Problems solved by technology

[0011] In addition, since the distribution part 3 of the refrigerant distributor 1 is formed by cutting, in the case of aluminum, the machinability is inferior to that of copper or brass, and machining takes time, so there is also a problem of high processing costs.

Embodiment approach 1

[0046] First, the structure of the fin-tube heat exchanger 100 using the refrigerant distributor 1 according to Embodiment 1 will be described.

[0047] figure 1 It is a block diagram of the heat exchanger using the refrigerant distributor of Embodiment 1.

[0048]The refrigerant distributor 1 according to Embodiment 1, for example, when the heat exchanger 100 functions as an evaporator, cools the two-phase refrigerant flowing into the finned tube type heat exchanger 100 composed of the heat transfer tube 50 and the fins 51 . Agents are distributed, the details will be described later. The two-phase refrigerant that has flowed into the refrigerant distributor 1 from the inflow pipe 4 branches to each outflow portion 3 a in the main body portion 3 b of the distribution portion 3 , passes through the outflow pipe 2 , and flows into the heat transfer tubes constituting each path of the heat exchanger 100 . 50.

[0049] The two-phase refrigerant flowing into the heat transfer ...

Embodiment approach 2

[0071] The refrigerant distributor 1 according to Embodiment 2 is similar to the refrigeration system according to Embodiment 1, except for the structure of each joining portion connecting the inflow pipe 4 and the inflow portion 5, the distribution portion 3 and the inflow portion 5, and the outflow pipe 2 and the outflow portion 3a. Dosage dispenser universal. Therefore, the description will mainly focus on differences from the refrigerant distributor 1 of Embodiment 1. FIG.

[0072] Figure 7 It is a vertical sectional view of the refrigerant distributor 1 according to the second embodiment.

[0073] Outflow part 3a is provided with Figure 7 The expansion part 3e whose upper end expands from the outside in such a way as to fit the outflow pipe 2 has a diameter larger than that of the outflow part 3a. Therefore, when fitting the outflow tube 2 and the extension part 3e, the outflow tube 2 is inserted into the extension part 3e, and the lower end of the outflow tube 2 abu...

Embodiment approach 3

[0085] The refrigerant distributor 1 of Embodiment 3 is basically the same as the configuration of the refrigerant distributor of Embodiment 1 except for the configuration of each joining portion that joins the outflow pipe 2 and the outflow portion 3a. Therefore, the description will mainly focus on differences from the refrigerant distributor 1 of Embodiment 1. FIG.

[0086] Figure 9 It is a vertical cross-sectional view of the refrigerant distributor 1 according to the third embodiment.

[0087] Figure 10 It is a plan view showing the dimensional relationship of the dispensing unit 3 according to the third embodiment.

[0088] Figure 11 It is a longitudinal cross-sectional view showing the dimensional relationship of the distribution unit 3 according to the third embodiment.

[0089] The main body portion 3b of the distribution portion 3 is formed by drawing (forging drawing) of a thick plate drawn by cold forging. The main body portion 3b is composed of a top plate...

Abstract

A coolant distributor that comprises: an aluminum inflow part into which coolant flows from an inflow pipe; and an aluminum distribution part that distributes to a plurality of outflow pipes the coolant that has flowed into the inflow part. The distribution part is configured from a main body part that is connected to the inflow part and from a plurality of outflow parts that are connected to the outflow pipes. The outflow parts are provided so as to protrude from the main body part and are formed integrally with the main body part.

Description

technical field [0001] The present invention relates to a refrigerant distributor and a heat pump device having the same. Background technique [0002] In a heat exchanger that functions as a condenser or evaporator of a refrigeration cycle device such as an air conditioner or a refrigeration device, when the internal refrigerant flow path is divided into multiple paths, it is necessary to install a A refrigerant distributor for distributing refrigerant to each path. [0003] In addition, for example, in a multi-type air conditioner configured by connecting a plurality of outdoor units and indoor units in parallel, a refrigerant distributor is required to distribute refrigerant from a main refrigerant flow path to each unit. [0004] In such a refrigerant distributor, from the viewpoint of further improving the performance of the air conditioner, it is desired to perform distribution to a plurality of paths more evenly and with little variation. In addition, in recent year...
