In a heat exchanger for exchanging heat between a fluid, such as a refrigerant, and air, an object is to increase the surface areas of the fins while suppressing an increase in draft resistance, so as to attain the improvement of performance. To this end, corrugated sheet fins (70) are used as the fins of a heat exchanger (60). The fins (70) are shaped in corrugated form, and the direction of their edge lines is orthogonal to the leading edge and trailing edge. In the heat exchanger (60), a plurality of corrugated sheet fins (70) are disposed at a fixed pitch axially of heat transmission pipes (61).

There is provided an autonomous driving device that improves the convenience for a driver in the switching between autonomous driving and manual driving. When the driver discovers an obstacle which cannot be detected by an autonomous driving device, and performs a driving operation which causes a manual driving switching threshold value to be exceeded for an operation time less than or equal to an operation threshold value so as to avoid the obstacle, a control unit of the autonomous driving device switches autonomous driving to manual driving, and then the control unit switches manual driving to autonomous driving even if the driver does not perform an autonomous driving switching operation. For this reason, it is possible to improve the convenience for the driver in the switching between autonomous driving and manual driving.

A device that efficiently transfers heat from a heat source. The device includes a heat sink, the heat sink comprising a thermally conductive base, and a plurality of thermally conductive pin fins coupled to the thermally conductive base. A gas source, such as a blower, proximate to the pin fins, directs a gas, such as ambient air, axially along at least a portion of the pin fins, and then in a direction radial to the pin fins and substantially parallel to the heat source, to transfer heat away from the heat source. The heat transfer device may be utilized in any application that requires efficient removal of heat from a heat source, for example, an electronic device such as an integrated circuit or microprocessor.

PROBLEM TO BE SOLVED: To resolve a problem that a conventional heat exchanger employing a circular tube or a flat tube does not permit to improve remarkably a ventilating resistance or a heat transfer performance and contrive energy saving due to the restriction in manufacturing or structure. SOLUTION: A multitude of sheet type fins are arranged in parallel and flat type heat transfer tubes are inserted from the upstream side of air flow into groove holes to braze the tube to the fin whereby the heat exchanger, miniaturized in size, reduced in a ventilating resistance and excellent in heat transfer performance can be obtained.

PROBLEM TO BE SOLVED: To solve problems wherein a heat exchange quantity of the whole heat exchanger reduces since a leeward side heat transfer pipe inside passage reduces in heat exchange efficiency though a windward side heat transfer pipe inside passage efficiently exchanges heat, and a flat heat transfer pipe is worse in drainability of dewing water than a circular pipe-shaped heat transfer pipe in a heat exchanger using the flat heat transfer pipe. SOLUTION: This heat exchanger has the heat transfer pipe arranging a plurality of passages inside a flat cross section bent in a U shape, a header for communicating with an end part of the heat transfer pipe, a vertical partition plate, and a horizontal partition plate for forming a refrigerant flow to an outflow pipe from an inflow pipe by separating a space in the header, and constitutes the refrigerant flow of an opposed flow or a parallel flow to a gas flow.
