Heat exchanger structure

Abstract

The invention relates to the field of heat exchangers and discloses a heat exchanger structure. The heat exchanger structure comprises a heat exchanger shell, wherein a water heat radiator and an intercooler are arranged in the heat exchanger shell; the water heat radiator comprises a plurality of heat radiating water pipes; the intercooler comprises a plurality of intercooling air pipes; the heat exchanger shell is provided with an air inlet side and an air outlet side; and the heat radiating water pipes comprise first water pipes, second water pipes and first elbows for connecting the first water pipes and the second water pipes, the first elbows are arranged around the intercooling air pipes, the first water pipes and the second water pipes are separately arranged at the two sides of the intercooling air pipes, the second water pipes are located at the air inlet side, and the first water pipes are located at the air outlet side; or the intercooling air pipes comprise first air pipes, second air pipes and second elbows for connecting the first air pipes and the second air pipes, the second elbows are arranged around the heat radiating water pipes, the first air pipes and the second air pipes are separately arranged at the two sides of the heat radiating water pipes, the second air pipes are located at the air inlet side, and the first air pipes are located at the air outlet side. The heat exchange efficiency of the heat exchanger can be increased.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a heat exchanger structure. Background technique [0002] There are two types of radiators and intercoolers: series and parallel. When arranged in series, the intercooler is in the front and the water radiator is in the back, such as figure 1 As shown, the cold test air first passes through the intercooler air pipe 3 and then passes through the heat dissipation water pipe 2. In order to reduce the ventilation loss, the core body front dimensions of the radiator and the intercooler should be the same as possible; they are arranged in series, easy to install, and simple to calculate. The cold air of the cooler absorbs the heat emitted by the intercooler, and the temperature rises, which increases the heat load of the radiator. Therefore, the front area and heat dissipation area of ​​the radiator have to be increased in design, and the intercooler has also been enlarged. f...

AI Technical Summary

Problems solved by technology

Since the air resistance curves of the two heat exchangers of the radiator and the intercooler are different, in order to meet the heat dissipation requirements of the two at the same time, the frontal areas of the two are properly allocated under the condition of limited frontal dimensions, and the air volume is balanced, but due to being cooled The properties and temperature of the fluid medium are different, which will still cause the temperature rise of the cooling air passing through the intercooler to be small and waste energy
