Problems solved by technology
[0002] At present, in the plate-fin heat exchangers of loaders and air compressors, when the oil inside the plate-fin heat exchanger has a high viscosity at low temperature and the pressure difference exceeds a certain limit, it is easy to cause the core to burst and cause the plate The finned heat exchanger is damaged and leaks oil and fails
At the same time, during normal operation, the system may experience instantaneous pulse high pressure, which will cause the core to burst and cause the plate-fin heat exchanger to be damaged, leak oil and fail
[0003] It can be seen that in the prior art, there is no plate-fin heat exchanger capable of both low-temperature overload protection and instantaneous high-voltage overload protection, and its reliability is poor and its service life is short.

The invention relates to a plate-fin heat exchanger with a pressure-temperature control valve. The heat exchanger comprises a core body, a first end enclosure, a second end enclosure and a by-pass pipe, wherein the first end enclosure, the core body and the second end enclosure are connected sequentially; the first end enclosure is provided with an oil inlet; the second end enclosure is provided with an oil outlet; and the first end enclosure and the by-pass pipe are communicated through the pressure-temperature control valve. The plate-fin heat exchanger provided by the invention simultaneously has the capabilities of low-temperature overloading protection and instant high-pressure overloading protection, and is good in reliability and long in service life.
Description
technical field [0001] The invention relates to oil cooling equipment used in loaders, air compressors, etc., in particular to a plate-fin heat exchanger with a pressure-temperature control valve. Background technique [0002] At present, in the plate-fin heat exchangers of loaders and air compressors, when the oil inside the plate-fin heat exchanger has a high viscosity at low temperature and the pressure difference exceeds a certain limit, it is easy to cause the core to burst and cause the plate The finned heat exchanger is damaged and leaks oil and fails. At the same time, during normal operation, the system may experience instantaneous pulse high pressure, causing the core to swell and crack, causing damage to the plate-fin heat exchanger, oil leakage and failure. [0003] It can be seen that in the prior art, there is no plate-fin heat exchanger capable of both low-temperature overload protection and instantaneous high-voltage overload protection, and its reliability ...
