Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, specifically a water-cooled booster air cooler. Background Technology

[0002] A water-cooled turbocharged air cooler is a device that lowers the intake air temperature by exchanging heat between the coolant (usually engine coolant) and the high-temperature, pressurized air. It is a core component of the intake system of a turbocharged engine. Its working principle is as follows: the high-temperature compressed air after turbocharging flows through the internal channels of the cooler, exchanging heat with the externally circulating low-temperature coolant. This lowers the intake air temperature, thereby increasing the intake air density, increasing the oxygen content, and ultimately improving engine power while reducing emissions.

[0003] When existing water-cooled booster air coolers are in operation, oil mist, water vapor and particulate impurities carried by the booster air can easily enter the heat exchange tube mechanism, adhere to the surface of the heat exchange tube to form dirt and oxide layer, hinder heat exchange and reduce cooling efficiency. To address this, we propose a water-cooled booster air cooler. Utility Model Content

[0004] The purpose of this invention is to provide a water-cooled booster air cooler to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-cooled booster air cooler, comprising a cooler shell and a heat exchange tube mechanism disposed inside the cooler shell, wherein two air inlet pipes are embedded in the front side wall of the cooler shell, and two air outlet pipes are embedded in the rear side wall of the cooler shell, and the two connecting ends of the heat exchange tube mechanism are respectively provided with a liquid inlet pipe and a liquid outlet pipe;

[0006] A liquid storage tank is installed at the lower end of the outer wall of the front end of the cooler shell. A pump body is fixedly connected to both sides of the liquid storage tank. A one-way valve pipe is fixedly connected to the output end of the pump body and extends to the bottom of the air inlet pipe. Several condensation protrusions are provided at the inner and outer angles of the bend of the air inlet pipe. A liquid accumulation groove is opened at the bottom of the inner wall of the air inlet pipe.

[0007] Preferably, mounting plates are fixedly connected to the lower ends of both sides of the cooler housing.

[0008] Preferably, the air intake pipes are all arranged in a 90-degree bend.

[0009] Preferably, the number of condensing bosses located at the outer end of the elbow is greater than the number of condensing bosses located at the inner end of the elbow.

[0010] Preferably, the condensation boss is made of one of aluminum alloy, stainless steel, and copper alloy.

[0011] Preferably, the liquid accumulation trough is located at the bottom of the curved section, and the edge of the liquid accumulation trough is arc-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a condensing protrusion at the 90-degree bend of the intake pipe, the thermal conductivity of the protrusion is used to condense the oil mist and water vapor in the pressurized air. The number of protrusions at the outer end is greater, which matches the distribution of centrifugal force of the airflow, improves the impurity interception efficiency, and effectively reduces the adhesion and accumulation of oxide layer and various impurities on the surface of the heat exchange tube in the heat exchange tube mechanism. The liquid accumulation groove with the arc edge is located at the bottom of the bend section, which facilitates the collection of liquid accumulation. The liquid storage tank, in conjunction with the pump body and the one-way valve pipe, can actively discharge the liquid accumulation and avoid backflow. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 The present invention provides the following technical solution:

[0019] Example 1: A water-cooled booster air cooler includes a cooler housing 1 and a heat exchange tube mechanism 2 disposed inside the cooler housing 1. Two air inlet pipes 11 are embedded in the front side wall of the cooler housing 1, and two air outlet pipes 12 are embedded in the rear side wall of the cooler housing 1. The two connecting ends of the heat exchange tube mechanism 2 are respectively provided with a liquid inlet pipe 21 and a liquid outlet pipe 22. Mounting plates 13 are fixedly connected to the lower ends of both sides of the cooler housing 1. The air inlet pipes 11 are all bent at 90 degrees.

[0020] During operation, when high-pressure, high-temperature gas enters the cooler housing 1, the pressurized air comes into full contact with the heat exchange components of the heat exchange tube mechanism 2. At this time, the low-temperature coolant flows into the heat exchange tube through the inlet pipe 21 and exchanges heat with the high-temperature air outside the tube during its circulation. The heat in the pressurized air is absorbed by the coolant, and its temperature drops significantly. The coolant, having absorbed heat, is discharged through the outlet pipe 22, achieving heat dissipation circulation. The cooled, low-temperature, high-density air is then discharged from the two outlet pipes 12 at the rear end and enters the engine intake system to improve combustion efficiency. Throughout the process, the mounting plates 13 on both sides of the cooler housing 1 ensure the stable fixation of the equipment.

[0021] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a liquid storage tank 3 is installed at the lower end of the outer wall of the front end of the cooler shell 1; a pump body 31 is fixedly connected to both sides of the liquid storage tank 3; a one-way valve pipe 32 is fixedly connected to the output end of the pump body 31 and extends to the bottom end of the inner end of the air inlet pipe 11; several condensing protrusions 14 are provided at the inner and outer angles of the bend of the air inlet pipe 11; a liquid accumulation groove 101 is opened at the bottom end of the inner wall of the air inlet pipe 11; the number of condensing protrusions 14 located at the outer end of the bend is greater than the number of condensing protrusions 14 located at the inner end of the bend; the condensing protrusions 14 are made of one of aluminum alloy, stainless steel and copper alloy; the liquid accumulation groove 101 is located at the bottom end of the bend, and the edge of the liquid accumulation groove 101 is arc-shaped.

[0022] During use, when high-temperature pressurized air flows in through the 90-degree bend in the intake pipe 11, most impurities (oil mist, particles) accumulate at the outer end of the bend due to centrifugal force. At this time, the more numerous condensing protrusions 14 (made of heat-conducting materials such as aluminum alloy and stainless steel) at the outer end utilize their own temperature difference with the airflow to quickly condense the oil mist into a liquid film, while the smaller number of condensing protrusions 14 on the inner side help to intercept residual impurities.

[0023] Due to centrifugal force, the liquid film on the smooth condensation boss 14 is intercepted and slides down the pipe wall to the bottom liquid collection tank 101 (the arc edge avoids the accumulation of impurities). The pump body 31 in the liquid storage tank 3 draws the impurities in the liquid collection tank 101 to the liquid storage tank 3 for collection through the one-way valve pipe 32 (to prevent backflow of airflow), thus preventing the liquid from flowing back into the airflow. The air inlet pipe 11 also needs to be maintained regularly.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
