[0002] In the field of air conditioning and chemical industry, heat exchanger is a commonly used heat exchange equipment, usually used for heat exchange or heat recovery between fluids (gas or liquid) at different temperatures to achieve energy saving and consumption reduction. Traditional heat exchangers are mainly partition-type heat exchangers, that is, cold and hot fluids flow on both sides of the partition wall, and heat exchange is carried out between the two through heat transfer between the partition walls. In actual applications, traditional heat exchangers have the problem of low heat exchange efficiency, and once the partition wall leaks, the heat exchanger and even the entire system will not operate normally, affecting production efficiency and economic practicality.

[0018] First of all, it should be explained that the directional words such as up, down, left, right, front and back described in the present invention are only described according to the drawings for the convenience of understanding, and are not intended to limit the technical solution of the present invention and the scope of protection requested.

[0019] like Figures 1 to 5 The utility model shows a first embodiment of a heat pipe type liquid heat recovery device, wherein a shell 1 with openings at both ends is provided, and the inner cavity of the shell 1 is divided into a left liquid channel 11 and a right liquid channel 12 by an insulating partition 2, and a plurality of heat pipes 3 are passed through the insulating partition 2, and a working medium for transferring heat is provided in the heat pipes 3, wherein the left half of the heat pipe 3 is an evaporation pipe section 31 located in the left liquid channel 11, and the right half of the heat pipe 3 is a condensation pipe section 32 located in the right liquid channel 12.

[0020] The above arrangement constitutes a liquid heat recovery device based on a heat pipe. In practical applications, the liquid heat recovery device provided by the utility model is correspondingly installed in the high-temperature liquid pipeline and the low-temperature liquid pipeline through the two ends of the left liquid channel 11 and the right liquid channel 12. When the high-temperature liquid and the low-temperature liquid flow through the left liquid channel 11 and the right liquid channel 12 respectively, the liquid working medium in the evaporation pipe section 31 exchanges heat with the high-temperature liquid, and the liquid working medium after absorbing heat evaporates into a gaseous working medium and enters the condensation pipe section 32, and the temperature of the high-temperature liquid after heat release decreases; the gaseous working medium entering the condensation pipe section 32 exchanges heat with the low-temperature liquid, and the gaseous working medium after heat release condenses into a liquid working medium and enters the evaporation pipe section 31, and the temperature of the low-temperature liquid after heat absorption increases. At this point, the working medium has completed an evaporation and condensation process, and transfers the heat of the high-temperature liquid to the low-temperature liquid, thereby achieving the purpose of heat recovery. Compared with the prior art, the utility model uses an insulating partition 2 to separate the inner cavity of the shell 1 into a left liquid channel 11 and a right liquid channel 12, and arranges a heat pipe 3 on the insulating partition 2 for heat transfer, which improves the heat transfer efficiency and heat recovery effect on the one hand, and improves safety and reliability and reduces maintenance costs on the other hand. When a heat pipe 3 is damaged, it only needs to remove the damaged heat pipe 3 and replace it with a new heat pipe 3 to continue using it, which solves the problem that the heat exchanger cannot be used due to leakage of the partition wall in the prior art; at the same time, the liquid heat recovery device provided by the utility model can be installed along the pipeline, does not occupy the installation space of conventional equipment, and can also increase the liquid flow by extending the length of the shell and the insulating partition as needed to improve the heat exchange and heat recovery effect, and has the advantages of simple structure, low cost, easy disassembly and assembly, and strong practicality. It should be noted that the high-temperature liquid and low-temperature liquid in this document usually refer to high-temperature water and low-temperature water, but are not limited to high-temperature water and low-temperature water, and antifreeze can also be used. It should also be pointed out that the heat pipe is a prior art in the field, and its structure and working principle are well known to technicians, and will not be repeated here.

[0021] As an optimization scheme, the present embodiment provides left conical tubes 111 sealed with the housing 1 at both ends of the left liquid channel 11, a left connecting flange 112 is provided at the end of the left conical tube 111, and a left bolt hole 113 is provided on the left connecting flange 112. This arrangement improves the convenience of installation and connection through the left connecting flange 112 and the left bolt hole 113, and the left conical tube 111 forms a spindle-shaped structure with a large middle and small ends in the left liquid channel 11, which is conducive to stabilizing the flow rate of high-temperature liquid and improving the heat exchange efficiency. Similarly, the present embodiment provides right conical tubes 121 sealed with the housing 1 at both ends of the right liquid channel 12, a right connecting flange 122 is provided at the end of the right conical tube 121, and a right bolt hole 123 is provided on the right connecting flange 122. This arrangement improves the convenience of installation and connection through the right connecting flange 122 and the right bolt hole 123, and the right conical tube 121 forms a spindle-shaped structure with a large middle and small ends in the right liquid channel 12, which is conducive to stabilizing the flow rate of low-temperature liquid and improving the heat exchange efficiency.

[0022] As a specific implementation, the utility model makes the heat pipe 3 adopt a layered arrangement on the insulation partition 2, wherein each layer includes a plurality of heat pipes 3 distributed at intervals, so as to simplify the structure and the preparation process. At the same time, the present specific implementation makes the left and right sides of the shell 1 adopt an arc structure, and accordingly, the left cone tube 111 and the right cone tube 121 both adopt a conical structure, and the left connecting flange 112 and the right connecting flange 122 both adopt a circular structure, so as to reduce the volume and occupy space.

[0023] like Figure 6 The second embodiment of the heat pipe type liquid heat recovery device of the utility model is shown. Different from the first embodiment, the heat pipe 3 is arranged in an inclined manner in the second embodiment, wherein the end of the evaporation pipe section 31 of the heat pipe 3 is lower than the end of the condensation pipe section 32. This arrangement allows the condensed working fluid to quickly flow back from the condensation pipe section 32 to the evaporation pipe section 31, thereby improving the evaporation and condensation effect and the heat recovery efficiency.

[0024] The above embodiments are only descriptions of the preferred implementation modes of the present invention, and are not intended to limit the protection scope of the present invention. Without departing from the design concept of the present invention, various modifications made by those skilled in the art based on the technical solution of the present invention should fall within the protection scope determined by the claims of the present invention.
