Abstract

The invention relates to a heat pump water heater or an air conditioner, in particular to a heat exchanger of the heat pump water heater or the air conditioner. The heat exchanger comprises a shell body, an inner cylinder and a coil, wherein the inner cylinder is arranged in the shell body; and the coil is arranged between an outer wall of the inner cylinder and an inner wall of the shell body. The inner cylinder is provided with a refrigerant storing cavity, and an outlet of a gas pipe transmitting the refrigerant is formed in the storing cavity which communicates with a shell body cavity, so that the refrigerant can enter the shell body cavity. The heat exchanger has simple and reasonable structural design, and the cavity of the inner cylinder is used as such a lower cushioning part that the refrigerant can be sprayed uniformly onto the coil surface, thus greatly improving the heat exchanging effect and even more obvious effects on high-power heat pump water heaters and air conditioners, and saving energy.

Technical field

The present invention relates to a kind of Teat pump boiler or air-conditioner, specifically relate to the heat exchanger of Teat pump boiler or air-conditioner.

Background technology

The heat exchanger of existing Teat pump boiler and air-conditioner comprises housing, inner core and coil pipe, refrigerant inlet is located on the housing sidewall, after cold-producing medium at a high speed enters the housing inner chamber from housing sidewall, cold-producing medium is not to be sprayed at coil surface uniformly, obviously greater than the import lower side, greatly reduce very big Teat pump boiler of heat exchange effect, particularly power and air-conditioner over against the refrigerant amount of inlet side, because the faster heat exchange effect that reduced more of refrigerant injection speed is not energy-conservation.

Summary of the invention

Therefore, the object of the present invention is to provide a kind of heat exchanger that makes cold-producing medium can evenly be sprayed at coil surface with raising heat exchange effect.

The object of the present invention is achieved like this:

A kind of heat exchanger, comprise housing, inner core and coil pipe, inner core is located in the housing, coil pipe is located between inner tank theca and the inner walls, be provided with a dividing plate in the described inner barrel along its cross section, the dividing plate top is the storage cavity, the dividing plate below is a reservoir compartment, the appendix outlet is passed the inner core top cover and is entered the storage cavity, the inner core that is positioned at the storage cavity side is provided with the through hole of a plurality of connection storage cavitys and housing cavity, and the inner core that is positioned at reservoir side is provided with the intercommunicating pore of a plurality of connection reservoir compartments and housing cavity, has its import of cold-producing medium efferent duct to be positioned at the reservoir compartment below.

Above-mentioned purpose also can be done further perfect by the following technical programs:

Described efferent duct outlet passes from the inner core bottom.

Described efferent duct outlet passes from dividing plate and inner core top cover.

Structural design advantages of simple of the present invention utilizes the cavity of inner core to make buffering down, makes cold-producing medium be sprayed at coil surface uniformly, improves the heat exchange effect greatly, and is more obvious to powerful Teat pump boiler and air-conditioner effect, very energy-conservation.

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples.

Embodiment 1, in conjunction with Fig. 1, the heat exchanger that a kind of Teat pump boiler is used, comprise heat-insulation layer 1, housing 2, inner core 3 and coil pipe 4, heat-insulation layer 1 parcel housing 2, described housing 2 comprises the

sealing plate

5,6 and the sidewall 22 of two-port up and down, described inner core 3 is located at up and down between two

sealing plate

5,6 inner faces, inner core 3 upper port are welded on the inner surface of upper sealing panel 5, the end face of lower seal plate 6 corresponding inner core 3 lower port is provided with a plurality of holes 7, inner core 3 is inserted in the housing 2 by hole 7 inner core 3 lower port and lower seal plate 6 are welded together again.Coil pipe 4 is located between inner core 3 outer walls and housing 2 inwalls.

Its cross section of inner core 3 upper end edges is provided with a dividing plate 8, dividing plate 8, upper sealing panel 5 and the inner core that is positioned between the two constitute cold-producing medium storage cavity 9, there is the appendix 10 of a refrigerant conveying to pass upper sealing panel and enters storage cavity 9, the appendix outlet is positioned at the storage cavity, inner core 3 is provided with the through hole 11 of a plurality of connection storage cavitys 9 and housing 2 cavitys, and cold-producing medium evenly enters housing 2 cavitys by through hole 11.

Described dividing plate 8, lower seal plate 6 and inner core between the two constitute reservoir compartment 12, the inner core bottom is provided with a plurality of intercommunicating pores 13, intercommunicating pore 13 is communicated with reservoir compartment 12 and housing 2 cavitys, have a cold-producing medium efferent duct 14 its imports to be positioned at reservoir compartment 12 belows, the other end is passed down through lower seal plate 6 and heat-insulation layer 1.Cold-producing medium enters reservoir compartment after the heat release of housing inner chamber, drain by efferent duct again.

The entrance point 15 of coil pipe 4 and the port of export 16 pass sidewall 22 and heat-insulation layer 1 respectively.

Embodiment 2, in conjunction with Fig. 2, embodiment 2 has 2 points with embodiment 1 difference, first is that upper sealing panel 5 is different with embodiment 1 with housing 2 sidewalls 22 two-port link positions with lower seal plate 6, the upper sealing panel of present embodiment and lower seal plate be in the welding of housing sidewall 22 port outer ring flange and sidewall, can solve the upper sealing panel surface like this and have ponding and have problems.Second is not both efferent duct 14 and extends up through dividing plate 8, upper sealing panel 5 and heat-insulation layer 1.
