specific Embodiment approach 1

[0015] Specific implementation mode one: combine Figure 1 to Figure 25 Describe this embodiment, a compact box-fin low-temperature heat storage heat exchanger in this embodiment includes a heat exchange body 5, a refrigerant outlet pipe 2, a refrigerant inlet pipe 6, a solar hot water outlet pipe 3, a solar hot water Inlet pipe 7, a plurality of flow equalizers 4 and a plurality of heads 1, one head 1 is respectively installed on the upper and lower sides of the heat exchange body 5, and each head 1 is provided with a flow equalizer 4 , the refrigerant outlet pipe 2 is connected to the head 1 on the upper side of the heat exchange body 5, the refrigerant inlet pipe 6 is connected to the head 1 on the other side of the lower part of the heat exchange body 5, and the solar hot water outlet pipe 3 is connected to the heat exchange body 5. The head 1 on the other side of the upper part of the body 5 is connected, and the solar hot water inlet pipe 7 is connected to the head 1 on ...

specific Embodiment approach 2

[0020] Specific implementation mode two: combination Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 To describe this embodiment, the height of the intersecting ribs 5-3-3 in this embodiment is 90%-96% of the height of the sealing plate 5-3-2. In this way, when the heat conduction plate 5-3-1 is not provided with intersecting ribs, the comprehensive thermal conductivity of the heat storage tank 5-3 is only equivalent to 20% to 30% of that at this time; when the intersecting ribs 5-3-3 When the height of the heat storage tank 5-3 is 50% of the height of the sealing plate 5-3-2, the comprehensive thermal conductivity of the heat storage tank 5-3 is equivalent to 40% to 60% of the current value; increase, the comprehensive thermal conductivity of the heat storage box 5-3 presents an upward trend, when the height of the intersecting ribs 5-3-3 is more than 96% of the height of the sealing plate 5-3-2, the comprehensive thermal conductivity of the heat...

[0021] Specific implementation mode three: combination Figure 19 , Figure 20 , Figure 21 , Figure 22 , Figure 23 and Figure 24 The present embodiment will be described. The height of the flow divider 4 in this embodiment is half of the height of the head 1 . With this setting, compared with the head without equalizer plate, the coefficient of uneven distribution of material flow drops from about 1.21 of the original head to about 0.20. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to a low-temperature heat-storage heat exchanger, in particular to a compact box-fin-type low-temperature heat-storage heat exchanger, and aims to solve the problems that an energy accumulator is large in size and difficult in improving heat exchange efficiency and is constrained by energy-storage material property, solar heat utilization has contradiction, cold / heat two-way utilization is unbalanced and operating strategy needs to be optimized in the aspects of system, equipment and method of an existing sleeve-type energy-storage multi-source heat pump integrated system. A sealing head is mounted on each of upper-portion two sides and lower-portion two sides of a heat exchange body, a flow equalizer is arranged in each sealing head, a refrigerant outlet pipe is connected with the sealing head on one side of the upper portion of the heat exchange body, a refrigerant inlet pipe is connected with the sealing head on the other side of the lower portion of the heat exchange body, a solar hot water outlet pipe is connected with the sealing head on the other side of the upper portion of the heat exchange body, a solar hot water inlet pipe is connected with the sealing head on one side of the lower portion of the heat exchange body, and the heat exchange body comprises multiple sets of heat exchange components which are mounted sequentially. The compact box-fin-type low-temperature heat-storage heat exchanger is used for low-temperature heat-storage heat exchange.

Description

technical field [0001] The invention relates to a low-temperature heat storage heat exchanger, in particular to a compact box-fin type low-temperature heat storage heat exchanger, which belongs to the technical field of energy-saving heat pump air conditioners. Background technique [0002] At present, air source heat pumps have been widely used in various regions, but there is a problem of low heating efficiency in the northern cold climate region, and there is also the problem of frosting on the outdoor heat exchanger of the heat pump cycle in regions with high outdoor relative humidity. Although a large number of air source heat pump integrated systems combining technologies in different fields have emerged, most of the integrated systems are still in the conceived stage, and only mechanically superimpose different technologies, failing to maximize strengths and avoid weaknesses in a rational combination. The multi-source heat pump technology integrating solar energy, air...
