Heat exchanger for crude oil heating

The utility model relates to the technical field of heat exchangers, and provides a heat exchanger for crude oil heating. The heat exchanger comprises a base and a heat exchanger body, wherein the heat exchanger body is obliquely and fixedly installed on the base with the right higher than the left through supporting legs, a coiled pipe is fixedly installed in the heat exchanger body, the liquid inlet end of the coiled pipe is located outside the lower portion of the left end of the heat exchanger body, the liquid outlet end of the coiled pipe is located outside the upper portion of the right end of the heat exchanger body, an oil inlet pipe is fixedly connected to the liquid inlet end of the coiled pipe and an oil outlet pipe is fixedly connected to the liquid outlet end of the coiled pipe; at least two partition plates are fixedly installed in a cavity of the heat exchanger body at intervals from bottom to top, and gaps exist between the right wall of the heat exchanger body and the partition plates. The heat exchanger is reasonable and compact in structure and convenient to use, crude oil can be heated and conveniently conveyed due to the fact that the heat exchanger body, the coiled pipe, the partition plates, a baffle plate and a heating furnace are used in cooperation, the heat exchanger has the advantages of being safe, reliable and capable of controlling temperature easily, operation is facilitated, and heating efficiency is improved.
