| description | The invention relates to a ventilation pipe and a manufacturing method of the ventilation pipe. The ventilation pipe comprises an inner pipe and an outer pipe; the outer pipe is arranged on the outer side wall of the inner pipe in a sleeving manner; the inlet end of the outer pipe is connected to the outer side wall of one end of the inner pipe; the outlet end of the outer pipe is connected to the outer side wall of the other end of the inner pipe; a first cooling liquid channel is formed between the inner side wall of the outer pipe and the outer side wall of the inner pipe; a cooling liquid inlet is formed in the inlet end of the outer pipe, and is communicated with the first cooling liquid channel; and a cooling liquid outlet is formed in the outlet end of the outer pipe, and is communicated with the first cooling liquid channel, and therefore it can be effectively prevented that blow-by in the ventilation pipe ices under the low temperature condition, and the cost of the ventilation pipe is made low.
