Description

Technical Field

[0001] The utility model relates to the technical field of waterless radiators, in particular to a waterless radiator with self-circulating wind power. Background Art

[0002] Air-to-waterless floor heating and waterless radiators use heat pump technology to transfer the heat of outdoor air into the room using refrigerant. Indoor waterless radiators use a refrigerant-air heat exchange structure, which does not require water as a heat transfer medium. It can directly release the heat of the refrigerant into the indoor air, heat the air, and then increase the indoor temperature. This technology has the characteristics of high efficiency and energy saving, comfortable use, simple construction, and maintenance-free in the later stage.

[0003] At present, air-source waterless radiators rely on refrigerant to heat the internal fins, which in turn heat the air for heating. In this way, the air circulation is a natural heating cycle, which has the following technical problems:

[0004] 1. The air is heated to form a density difference, and the natural circulation is small, resulting in a small amount of heat released by the radiator and a slow heating speed. To ensure the heat release, the size of the radiator needs to be increased, resulting in high costs;

[0005] 2. Due to the low velocity of the natural circulation airflow, the airflow disturbance on the internal fins is small, which cannot effectively reduce the thickness of the fin air boundary layer, and the heat dissipation efficiency of the fins is low;

[0006] 3. It cannot actively adjust the heat dissipation according to the user's heating needs; it heats slowly when the room temperature is low, and it cannot actively reduce the heat release when the room temperature is high.

[0007] Due to the above reasons, the inventors have conducted in-depth research on the structure and working principle of waterless radiators, hoping to design a new waterless radiator structure that can solve the above problems. Utility Model Content

Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0045] According to the utility model, a waterless radiator with self-circulating wind power is provided, such as Figure 1 and Figure 2 As shown in the figure, the waterless heater comprises: a housing 1, in which a plurality of microchannel heating tubes 3 are arranged in parallel with each other, and a collecting tube 2 is arranged at both ends of each microchannel heating tube 3; the collecting tubes 2 may be arranged in two or more numbers, and when there are multiple collecting tubes, they are connected to each other through the microchannel heating tubes 3;

[0046] The heat source gas can enter the radiator from a collecting pipe, pass through multiple microchannel heating tubes, and then flow out from another collecting pipe. The flow path of the heat source gas in the multiple microchannel heating tubes 3 can have multiple setting schemes according to the working conditions. For example, it can be set as follows: multiple microchannel heating tubes 3 are connected in parallel with each other, and the heat source gas flows from the collecting pipe 2 on one side to the collecting pipe 2 on the other side; it can also be set as follows: the heat source gas enters the radiator through the first collecting pipe 2, passes through the microchannel heating tube 3 to enter another collecting pipe, and then passes through the microchannel heating tube 3 back to the first collecting pipe 2.

The air flow path is more complicated, but the contact between the air and the heat dissipation ribs 4 is more sufficient; any method can be selected to arrange the heat dissipation ribs 4 based on actual needs.

[0059] The arrangement of the heat sink fins can also be set as follows Figure 5 and Figure 6 In the form shown in the figure, heat dissipation fins 4 are arranged on both sides of the microchannel heating tube 3. The overall thickness of the waterless radiator is increased, but the heat exchange effect is more superior, and the setting can be selected according to actual needs.
