  • Patent number: 10731927
    Abstract: A plate-type heat exchanger includes a first heat exchange section and a second heat exchange section that includes a refrigerant flow path independent of the first heat exchange section. Each of the first and second heat exchange sections includes a fixed support supporting heat transfer plates from one end side in an arrangement direction, and a moving support supporting the heat transfer plates at a first support position on the other end side of the arrangement direction. The moving support is moved from the first support position to a retracted position separated in the arrangement direction to form a first removal region between the first support position and a second retracted position, and the heat transfer plates are removed through the first removal region. The first removal region and the second removal region of the second heat exchange section are overlapped with each other.

  • Patent number: 10495385
    Abstract: A heat exchange device of a floating core type, having a special configuration which allows increasing its durability as it increases its thermal fatigue resistance. The device is characterized by a configuration having high thermal fatigue resistance due to the special configuration of the end where the floating side of the core is located since stagnation regions that are usually produced in the baffle of the floating end are eliminated by the combination of the shape of the shell and of a deflector. This configuration furthermore results in a low-cost exchanger.

Moreover collision safety of passengers is improved, and an interior space of a vehicle is expanded forward. In an air-conditioning unit to be positioned to the front of a front seat of a vehicle, an evaporator is positioned below and behind a blower, and a heater core is positioned below and in front of the blower. Preferably the air-conditioning unit is of a crushable structure wherein, in the event of a vehicle collision, a wall of the main cover behind the evaporator is broken, or component parts housed within the main cover are moved, to thereby absorb the impact energy.

  • Patent number: 7743817
    Abstract: A thermal module includes a fixing rack and a heat sink fitted in the fixing rack. The fixing rack is provided at an inner side with at least one stopper and at least one projected portion adjacent to and vertically lower than the stopper by distance. The heat sink is provided along an outer periphery at a predetermined position with at least one vertically extended groove. By vertically turning the heat sink by 180 degrees, the heat sink may be selectively fitted in the fixing rack with an upward-facing side thereof upward abutted on the upper stopper or the lower projected portion to restrict the fixing rack from sliding downward. Meanwhile, due to the height difference between the stopper and the projected portion, a distance between the upward-facing side of the heat sink and the fixing rack is adjustable.

  • Patent number: 7370692
    Abstract: A heat dissipating structure having different compactness assembled from a plurality of small heat dissipating fins, thereby forming heat dissipation areas having different spacing. The heat dissipating fins are stamp formed from single strips, and spacing of each of the heat dissipating fins is predetermined when assembling to constitute the structure. The heat dissipating fins are completed from a single stamping, and can be assembled to form heat dissipation areas of different spacing to accommodate a cool air flow being fanned from different oriented fans, thereby reducing obstruction and disturbance of the air flow and rapidly and smoothly guiding the air flow to other heat dissipating fins. Moreover, the heat dissipating structure enlarges area of heat circulation, thereby augmenting speed of heat diffusion, improving heat dissipation effect on heat emitting from computer electronic components, and enhancing functionality of the fan.
