Description

Technical Field

[0001] The utility model relates to the technical field of engine coolers, in particular to an engine intercooler. Background Art

[0002] In the modern aviation industry, the performance of aircraft engines is directly related to the fuel efficiency, flight distance and safety of the aircraft. As the flight speed increases and the flight altitude increases, the operating temperature inside the engine rises sharply, which places higher demands on the engine's cooling system. The intercooler, as an important component of the engine cooling system, has the main function of reducing the temperature of the air entering the cylinder during the compression process, thereby improving the engine's power output and efficiency.

[0003] There are many types of intercoolers on the market. Most use serpentine pipes to transport phase-change cooling media to achieve cooling and refrigeration effects. However, these intercoolers generally use a cylinder to directly contain the returning cooling media at the heat dissipation end. The cylinder has a small contact area with the air, which is not conducive to the rapid heat dissipation of the cooling media in the pipe at the heat dissipation end, further affecting the subsequent heat dissipation effect. In view of this, we have proposed an engine intercooler. Utility Model Content

[0004] The purpose of the present utility model is to provide an engine intercooler to solve the defects mentioned in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An engine intercooler comprises a coolant storage cylinder, a delivery pump is provided on one side of the coolant storage cylinder, a water inlet end of the delivery pump is connected to the coolant storage cylinder by a suction pipe, a delivery pipe is fixedly installed on the water outlet end of the delivery pump, a first serpentine tube is fixedly installed on the end of the delivery pipe, an intake pipe is fixedly installed on the end of the first serpentine tube, a cooling cylinder is fixedly installed on the end of the intake pipe, a conical cylinder is fixedly installed on the bottom surface of the cooling cylinder, a liquid outlet pipe is fixedly installed on the bottom end of the conical cylinder, a second serpentine tube is fixedly installed on the end of the liquid outlet pipe, a return pipe is fixedly installed on the end of the second serpentine tube, and a plurality of third radiating fins arranged in a ring with equal intervals are fixedly installed on each horizontal section of the second serpentine tube.

[0007] Preferably, a plurality of first heat sinks arranged in a ring shape and at equal intervals are fixedly mounted on the annular side surface of the coolant storage cylinder, and the first heat sinks are arranged along the height direction of the coolant storage cylinder.

[0008] Preferably, a threaded adding tube connected to the interior of the coolant storage tube is fixedly mounted on the top surface of the coolant storage tube, and the inner diameter of the threaded adding tube is greater than 3 cm.

[0009] Preferably, a threaded cover is threadedly connected to the threaded adding tube, and anti-slip stripes are provided on the annular side surface of the threaded cover.

[0010] Preferably, a plurality of second heat sinks arranged in a ring shape with equal intervals are fixedly mounted on the annular side surface of the cooling cylinder, and the number of the second heat sinks is between 20 and 48.

[0011] Preferably, the terminal tube body of the suction tube is located near the bottom of the coolant storage cylinder, and the terminal tube body of the return tube is located near the top of the coolant storage cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model stores phase-change coolant by setting a coolant storage cylinder, and uses a delivery pump to deliver it. After the phase-change coolant is delivered to the first serpentine tube, the cooling medium in the first serpentine tube performs heat exchange operation on the engine part. When the cooling medium absorbs heat and reaches the boiling point, a phase change occurs, and the gaseous cooling medium is delivered to the second serpentine tube for cooling operation, and cooperates with the third heat sink to dissipate heat, thereby increasing the heat dissipation area and improving the heat dissipation effect. The gaseous cooling medium continues to liquefy and release heat, forming a closed-loop cycle, which greatly improves the cooling efficiency and achieves the effect of efficient circulation heat dissipation.

[0016] 2. The first heat sink and the second heat sink provided in the present invention can continue to dissipate heat to the coolant storage cylinder and the cooling cylinder, making the heat dissipation more comprehensive. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Specifically, an air inlet pipe 30 is fixedly installed at the end of the first serpentine tube 22, a cooling cylinder 3 is fixedly installed at the end of the air inlet pipe 30, a conical cylinder 32 is fixedly installed on the bottom surface of the cooling cylinder 3, a liquid outlet pipe 33 is fixedly installed at the bottom end of the conical cylinder 32, a second serpentine tube 34 is fixedly installed at the end of the liquid outlet pipe 33, a return pipe 35 is fixedly installed at the end of the second serpentine tube 34, and the end of the return pipe 35 is fixedly installed on the coolant storage cylinder 1, and each horizontal section of the second serpentine tube 34 is fixedly installed with a plurality of third heat sinks 341 arranged in a ring with equal intervals, so that the gaseous cooling medium can release heat in the second serpentine tube 34 and the cooling cylinder 3 for heat dissipation operation, and the gaseous cooling medium after heat dissipation can continue to be converted into liquid to realize circulating cooling operation.

[0029] In this embodiment, a plurality of first heat sinks 10 arranged in a ring shape with equal intervals are fixedly installed on the annular side surface of the coolant storage cylinder 1. The first heat sinks 10 are arranged along the height direction of the coolant storage cylinder 1. A plurality of second heat sinks 31 arranged in a ring shape with equal intervals are fixedly installed on the annular side surface of the cooling cylinder 3. The number of the second heat sinks 31 is between 20 and 48, thereby realizing continued heat conduction operation on the coolant storage cylinder 1 and the cooling cylinder 3 and improving the heat conduction effect.

[0030] Specifically, a threaded adding tube 11 connected to the interior of the coolant storage tube 1 is fixedly installed on the top surface of the coolant storage tube 1, and the inner diameter of the threaded adding tube 11 is greater than 3 cm; a threaded cap 12 is threadedly connected to the threaded adding tube 11, and anti-slip stripes are provided on the annular side of the threaded cap 12 to facilitate the addition of cooling medium at the threaded adding tube 11.

[0031] Furthermore, the terminal tube body of the suction tube 20 is located near the bottom position of the coolant storage cylinder 1, and the terminal tube body of the return tube 35 is located near the top position of the coolant storage cylinder 1, so as to make the liquid flow more smoothly.
