[0022] like figure 1 As shown, the charge air cooling unit X1 according to the first embodiment is a unit for cooling the charge air supplied from the supercharger 1 to the engine 2 . In the first embodiment, the charge air cooling unit X1 is mounted on a ship traveling by the power of the engine 2 . Specifically, the charge air cooling module X1 according to the first embodiment includes an energy recovery device 6 , a cooling device 8 , a detection sensor 9 and a control unit 10 . These components are mounted on a ship together with a turbocharger 1 , an engine 2 , a scavenging line 3 , and an exhaust line 4 .

[0023] The cooler 5 includes an evaporator part 5 a provided on the energy recovery device 6 and a gas cooler part 5 b provided on the cooling device 8 . In the evaporator unit 5a, the supercharged air supplied from the supercharger 1 to the engine 2 exchanges heat with the working medium, and the working medium evaporates. In the gas cooler unit 5b, the superchar...

[0073] Below, refer to Figure 5 The charge air cooling module X1 according to the second embodiment will be described. In addition, in this embodiment, only the part which differs from 1st Embodiment is demonstrated, and the same code|symbol as 1st Embodiment is attached|subjected to the same structural part as 1st Embodiment, and description is abbreviate|omitted.

[0074] Figure 5 and Figure 4 It is also a partial enlarged view of side view cooler 5 . In the charge air cooling assembly X1 related to the second embodiment, as Figure 5 As shown, the second heat transfer tube 623a is disposed at a position from the inside of the step portion 322a to the inside of the step portion 322b of the supercharged air flow path S2. That is, the second heat transfer tube 623a is arranged in the first region 322c.

[0075] The second heat transfer tube 623 a is formed to have the same flow path width of the working medium as that of the first heat transfer tube 622 . That is to s...

[0078] Below, refer to Image 6 The charge air cooling module X1 according to the third embodiment will be described. In addition, in this embodiment, only the part which differs from 1st Embodiment is demonstrated, and the same code|symbol as 1st Embodiment is attached|subjected to the same structural part as 1st Embodiment, and description is abbreviate|omitted.

[0079] Image 6 It is an enlarged view showing the flow of charge air in the vicinity of the evaporator portion 5a of the charge air cooling module X1. In the charge air cooling module X1 according to this embodiment, as Image 6 As shown, in the first case 31 of the scavenging line 3, an inclined portion 31b is formed on the side surface on the side where the engine 2 is arranged. The inclined portion 31b is inclined such that the width of the flow path of the supercharged air gradually increases toward the connecting portion where the first shell 31 and the first cooling shell 32a are connected. Therefore, th...

Abstract

A supercharge air cooling unit provided by the invention includes an evaporator portion in which heat exchange is conducted between supercharging air to be supplied from a supercharger to an engine and a working medium to evaporate the working medium; an expander into which the working medium evaporated in the evaporator portion flows; a motive power recovery device which recovers motive power ofthe expander; and a gas cooler portion in which heat exchange is conducted between the supercharging air cooled by the evaporator portion and a cooling medium to further cool the supercharging air, inwhich forming a flow path of the supercharging air in the evaporator portion to have a width larger than a width of a flow path of the supercharging air in the gas cooler portion results in forming astepped portion in a flow path of the supercharging air in the evaporator portion, and the evaporator portion is configured such that a flow rate of the working medium passing through in a first region expanded by the stepped portion is smaller than a flow rate of the working medium passing through in a second region in the evaporator portion. Therefore, the working medium of an air accumulationpart through which supercharging air passes can be evaporated reliably.

Description

technical field [0001] The invention relates to a charge air cooling assembly. Background technique [0002] Conventionally, a charge air cooling unit for cooling charge air supplied to an engine of a ship or the like is known. As an example of such a charge air cooling unit, Patent Document 1 describes an intake line connecting the engine and the supercharger, an exhaust heat recovery device for recovering heat energy of the charge air passing through the intake line, and cooling through the intake line. Components of the gas cooler for the charge air of the gas line. [0003] The exhaust heat recovery device disclosed in Patent Document 1 has a heater that heats a working medium, an expander into which the working medium flowing out of the heater flows, and a power recovery machine connected to the expander. In the heater, the charge air passing through the suction line exchanges heat with the working medium. Accordingly, the charge air is cooled and the working medium ...
