This technical problem solves through a kind of heat exchanger, also solves through a kind of air conditioning equipment of car, and solves through a kind of automobile.
But heat exchanger designs required for protection is used for air conditioning equipment of car and has the interior pipe of at least one heat exchanger medium circulation and the outer tube of flexible design, and said outer tube surrounds said interior pipe at least regionally can be by the gap of heat exchanger medium circulation to constitute at least one.
At this, interior pipe and outer tube are connected into the coolant circulation circuit of said air-conditioning equipment like this, make between outer tube and interior pipe can by the flow direction in the gap of heat exchanger medium circulation with flow through in the flow direction of the heat exchanger medium of managing opposite.Therefore this heat exchanger moves according to convective principles.
Pipe also has the pipeline section that at least one favours the outer tube longitudinal extension in said; And therefore the length and/or the direction of pipe in can changing thus can provide a kind of flexible design and heat exchanger that can adapt to the automobile mounting condition of predesignating generally speaking personalizedly.
Said outer tube is just relatively gentle originally and therefore deformable through the outer tube material of using relative flexibility, also can extend within the specific limits in case of necessity, and for pipe in said can also as before use relative stiffness and tube material inflexibility.
Yet through at least partly favouring the pipeline section of said outer tube longitudinal extension, said interior pipe can carry out the change of length and/or direction on the whole relatively simply through changing its geometric modeling.
If for example along the pipe longitudinal 2 observation; Pipe portion section is alternately extended along reverse each other oblique line in a plurality of; Thereby observe in the vertical and produced jagged trend; Then can make by stretching from external action said in pipe change length, wherein, the pipeline section that favours longitudinal extension only slight modification direction.
