Abstract
The utility model discloses a miniature micro-channel heat-pump-type air conditioner condenser with heating wires embedded. The miniature micro-channel heat-pump-type air conditioner condenser with the heating wires embedded comprises a heat exchanger and a heater. The heater is composed of an electric heating net formed by the heating wires. The heat exchanger is formed by an inlet pipe and an outlet pipe being connected through a micro-channel metal round pipe. The inner diameter of the micro-channel metal round pipe is within the range of 0.1-0.4mm. The heat exchanger and the heater are fixed and arranged at intervals through a guard board. The structure of the condenser is characterized in that the micro-channel metal round pipe is used as a main heat exchanging part, so that the size of the whole heat exchanger is reduced, and the heating wires are used for conducting heating on the condenser, so that the purpose of defrosting or preventing frosting is achieved.
Description
Technical field
Be used for air-cooled industrial air-conditioning, civil air conditioner and auto air-con, or the fields such as microelectronics and air-source water heater.Background technology
Present heat pump air conditioner is when heating, and outdoor pusher side, to will frosting time certain, needs commutation become refrigeration mode, makes heat exchanger heating defrost, and the defrost time can be very long under the environment of low temperature, thereby reduced the effect that heats.Existing way is to adopt the fin of electrical heating compressor, electric heating heat exchanger, shortens the defrost time, some PTC fever tablets of using, and some resistance wires of using, but because the off-premises station front face area is large, the heating power consumption is large, weak effect.
The utility model content
The purpose of this utility model is to provide a kind of volume little for the deficiency that solves above-mentioned technology, and frost-free or defrost time are short, and energy-conservation miniature microchannel heat pump type air-conditioner embeds the condenser of heating wire.
In order to achieve the above object, the designed miniature microchannel heat pump type air-conditioner of the utility model embeds the condenser of heating wire, and it comprises that heat exchanger and heater form, and is characterized in that described heater is comprised of the electric network that heating wire forms; Described heat exchanger is connected to form by miniature microchannel metal circular tube by inlet tube, outlet, and described miniature microchannel metal circular tube internal diameter is between 0.1-0.4mm; Described heat exchanger and heater are fixed by backplate and interval arranges.The characteristics of this structure are to utilize miniature microchannel metal circular tube as main heat-exchanging part, thereby reduce the volume of whole heat exchanger, and utilize heating wire to carry out appropriate heating to it, to reach defrost or to avoid the purpose of frosting.
In order to facilitate the fixing of heating wire, avoid contacting of heating wire and heat exchanger, the electric network on described heater is comprised of heating wire and fixture, and wherein said fixture can be directly fixed network, can be also fixed mount.
In order to improve the structural strength of heat exchanger, mention heat transfer effect, described miniature microchannel metal circular tube is fixed and is formed woven mesh structure by wire.
In order to adapt to the needs of various environments for use, the equipment of corresponding different capacity, described miniature microchannel heat pump type air-conditioner embeds the condenser of heating wire, comprises at least two heat exchangers, connects by the serial or parallel connection structure between described heat exchanger.
The designed miniature microchannel heat pump type air-conditioner of the utility model embeds the defrosting method of the condenser of heating wire, according to outside behaviour in service, by heating wire being continued or the gap energising, keep the temperature of heater, avoid the heat exchanger frosting or heat exchanger is carried out defrost.
The designed miniature microchannel heat pump type air-conditioner of the utility model embeds condenser and the defrosting method thereof of heating wire, by using miniature microchannel metal circular tube, improve efficiency of heat exchanger, experimental results show that, during less than 0.4mm, the macroscopic theory formula is no longer applicable when microchannel diameter.This moment, the frictional resistance of miniature microchannel metal circular tube greatly reduced, and was about the 32%-42% of macroscopic theory value; Heat flow density is up to 100-150, and general traditional heat exchange form can only reach 10-20, and the thermal efficiency greatly improves, and can reach more than 0.95; Nu Saier coefficient (power of reflection convection heat transfer' heat-transfer by convection) reaches as high as 9.20, and the traditional macro passage is up to 8.23.Simultaneously,, owing to having used miniature microchannel metal circular tube, greatly reduce the volume of heat exchanger, reduced front face area, thereby can use electric-heating-wire-heating can complete the defrost operation.Because the heat exchanger that has used miniature microchannel metal circular tube is piecemeal woven mesh structure, there is gap in centre in addition, heating wire can be arranged in intermediate space, has improved the effect of defrost, has also reduced the loss of energy.In sum, the utlity model has miniaturization, microminiaturization, be swapped out more heat in equal volume, and heating effect is good, and the defrost time is short, economical with materials, the characteristics of energy savings.
