[0007] However, in the above-mentioned structure, the high-temperature cooling water after receiving heat from the exhaust gas does not pass through the oil cooler or the ATF heater, but is introduced into the water jacket inlet of the internal combustion engine.
Therefore, the heat of the cooling water passing through the EGR cooler cannot be utilized for warm-up by the oil cooler or ATF heater

no. 1 approach

[0023] Below, refer to Figure 1 ~ Figure 4 A first embodiment in which a heat exchange device for a vehicle is realized will be described. The vehicle of the present embodiment is equipped with an internal combustion engine 10 and an automatic transmission 30 .

[0024] The internal combustion engine 10 in the present embodiment is a gasoline engine, and is provided with: an intake passage 11 for sending air into the combustion chamber; and an exhaust passage 12 for taking the combustion gas burned in the combustion chamber as Exhaust gas is discharged. The EGR passage 13 is connected to the intake passage 11 and the exhaust passage 12 , and is used to return the exhaust gas flowing in the exhaust passage 12 to the intake passage 11 . In addition, the EGR passage 13 is provided with an EGR valve 14 for adjusting the recirculation amount of exhaust gas. The EGR valve 14 in the present embodiment is integrally formed with a valve heat exchange portion 15 for exchanging heat ...

no. 2 approach

[0067] Next, refer to Figure 5 A second embodiment of the heat exchange device 2 for a vehicle will be described. Such as Figure 5 As shown, unlike the cooling water circuit 40 of the first embodiment, the cooling water circuit 43 of the vehicle heat exchange device 2 of the second embodiment is not provided with a control valve 46, so that the upstream end of the first heat exchange passage 50 and the second The upstream end of the second heat exchange passage 51 is connected to the outlet-side passage 42 connected to the water jacket outlet 22 . In addition, the downstream end of the first heat exchange passage 50 and the downstream end of the second heat exchange passage 51 are connected to the upstream end of the inlet side passage 41 via a thermostat valve 56 . In addition, for the same structure as the first embodiment, in Figure 5 In , the same reference numerals as those in the first embodiment are used, and descriptions thereof are appropriately omitted.

Abstract

A heat exchange apparatus of a vehicle is provided, and can reduce engine warming time based on an oil cooler and an ATF heater through effectively utilizing the heat received by cooling water in an ECR cooler from exhaust gas. The heat exchange apparatus (1) is provided with a cooling water return (40) between a water sleeve outlet (22) of an internal combustion engine (10) to a water sleeve inlet (21). The cooling water return connects a water pump (45), the EGR cooler (17), the oil cooler (25) and the ATF heater (35). The EGR cooler allows the cooling water and exhaust gas flowing through an EGR path (13) to exchange heat. The oil cooler allows engine oil and the coolant to exchange heat. The ATF heater allows the cooling water and ATF adopted as working oil of an automatic transmission (30) to exchange heat. In the cooling water return, the oil cooler and the ATF heater are connected at the downstream of the EGR cooler.

Description

technical field [0001] The present invention relates to a heat exchange device for a vehicle. Background technique [0002] The vehicle heat exchange device disclosed in Patent Document 1 includes a cooling water circuit that connects an oil cooler and a heater in parallel between a jacket water outlet and a water jacket inlet of an internal combustion engine. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2014-196708 [0004] As in the cooling water circuit disclosed in Patent Document 1, it is conceivable to connect the EGR cooler, the oil cooler, and the ATF heater in parallel as a method of connecting the heat exchangers in parallel between the jacket water outlet and the water jacket inlet of the internal combustion engine. The way you connect. In this case, the cooling water flowing out from the outlet of the water jacket of the internal combustion engine splits and flows to the EGR cooler, the oil cooler, and the ATF heater. [0005] Here, in the oil coo...
