Abstract

The invention discloses a parallel flow air-cooling oil cooler, and belongs to the field of heat exchangers. The parallel flow air-cooling oil cooler consists of an air duct, an oil inlet general pipe, a bypass flow oil inlet branch pipe, a parallel flow pipe, a fan, a bypass flow oil return branch pipe, a heat transfer fin and an oil return general pipe. The parallel flow air-cooling oil cooler cools hot oil sent from the oil inlet general pipe to the required temperature by utilizing cold air blown by the fan; and because the used cooling medium is air, the heat transfer fin fixed on the wall surface of the parallel flow pipe intensifies convection and heat exchange greatly. The parallel flow air-cooling oil cooler has the advantages that volume is small, installation and use are convenient, and energy and material are saved. The parallel flow air-cooling oil cooler is suitably used in machine tools, vehicles and cranes.

Description

The air-cooled oil cooler of concurrent flow

Technical field:

Title of the present invention is the air-cooled oil cooler of concurrent flow, belongs to field of heat exchangers.It is made up of air channel, oil-feed house steward, shunting oil-feed arm, concurrent flow pipe, fan, shunting oil returning branch pipe, thermofin and oil return house steward.The cold wind that the air-cooled oil cooler of concurrent flow fan capable of using blows out will be cooled to required temperature from the deep fat that the oil-feed house steward sends into.

Background technology:

Mostly the oil cooler that uses is to adopt water to cool off at present; It makes shell-and-tube heat exchanger usually, and the array heat-transfer pipe places heat exchanger shell, logical cooling medium water in the heat-transfer pipe; Be exactly the passage of oil between heat-transfer pipe and housing, shell-side is separated into the runner of oil by some deflection plates.When oil cooler is worked, will pass to a large amount of cooling water (about 1: 1.8), thereby alternate source will be arranged, and the water pump operation power consumption is also many.

Summary of the invention:

For remedying the deficiency of existing above-mentioned technology, the present invention can provide a kind of volume little, in light weight, adopt aluminium matter, easy for operation and the air-cooled oil cooler of concurrent flow that need not water.For reaching this purpose, the air-cooled oil cooler of concurrent flow should be made up of air channel (1), oil-feed house steward (2), shunting oil-feed arm (3), concurrent flow pipe (4), fan (5), shunting oil returning branch pipe (6), thermofin (7) and oil return house steward (8).Oil-feed house steward (2) and oil return house steward (8) place on the end face of air channel (1) abreast, and 1～10 shunting oil-feed arm (3) and oil-feed house steward's (2) the bottom end face that vertically passes air channel (1) after fixed that links inserts in the air channel (1); 1～10 shunting oil returning branch pipe (6) of and parallel pairing identical with shunting oil-feed arm (3) quantity and oil return house steward's (8) the bottom end face that vertically passes air channel (1) after fixed that links inserts in the air channel (1).This each 2～50 concurrent flow pipes (4) all are housed on to shunt pipe, it is fixed that an end of each concurrent flow pipe (4) and shunting oil-feed arm (3) link, and the other end of this concurrent flow pipe (4) links fixed with shunting oil returning branch pipe (6); A concurrent flow pipe (4) that is installed on every pair of shunt pipe all maintains uniform distances, and thermofin (7) all is housed between per two concurrent flow pipes (4), is consolidated adjacent two concurrent flow pipes (4); Oil-feed house steward (2), shunting oil-feed arm (3), concurrent flow pipe (4), shunting oil returning branch pipe (6), thermofin (7) all place in the air channel (1); Fan (5) also places in the air channel (1), and the fan blade of fan (5) is towards shunting oil-feed arm (3), concurrent flow pipe (4), shunting oil returning branch pipe (6), the formed heat exchanger of thermofin (7).

Description of drawings:

Fig. 1. be the air-cooled oil cooler vertical view of concurrent flow,

Fig. 2 is that the A of Fig. 1 is to view.

Wherein: the 1--air channel; 2--oil-feed house steward; 3--shunting oil-feed arm 4--concurrent flow pipe; 5--fan, 6--shunt oil returning branch pipe; The 7--thermofin; 8--oil return house steward.

Oil-feed house steward (2) and oil return house steward (8) place on the end face of air channel (1) abreast, and 1～10 shunting oil-feed arm (3) and oil-feed house steward's (2) the bottom end face that vertically passes air channel (1) after fixed that links inserts in the air channel (1); 1～10 shunting oil returning branch pipe (6) also inserts in the air channel (1) with oil return house steward's (8) the bottom end face that vertically passes air channel (1) after fixed that links.Not only quantity is identical and pairing and parallel for shunting oil-feed arm (3) and shunting oil returning branch pipe (6); Each is to all being equipped with 2～50 concurrent flow pipes (4) on the shunt pipe, an end of each concurrent flow pipe (4) and shunting oil-feed arm (3) link fixed, and the other end of concurrent flow pipe (4) links fixed with shunting oil returning branch pipe (6); Thermofin (7) all is housed between per two concurrent flow pipes (4), is consolidated two concurrent flow pipes (4); Oil-feed house steward (2), shunting oil-feed arm (3), concurrent flow pipe (4), shunting oil returning branch pipe (6), thermofin (7) all place in the air channel (1); Fan (5) also places in the air channel (1), and the fan blade of fan (5) is towards shunting oil-feed arm (3), concurrent flow pipe (4), shunting oil returning branch pipe (6), the formed heat exchanger of thermofin (7).

Case study on implementation:

Fig. 1 also is the air-cooled oil cooler vertical view of the concurrent flow of the Changjiang river derrick car.Per hour the 2000kg temperature is that 60 ℃ deep fat flows into from oil-feed house steward's (2) port and flows to 3 shunting oil-feed arms (3) equably respectively.Each split inlet manifold (3) evenly opened 21 section 2.5 × 25mm holes 21 parallel flow tube (4) Plug one end of each branch opening up China Unicom and consolidation, and the other end into the shunt inlet manifold (3) uniformly paired opened 21 2.5 × 25mm section of the shunt branch oil return pipe (6) opening up the intercom and consolidation.Be the enhance heat transfer ability, the z shape thermofin (7) that aluminium strip wide with 25mm, thick 0.5mm makes is cemented between adjacent two groups of concurrent flow pipes (4).The concurrent flow pipe (4) of every section 2.5 * 25mm is divided into 6 of the runners of 2 * 4mm again, and it had not only increased the intensity of concurrent flow pipe (4) but also had strengthened the heat transfer of oily side.Power is that fan (5) air output of 30w is 2200m³/ h, pressure 60Pa passes the heat-transfer surface of three layers of concurrent flow pipe (4) and thermofin (7) formation with the speed of 12m/s, and per hour 2000kg/h oil is reduced to below 50 ℃ from 60 ℃.
