Radiator protecting device

Abstract

The invention relates to a radiator protecting device which comprises a lateral plate, a water chamber, a radiator core water pipe and radiating fins. A protecting device is a retaining strip fixedly arranged on the lateral plate through a bolt. The radiator protecting device is simple in structure and convenient to use. A core protecting device retaining strip is added between a main fin at two ends of a radiator core body and a first radiating fin, and an exposed water pipe is protected from being hit by foreign matters. When a water radiator works under severe working conditions, the foreign matters such as raised sand are blown to the radiator core body by a diesel engine, an upper end portion hits on the radiating fins, a lower end portion hits on the retaining strip, and possibility that the water pipe is damaged is effectively reduced. At present, the device is used in massive mode in featured radiators of a certain large-scale project engineering machinery company in our country. After one-year implementation of the device, fault rate in a three-guarantee period is dropped from original 1.3% to 0.6%, and a designing purpose is achieved.

Description

technical field [0001] The invention relates to an improvement of a water radiator of an internal combustion engine of construction machinery, in particular to a radiator core protection device. Background technique [0002] During the production process of water radiators for construction machinery internal combustion engines, due to the limitations of the equipment and the needs of the process, a certain gap must be maintained between the main sheet at both ends of the core and the first cooling sheet. This gap is usually about 10mm. Part of the heat pipe is directly exposed. [0003] When the internal combustion engine water radiator is used in harsh working conditions such as construction machinery, foreign matter such as sand particles raised are blown to the radiator core by the diesel engine fan. Since the water pipe in the middle part of the radiator core is surrounded by cooling fins, the raised sand particles cannot directly hit the water pipe, which will not caus...

AI Technical Summary

Problems solved by technology

The exposed water pipes between the main sheet at both ends of the core and the first heat sink are prone to leakage after being hit by sand particles
