Abstract
The invention relates to a heat exchanger having a manifold plate structure. The heat exchanger comprises a first and a second manifold plate. The first and second manifold plates allow a refrigerant communication between an outside of the heat exchanger and another plate. The manifold plates together form a closed flat tube and each of the manifold plates has a pair of cup portions. The first manifold plate has a first slot and the second manifold plate has a second slot. The edge of the first slot has a projected burr portion. The first slot is configured for insertion into a slot of a first adjacent plate that is configured to be connected to the first manifold plate. The length and width of the first slot are less than the length and width of the second slot.
Claims5
A heat exchanger having a manifold plate structure, comprising:
- a first end plate and a second end plate, each end plate being configured on a respective side end of the heat exchanger;
- and
- a plurality of flat tubes, the flat tubes being stacked together so that plates constituting the flat tubes are arranged in the order of the second end plate, a first plurality of pairs of plates, a first pair of manifold plates to which a refrigerant inflow pipe is connected, the first pair of manifold plates having a first manifold plate which is located at a side of the first end plate and second manifold plate which is located at a side of the second end plate, a second plurality of pairs of plates, a second pair of manifold plates to which a refrigerant outflow pipe is connected and a third plurality of pairs of plates configured adjacent to the first end plate;
- wherein a first burr portion projected from an edge of an inlet-side slot of the first manifold plate to an outside is fixedly inserted into a first slot of a plate among the second plurality of pairs of plates adjacent to the first manifold plate, and a second burr portion projected from an edge of a second slot of a plate among the first plurality of pairs of plates adjacent to the second manifold plate is fixedly inserted into an inlet-side slot of the second manifold plate, and
- wherein each of the length and width of the first slot and the length and width of the inlet-side slot of the first manifold plate is less than the length and width of the inlet-side slot of the second manifold plate, respectively.
