Abstract
A heat exchanger includes an outer sleeve provided with two open ends, and at least one diversion unit group provided in the outer sleeve. A first flow channel is formed between the outer sleeve and the diversion unit group for a first fluid to flow from one end to the other end of the outer sleeve. The diversion unit group includes a first hollow vane, a connecting channel and a second hollow vane sequentially provided along an axial direction of the outer sleeve. The first hollow vane, the connecting channel and the second hollow vane are sequentially connected to form a second flow channel for the second fluid to flow from one end to the other end of the outer sleeve.
Claims12
A heat exchanger, comprising:
- an outer sleeve provided with two open ends;
- and
- at least one diversion unit group provided in the outer sleeve,
- wherein:
- a first flow channel is formed between the outer sleeve and the diversion unit group for a first fluid to flow from one end to the other end of the outer sleeve,
- the diversion unit group comprises a first hollow vane, a connecting channel, and a second hollow vane sequentially provided along an axial direction of the outer sleeve, and
- the first hollow vane, the connecting channel and the second hollow vane are sequentially connected to form a second flow channel for a second fluid to flow from one end to the other end of the outer sleeve, wherein the first hollow vane, the connecting channel, and the second hollow vane are twisted and inclined relative to an axis of the outer sleeve and a twist and incline direction of the first hollow vane and the second hollow vane are the same, and a twist and incline direction of the connecting channel and the first hollow vane are opposite.
A heat pump system, comprising:
- a compressor;
- a condenser;
- a throttle valve;
- and
- an evaporator,
- wherein the compressor, the condenser, the throttle valve, and the evaporator are communicated with each other to form a circulation circuit, and the condenser adopts a heat exchanger comprising:
- an outer sleeve provided with two open ends;
- and
- at least one diversion unit group provided in the outer sleeve,
- wherein:
- a first flow channel is formed between the outer sleeve and the diversion unit group for a first fluid to flow from one end to the other end of the outer sleeve,
- the diversion unit group comprises a first hollow vane, a connecting channel, and a second hollow vane sequentially provided along an axial direction of the outer sleeve, and
- the first hollow vane, the connecting channel and the second hollow vane are sequentially connected to form a second flow channel for a second fluid to flow from one end to the other end of the outer sleeve, wherein the first hollow vane, the connecting channel, and the second hollow vane are twisted and inclined relative to an axis of the outer sleeve and wherein a twist and incline direction of the first hollow vane and the second hollow vane are the same, and a twist and incline direction of the connecting channel and the first hollow vane are opposite.
