PURPOSE: A heat exchanger for a compressor is provided to be cooling circulation oil and compressed air using one heat exchanger by positioning an extra cooling water circulation pipe along a passage with forming a circulation oil path and a compressed air path separately. CONSTITUTION: A heat exchanger for a compressor comprises an inner pipe(110), an outer pipe(120), a plurality of first cooling water circulation pipes, a plurality of second cooling water circulation pipes(320), and a first switch unit(410). A circulation oil supply port is formed in one side of the inner pipe, a discharge port is formed in the other side of the inner pipe and spaces for circulating oil are formed inside the inner pipe. The outer pipe encloses the inner pipe and the spaces for moving compressed air are formed between an inner wall side of the outer pipe and an outer wall side of the inner pipe. The first cooling water circulation pipe is arranged along a longitudinal direction of the spaces for moving the compressed air. The second cooling water circulation pipe is arranged along the longitudinal direction of the spaces for moving the circulation oil. Cooling water supply port is formed in one side of the first switch unit and a cooling water outlet is formed in the other side of the first switch unit. |
