Problems solved by technology
Although it can reduce the return of cold air flow through the heater core and then blow to each air outlet, thereby increasing the cooling efficiency and reducing the fuel consumption of the vehicle during cooling, it can adjust the outlet air temperature, air volume and linearity, with high control accuracy and improved cooling efficiency , but it is a structure designed for refrigeration, which still cannot solve the problem that the hot runner is too small

Embodiment
[0014] A car air-conditioning damper structure, such as figure 1 with figure 2 As shown, including the main structure of the automobile air-conditioning box, the structure adopts the double damper structure composed of the hot runner damper 4 and the cold runner damper 2, the hot runner damper 4 is located above the cold runner damper 2; when the hot runner damper 4 is closed, the hot runner One of the edges of damper 4 is sealingly fitted on blocking part one 5, and the other edge is sealingly fitted on blocking part two 3; when cold runner damper 2 is closed, one edge of cold runner damper 2 is sealingly fitted on blocking part three 1, the other edge is sealingly fitted on the stop part 2 3. Among them, the hot runner damper 4 is arranged horizontally, the cold runner damper 2 is vertically arranged, and the hot runner damper 4 and the cold runner damper 2 do not interfere with each other; the cold runner damper 2 is located between the blower lower casing 5 and the warm ...

The invention provides an automobile air conditioner air door structure which comprises an automobile air conditioner box main body structure which is provided with a double-air-door structure composed of a hot flow channel air door and a cold flow channel air door, and the hot flow channel air door is located above the cold flow channel air door; when the hot flow channel air door is closed, oneedge of the hot flow channel air door is hermetically matched with a blocking part I, and the other edge of the hot flow channel air door is hermetically matched with a blocking part II; when the coldflow channel air door is closed, one edge of the cold flow channel air door is matched with a blocking part III in a sealed mode, and the other edge of the cold flow channel air door is matched withthe blocking part II in a sealed mode. By adopting the double-air-door structure of the hot flow channel air door and the cold flow channel air door, the sizes of the cold flow channel and the hot flow channel can be optimized in a limited space, the air volume and the heating capacity are promoted to be improved, the linearity of the heating temperature rise of the air conditioning cabinet can beimproved, and the comfort is improved; by the adoption of the automobile air conditioner air door structure, cold air and hot air can be conveniently and flexibly controlled, and the situation that cold air and hot air are mixed in the switching process of the cold air door and the hot air door is basically avoided.
Description
technical field [0001] The invention relates to an automobile air conditioner, in particular to an automobile air conditioner damper structure. Background technique [0002] When the air conditioning box is arranged in the whole vehicle, it is limited by the boundary of the whole vehicle layout, and the space is too small. However, when a temperature damper is used to control the cold and hot runners at the same time, the hot runner will be too small to meet the heating and air volume requirements. . [0003] Document CN206124671U provides an integrated double damper for an automobile air conditioner, including a main cold air door and an auxiliary cold air door, and the auxiliary cold air door is fixedly connected to the main cold air door through a baffle. Although it can reduce the return of cold air flow through the heater core and then blow to each air outlet, thereby increasing the cooling efficiency and reducing the fuel consumption of the vehicle during cooling, it ...
