However, the core in the prior art is a porous structure, and the cooling liquid flows from the inlet water chamber to the outlet water chamber through the holes of the core. The porous structure of the core body can increase the flow resistance of the cooling liquid, the resistance is called heat exchanger water resistance, and the flow resistance of the external cooling air is also increased, the resistance is called heat exchanger wind resistance, the increase of the water resistance and the wind resistance can reduce the flow of the cooling liquid and the flow of the cooling air flowing through the heat exchanger, so that the heat radiation performance of the heat exchanger is reduced, the power loss of a water pump and a cooling fan can be increased, the reliability of the heat exchanger can be reduced due to too large water resistance, and the failure rate of the water pump is increased.

SUMMERY OF THE UTILITY MODEL

The utility model provides a heat exchanger can improve heat dispersion.

Preferably, the water diversion chamber is provided with a water diversion plate, and the first water chamber and the second water chamber are separated by the water diversion plate.

Preferably, the water diversion plate is obliquely arranged.

By adopting the technical scheme, after the high-temperature cooling liquid is discharged through the main water inlet pipe, one part of the high-temperature cooling liquid enters the first heat exchanger core body through the first water inlet branch pipe and the water inlet chamber, the other part of the high-temperature cooling liquid enters the second heat exchanger core body through the second water inlet branch pipe and the second water chamber in sequence, the cooling fan works and blows in low-temperature natural air, so that the high-temperature cooling liquid in the first heat exchanger core body and the high-temperature cooling liquid in the second heat exchanger core body complete heat exchange in the respective core bodies, the temperature of the cooling liquid is reduced, the temperature of the natural air is increased, the heated natural air is blown away from the core bodies by the cooling fan to take away heat, one part of the cooled cooling liquid is discharged to the main water outlet pipe through the first water chamber and the second water outlet branch pipe in sequence, and the other part of the. Because the utility model discloses heat exchanger has adopted the shunting design, can accomplish the heat exchange of coolant liquid through two heat exchanger cores, compares in adopting a heat exchange core, and the heat exchange in two cores is all accomplished under great liquid-gas difference in temperature, and the radiating efficiency is higher. The required thickness of the heat exchanger core is therefore smaller, with a corresponding smaller volume and weight, while still satisfying the heat exchange performance.
