Abstract
The utility model relates to a cooler used for cooling hydraulic oil in a cooling hydraulic machinery, comprising a hull with a water pipe, an upper end head with an inlet pipe, an outlet pipe and a baffle, a bottom end head with a baffle, a hole plate which is provided with a pipe bundle at two ports of the hull, a core pipe that is inserted into a tube of the pipe bundle, a top flat head which is provided with a hydraulic oil inlet-and-outlet pipe, a baffle and a mounting hole of the core pipe, a bottom flat head which is provided with a baffle and a mounting hole of the core pipe, a sealing ring on the surface of the connecting ends and a connecting bolt. During the process of cooling, the hydraulic oil is positioned in the ring passage from the outer periphery of the core pipe to the pipe bundle and is cooled by the cooling water from two directions, so that the temperature differential between the inlet and the outlet of the hydraulic is great. After being tested, if the proportion of the water flow and the oil flow is 1:1, the temperature of the hydraulic oil can be lowered by 25 DEG C at a time after cooling; if the proportion of the water flow and the oil flow is 1:2, the temperature can be lowered by 13 DEG C at a time after cooling. The utility model has large heat transfer area and good cooling effect.
Description
Technical field
The utility model relates to a kind of heat exchanger, relates in particular to a kind of cooler of pressing oil with cooling liquid machinery.
Background technique
In the prior art, be used to cool off the cooler of hydraulic machinery hydraulic oil, be by housing, the deflection plate of housing penetrates the tube bank in the baffle hole, the tube bank fixed plate of tube bank two ends, hydraulic oil inlet tube that communicates with housing and hydraulic oil outer pipe on the housing, flange on the housing two ends, the end socket of housing two ends, wherein the end socket of an end has dividing plate and the cooling water intake pipe and the cooling water outlet pipe that communicate with the end socket inner chamber constitute.More than constitute and be tubular cooler.
Since the heat exchange of water, oil be carry out with the oil that enters shell side by the water that enters straight tube tube bank, it just carries out heat exchange by straight tube tube wall and the oil that enters shell side, makes oily temperature drop low, and water temperature is raise.Its heat exchange area is restricted, and the out temperature difference of hydraulic oil is little, so heat exchange effect is poor.With heat exchange area is that 4 square metres cooler is an example, and when the inlet temperature of hydraulic oil was 60 ℃, water, oily flow-rate ratio were 1: 1 o'clock, were 50 ℃ through cooled oily temperature, and the temperature difference only is 10 ℃, and not only cooling effect is poor for it, and the consumption of cooling water is big.The purpose of this utility model provides a kind of under the identical situation of cooler volume, makes its heat exchange area increase, good cooling results, the cooler that is used to reduce hydraulic fluid temperature that water consumption is little.
Summary of the invention
Be used to cool off the cooler of hydraulic machinery hydraulic oil, it comprises the housing that constitutes cooler, the lower end mouth of cooler casing and upper end-hole have the orifice plate with the integrant installation tube bank of housing, become overall structure through welding with orifice plate in the two ends load hole plate hole of tube bank, intake pipe on the housing and outlet pipe, the upper end end socket of cooler and lower end end socket, on the end socket of upper end intake pipe and the outlet pipe that communicates with upper end end socket inner chamber arranged, the deflection plate of the change flow of cooling water direction in the end socket of upper end, the deflection plate of the change flow of cooling water direction in the end socket of lower end, be characterized in: with the deflection plate of the flow of cooling water direction that changes on the upper and lower port orifice plate of upper end-hole orifice plate of the integrant installation of housing tube bank, be inserted with the core pipe of the water-cooling tube that constitutes tube bank in the socket of two-port section by welding and upper end-hole orifice plate and the integrant tube bank of lower end mouth orifice plate, the lower end mouth orifice plate of housing is to the lower end flat-top end socket that has cooling water tube core pipe mounting hole is arranged between the end socket of lower end, have in the flat-top end socket of lower end with the flat-top end socket in the flow deflection plate of direction of integrant change hydraulic oil is arranged, the core pipe lower end of water-cooling tube is packed into and is constituted integral body through welding and following flat-top end socket in the mounting hole of following flat-top end socket, following flat-top end socket between the orifice plate of housing lower end and following flat-top end socket between the end socket of lower end, seal ring is arranged.Following flat-top end socket is mounted to integral body by the bolt hole on its peripheral bolt hole, the lower end end socket periphery, the bolt hole on the housing lower end mouth orifice plate periphery by bolt.The upper end-hole orifice plate of housing is to last flat-top end socket is arranged between the end socket of upper end, be distributed with the mounting hole of cooling water tube core pipe on the last flat-top end socket, the deflection plate of the mobile direction of the hydraulic oil that changes in the last flat-top end socket, the core pipe upper tip of water-cooling tube is packed into and is constituted in the mounting hole of going up the flat-top end socket wholely through welding and last flat-top end socket, and the inlet tube and the outer pipe of the hydraulic oil that communicates with last flat-top end socket inner chamber are arranged on the wall of last flat-top end socket.Between last flat-top end socket and the upper end end socket and between the orifice plate suitable for reading of housing seal ring is arranged.Last flat-top end socket is by the bolt hole of periphery, and the bolt hole of the bolt hole of upper end end socket periphery, housing upper end-hole orifice plate periphery connects into integral body by bolt.
The cooler that is used to cool off hydraulic machinery hydraulic oil of the present invention, the cooling water that is used to cool off hydraulic oil enters cooler by two-way, one road intake pipe from the housing enters the housing inner chamber, under the effect of the deflection plate on deflection plate on the last flat-top end socket and the lower end flat-top end socket, finish four strokes, flow out via the outlet pipe on the housing.Another road enters cooler from the intake pipe on the end socket of upper end, enters under the deflection plate effect in deflection plate in the end socket of upper end and the lower end end socket to constitute tube bank and core pipe, finishes four strokes and is flowed out by the outlet pipe on the end socket of upper end.Need the hydraulic oil of cooling to enter cooler by the inlet tube on the last flat-top end socket wall, in last flat-top end socket in deflection plate and the following flat-top end socket under the effect of deflection plate, hydraulic oil enters the peripheral channel of core pipe to tube bank, and behind four strokes of flowing through, the oil outlet tube from last flat-top end socket wall flows out.The hydraulic oil that enters in the cooler carries out two-way heat exchange with the cooling water that enters the cooling water in the housing and enter in the core pipe, be that hydraulic oil is subjected to cooling of two-way cooling water, its stroke is long, and the flow time of liquid in cooler is long, heat exchange area is big, good cooling results.The out temperature difference of hydraulic oil is big, using water wisely.After testing, when water oil flow-rate ratio was 1: 1, once lowering the temperature after the hydraulic oil cooling to reach 25 ℃, and when the ratio of water oil was 1: 2, hydraulic oil is once lowered the temperature after cooling can reach 13 ℃,
