Below with reference to the accompanying drawings the heat exchanger 1 for air conditioner room unit according to the utility model embodiment is described.
The top of described air conditioner room unit has air inlet, and heat exchanger 1 is finned heat exchanger, and heat exchanger 1 is located at (above-below direction is as shown in the arrow A in Fig. 1) below described air inlet.
As shown in Figure 1, according to the utility model embodiment for comprising the first separate refrigerant flow and the second refrigerant flow in the heat exchanger 1 of air conditioner room unit.
Described first refrigerant flow has the first import 110 and the first outlet 120, and described second refrigerant flow has the second import 210 and the second outlet 220.
Heat exchanger 1 comprises front upper heat exchanger 300, rear heat exchanger 400 and front lower heat exchanger 500.
The arrangement in inverted V-shaped of front upper heat exchanger 300 and rear heat exchanger 400, rear heat exchanger 400 is connected with the upper end of front upper heat exchanger 300, and after heat exchanger 400 and front upper heat exchanger 300 lower end mutually away from, first import 110 and the second import 210 are formed on front upper heat exchanger 300, the windward side of the first import 110 and the contiguous front upper heat exchanger 300 of the second import 210 is arranged, the top of the contiguous front upper heat exchanger 300 of the first import 110 is arranged, the bottom of the contiguous front upper heat exchanger 300 of the second import 210 is arranged, front upper heat exchanger 300 be provided be communicated with the first import 110 first before upper outlet 310 and be communicated with the second import 210 second before upper outlet 320, before first, before upper outlet 310 and second, the lee face of the contiguous front upper heat exchanger 300 of upper outlet 320 is arranged, and upper outlet 310 is positioned at the below of upper outlet 320 before second before first, second outlet 220 is formed on rear heat exchanger 400.Front lower heat exchanger 500 is located at the lower end of front upper heat exchanger 300, and the first outlet 120 is formed on front lower heat exchanger 300.Here it is to be appreciated that " leeward side " refers to the side of heat exchanger 1 near the wind wheel of described air conditioner room unit, " windward side " depends on the side of the air inlet of nearly described air conditioner room unit.
According to the heat exchanger 1 for air conditioner room unit of the utility model embodiment, by arranging separate described first refrigerant flow and described second refrigerant flow in heat exchanger 1, and described first refrigerant flow has the first import 110 and the first outlet 120, described second refrigerant flow has the second import 210 and the second outlet 220.Cold-producing medium can be made to flow through heat exchanger 1 by two imports and two outlets.Compare in correlation technique and adopt three to enter the heat exchanger that three go out mode, for the heat exchanger 1 of air conditioner room unit owing to having two independently refrigerant flows, do not need to arrange distributor, not only save cost, and the diameter changing mechanism can avoiding in the undue orchestration of flow of refrigerant, prevent the flowing of this variable-diameter structure to cold-producing medium from causing resistance, ensure the flow velocity of cold-producing medium, the heat transfer effect of easy raising heat exchanger 1, and turbulization when can avoid flow of refrigerant, to avoid producing noise in refrigerants vaporize process, thus reduce the noise of described air conditioner room unit.
And, the mode entering scene 2 owing to adopting two for the heat exchanger 1 of air conditioner room unit, each refrigerant flow is made to have independently import and outlet, compare employing one in correlation technique and enter the heat exchanger of scene 2 mode, the pressure loss that cold-producing medium produces when shunting can be avoided, to reduce the refrigerant crushing of heat exchanger 1, ensure the pressure in each refrigerant flow, ensure the flow velocity of cold-producing medium, thus ensure the heat exchange efficiency of heat exchanger 1, and due to described first refrigerant flow and described second refrigerant flow separate, cold-producing medium bias current can be avoided, affect the heat transfer effect of heat exchanger, ensure the uniformity of heat exchange.
In addition, because the windward side of the first import 110 and the contiguous front upper heat exchanger 300 of the second import 210 is arranged, the top of the contiguous front upper heat exchanger 300 of the first import 110 is arranged, the bottom of the contiguous front upper heat exchanger 300 of the second import 210 is arranged, before first, before upper outlet 310 and second, the lee face of the contiguous front upper heat exchanger 300 of upper outlet 320 is arranged, and upper outlet 310 is positioned at the below of upper outlet 320 before second before first, described first refrigerant flow and described second refrigerant flow not only can be made all through front upper heat exchanger 300, because front upper heat exchanger 300 is nearer apart from described air inlet, air quantity is larger, by described first refrigerant flow and described second refrigerant flow are arranged at the partial intersection of front upper heat exchanger 300, can enable described first refrigerant flow and described second refrigerant flow more abundant in the part heat exchange of front upper heat exchanger 300, so that improve the heat exchange efficiency of described first refrigerant flow and described second refrigerant flow, and due to the air quantity more front lower heat exchanger 500 of rear heat exchanger 400 and front upper heat exchanger 300 large, heat transfer effect is better, by the bottom of contiguous for the second import 210 front upper heat exchanger 300 is arranged, upper outlet 310 before first is located at the below of upper outlet 320 before second, the part of described second refrigerant flow on front upper heat exchanger 300 flowing through rear heat exchanger 400 can be made to be arranged on the lee face of front upper heat exchanger 300 as far as possible, and by the top of contiguous for the first import 110 front upper heat exchanger 300 is arranged, just upper outlet 310 is located at the below of upper outlet 320 before second before first, the part of described first refrigerant flow on front upper heat exchanger 300 flowing through front lower inlet 510 can be made to be arranged on the windward side of front upper heat exchanger 300 as far as possible.That is, due to described first refrigerant flow, to compare described second refrigerant flow at the heat exchange efficiency of the part of front lower heat exchanger 500 poor at the heat exchange efficiency of the part of rear heat exchanger 400, the heat exchange efficiency arranging the part that described first refrigerant flow can be made at front upper heat exchanger 300 is like this better than the part of described second refrigerant flow at front upper heat exchanger 300, thus be convenient to the heat exchange efficiency of balanced described first refrigerant flow and described second refrigerant flow, reduce the energy consumption of heat exchanger 1.
Therefore, according to the utility model embodiment the heat exchanger 1 for air conditioner room unit has good effect of heat exchange, noise is low, heat exchange is even, low power consumption and other advantages.
