5results about How to "Avoid bypass" patented technology

The heat exchanger comprises a heat exchange core body, the heat exchange core body comprises a middle heat exchange piece and two end heat exchange pieces, and the two end heat exchange pieces are connected to the two ends of the middle heat exchange piece respectively and matched with the middle heat exchange piece in an inserted mode. Cooling water at the cooling water inlet is suitable for sequentially passing through the flow inlet area and the flow outlet area and then flowing to the cooling water outlet, a refrigerant at the refrigerant inlet is suitable for flowing between the end refrigerant flow channels of the two end heat exchange pieces through the middle refrigerant flow channel and flowing to the refrigerant outlet, and the refrigerant in the middle refrigerant flow channel is suitable for exchanging heat with the cooling water. The elastic piece, the refrigerant inlet and the refrigerant outlet all communicate with the end refrigerant flow channel of one end heat exchange piece in the two end heat exchange pieces, and the elastic piece elastically abuts against the position between the other end heat exchange piece in the two end heat exchange pieces and the shell. According to the heat exchanger provided by the embodiment of the utility model, the heat exchange capacity of the heat exchange core body can be improved, so that the heat exchange efficiency of the heat exchanger is improved.

A bypass flow prevention device in a lamella heat exchanger comprises a heat exchanger shell and a heat exchange plate unit, the heat exchange plate unit is coaxially arranged in the heat exchanger shell, and two identical bypass flow blocking structures are arranged between the inner circumferential faces of the two ends of one diameter of the heat exchanger shell and the outer circumferential face of the heat exchange plate unit. The bypass flow blocking structure comprises a vertical plate and an arc-shaped elastic baffle, the vertical plate is fixedly connected to the outer circumference of the heat exchange plate unit and arranged in the radial direction of the heat exchange plate unit, one side of the arc-shaped elastic baffle is fixedly connected to one side of the vertical plate, and the other side of the arc-shaped elastic baffle is arranged on the inner circumferential face of the heat exchanger shell in an offset mode. Stop iron is fixedly arranged in the inner circumferential face of the heat exchanger shell, and the vertical plate is fixedly connected with the stop iron. Cold fluid bypass flow is prevented through the arc-shaped elastic baffles, the heat exchange efficiency is improved, and the occupied space of the heat exchanger is effectively reduced.

The invention relates to the technical field of heat exchange devices, in particular to a shallow geothermal energy double-U-shaped heat exchange device which comprises a heat exchanger and a pipeline, the pipeline is mounted above the heat exchanger, a heat exchange mechanism is arranged in the heat exchanger and comprises a quick release unit and a filter unit, the quick release unit is mounted in the heat exchanger, and the filter unit is mounted in the heat exchanger. And the filtering unit is mounted in the pipeline. According to the shallow geothermal energy double-U-shaped heat exchange device, by installing the quick disassembly unit, when a heat exchange pipe needs to be quickly disassembled and maintained, external connecting rods penetrate through the interiors of the connecting blocks to connect the two connecting blocks, so that the connecting blocks are driven by the connecting rods to move towards the two sides, and then the connecting blocks drive special-shaped blocks to move towards the outer side; and a telescopic column is retracted into a telescopic cylinder, so that a connecting spring is recovered, contact locking of a clamping block is relieved, quick disassembly and replacement of a heat exchange pipe can be completed, and the convenience of the device is improved.
