Problems solved by technology

[0005] First: The blowing evaporator is a whole structure, and it is installed outside the building with a large area for driving, and the middle strength is not enough, and the whole board is easily deformed by force;
[0006] Second: Due to the large size of the blowing evaporator, its own strength is not enough, and it will vibrate continuously after a ride, resulting in noise;
[0007] Third: The refrigerant absorbs heat and evaporates in the flow channel of the blowing evaporator, because the air does not flow in front of and behind the whole plate, and the heat exchange with the air absorbs less heat during the evaporation process, making the evaporation efficiency low

Embodiment 1

[0038] Such as figure 2 and image 3 As shown, in this embodiment, the hollow part 2 is formed by punching holes punched on the plate constituting the evaporator 1 . The hollow part is formed by punching, so that the evaporator can realize the molding of the hollow part during the pressing process, so as to simplify the manufacturing process of the evaporator and improve the overall strength.

[0039] In this embodiment, the plate at the punched hole is punched and bent to form a flange 21 extending toward the front side of the evaporator 1 . By protruding and bending the punched flanging toward the front side of the evaporator, the flanging can be in contact with sunlight, increasing the heat absorption area, and achieving the purpose of rationally setting the hollow part to increase the heat absorption area.

[0040] In this embodiment, the flanging 21 is in the shape of an arc that becomes smaller from top to bottom. The upper side of the flanging 21 is connected to the ...

Embodiment 2

[0043] Such as figure 2 As shown, in this embodiment, the evaporator 1 is arranged with a plurality of straight pipe flow passages 31 parallel to the axis of the evaporator 1 and arranged at intervals, and the gap between adjacent straight pipe flow passages 31 is provided with a hollow part 2 . The hollow part 2 is arranged horizontally along the axis of the evaporator 1 to reduce the vibration of the evaporator caused by the airflow passing through the hollow part.

[0044] In this embodiment, multiple rows of hollowed out parts 2 are arranged, and each row includes a plurality of hollowed out parts 2 arranged at intervals. Each row of hollowed out parts 2 is arranged between the same group of adjacent straight pipe runners 31 , and the axes of the row of hollowed out parts 2 are at the same height plane. Preferably, two sections of straight pipe flow passages 31 are spaced between adjacent rows of hollows 2, so that the distance between adjacent rows of hollows is modera...

Embodiment 3

[0048] Such as figure 2 and Figure 4As shown, in this embodiment, a condensed water collection tank 4 is provided on the lower side of the evaporator 1 to collect the condensed water generated on the surface of the evaporator, so as to prevent the condensed water from falling along the plate surface and causing water accumulation on the installation ground. occur.

[0049] In this embodiment, the lower side of the evaporator 1 is provided with a stamping flange that is formed by stamping and extends horizontally. A condensed water collecting tank 4 is formed. A certain flowing water gap 5 is provided between the lower side of the stamping flange and the evaporator, so that the condensed water collected in the condensed water collecting tank 4 can overflow through the flowing water gap. The back side of the evaporator 1 on the lower side of the water flow gap 5 is provided with a diversion groove 6, and the diversion groove 6 is composed of a through groove with an upper e...

Abstract

The invention relates to a solar heat pump evaporator with a hollowed middle part and a water heater. The evaporator is a plate type evaporator formed by performing pressing and huffing treatment on two plates; hollow bulges formed by huffing are arranged on the evaporator; the hollow parts forms a runner where a coolant medium flows; hollowed parts staggered from the runners are formed in the evaporator; and the hollowed parts are provided with gaps penetrating through the plate surfaces. By the formation of the hollowed parts in the evaporator formed by huffing of the whole plates, air flow can penetrate through the evaporator from the hollowed parts to reduce the impact strength of the air flow to the whole plates of the evaporator; furthermore, the contact area between the evaporator and the air flow is enlarged, so that the heating efficiency of the evaporator is improved; and meanwhile, the solar heat pump evaporator is simple in structure, outstanding in effect and suitable for being popularized and used.

Description

technical field [0001] The invention relates to a solar heat pump water heater in the field of water heaters, in particular to a hollow solar heat pump evaporator. Background technique [0002] At present, evaporators are mostly used in refrigerators, freezers, wine cabinets, air energy heat pumps and other products on the market. Solar heat pump evaporators appear in the market later, and the products are larger than refrigerators, freezers, wine cabinets, and air energy heat pump evaporators. Although it appeared late, solar heat pump water heaters have developed rapidly because of their advantages such as high heat conduction efficiency and fast heat exchange rate. [0003] As one of the main components in the heat pump system, the performance of the evaporator directly determines the heating performance and heat transfer coefficient of the solar heat pump system. At present, solar heat pump evaporators in the market mainly include finned evaporators, plate tube evaporat...
