【Abstract】:
The present invention relates to a tubular heat exchanger, comprising a first heat dissipation tube and a second heat dissipation tube, wherein a pipe to be cooled is helically wound around an outer wall of the second heat dissipation tube, the first heat dissipation tube surrounds the pipe to be cooled, first and second sealing rings made of plastic material are provided at both ends of the first and second heat dissipation tubes, and first and second conduits are inserted from outside into the first and second sealing rings, the first and second conduits extend to the first and second heat dissipation tubes to form interchangeable heat transfer medium inlets or outlets; in use, heat transfer medium flows through the second heat dissipation tube and between the first heat dissipation tube and the pipe to be cooled. The tubular heat exchanger of the present invention has a simple structure, high heat exchange efficiency, and can meet different cooling requirements.
【Main Claim】:
A tubular heat exchanger, characterized in that: it comprises a first heat dissipation tube and a second heat dissipation tube, a pipe to be cooled is helically wound around an outer wall of the second heat dissipation tube, the first heat dissipation tube surrounds the pipe to be cooled, first sealing rings made of plastic material are provided at both ends of the first heat dissipation tube and first conduits are inserted from outside into the first sealing rings, the first conduits extend to the first heat dissipation tube to form interchangeable heat transfer medium inlets or outlets, similarly, second sealing rings made of plastic material are provided at both ends of the second heat dissipation tube and second conduits are inserted from outside into the second sealing rings, the second conduits extend to the second heat dissipation tube to also form interchangeable heat transfer medium inlets or outlets; in use, heat transfer medium flows through the second heat dissipation tube and between the first heat dissipation tube and the pipe to be cooled.
