Embodiment 1

[0062] Such as figure 1 As shown, the present invention provides a heat exchange device 1, which includes: a housing 11 provided with an air inlet and an air outlet, a heat exchange body 12 arranged between the air inlet and the air outlet of the housing 11, the heat exchange The main body 12 forms a first flow path in the direction from the air inlet to the air outlet, and the first flow path flows through the heat exchange body 12 to form a heat exchange air flow; wherein, there is formed between the heat exchange body 12 and the inner wall surface of the housing 11 that does not pass through The air drainage channel 160 of the heat exchange main body 12, the air drainage channel 160 forms a second flow path from the air inlet to the air outlet, the end of the second flow path is provided with a slit outlet, and the second flow path forms a slit at the slit outlet. Slit airflow 17; the wind speed of slit airflow 17 is greater than the wind speed of heat exchange airflow; the...

Embodiment approach

[0066] Such as figure 2 and image 3 As shown, in order to improve the drainage effect of the slit airflow 17 and its mixing effect with the heat exchange airflow, it is preferred in this implementation that the air outlet includes a first air outlet and a second air outlet, and the first air outlet and the second air outlet It is arranged on the same side of the housing 11, wherein the first air outlet is used to send out the heat exchange airflow of the first flow path, and the second air outlet is used to send out the slit airflow 17 of the second flowpath, and the slit airflow (17 ) is inclined at an angle θ to the heat exchange air flow sent from the first air outlet, and the design of this angle of 0°<θ<90° increases the drainage effect of the slit airflow 17, so that after the slit airflow 17 is blown out, the A diversion airflow 18 is generated in the direction of the first air inlet and the first air outlet, and the heat exchange airflow is generated through the hea...

Embodiment 2

[0075] The air source heat pump system of this embodiment includes a compressor 4 connected by a refrigerant pipeline, an external heat exchanger 2, a flow regulating device 3, a four-way valve 5, and an internal heat exchanger, wherein the internal heat exchanger adopts a kick The heat exchanging body 12 includes only one heat exchanging unit, which is arranged along the length direction of the housing 11 . Attached below Figure 4-5 To illustrate the further optimization of this embodiment (other unclear points can adopt the same design as that of Implementation 1 within the scope understandable by those skilled in the art):

[0076] Wherein, the heat exchange device includes a housing 11 provided with an air inlet and an air outlet, and a heat exchange main body 12 arranged between the air inlet and the air outlet of the housing. The heat exchange main body 12 forms the first direction from the air inlet to the air outlet. One flow path, the first flow path flows through t...

Abstract

The invention provides a heat exchange device and an air source heat pump system with the heat exchange device, and relates to the technical field of heating devices. By designing the heat exchange device, a flow inducing air flue of the heat exchange device can generate slit airflow, and the function of inducing heat exchange airflow needing to passing through a heat exchange body of the heat exchange device is achieved; meanwhile, after the induced heat exchange airflow is mixed with the slit airflow and / or indoor-temperature air, the mixed airflow is blown out of an air outlet of the heat exchange device, the blown-out airflow is amplified, soft air output is achieved, and the problem that in the prior art, the air output temperature is too high, and consequently the hot and dry sense is likely to be generated is solved; meanwhile, the device cooperates with the function of an electric auxiliary heating device, the effect of uniform air output is achieved, the heating manner based on radiant heating and supplemented by air forced convection is achieved, and noise is greatly lowered; and the device is narrow, so that the output air is closer to the ground, heating is more comfortable, and the appearance is small, exquisite and attractive.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a heat exchange device and an air source heat pump system having the same. Background technique [0002] With the sustained and rapid economic growth, smog has occurred frequently in recent years. When smog occurs, pollutants such as particulate matter in the atmosphere will infiltrate through the gaps in doors and windows, or enter the room under natural ventilation, leading to deterioration of indoor air quality. Especially in northern regions where heating is required in winter, the deterioration of indoor air quality is more serious. Therefore, creating a comfortable indoor environment in winter is of great significance for life, work and study. [0003] The existing air source heat pump fan can better solve the heating problem in the cold northern regions, replace coal-fired heating, and achieve clean heating. However, the existing hot air blowers have the probl...
