use the fan to bring the heated hot air out of the radiator, thereby quickly achieving a heating effect in the car. The existing practices are usually:

[0004] First, the domestic market currently generally uses wall-mounted radiators for heating. This type of radiator blows hot air into the car through a single surface. Usually, the heating effect is good for seats facing the radiator, but poor for seats not facing the radiator. There is also the problem of poor heating uniformity.

[0005] Second, existing products use aluminum profile shells. In order to ensure uniformity and coordination with the color of the car body, they usually need to be processed by powder spraying, anodizing and other processing methods, which have high requirements on the processing and transportation process and low yield.

[0006] Therefore, traditional heating radiators use a one-way blowing method, which has problems such as limited layout and uneven heating. They also require secondary surface treatment and have a low yield rate.

[0007] CN211969116U discloses a passenger car and a vehicle heating and heat dissipation device, comprising a carriage and a vehicle heating and heat dissipation device, wherein the vehicle heating and heat dissipation device comprises a radiator, a fan, and a heat dissipation shell. The radiator is used to supply heat to the carriage, and the fan blows the heat emitted by the radiator into the carriage through airflow to achieve a heating effect. The heat dissipation shell comprises a carriage-fixed portion fixed to the carriage and a cylindrical air outlet portion. The air outlet portion has multiple air outlets distributed on the circumferential surface. Air flows out from the air outlets in multiple directions to dissipate heat and blow air around the heat dissipation shell. The patent also discloses a heat dissipation box structure, but in this structure, the motor is suspended, which causes excessive vibration. Utility Model Content
