Description

Cooling device

Technical Field

The application relates to the technical field of heat exchange devices, in particular to a cooler.

Background

At present, an EGR cooler usually comprises a core and a shell, wherein the size inside the shell must be larger than the size of the maximum position of the core in order to ensure that the core can be normally arranged in the shell, namely the outer contour position of an inner air chamber, a gap of 1-2 mm is ensured, and the core is prevented from colliding during installation. Since the outer contour of the inner air chamber is larger than the cross-sectional dimension of the cooling tube, a large gap is present between the housing and the cooling tube. Since the water-side fins are provided between the cooling tubes, which is not provided between the cooling tubes and the casing, the water-side resistance between the cooling tubes is larger than the resistance between the cooling tubes and the casing. When the cooler is in use, the water flow tends to flow to a place with low resistance, i.e. the water flow tends to flow to the space between the cooling pipe and the housing, which results in a large amount of water flow bypassing, and the core is not cooled, so that the core generates local high temperature, which affects reliability.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

As shown in fig. 1 to 5, the present application provides a cooler including a housing 300, and a core 200 and a liquid barrier 400 mounted in the housing 300, the liquid barrier 400 being mounted on the core 200, and the liquid barrier 400 being located between the housing 300 and the core 200 to guide a coolant flowing into the cooler to the core 200 through the liquid barrier 400.

The cooler that this application embodiment provided, through set up liquid blocking piece 400 between casing 300 and core 200, is clearance 600 between core 200 and the casing 300 by the separation, and liquid when flowing in, most liquid can flow to core 200, makes the coolant liquid flow that flows through core 200 more sufficient, and the cooling effect is better, has reduced local high temperature, has improved the reliability of product.

Optionally, the housing 300 has an inlet port and the liquid barrier 400 has a baffle 430 extending perpendicular to the first direction and in a direction away from the cartridge 200 or disposed at an angle relative to the first direction and in a direction away from the cartridge 200, the first direction being the direction in which the inlet port 310 faces the cartridge 200. Through this guide plate 430, increased the area that liquid baffle 400 covered between core 200 and casing 300, when having increased and blockking the effect to the coolant liquid, still played the effect of leading the coolant liquid to core 200, further improved the reliability of cooling effect and product.

Alternatively, the liquid barrier 400 has a connection part 420 connected with the cartridge 200, and the waterway fin 500 is installed between the connection part 420 and the cartridge 200. This water course fin 500 can play the effect to the coolant liquid water conservancy diversion, makes the coolant liquid distribute more evenly, and makes also can cool off through the coolant liquid between core 200 and water blocking piece, has improved the cooling effect.

Alternatively, the connection part 420 is a plate having a first plate surface disposed facing the core 200, and the waterway fin 500 is located between the first plate surface and the core 200. This increases the coverage area of the water channel fins 500, thereby improving the cooling effect.

Optionally, the liquid barrier 400 has a liquid barrier 410, and the baffle 430 is located between the liquid barrier 410 and the liquid inlet 310 in the first direction. Part of the cooling liquid may bypass the flow guide plate 430 and further bypass the core 200, thereby affecting the cooling effect, and by further providing the liquid blocking portion 410, the cooling liquid bypassing the flow guide plate 430 can be further blocked, thereby further reducing the cooling liquid bypassing the core 200, thereby further improving the cooling effect and the reliability of the product.

Optionally, the liquid blocking part 410 is an end of the liquid blocking member 400 away from the flow guide plate 430 in the first direction. Because liquid blocking portion 410 is relatively far away from the water inlet, when the coolant liquid flows to liquid blocking portion 410, the coolant liquid flow velocity is relatively small, and then the effect of blocking the coolant liquid by liquid blocking portion 410 is better.

Alternatively, the first direction is parallel to the cross-section of the wick 200, and the liquid stoppers 400 are installed on opposite sides of the wick 200 in the second direction, which is perpendicular to the first direction and parallel to the cross-section of the wick 200. When the first direction is parallel to the cross section of the core 200, when the cooling liquid flows into the housing 300, the two sides of the core 200 in the second direction are easy to flow, and the liquid blocking members 400 are arranged on the two sides to better block the cooling liquid, so that more cooling liquid flows into the core 200, and the cooling effect and the reliability of the product are improved.

Optionally, each outer wall of the cartridge 200 is covered with a liquid barrier 400. The coolant can be made to flow more intensively through the core 200, reducing the bypass space at various positions between the core 200 and the housing 300. The cross section of the core 200 is generally approximately square, and in this case, the liquid blocking members 400 are preferably four and respectively cover four outer walls of the core 200, but of course, the number of the liquid blocking members 400 may also be three, five or six, etc., and the specific number is determined according to actual needs.

Optionally, the length dimension of the liquid barrier 400 in the third direction is the same as the length dimension of the wick 200 in the third direction. The longer the length of the liquid barrier 400 covering the core 200, the more the coolant is concentrated in the core 200, the better the cooling effect, and the higher the product reliability.

Alternatively, the cooler provided by the embodiment of the present application includes the air inlet chamber 100, the core 200 has a connection section connected to the air inlet chamber 100, and the liquid blocking member 400 covers the connection section. The liquid blocking member 400 covers only a part of the core 200, and the production cost can be reduced on the premise of ensuring the cooling effect and the reliability.
