Abstract
The utility model belongs to an engine oil (lubricating oil) cooling device, particularly an engine oil cooler which is suitable for an internal-combustion engine. The cooler is composed of a casing, a water inlet chamber, a water outlet chamber, a pipe plate, an oil inlet, an oil outlet, a baffle plate and a heat exchange element. The heat exchange element adopts a cold rolling fin pipe, and is connected with the pipe plate in the mode of expansion connection; the baffle plate adopts a labyrinth type. The cooler has good cooling effect, durable heat exchange, strong corrosion resistance, easy scaling, small size, light weight and high reliability.
Description
The utility model belongs to machine oil (lubricant oil) cooling equipment, particularly a kind of machine oil cooler that is applicable to various internal-combustion engines.
The machine oil cooler of using at present is light pipe formula or light pipe nest plate type, and cooling effect is relatively poor, and volume is big.Because the heat-transfer coefficient of light pipe is low,, and, make cooling effect of cooler poor because the thermal contact resistance between nest plate and the pipe is big so the volume of this cooler and weight are bigger.
The purpose of this utility model is to provide the machine oil cooler that a kind of volume is little, in light weight, corrosion-resistant, reliability is high, heat exchange is lasting.
The utility model is realized in the following manner.
Machine oil cooler is made up of housing, intake chamber, water-supplying chamber, tube sheet, oil inlet and outlet, deflection plate, heat-exchanging element, it is characterized in that heat-exchanging element adopts cold-rolled fined tube, fin height is 3-10mm, with distance is 1.5-3mm, cold-rolled fined tube adopts expanding joint process to connect with tube sheet, and the shape of deflection plate adopts the mazy type circle that can effectively prevent escape of liquid to lack shape.
The utility model is because employing cold-rolled fined tube and mazy type circle lack the shape deflection plate, thereby good cooling results, and heat exchange is lasting, corrosion-resistant, easy scaling, and volume is little, and is in light weight, the reliability height.
Description of drawings: Fig. 1 is the structural representation of the utility model (single process), and Fig. 2 is the schematic representation of the utility model deflection plate.1 is that housing, 2 is that intake chamber, 3 is that water-supplying chamber, 4 is that tube sheet, 5 is that oil inlet and outlet, 6 is that deflection plate, 7 is a heat-exchanging element among the figure.
Below in conjunction with description of drawings implementation process of the present utility model:
Machine oil enters cooler shell-side transversal flow outside heat-exchanging element 7, and comes and goes mobile 6 of deflection plates.It is inner vertically mobile that cooling water enters heat-exchanging element 7 from intake chamber 2, and flow out coolers through water-supplying chamber 3.By the augmentation of heat transfer effect of cold-rolled fined tube, absorb the heat of machine oil, the temperature of machine oil is reduced, reach cooling purpose.Because the seal action of mazy type deflection plate, machine oil can only guarantee the heat exchange effect in the shell-side lateral flow.
