Abstract
The invention provides an air-energy water heater. The air-energy water heater comprises a water tank and a heat exchanger which exchanges heat with the water tank, wherein the heat exchanger comprises a flow-dividing pipe connected to a refrigerant inlet pipe and a collecting pipe connected to a refrigerant outlet pipe as well as a plurality of heat exchange pipes connected between the flow-dividing pipe and the collecting pipe. In a height direction of the water tank, a distance between the collecting pipe and the top of the water tank is greater than a preset value. According to the air-energy water heater, in the height direction of the water tank, the distance between the collecting pipe and the top of the water tank is greater than the preset value, so that the condition that the collecting pipe is not in contact with an empty capacity on the top of the water tank can be guaranteed, and the problems of refrigerant temperature rise and air exhaust pressure rise due to heat exchange between the collecting pipe and air inside the empty capacity are avoided, and therefore, reliability is improved.
Description
Technical field
The present invention relates to field of water heaters, in particular to a kind of air-source water heater.
Background technology
Two headers of conventional air energy water heater micro-channel heat exchanger are all symmetrically arranged, i.e.
After micro-channel heat exchanger is wrapped on water tank, two headers relative to water tank water inlet pipe and water outlet pipe pipe joint,
Working medium joint is symmetrical, it is simple to farthest increase heat exchange area.
But, it is no problem that conventional art uses on vertical air energy water-heater water tank, but when heat
When water heater tank form is horizontal hanging type, tank top has certain empty appearance, and empty part of holding is gas.And
Microchannel wraps up in effect from the bottom up can be relatively good, i.e. the parcel mode of microchannel is that two headers are upper
Side, the most up, microchannel header is arranged symmetrically with at utmost to increase and changes for pipe joint, working medium joint
Hot side amasss.But owing to sky holds also on top, easily causing coolant to hold with sky when header flows out
Gas converting heat, causes delivery temperature to raise, impacts reliability.
Summary of the invention
It is desirable to provide a kind of air-source water heater that can improve reliability.
The invention provides a kind of air-source water heater, including water tank and with the heat exchanger of water tank heat exchange,
Heat exchanger includes the isocon being connected with coolant inlet pipe and goes out the header that pipe is connected, Yi Jilian with coolant
The multiple heat exchanger tubes being connected between isocon and header；In the short transverse of water tank, header with
Distance between tank top is more than preset value.
Further, in the short transverse of water tank, the position of isocon is higher than header.
Further, water tank is that horizontal hanging type water tank, isocon and header are horizontally disposed with.
Further, heat exchanger is micro-channel heat exchanger, and multiple heat exchanger tubes are multiple Thermal Performance of Micro Channels pipes.
Further, each Thermal Performance of Micro Channels pipe is flat tube, has multiple microchannel inside flat tube.
Further, water tank includes inner bag, and heat exchanger wraps up outside the tank.
Further, water tank includes that inner bag, heat exchanger are arc-shaped, and is arranged on inside water tank.
Further, the water inlet of water tank and/or outlet are arranged on the top of water tank.
According to the air-source water heater of the present invention, by the short transverse of water tank, make header with
Distance between tank top is more than preset value, so that it is guaranteed that the empty appearance of header and tank top does not connects
Touch, it is to avoid header and the air heat-exchange within empty appearance and the rising of refrigerant temperature that causes, exhaust pressure
The problem that power increases, thus improve reliability.

Detailed description of the invention
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As depicted in figs. 1 and 2, according to the air-source water heater of the present invention, including water tank and and water tank
The heat exchanger 20 of heat exchange, heat exchanger 20 includes the isocon 21 being connected with coolant inlet pipe and goes out with coolant
The header 22 that pipe connects, and the multiple heat exchanger tubes being connected between isocon 21 and header 22
23；In the short transverse of water tank, the distance between header 22 and tank top is more than preset value.
The present invention, by the short transverse of water tank, makes the distance between header 22 and tank top big
In preset value, so that it is guaranteed that header 22 does not contacts with the empty A that holds of tank top, it is to avoid header
22 with the empty air heat-exchange held within A and the rising of refrigerant temperature that causes, pressure at expulsion increases
Problem, thus improve reliability.
Preferably, in the short transverse of water tank, the position of isocon 21 is higher than header 22, also
The most in the present invention, heat exchanger 20 is asymmetric arrangement, makes the position of isocon 21 higher than header
22, on the one hand ensure that heat exchange area, improve heat exchange property；On the other hand it also is able to ensure afflux
Pipe 22 all with water heat exchange, reduce high-pressure and delivery temperature, beneficially reliability.And,
Heat exchanger 20 structure symmetrical in compared to existing technology, also is able to shorten heat exchanger tube 23 on the whole
Length, cost-effective.
Specifically, in the present invention, water tank is horizontal hanging type water tank, the water inlet 11 of water tank and water outlet
Mouth 12 is generally located on the top of water tank.It is of course also possible to as required, by water inlet 11 with go out
12 1, the mouth of a river is arranged on tank top, a bottom being arranged on water tank.In the present invention, divide
Flow tube 21 and header 22 are horizontally disposed with, thus increase the heat-transfer surface of whole heat exchanger 20 and water tank
Long-pending.Heat exchanger 20 uses micro-channel heat exchanger, and the most multiple heat exchanger tubes 23 are multiple Thermal Performance of Micro Channels pipes.
More specifically, each Thermal Performance of Micro Channels pipe is flat tube, there is inside flat tube multiple microchannel, thus carry
High heat exchange efficiency.
Shown in Fig. 1 and Fig. 2, water tank includes inner bag 10, and usually, inner bag 10 can use
Rustless steel or pottery.In the first embodiment of the present invention, heat exchanger 20 is wrapped in outside inner bag 10
Portion, so that heat exchanger 20 and the abundant heat exchange of inner bag 10.In other embodiments of the present invention, heat exchange
Device 20 can also be arranged on inside water tank, will be bent in arc-shaped or other shapes by heat exchanger 20
Shape, increases the heat exchange area of heat exchanger 20 and water, is arranged on inside water tank by heat exchanger 20, heat exchange
Device 20 and water direct heat-exchange, it is possible to further improve heat transfer effect.
As can be seen from the above description, the above embodiments of the present invention achieve following technology effect
Really:
According to the air-source water heater of the present invention, by the short transverse of water tank, make header 22
And the distance between tank top is more than preset value, so that it is guaranteed that header 22 and the sky of tank top
Hold and do not contact, it is to avoid header 22 and the air heat-exchange within empty appearance and the liter of refrigerant temperature that causes
Height, the problem that pressure at expulsion increases, thus improve reliability.
