DETAILED DESCRIPTION

[0015] The present invention is further described below with reference to the accompanying drawings and embodiments, but is not intended to be limiting of the present invention.

[0016] As shown in the figure, a top-mounted plate heat exchanger connection mechanism is provided with a heat exchanger inlet connection mechanism 100, which is composed of a heat exchanger inlet matching flange (or threaded pipe fitting) 20, an inlet elbow (or elbow) 10-1, an inlet seal 30, and an inlet connection fastener 40; a heat exchanger outlet connection mechanism 200 is composed of a heat exchanger outlet matching flange (or threaded pipe fitting) 50, an outlet elbow (or elbow) 10-2, an outlet connection fastener 60, and an outlet seal 70.

[0017] Furthermore, the plate heat exchanger 80 can be installed upright or inverted.

[0018] Furthermore, the above-mentioned top-mounted plate heat exchanger connection mechanism is characterized in that: the heat exchanger inlet connection mechanism 100 has a U-shaped or S-shaped bend, and the heat exchanger outlet connection mechanism 200 has a U-shaped or S-shaped bend.

[0019] Furthermore, the aforementioned top-mounted plate heat exchanger connection mechanism is characterized in that its inlet connection mechanism 100 and outlet connection mechanism 200 ensure that part of the pipelines therein are higher than the upper surface of the plate heat exchanger 80 at the same time.

[0020] Furthermore, the inlet seal 30 and the outlet seal 70 may be gasket seals, O-ring seals, or sealant seals.

[0021] In order to better understand the present invention, the present invention is further described below in conjunction with specific embodiments and drawings. A top heat exchanger connection mechanism, lubricating oil enters the plate heat exchanger 80 through the inlet elbow (or elbow) 10-1 of the heat exchanger inlet connection mechanism 100 and the heat exchanger inlet matching flange (or threaded pipe fitting) 20, and flows out through the heat exchanger outlet matching flange (or threaded pipe fitting) 50 and the outlet elbow (or elbow) 10-2 of the heat exchanger outlet connection mechanism 200, wherein the heat exchanger inlet matching flange (or threaded pipe fitting) 20 and the plate heat exchanger 80 An inlet seal 30 is installed between the heat exchanger outlet matching flange (or threaded pipe fitting) 50 and the plate heat exchanger 80, and is fastened with an outlet seal 70, which is fastened with an outlet connection fastener 60. Since the inlet connection mechanism 100 and the outlet connection mechanism 200 are both higher than the upper surface of the plate heat exchanger 80, according to the communicating vessel principle, the lubricating oil entering the plate heat exchanger 80 from the inlet connection mechanism 100 can flow out of the outlet connection mechanism 200 only after filling the plate heat exchanger 80, thereby ensuring that sufficient lubricating oil is filled in the heat exchanger for heat exchange.

[0022] The top-mounted plate heat exchanger adopts this plate heat exchanger connection mechanism, which can ensure that sufficient lubricating oil is filled in the heat exchanger, fully utilize the heat exchange area of ​​the heat exchanger, thereby improving its heat exchange efficiency and ensuring the normal operation of the air compressor.

[0023] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
